Also known as: astaxanthin

Grade C — Preliminarycarotenoidantioxidant
412 mgWith fat-containing meal

Astaxanthin is a keto-carotenoid produced by the microalgae Haematococcus pluvialis that possesses antioxidant activity 6,000 times greater than vitamin C by some measures. Clinical trials show benefits for skin health (UV protection, wrinkle reduction), exercise recovery, eye fatigue, and cardiovascular markers including reduced oxidized LDL. Its unique molecular structure allows it to span the entire cell membrane, providing comprehensive antioxidant protection.

TL;DR: Extremely potent antioxidant carotenoid. Promising for skin health and exercise recovery. Still building human evidence.
