Thorne 5-Hydroxytryptophan 100 mg 90 Capsules – New Bottle, Exp. 02/2028

Support Healthy Serotonin Levels with Thorne 5-HTP — Paired with Active Vitamin B6

Serotonin plays a central role in mood, sleep quality, and emotional well-being — and 5-Hydroxytryptophan (5-HTP) is its direct dietary precursor. Thorne pairs 5-HTP with active Vitamin B6 (as Pyridoxal 5′-Phosphate) to support the conversion pathway, making this a thoughtfully formulated option for adults seeking mood and sleep support. This is a genuine, new-in-bottle Thorne product available now at outlet pricing through Vitamins & Supplements, alongside other deals in Health Essentials and New Arrivals.
