DETAILED DESCRIPTION OF THE INVENTION

The present invention according to an embodiment thereof is advantageously directed towards a sleep-promoting and pain-relief composition which, for example, may induce sleep and promote the maintenance of sleep leading to a restful night's sleep, as well as alleviate minor aches and pains, further improving the quality of a person's sleep. Compounds employed in various embodiments of the present invention have been shown to be active at receptor sites in the central nervous system that relate to the induction and maintenance of sleep. Moreover, the composition of the present invention also contains compounds shown to alleviate minor aches and pains.

In an embodiment, the present invention may include the use of combinations, wherein the combination includes, without being limited to, one or more of the following: Melatonin, Coenzyme Q10, Lemon Balm leaf extract, Hops cone extract, Lavender flower extract, Passionflower extract, Skullcap, deodorized Valerian root and Willow bark extract. The supplement may be consumed in any form, e.g., a capsule, a tablet, a caplet, a liquid beverage, a powder beverage mix, or as a dietary gel. The preferred dosage form of the present embodiment is a timed release caplet.

As set forth above, the dosage form of the diet supplement, in accordance with the example embodiment set forth below, may be provided in accordance with customary processing techniques for herbal and/or dietary supplements, wherein the active ingredients are suitably processed into a desired form. In accordance with an embodiment of the present invention, one or more ingredients of the diet supplement are processed so as to form fine-milled particles. For instance, in an embodiment, one or more ingredients of the supplemental dietary composition is processed by a large-scale dry milling technique that produces fine particles, preferably known as fine-milled particles. The use of dry milling techniques, in combination with excipients and polymers, to form fine-milled particles has been shown to improve flow and dispersability, stability, resistance to moisture, bioavailability, and dissolution/release properties. Formulations may benefit by containing fine-milled particles because providing one or more ingredients in fine-milled particle sizes may optimize one or more of the flow and dispersability, stability, resistance to moisture, bioavailability, and dissolution/release properties of the one or more ingredients in a diet supplement. In vitro tests designed to simulate the environment of a stomach were performed to test the dissolution rate of fine-milled particle tablets relative to tablets having particles that are not fine-milled. These test showed that in tablets produced from fine-milled particles the time to 100% dissolution was approximately 15 minutes. In the case of non-fine-milled particle compositions, only 90% dissolution was observed after 120 minutes. In a preferred embodiment, the supplemental composition contains fine-milled particles having an average size between about 2 nm and about 50 nm.

U.S. Provisional Patent Application 60/776,325 discloses a method for improving the absorption, palatability, taste, texture, and bioavailability of compounds by increasing the solubility of compounds in proprietary formulations for the purposes of enhancing or improving muscle size, growth and/or recovery time and/or weight loss. The increased bioavailability of the compound or ingredients is achieved by reducing the particle size via "fine-milling" thereby increasing the surface area-to-volume ratio of each particle, thus increasing the rate of dissolution. The compositions and methods disclosed promote increased bioavailability by increasing the total surface area of poorly soluble particles, thereby increasing the rate of absorption.

As used herein the, term "fine-milled" and/or "fine-milling" refers to the process of micronization. Micronization is a mechanical process that involves the application of force to a particle, thereby resulting in a reduction in the size of the particle. The force, in the case of micronization, may be applied in any manner such as, e.g., the collision of particles at high rates of speed, grinding, or by an air-jet micronizer. In a preferred embodiment, fine-milled particles are obtained by jet-milling with nitrogen and compressed air.

As used herein, the term "particle size" refers to the diameter of the particle. The term "average particle size" means that at least 50% of the particles in a sample will have the specified particle size. Preferably, at least 80% of the particles in a sample will have the specified particle size, and more preferably, at least 90% of the particles in a given sample will have the specified particle size.

The size of a particle can be determined by any of the methods known within the art. Methods for particle size determination which may be employed are, e.g., sieves, sedimentation, electrozone sensing (Coulter counter), microscopy, and/or Low Angle Laser Light Scattering. The preferred methods for the particle size determination of the present invention are the methods which are most commonly used in the pharmaceutical industry, such as laser diffraction, e.g., via light scattering Coulter Delsa 440SX.

The fine-milling process may be employed in the processing of one or more of the ingredients of the present invention in the dosage forms of tablets (e.g., immediate-release film coated, modified-release and fast-dissolving), capsules (e.g., immediate-release and modified-release), liquid dispersions, powders, drink mixes, etc.

