5-HTP (5-hydroxytryptophan) is a precursor to serotonin, the neurotransmitter that tells your brain that you are satisfied and do not need to eat more. Serotonin deficiency contributes to weight gain, depression, sleeplessness, anxiety, inflammation, and joint pain, among other symptoms. Low serotonin levels also lead to carbohydrate cravings (sugar cravings) and overeating. 5-HTP can help reduce appetite while enhancing your mood and increasing energy levels.
