More facts about Optimized Tryptophan Plus
Serotonin is a neurotransmitter in the brain associated with positive mood and restful sleep. Your body requires the essential amino acid tryptophan to produce and maintain healthy serotonin levels. But your body cannot make tryptophan on its own.
Sleep, stress response, and satiety
Studies indicate that tryptophan promotes healthy sleep patterns and mood. It also encourages the body’s healthy response to stress. And tryptophan and serotonin can help support satiety, the feeling of being “full.”