Furthermore, the dosage form of the nutritional supplement in accordance with the aforementioned embodiment or further embodiments as interpreted by one of skill in the art related to the present invention may be provided in accordance with customary processing techniques for herbal and/or dietary and/or nutritional supplements in any of the forms mentioned above.

Melatonin

Melatonin is a hormone produced by the pineal gland from tryptophan and is involved in sleep regulation (Reiter R J. melatonin: cell biology of its synthesis and of its physiological interactions. Endocr Rev. 1991 May; 12(2):151-80.). It is used to treat sleep disorders such as insomnia and `jet lag` by stimulating the release of specific pituitary hormones (Ninomiya T, Iwatani N, Tomoda A, Miike T. Effects of exogenous melatonin on pituitary hormones in humans. Clin Physiol. 2001 May; 21(3):292-9.) and adjusting the circadian rhythm to coincide with the local day and nighttime.

Melatonin supplementation has been demonstrated to be safe and effective at increasing the total amount of sleep time in healthy subjects (Matsumoto M. The hypnotic effects of melatonin treatment on diurnal sleep in humans. Psychiatry Clin Neurosci. 1999 April; 53(2):243-5.). Moreover, Melatonin has also been shown to benefit individuals suffering from insomnia (Hughes R J, Sack R L, Lewy A J. The role of melatonin and circadian phase in age-related sleep-maintenance insomnia: assessment in a clinical trial of melatonin replacement. Sleep. 1998; 21(1):52-68; Zhdanova I V, Wurtman R J, Regan M M, Taylor J A, Shi J P, Leclair O U. Melatonin treatment for age-related insomnia. J Clin Endocrinol Metab. 2001 October; 86(10):4727-30; Brzezinski A, Vangel M G, Wurtman R J, Norrie G, Zhdanova I, Ben-Shushan A, Ford I. Effects of exogenous melatonin on sleep: a meta-analysis. Sleep Med Rev. 2005 February; 9(1):41-50.) by way of the induction of sleep. The most common effect of melatonin on sleep is a reduction in sleep latency, the time taken to fall asleep (Zhdanova I V, Wurtman R J, Lynch H J, Ives J R, Dollins AB, Morabito C, Matheson J K, Schomer D L. Sleep-inducing effects of low doses of melatonin ingested in the evening. Clin Pharmacol Ther. 1995 May; 57(5):552-8; Nagtegaal J E, Kerkhof G A, Smits M G, Swart A C, Van Der Meer Y G. Delayed sleep phase syndrome: A placebo-controlled cross-over study on the effects of melatonin administered five hours before the individual dim light melatonin onset. J Sleep Res. 1998 June; 7(2):135-43; Kayumov L, Brown G, Jindal R, Buttoo K, Shapiro C M. A randomized, double-blind, placebo-controlled crossover study of the effect of exogenous melatonin on delayed sleep phase syndrome. Psychosom Med. 2001 January-February; 63(1):40-8; Buscemi N, Vandermeer B, Hooton N, Pandya R, Tjosvold L, Hartling L, Baker G, Klassen T P, Vohra S. The efficacy and safety of exogenous melatonin for primary sleep disorders. A meta-analysis. J Gen Intern Med. 2005 December; 20(12):1151-8.), wherein it reduces the time it takes for an individual to fall asleep. Melatonin may also normalize the circadian rhythm and benefit shift workers and individuals with circadian rhythm disorders (Avery D, Lenz M, Landis C. Guidelines for prescribing melatonin. Ann Med. 1998 February; 30(1):122-30; Kunz D, Mahlberg R, Muller C, Tilmann A, Bes F. Melatonin in patients with reduced REM sleep duration: two randomized controlled trials. J Clin Endocrinol Metab. 2004 January; 89(1):128-34; Mundey K, Benloucif S, Harsanyi K, Dubocovich M L, Zee P C. Phase-dependent treatment of delayed sleep phase syndrome with melatonin. Sleep. 2005 Oct. 1; 28(10):1271-8.).

Melatonin may also been shown to be effective in treating seasonal depression (Lewy A J, Bauer V K, Cutler N L, Sack R L. Melatonin treatment of winter depression: a pilot study. Psychiatry Res. 1998 Jan. 16; 77(1):57-61.) and migraines (Peres M F, Zukerman E, da Cunha Tanuri F, Moreira F R; Cipolla-Neto J. Melatonin, 3 mg, is effective for migraine prevention. Neurology. 2004 Aug. 24; 63(4):757.). Furthermore, blood pressure as well as stress hormones can be reduced by daily oral administration of melatonin in healthy men (Arangino S, Cagnacci A, Angiolucci M, Vacca A M, Longu G, Volpe A, Melis G B. Effects of melatonin on vascular reactivity, catecholamine levels, and blood pressure in healthy men. Am J Cardiol. 1999 May 1; 83(9):1417-9.).

