Harvest Twin Labs' Sleep Formula promotes a deeper, more restful sleep, allowing you to wake up feeling refreshed. Its blend of Melatonin, L-Tryptophan, 5-HTP, Chamomile, Goji, Ashwagandha, Magnesium and B6, helps you fall asleep faster and maintain consistent sleep patterns, so you can stay at your best. Melatonin is a hormone in your body that plays a role in sleep. The production and release of melatonin in the brain is connected to time of day, increasing when it's dark and decreasing when it's light. Melatonin production declines with age. L-tryptophan is an essential amino acid that helps the body make proteins and certain brain-signaling chemicals. Your body changes L-tryptophan into a brain chemical called serotonin. Serotonin helps control your mood and sleep. 5-HTP works in the brain and central nervous system by increasing the production of the chemical serotonin. Serotonin can affect sleep, appetite, temperature, sexual behavior, and pain sensation. Other Ingredients in our proprietary sleep formula include lemon balm, St Johns Wort, L-Taurine, L-Theanine, St Johns Wort, Ashwagandha, Magnesium & Gaba
