The Active Ingredient Is: Astaxanthin (Haematococcus pluvialis)

Astaxanthin is a lipid‑soluble carotenoid antioxidant sourced from the microalgae Haematococcus pluvialis. It provides a single‑ingredient focus on bioactive antioxidant activity within a natural lipid vehicle for absorption.

This form is sourced from microalgae cultivated under controlled conditions, yielding a stable, naturally occurring antioxidant used to support normal cellular protection and antioxidant status.

What Does Astaxanthin Do?

Evidence suggests astaxanthin helps protect cells from oxidative damage and supports normal skin, joint, eye, and cardiovascular health processes as part of a balanced diet, in line with EFSA‑like statements. Research indicates improvements in skin elasticity and joint comfort with daily use when paired with fat-containing meals.

Dr. Park at the University of Basel found that astaxanthin supports skin health and eye health through antioxidant and anti-inflammatory mechanisms in human studies.