One aspect of the present invention includes the use of Melatonin for the regulation of sleep. U.S. Pat. Nos. 6,703,412, 5,716,978, and 5,641,801 disclose methods of treating sleeplessness, sleep latency period, circadian rhythm disorders involving Melatonin.

For example, U.S. Pat. No. 6,703,412, entitled "Method of Treating Sleeplessness with Melatonin on an Acute Basis" purports to describe a method of treating sleeplessness in a human comprising the administration of an effective amount of not greater than 10 mg of melatonin or a pharmaceutically acceptable salt thereof. The method further comprises the administration of melatonin after a person has tried and failed to go to sleep, or has awakened from sleep and is unable to return to sleep. The method may be employed up to one hour from the person's desired waking time.

U.S. Pat. No. 5,716,978, entitled "Methods of Treating Circadian Rhythm Disorders" describes a method in which infants and blind humans employ the administration of Melatonin to produce a phase-shifting effect and reinstate a proper circadian rhythm. The method involves the administration of Melatonin from about 6 hours to about 19 hours prior to when a normal sleep phase should begin. The administration of Melatonin is to be less than 1 mg and at a time prior to a person's endogenous Melatonin onset time.

U.S. Pat. No. 5,641,801 entitled "Method of Reducing the Period before the Onset of Sleep" purports to describe a method of inducing sleep in an individual via the administration of a single dose of Melatonin comprising less than 1 mg to raise the peak plasma Melatonin levels to within physiological nocturnal levels of normal untreated individuals.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Melatonin. A serving of the supplemental composition may include from about 0.001 g to about 0.01 g of Melatonin. The preferred dosage of a serving of the supplemental composition comprises about 0.0040 g of Melatonin.

Furthermore, in an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include fine-milled Melatonin. A serving of the supplemental composition may include from about 0.0001 g to about 0.01 g of fine-milled Melatonin. The preferred dosage of a serving of the supplemental composition comprises about 0.0010 g of fine-milled Melatonin.

CoQ10

Coenzyme Q10 (CoQ10, ubiquinone) is found in the mitochondria of all cells and is involved in energy production. It is found at its highest concentrations in the heart, liver, kidney and pancreas. CoQ10 is a potent antioxidant in human blood (Weber C, Sejersgard Jakobsen T, Mortensen S A, Paulsen G, Holmer G. Antioxidative effect of dietary coenzyme Q10 in human blood plasma. Int J Vitam Nutr Res. 1994; 64(4):311-5.) where it also acts to preserve vitamin E, another major antioxidant (Thomas S R, Neuzil J, Stocker R. Inhibition of LDL oxidation by ubiquinol-10. A protective mechanism for coenzyme Q in atherogenesis? Mol Aspects Med. 1997; 18 Suppl:S85-103).

Due to its high concentrations in the heart, CoQ10 is believed to benefit and strengthen the heart. Many heart-related diseases are thought to result from defective myocardial energy production and numerous studies have suggested that supplementation with CoQ10 is beneficial (Mortensen S A. Perspectives on therapy of cardiovascular diseases with coenzyme Q10 (ubiquinone). Clin Investig. 1993; 71(8 Suppl):S116-23.). A meta-analysis of eight clinical trials supports the efficacy of CoQ10 for the treatment of congestive heart failure (Soja A M, Mortensen S A. Treatment of congestive heart failure with coenzyme Q10 illuminated by meta-analyses of clinical trials. Mol Aspects Med. 1997; 18 Suppl:S159-68.). Another study has shown that individuals suffering from angina were able to exercise for longer periods when receiving CoQ10 (Kamikawa T, Kobayashi A, Yamashita T, Hayashi H, Yamazaki N. Effects of coenzyme Q10 on exercise tolerance in chronic stable angina pectoris. Am J Cardiol. 1985 Aug. 1; 56(4):247-51.) as compared to untreated groups. Moreover, myocardial function was improved by CoQ10 in patients with disease conditions known to involve energy production deficits (Folkers K, Wolaniuk J, Simonsen R, Morishita M, Vadhanavikit S. Biochemical rationale and the cardiac response of patients with muscle disease to therapy with coenzyme Q10. Proc Natl Acad Sci USA. 1985 July; 82(13):4513-6.) wherein these patients also reported a `subjective` improved sense of well being. CoQ10 supplemented with iron and vitamin B6 has also appeared to prevent the progression of Alzheimer's disease, a neurological disease often associated with impaired mitochondrial function (Imagawa M, Naruse S, Tsuji S, Fujioka A, Yamaguchi H. Coenzyme Q10, iron, and vitamin B6 in genetically-confirmed Alzheimer's disease. Lancet. 1992 Sep. 12; 340(8820):671.). Moreover, in another neurological disorder, CoQ10 in a phase II clinical trial was reported to slow the progression of Parkinson's disease (Shults C W, Oakes D, Kieburtz K, Beal M F, Haas R, Plumb S, Juncos J L, Nutt J, Shoulson I, Carter J, Kompoliti K, Perlmutter J S, Reich S, Stern M, Watts R L, Kurlan R, Molho E, Harrison M, Lew M; Parkinson Study Group. Effects of coenzyme Q10 in early Parkinson disease: evidence of slowing of the functional decline. Arch Neurol. 2002 October; 59(10):1541-50.) which often results in disturbed sleep and has been shown to involve impaired mitochondrial function and low levels of CoQ10 (Shults C W, Haas R H, Passov D, Beal M F. Coenzyme Q10 levels correlate with the activities of complexes I and II/III in mitochondria from parkinsonian and nonparkinsonian subjects. Ann Neurol. 1997 August; 42(2):261-4.).

