Tryptophan is an essential amino acid that supports sleep and mood. It helps the body produce serotonin, a neurotransmitter that influences sleep, emotions, and appetite. Found in foods like turkey, chicken, milk, and nuts, tryptophan plays a key role in relaxation, sleep, and overall mental well-being.
Individuals experiencing mood disorders, sleep disturbances, or symptoms of depression may benefit from testing their tryptophan levels, as tryptophan is a precursor to serotonin, a key neurotransmitter in mood and sleep regulation. Those on restrictive diets, particularly vegetarians and vegans, and individuals with digestive conditions affecting nutrient absorption might also benefit.
Tryptophan is found in protein-rich foods such as turkey, chicken, and other meats, as well as fish and dairy products. For plant-based sources, nuts, seeds, tofu, and legumes, particularly beans and lentils, provide tryptophan.
Tryptophan supplementation can help improve mood and sleep by boosting serotonin levels in the brain. It may aid in treating conditions like depression, anxiety, and insomnia. Additionally, tryptophan can help regulate appetite and pain tolerance.
