Overview
NOW Foods' hyaluronic acid capsule (model 3151) pairs 100 mg of HA with L-proline, alpha lipoic acid and grape seed extract in one vegetarian capsule, sold in a 120-count bottle for joint and skin support.
Most single-ingredient HA capsules stop at hyaluronic acid alone; this one stacks L-proline, alpha lipoic acid and grape seed extract into the same capsule, raising the ingredient count without a stated dose comparison. It reads as a joint and skin support stack rather than a plain HA product.
- 100 mg hyaluronic acid per capsule, described as double strength
- Includes L-proline, alpha lipoic acid and grape seed extract
- Vegan, vegetarian, halal and kosher certified
- Free of dairy, egg, soy and nut allergens, non-GMO
Who it's for
Works for adults already taking an oral hyaluronic acid supplement who want the extra ingredients bundled in, including vegan, vegetarian, halal and kosher households. Not for anyone who wants an isolated HA-only capsule.
