A safe alternative to L-tryptophan, L5HTP (L-5-hydroxytryptophan) is a precursor to serotonin, supporting serotonin levels while respecting the body’s ability to self-regulate synthesis.† Trials involving L5HTP show a supportive role in appetite control, easing the ability to fall asleep, and aiding in mood regulation.† This 5HTP is sourced from seeds of the griffonia plant, allowing for a sustainable eco-friendly source for 5HTP. Klaire offers a 50 and 100 mg capsule.
