High Potency Serotonin Enhancer

L-Tryptophan is used by the brain as a precursor to serotonin and melatonin, neurotransmitters that are necessary for normal sleep. Adequate sleep is crucial for healthy immune and nervous system function. In addition, changes in the level of serotonin in the brain can impact mood and satiety.

Suggested use

Take 1 capsule daily, preferably without food, or as directed by a healthcare practitioner.

Other ingredients

Vegetable cellulose (capsule), magnesium stearate, rice flour.
