YANGO L-tryptophan delivers 170 mg of pure L-tryptophan per capsule, with a flexible dosage allowing up to 510 mg per day across three servings. L-tryptophan is an essential amino acid that the body cannot synthesise on its own and must therefore be obtained through diet or supplementation.

This product is encapsulated in a vegetable cellulose shell, making it fully suitable for vegans and vegetarians. With 90 capsules per pack, YANGO L-tryptophan offers a convenient and straightforward way to incorporate this essential amino acid into your daily routine.

Formulated with a single, clean ingredient and no unnecessary additives, YANGO L-tryptophan is an ideal choice for those seeking a simple, high-quality amino acid supplement that fits a variety of dietary lifestyles.
