Astaxanthin

Astaxanthin is a red carotenoid pigment produced by the microalga Haematococcus pluvialis. It reaches crustaceans and salmon through their food and colors them red.

Also listed as Cardax

Extract weight and astaxanthin content differ

EFSA evaluated an astaxanthin-rich extract from Haematococcus pluvialis. The total weight of that extract is different from the amount of astaxanthin itself, which is the amount used in the intake assessment. 1

Why read the rest of the ingredients?

Eye-health claims on combination products can refer to added vitamin A, riboflavin, zinc or DHA rather than astaxanthin. The German consumer advice centers draw attention to this distinction. 2
