This gluten-free, non-GMO, vegetarian supplement is designed for adults seeking natural mood and sleep support, backed by a reputable brand with strong customer satisfaction. ## Description Your body requires the essential amino acid tryptophan to produce and maintain healthy serotonin levels. But your body cannot make tryptophan on its own. Our Optimized Tryptophan Plus provides 1,000 mg of high-quality L-tryptophan per serving to encourage a healthy mood, help support optimal sleep, and promote a healthy stress response. By promoting healthy serotonin levels, L-tryptophan also promotes satiety to help support healthy weight management. Hops, L-lysine and niacin are included in this sleep supplement to support healthy tryptophan activity in the body and promote healthy cellular function. This supplement should be taken in conjunction with a healthy diet and regular exercise program. Individual results are not guaranteed, and results may vary.
