The Active Ingredient Is: L-Tryptophan

L-Tryptophan is basically an essential amino acid the body uses to make serotonin and melatonin, helping normal mood regulation and sleep patterns. This product offers free-form L-Tryptophan in a plant-based capsule suitable for vegetarian and vegan diets.

Source and form information show the ingredient is supplied as free-form L-Tryptophan to support normal physiological processes involved in relaxation and sleep regulation.

What Does L-Tryptophan Do?

L-Tryptophan acts as a precursor to serotonin and melatonin, which are involved in mood and sleep regulation. Scientific literature and EFSA-aligned guidance acknowledge its role in supporting these normal functions and the body’s natural sleep-wake cycle.

Dr. Richards from a UK university found that L-Tryptophan can influence sleep-related pathways, reinforcing its use as a nutrient to support relaxation and daily well-being in line with established guidance.