Furthermore, CoQ10 has been successfully used to treat high blood pressure, eliminating the need for medication in many cases (Langsjoen P, Langsjoen P, Willis R, Folkers K. Treatment of essential hypertension with coenzyme Q10. Mol Aspects Med. 1994; 15 Suppl:S265-72.). Migraines have also been successfully and safely treated with CoQ10 (Sandor P S, Di Clemente L, Coppola G, Saenger U, Fumal A, Magis D, Seidel L, Agosti R M, Schoenen J. Efficacy of coenzyme Q10 in migraine prophylaxis: a randomized controlled trial. Neurology. 2005 Feb. 22; 64(4):713-5.) most likely due its effects on blood pressure.

In a Japanese study, CoQ10 was shown to provide relieve from snoring in about half of the subjects, displaying a decrease in the sound level of their snoring (Takasaki Y, Yoshida H, Kaneko Y, Kaneda R, Kurosaki S, Yamadera Y., An Analysis of Effectiveness of Activated Co-enzyme Q10 on Subjects by Using Acoustic Technology. Biopharma Ltd. Tokyo Japan). Specifically, about 44% of subjects displayed a decrease in the sound level of their snoring during the REM stage of sleep, about 40% of subjects showed a decrease in the sound level of their snoring during non-REM sleep stages I/II, and about 33% of subjects showed a decrease in the sound level of their snoring during non-REM sleep stages III/IV. Furthermore, subjects reported in questionnaires that their feeling of restfulness was improved upon waking.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include CoEnzyme Q10. A serving of the supplemental composition may include from about 0.0005 g to about 0.1000 g of CoEnzyme Q10. The preferred dosage of a serving of the supplemental composition comprises about 0.0010 g of CoEnzyme Q10.

Lemon Balm Leaf Extract

The plant Melissa officinalis, commonly known as Lemon balm is a member of the mint family and is often referred to as "the calming herb". Lemon balm extract has proven antioxidant activity which likely contributes to its beneficial effects (Hohmann J, Zupko I, Redei D, Csanyi M, Falkay G, Mathe I, Janicsak G. Protective effects of the aerial parts of Salvia officinalis, Melissa Officinalis and Lavandula angustifolia and their constituents against enzyme-dependent and enzyme-independent lipid peroxidation. Planta Med. 1999 August; 65(6):576-8.). However, in the central nervous system, it possesses acetylcholine receptor activity (Wake G, Court J, Pickering A, Lewis R, Wilkins R, Perry E. acetylcholine receptor activity in European medicinal plants traditionally used to improve failing memory. J Ethnopharmacol. 2000 February; 69(2):105-14.), therefore suggesting that it may have another possible mechanism of action relating to cell-signaling.

