Health notes

Astaxanthin is authorised as a food additive (colour) in the UK and the EU. EFSA has evaluated astaxanthin and it is listed on the Register of Food Additive Authorisations. JECFA has also evaluated it and set an acceptable daily intake. Evidence for specific health benefits in humans from astaxanthin consumption is still developing and often comes from studies on supplements rather than typical food intakes.
