Reset Your Sleep Cycle for Better Rest With MelatoninIf you're having trouble getting some shuteye, taking a melatonin supplement may help you. A hormone produced by pinealocytes in the pineal gland (located in the brain), melatonin, or 5-methoxy-N-acetyltryptamine, is naturally synthesized from the amino acid tryptophan (derived from serotonin) by the enzyme 5-hydroxyindole-O-methyltransferase.
Melatonin helps regulate circadian rhythms as well as other hormones in the body, and most of biological effects of melatonin are produced by its binding to and action on melatonin receptors. This hormone also plays a role in monthly female menstruation cycles. Jet lag, shift work, or poor vision can disrupt melatonin cycles, along with exposure to bright lights at night or not enough light during the day. Individuals experiencing these conditions can benefit from using melatonin for up to two weeks.
Melatonin is available as tablets, capsules, cream and lozenges that dissolve under the tongue. Because of possible effects with other medications, talk to your doctor first before taking a melatonin supplement.
