L-Tryptophan is an essential amino acid, meaning your body cannot produce it on its own and you obtain it through your diet. Vit4ever provides 500 mg of pure L-tryptophan per capsule, in a plant-based capsule. One bottle contains 365 capsules, a generous supply for an entire year at one capsule per day.
Each capsule provides a fixed dose of 500 mg of L-tryptophan. In food, tryptophan is found in turkey, chicken, eggs, dairy, nuts, and pumpkin seeds, among others. L-tryptophan is the only amino acid in this capsule; no other amino acids or vitamins have been added. This makes it easy to combine with other supplements without consuming overlapping ingredients.
Tryptophan belongs to the amino acids with a ring structure, a so-called aromatic side chain, which chemically distinguishes it from, for example, lysine or proline. Vit4ever uses pure L-tryptophan without binding to other substances, so the capsule provides a single, measurable amount. The ring structure also makes the molecule sensitive to degradation by light and heat, which partly explains why light-protected, cool storage is recommended for this type of amino acid supplement.
The formula is deliberately simple: L-tryptophan in a plant-based capsule with a few excipients, without artificial colors, fragrances, or flavorings. You can find the full list of ingredients further down on this page. This makes this L-tryptophan suitable for vegans and vegetarians, and for those who choose a supplement with a short list of ingredients. The capsule shell consists of hydroxypropyl methylcellulose, a plant-based alternative to the gelatin used in traditional capsules. Those who prefer not to have animal-derived components in a supplement do not need to worry about the origin of the capsule shell with this product. People who do not use gelatin for religious or ethical reasons can also take these capsules without concern.
With 365 capsules, one bottle provides a supply for an entire year at one capsule per day. This is practical and results in less packaging waste compared to smaller bottles that you would have to reorder more frequently. Each batch is independently tested for content and purity, so that the amount of L-tryptophan in the capsule matches what is stated on the label. For those using a standalone amino acid supplement for the first time, the simplicity of this product is a practical starting point: one substance, one dosage, one capsule per day. Stick to the recommended daily amount on the label.
In short: a single amino acid supplement with 500 mg of pure L-tryptophan per capsule, vegan in composition, and with a year's supply in a single bottle. For those specifically looking for this particular amino acid, without additional vitamins or herbal extracts, this is a clear starting point within the Vit4ever range.