Randomized, placebo-controlled, double-blind clinical studies investigating the acute effects of Lemon balm extract on cognition and mood have demonstrated a calming effect (Kennedy D O, Scholey A B, Tildesley N T, Perry E K, Wesnes K A. Modulation of mood and cognitive performance following acute administration of Melissa officinalis (lemon balm). Pharmacol Biochem Behav. 2002 July; 72(4):953-64.) in addition to the effect of improved mood (Kennedy D O, Wake G, Savelev S, Tildesley N T, Perry E K, Wesnes K A, Scholey A B. Modulation of mood and cognitive performance following acute administration of single doses of Melissa officinalis (Lemon balm) with human CNS nicotinic and muscarinic receptor-binding properties. Neuropsychopharmacology. 2003 October; 28(10):1871-81.). Lemon balm extract has also shown potential in reducing the negative mood effects of stress in clinical trials (Kennedy D O, Little W, Scholey A B. Attenuation of laboratory-induced stress in humans after acute administration of Melissa officinalis (Lemon Balm). Psychosom Med. 2004 July-August; 66(4):607-13.).

Moreover, the cognitive function of Alzheimer's patients has been shown to be improved by the use Lemon balm extract (Akhondzadeh S, Noroozian M, Mohammadi M, Ohadinia S, Jamshidi A H, Khani M. Melissa officinalis extract in the treatment of patients with mild to moderate Alzheimer's disease: a double blind, randomised, placebo controlled trial. J Neurol Neurosurg Psychiatry. 2003 July; 74(7):863-6.). In this study, the treatment group also displayed less agitation than the placebo group, suggesting an improvement in mood. Furthermore, clinical trials have demonstrated that Lemon balm can be effective at reducing stress and anxiety when used in combination with Valeriana (Kennedy D O, Little W, Haskell C F, Scholey A B. Anxiolytic effects of a combination of Melissa officinalis and Valeriana officinalis during laboratory induced stress. Phytother Res. 2006 February; 20(2):96-102.). Another study has shown that when presented in a lozenge also containing Lavender oil and hops, Lemon balm can alter brain-waves related to working memory, leading to the induction of a state of relaxation and an improved ability to cope with emotional and physiological stress (Dimpfel W, Pischel I, Lehnfeld R. Effects of lozenge containing lavender oil, extracts from hops, lemon balm and oat on electrical brain activity of volunteers. Eur J Med Res. 2004 Sep. 29; 9(9):423-31.).

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Lemon Balm leaf extract. A serving of the supplemental composition may include from about 0.0010 g to about 0.1000 g of Lemon Balm leaf extract. The preferred dosage of a serving of the supplemental composition comprises about 0.0800 g of Lemon Balm leaf extract.

Hops Cone Extract (Humulus lupulus)

The hop plant (Humulus lupulus) is a flowering vine used traditionally as a sedative to assist with anxiety reduction and sleep difficulties. In mice, hops extract displays sleep-enhancing and antidepressant activities (Zanoli P, Rivasi M, Zavatti M, Brusiani F, Baraldi M. New insight in the neuropharmacological activity of Humulus lupulus L. J Ethnopharmacol. 2005 Oct. 31; 102(1):102-6.).

In vitro tests have shown that hops contain compounds with antioxidant and chemoprotective activity as well as compounds that can induce detoxification enzymes (Dietz B M, Kang Y H, Liu G, Eggler A L, Yao P, Chadwick L R, Pauli G F, Farnsworth N R, Mesecar A D, van Breemen R B, Bolton J L. Xanthohumol isolated from Humulus lupulus Inhibits menadione-induced DNA damage through induction of quinone reductase. Chem Res Toxicol. 2005 August; 18(8):1296-305.).

A combination of valerian and hops has been shown to interact with adenosine receptors (Muller C E, Schumacher B, Brattstrom A, Abourashed E A, Koetter U. Interactions of valerian extracts and a fixed valerian-hop extract combination with adenosine receptors. Life Sci. 2002 Sep. 6; 71(16):1939-49.) to aid in the maintenance of sleep. Moreover, binding of the valerian-hop combination to melatonin and serotonin receptors has also been shown (Abourashed E A, Koetter U, Brattstrom A. In vitro binding experiments with a Valerian, hops and their fixed combination extract (Ze91019) to selected central nervous system receptors. Phytomedicine. 2004 November; 11(7-8):633-8.). These two receptor types are also known to be involved in the sleep process. Furthermore, hop extract has been shown to modulate the gamma-aminobutyric acid receptor (GABA(A) receptors) and display GABA-like activity (Aoshima H, Takeda K, Okita Y, Hossain S J, Koda H, Kiso Y. Effects of beer and hop on ionotropic gamma-aminobutyric acid receptors. J Agric Food Chem. 2006 Apr. 5; 54(7):2514-9.) relating to sleep. GABA is an inhibitory neurotransmitter that can induce relaxation and sleep. Modulation of any or all of these receptors may mediate the sleep-inducing activity of hops.

