Which foods contain tryptophan?
Foxtail millet is the richest cereal source of tryptophan. Incorporating some foxtail millet into staple foods is advisable, as it helps increase the amount of tryptophan entering the brain. Additionally, pumpkin seeds, dried tofu skin (fu zhu), dried shrimp, nori seaweed, and black sesame seeds are also rich in tryptophan.

Tryptophan aids sleep. Foods containing tryptophan promote the secretion of serotonin and melatonin and help regulate the body’s circadian rhythm, thereby exerting a sleep-promoting effect. Tryptophan is an essential nutrient involved in the synthesis of niacin and heme. It significantly boosts maternal antibody levels during pregnancy and supports lactation. Deficiency of tryptophan in the body can lead to numerous health disorders.

Low tryptophan levels are associated with anxiety, depression, and various neuropsychiatric disorders. Tryptophan is a key component involved in human DNA synthesis. A deficiency may contribute to a range of conditions—including anxiety behaviors, impaired consciousness, and mental confusion—and can also affect vascular tone. Specifically, insufficient tryptophan reduces vasoconstrictive capacity, potentially resulting in chronically low systemic arterial blood pressure. Nevertheless, the heart retains its intrinsic pumping ability. We hope this information proves helpful!
