What does the European safety assessment say?

In 2020, EFSA concluded that 8 mg daily from supplements, together with high estimated dietary exposure, was safe for adults. This safety conclusion does not establish that 8 mg improves health. 1

Why age and other products matter

The German consumer advice centers list EU maximum daily amounts for the algal ingredient of 2.3 mg for ages 3–10, 5.7 mg for ages 11–14, and 8 mg above age 14. It is not intended for children under three, and labeling must warn against other astaxanthin-ester supplements on the same day. 2

What can short trials tell us about side effects?

The 2020 skin review reported no serious adverse events, but its studies were mostly small. That record cannot settle safety for all populations or combinations of medicines. 3

Can a capsule replace sunscreen?

Astaxanthin supplements cannot replace sunscreen with an appropriate protection factor or sunglasses, according to the German consumer advice centers. 4