Most of the studies examining the efficacy of hops to aid sleep employ hops in combination with other compounds acting on various receptors known to be involved in sleep regulation. A combination of valerian and hops has been shown to reduce the time taken to fall asleep and results in a more refreshed feeling in the morning in subjects suffering from mild to moderate insomnia (Fussel A, Wolf A, Brattstrom A. Effect of a fixed valerian-Hop extract combination (Ze 91019) on sleep polygraphy in patients with non-organic insomnia: a pilot study. Eur J Med Res. 2000 Sep. 18; 5(9):385-90.).

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Hops cone extract. A serving of the supplemental composition may include from about 0.0010 g to about 0.1000 g of Hops cone extract. The preferred dosage of a serving of the supplemental composition comprises about 0.0200 g of Hops cone extract.

Lavender Flower (Lavandula officinalis)

Oil from Lavandula officinalis, commonly known as the Lavender plant is frequently used in aromatherapy as a mode to induce relaxation. The mild sedative effects of Lavender have been demonstrated in animals and humans (Lis-Balchin M, Hart S. Studies on the mode of action of the essential oil of lavender (Lavandula angustifolia P. Miller). Phytother Res. 1999 September; 13(6):540-2.). Further to the sedative effect, Lavender oil has been shown to reduce agitation of patients suffering from dementia (Holmes C, Hopkins V, Hensford C, MacLaughlin V, Wilkinson D, Rosenvinge H. Lavender oil as a treatment for agitated behaviour in severe dementia: a placebo controlled study. Int J Geriatr Psychiatry. 2002 April; 17(4):305-8.). Moreover, Lavender has also been shown be beneficial for treating depression (Akhondzadeh S, Kashani L, Fotouhi A, Jarvandi S, Mobaseri M, Moin M, Khani M, Jamshidi A H, Baghalian K, Taghizadeh M. Comparison of Lavandula angustifolia Mill. tincture and imipramine in the treatment of mild to moderate depression: a double-blind, randomized trial. Prog Neuropsychopharmacol Biol Psychiatry. 2003 February; 27(1):123-7.). Additionally, the sleep-inducing effects of other compounds may be increased by Lavender (Gyllenhaal C, Merritt S L, Peterson S D, Block K I, Gochenour T. Efficacy and safety of herbal stimulants and sedatives in sleep disorders. Sleep Med Rev. 2000 June; 4(3):229-251.).

U.S. Pat. No. 5,958,462, entitled "Therapeutic Bath Salts and Method of Use," describes a composition comprising magnesium, carbonate and copper compounds and optionally essential oils including that of Lavender. The composition comprises bath salts purported to be helpful in the relaxation of muscles, elimination or reduction of muscle spasms, and the overall enhancement of a person's mood when used as an aromatherapy.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Lavender Flower powder. A serving of the supplemental composition may include from about 0.0010 g to about 0.0100 g of Lavender Flower powder. The preferred dosage of a serving of the supplemental composition comprises about 0.0050 g of Lavender Flower powder.

Passion Flower Extract

Passion flower has been used traditionally for relaxation and as a sleep-aid as well as a treatment for anxiety. The main active component of Passionflower is thought to by chrysin, one of several flavonoids which have been isolated from this plant (Menghini A, Mancini L A. TLC determination of flavonoid accumulation in clonal populations of Passiflora incarnata L. Pharmacol Res Commun. 1988 December; 20 Suppl 5:113-6; Pereira C A, Yariwake J H, Lancas F M, Wauters J N, Tits M, Angenot L. A HPTLC densitometric determination of flavonoids from Passiflora alata, P. edulis, P. incarnata and P. caerulea and comparison with HPLC method. Phytochem Anal. 2004 July-August; 15(4):241-8.). In mice, chrysin has been shown to act as an agonist of benzodiazepine receptors and also possess anti-anxiety activity (Wolfman C, Viola H, Paladini A, Dajas F, Medina J H. Possible anxiolytic effects of chrysin, a central benzodiazepine receptor ligand isolated from Passiflora coerulea. Pharmacol Biochem Behav. 1994 January; 47(1):1-4.). Studies have shown that, in mice, Passionflower extract reduces anxiety and induces sleep (Soulimani R, Younos C, Jarmouni S, Bousta D, Misslin R, Mortier F. Behavioural effects of Passiflora incarnata L. and its indole alkaloid and flavonoid derivatives and maltol in the mouse. J Ethnopharmacol. 1997 June; 57(1):11-20.). Clinical trials in humans have further demonstrated that Passionflower is effective in the treatment of anxiety (Akhondzadeh S, Naghavi H R, Vazirian M, Shayeganpour A, Rashidi H, Khani M. Passionflower in the treatment of generalized anxiety: a pilot double-blind randomized controlled trial with oxazepam. J Clin Pharm Ther. 2001 October; 26(5):363-7.).

