Analysis

Natural Factors Stress‑Relax 5‑HTP 100 mg time‑release caplets, 120‑count bottle, aimed at sleep and mood support.

+ Fully disclosed active doses (100 mg 5‑HTP, 70 mg calcium) + Time‑release matrix for prolonged absorption + Includes calcium, a mineral often omitted in 5‑HTP formulas + Positioned at the premium end of its category

- Contains wheat, gluten, soy, egg, fish, shellfish and tree‑nut derivatives - Includes added sugar, starch and carbohydrate gum, which may not suit low‑carb or sensitive diets

This product stands out by offering a transparent label with exact amounts of each active and a time‑release delivery that differentiates it from standard immediate‑release 5‑HTP supplements. It also adds calcium, a modest mineral contribution (~9 % NRV). However, the formulation incorporates a range of common allergens and added carbohydrates, and despite tags suggesting vegan/gluten‑free status, the ingredient list includes gluten‑containing wheat and other animal‑derived components. It is therefore a premium‑priced option best suited to users without those specific dietary restrictions.
