The exact function of melatonin is still poorly understood, but it is critically involved in regulating the body's circadian rhythms \"the natural biorhythm of hormone secretion\" as well as the sleep\/wake cycle. Release of melatonin is stimulated by darkness and suppressed by light. It appears that some people may under-produce melatonin at night when it is needed, and over-produce it during the day when it should be low.\u003cbr \/\u003e \u0026nbsp; \u003cbr \/\u003e Seasonal affective disorder (SAD) is associated with progressive winter depression as the days get shorter. Typically, these individuals feel depressed, slow down, and generally oversleep, overeat, crave carbohydrates and women can experience resulting hormone imbalances such as increased PMS symptoms, in the winter. Improvement progresses as days increase in length. In the summer, these same patients feel elated, active, and energetic. A lack of exposure to full-spectrum natural light appears the most logical explanation as it triggers a reduced secretion of melatonin from the pineal gland and an increased secretion of cortisol by the adrenal glands. \u003cbr \/\u003e \u003cbr \/\u003e \u003cstrong\u003e Insomnia:\u003c\/strong\u003e\u003cbr \/\u003e\u003cul\u003e\u003cli\u003eUse between late afternoon and bedtime.\u003c\/li\u003e\u003cli\u003eMelatonin plays an important role in the induction of sleep.\u003c\/li\u003e\u003cli\u003eSeveral double-blind trials have shown melatonin supplementation to be very effective in promoting sleep.\u003c\/li\u003e\u003cli\u003eLow melatonin secretion at night are thought to be an extremely common cause of insomnia in the elderly, while in younger individuals this is less of a factor.\u003c\/li\u003e\u003c\/ul\u003e\u003cdiv class=\"bd\"\u003e\u0026nbsp;\u003c\/div\u003e\u003cdiv class=\"bd\"\u003e\u003cstrong\u003eShift Workers:\u003c\/strong\u003e\u003c\/div\u003e\u003cul\u003e\u003cli\u003eMelatonin may help shift workers adjust to new sleep patterns when shifts are changing.\u0026nbsp;\u003c\/li\u003e\u003c\/ul\u003e\u003cdiv class=\"bd\"\u003e\u0026nbsp;\u003c\/div\u003e\u003cdiv class=\"bd\"\u003e\u003cstrong\u003eJet Lag: \u003c\/strong\u003e\u003c\/div\u003e\u003cul\u003e\u003cli\u003eUse during and for 5 days after travel that crosses time lines.\u003c\/li\u003e\u003cli\u003eSeveral double-blind studies have shown 3 to 5 mg of melatonin to be very effective in relieving jet lag.\u003c\/li\u003e\u003c\/ul\u003e\u003cdiv class=\"bd\"\u003e\u0026nbsp;\u003c\/div\u003e\u003cdiv class=\"bd\"\u003e\u003cstrong\u003eSeasonal Affect Disorder:\u003c\/strong\u003e\u003c\/div\u003e\u003cul\u003e\u003cli\u003eMelatonin supplementation may improve SAD because it not only increases brain melatonin levels, but also because it may suppress cortisol secretion.\u003c\/li\u003e\u003c\/ul\u003e\u003c\/div\u003e\u003c\/div\u003e\u003ch3 class=\"hd\"\u003eBenefits\u003c\/h3\u003e\u003cdiv class=\"bd\"\u003e\u003cul\u003e\u003cli\u003ePromotes positive sleep\/wake cycles\u003c\/li\u003e\u003cli\u003eEffective in relieving jet lag\u003c\/li\u003e\u003cli\u003eMay improve SAD (seasonal affect disorder)\u003c\/li\u003e\u003cli\u003eHelps shift workers adjust to new sleep patterns\u003c\/li\u003e\u003cli\u003eQuickly absorbed and utilized by the body\u003c\/li\u003e\u003c\/ul\u003e\u003c\/div\u003e\u003ch3 class=\"hd\"\u003eIngredients\u003c\/h3\u003e\u003cdiv class=\"bd\"\u003e\u003cstrong\u003e Each tablet contains \u003c\/strong\u003e\u003cbr \/\u003e Melatonin (non-animal source)...........................................5 mg\u003c\/div\u003e\u003cdiv class=\"bd\"\u003e\u0026nbsp;\u003c\/div\u003e\u003cdiv class=\"bd\"\u003e\u003cstrong\u003eNon-mecinal ingredients\u003c\/strong\u003e\u003c\/div\u003e\u003cdiv class=\"bd\"\u003eLactose monohydrate, microcrystalline cellulose, natural peppermint flavour, croscarmellose sodium, vegetable grade magnesium stearate (lubricant)\u003c\/div\u003e\u003ch3 class=\"hd\"\u003eDosage\u003c\/h3\u003e\u003cdiv class=\"bd\"\u003eAdults only.
