    Serotonin, an important brain neurotransmitter, is key in the regulation of appetite, mood, and melatonin production. The presence of serotonin in the brain is associated with a balanced emotional state. This is achieved in part by decreasing the activity of certain excitatory hormones, including dopamine and noradrenaline. Serotonin also acts as a satiety signal in the brain, thereby naturally regulating food intake.

    Additionally, as a precursor of melatonin, serotonin is involved in regulating sleep patterns. Serotonin is unable to cross the blood-brain barrier and is therefore synthesized in the brain. Tryptophan, an essential amino acid, is a precursor for the synthesis of serotonin. Tryptophan crosses the blood-brain barrier and is converted to L-5-Hydroxytryptophan (5-HTP), which in turn is converted into serotonin. Vitamins B2 and B6, niacinamide and Vitamin C are necessary cofactors to ensure the proper synthesis of serotonin.

    Studies indicate that supplementation with L-tryptophan may support healthy mood and restful sleep.* Other studies indicate L-tryptophan may support womens emotional well being before menstruation.* Additional research indicates L-tryptophan may be helpful in supporting healthy relaxation and occasional food cravings.

    Not 1000 mg

    I expected each of these capsules to be 1000 mg of L-tryptophan. However, you have to take 2 capsules to get 1000 mg, so they are actually 500 mg each. You end up paying more than expected for each serving and I thought this was a deceptive practice. Why not just list them as 500 mg capsules? I wrote Douglas Labs about this, but their response showed that they did not think this was a problem. I am now taking a brand of L-tryptophan that I really like, and it is actually 1000 mg per caplet.

    Great product!

    Works great. I have a lot of allergies and food sensitivities and I do just fine with this supplement. Highly recommended.
