L-Tryptophan is an essential amino acid made from proteins during the digestion by the action of proteolytic enzymes. It promotes the production of serotonin that is involved in vasopressure regulation. It also helps regulate blood pressure, and prevents atherosclerosis. It is also involved in treating depression, anxiety, enhance mood, improve sleep, and control impulses. It may also be used for treatment of attention deficit patients. It also helps in weight loss because it curbs the cravings and suppresses appetite. L-Tryptophan also plays an important role in the production of niacin. It helps relieve and alleviate the symptoms of fibromyalgia. It also promotes the production of growth hormones and is the reason why it is used in the AMS Nocturnabol formula, but adding Gaba would have made Nocturnabol better.

Melatonin is a hormone secreted by the pineal gland in the brain regulating other hormones and circadian rhythm in the body. It determines when we sleep and when we awake. Activated by darkness, it remains suppressed during the day. Melatonin levels are age related, with children having high levels which diminish with increasing age leading to disturbed sleep in the aged. It controls the onset of menstruation and menopause in women. Melatonin is known for its antioxidant properties. Melatonin supplements prevent insomnia, improve the quality of sleep and increase morning alertness. It is known to stimulate bone growth, prevent headaches and migraines and reduce depression and anxiety. It reduces sleep disturbances in children with ADHD.

There really is not much to the Advanced Muscle Science Nocturnabol formula and I would have preferred some Gaba for Repairing muscles at night by releasing HGH like in Gaba-V, which in my opinion is a much more effective product for both sleep and HGH release.
