NOW L-Tryptophan comes in vegetable capsules, with each capsule delivering 500mg of free-form L-Tryptophan. The pack contains 60 vcaps, and the nutritional information is based on a two-capsule serving providing 1g of the amino acid in total. L-Tryptophan is an essential amino acid, meaning the body cannot produce it independently — it must come from food or supplementation.
NOW is a well-established American supplement brand with a longstanding reputation for quality manufacturing. Every batch of their L-Tryptophan is tested to confirm it is free from peak E and microbial contamination, reflecting the brand’s consistent attention to product integrity. Natural colour variation between capsules may occur and is considered normal for this product.
These vcaps are suitable for those following a vegetarian or vegan diet and are a straightforward way for anyone looking to add an essential amino acid to their nutritional intake — whether that’s those focused on training, those with demanding schedules, or simply individuals who prefer supplementing alongside a balanced diet.