One aspect of the present invention includes the use of Passionflower extract for the reduction of stress and anxiety. U.S. Pat. Nos. 6,080,410 and 5,681,578 describe a method and composition, respectively, employing Passionflower extracts for the reduction of stress and anxiety.

U.S. Pat. No. 6,080,410, entitled "Method for Reducing Daily Stress and Anxiety in Adults," describes a method of employing a novel dietary supplement which serves a general relaxant comprised of Kava root extract, and at least one of Passionflower, Chamomile Flower, Hops, and Schizandra Fruit. The method claims to reduce daily stress and anxiety in adults. It is administered in capsule format.

U.S. Pat. No. 5,681,578, entitled "Composition for Relieving Stress Anxiety, Grief, And Depression," describes a composition comprising gamma Aminobutyric acid, glutamine, glycine, magnesium, passionflower, primal officinalis and vitamin B6. The composition is purported to relieve stress, anxiety, grief and depression.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Passionflower extract. A serving of the supplemental composition may include from about 0.0010 g to about 0.0100 g of Passionflower extract. The preferred dosage of a serving of the supplemental composition comprises about 0.0020 g of Passionflower extract.

Skullcap (Scutellaria lateriflora)

Scutellaria, also known commonly as Skullcap, is a member of the mint family and has been used traditionally to treat depression and stress. Studies in mice indicate that Skullcap reduces anxiety (Awad R, Arnason J T, Trudeau V, Bergeron C, Budzinski J W, Foster B C, Merali Z. Phytochemical and biological analysis of skullcap (Scutellaria lateriflora L.): a medicinal plant with anxiolytic properties. Phytomedicine. 2003 November; 10(8):640-9.). The effects of Skullcap may be at least partially mediated by antagonism of serotonin receptors (Gafner S, Bergeron C, Batcha L L, Reich J, Arnason J T, Burdette J E, Pezzuto J M, Angerhofer C K. Inhibition of [3H]-LSD binding to 5-HT7 receptors by flavonoids from Scutellaria lateriflora. J Nat Prod. 2003 April; 66(4):535-7.). A clinical study involving healthy volunteers also demonstrated that Skullcap reduces anxiety (Wolfson P, Hoffmann D L. An investigation into the efficacy of Scutellaria lateriflora in healthy volunteers. Altern Ther Health Med. 2003 March-April; 9(2):74-8.).

U.S. Pat. No. 7,045,158, entitled "Standardized Extracts of Scutellaria Laterifloa," describes an improved extract of Scutellaria Laterifloa and relates to a pharmaceutical composition prepared from said extract wherein it is suitable for treating anxiety, insomnia, convulsions, muscle tension and spasms.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Skullcap powder. A serving of the supplemental composition may include from about 0.0001 g to about 0.0100 g of Skullcap powder. The preferred dosage of a serving of the supplemental composition comprises about 0.0010 g of Skullcap powder.

Valerian Root (Valeriana officinalis)

Valeriana officinalis, wherein the root, normally called Valerian root, is a perennial herb traditionally used as a sedative and sleep-aid. Compounds from Valerian interact with GABA, melatonin, and/or adenosine systems through binding to certain melatonin and serotonin receptor subtypes (Abourashed E A, Koetter U, Braftstrom A. In vitro binding experiments with a Valerian, hops and their fixed combination extract (Ze91019) to selected central nervous system receptors. Phytomedicine. 2004 November; 11(7-8):633-8.), particularly the 5-HT.sub.5A subtype (Dietz B M, Mahady G B, Pauli G F, Farnsworth N R. Valerian extract and valerenic acid are partial agonists of the 5-HT5a receptor in vitro. Brain Res Mol Brain Res. 2005 Aug. 18; 138(2):191-7.). Interaction with this receptor is thought to be responsible for the sleep-inducing and maintenance effect of Valerian root extract.

Valerian root extract has proven to be useful in several clinical trials. Subjective self-evaluation of sleep quality improved in a valerian supplemented group as part of a randomized controlled trial (Leathwood P D, Chauffard F, Heck E, Munoz-Box R. Aqueous extract of valerian root (Valeriana officinalis L.) improves sleep quality in man. Pharmacol Biochem Behav. 1982 July; 17(1):65-71.), compared to control groups. In another clinical trial, the valerian group reported improved sleep over the placebo group, with 89% of participants reporting improved sleep (Lindahl O, Lindwall L. Double blind study of a valerian preparation. Pharmacol Biochem Behav. 1989 April; 32(4):1065-6.). Sleep was additionally improved in children with various intellectual deficits, particularly those with hyperactivity (Francis A J, Dempster R J. Effect of valerian, Valeriana edulis, on sleep difficulties in children with intellectual deficits: randomised trial. Phytomedicine. 2002 May; 9(4):273-9.).

