More 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.”

L-tryptophan augmented with unique nutrients

Optimized Tryptophan Plus provides 1,000 mg of L-tryptophan per serving. Our L-tryptophan has undergone a rigorous manufacturing process to ensure quality and purity.

This formula also provides lysine, niacinamide and extracts of hops and rosemary, which may help support tryptophan benefits in the body.

Serotonin syndrome is characterized by high levels of serotonin and symptoms like confusion, sweating, agitation, nausea, involuntary muscle contractions, and racing heartbeat. Do not take L-tryptophan if you experience these symptoms. Because tryptophan may have numerous drug interactions (most commonly, MAOIs and SSRIs) consult your healthcare provider before taking this product if you are taking prescription medications.