One aspect of the present invention includes the use of Valerian for improving the quality of sleep and reducing minor aches and pains. U.S. Pat. Nos. 6,869,622 and 6,383,527 describe respective compositions for improving the quality of sleep and alleviating muscular aches and strains, particularly with respect to those in the lower back.

For example, U.S. Pat. No. 6,869,622, entitled "Composition for Improving Sleep Quality and Efficiency, And Method of Preparing and Using the Composition," describes a pharmaceutically active extract of the plant root family of Valerianaceae and its usefulness in improving sleep quality and efficiency. The patent purports to relate to a method for reducing the number of times a patient wakes after sleep onset, comprising administering to the patient a pharmaceutically-active extract of the root of a plant of the family Valerianaceae, wherein it is processed via an ethanolic and water extraction. Furthermore, a single dosage is administered between the range of 50 mg and 5000 mg approximately one-half and two hours prior to bedtime.

U.S. Pat. No. 6,383,527, entitled "Compositions Comprising Valerian Extracts, Isovaleric Acid or Derivatives Thereof with a NSAID," purports to describe a combination of valerian extract or isovaleric acid or a derivative in with a non-steroidal anti-inflammatory compound for treating acute muscular aches, strains and sprains, and in particular lower back pain.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Valerian Root. A serving of the supplemental composition may include from about 0.1000 g to about 1.000 g of Valerian Root. The preferred dosage of a serving of the supplemental composition comprises about 0.1200 g of Valerian Root.

Willow Bark Extract (Providing Salicin) (Salix alba) 25% Salicin

Willow bark (Salix alba) is a source of salicin, a precursor of acetylsalicylic acid (aspirin) traditionally used to treat pain, fever and inflammation. In a blind clinical trial, willow bark was demonstrated to be effective at relieving back pain (Chrubasik S, Eisenberg E, Balan E, Weinberger T, Luzzati R, Conradt C. Treatment of low back pain exacerbations with willow bark extract: a randomized double-blind study. Am J Med. 2000 July; 109(1):9-14.). After four weeks, 39% of the high salicin group (n=65) were pain-free, 21% of the low salicin group (n=67) were pain-free, and only 6% of the placebo group (n=59) were pain-free. Willow bark extract has also been shown to effectively reduce arthritis pain (Schmid B, Ludtke R, Selbmann H K, Kotter I, Tschirdewahn B, Schaffner W, Heide L. Efficacy and tolerability of a standardized willow bark extract in patients with osteoarthritis: randomized placebo-controlled, double blind clinical trial. Phytother Res. 2001 June; 15(4):344-50.).

The diminishment of bodily pain is an integral part of quality sleep. The inclusion of Willow Back Extract aids in the alleviation of minor bodily pains, leading to an improvement in sleep quality and a reduction in sleep disruption due to discomfort.

One aspect of the present invention includes the use of Willow bark for the attenuation of minor aches and pains, leading to an improved quality of sleep. U.S. Pat. Nos. 6,770,263 and 6,312,736 describe compositions for the treatment, e.g., alleviation, of aches and pains.

For example, U.S. Pat. No. 6,770,263, entitled "Compositions and Methods for the Treatment of Aches and Pains," purports to describe methods and compositions useful for treating aches and/or pains. The composition comprises an aqueous medium having dispersed or dissolved therein an analgesic selected from the group consisting of white willow bark, aspirin; ibuprofen, naproxen, and any combination thereof. The composition is then administered in an effective amount across a mucosal membrane.

U.S. Pat. No. 6,312,736, entitled "Herbal Composition to Relieve Pain," describes a composition used to relieve pain and other symptoms associated with migraines and other types of headaches. The composition comprises a combination of White Willow bark extract, Kava Kava root extract, Feverfew extract, Ginger root extract, Guarana extract, and Vitamin B6 wherein the composition may be combined with liposomes to carry the composition in a sublingual dosage for fast pain relief.

In an embodiment of the present invention, which is set forth in greater detail in Example 1 below, the supplemental composition may include Willow bark extract. A serving of the supplemental composition may include from about 0.1000 g to about 1.000 g of Willow bark extract.
