What the AI looks for in Astaxanthin Nutritional Supplements
- Source
- Choose natural astaxanthin from Haematococcus pluvialis algae, not synthetic. Human supplement research mainly uses algae-derived astaxanthin, while synthetic is mostly made for aquaculture.
- Dose
- Human studies commonly use about 4 to 12 mg per day. Products far below this range are unlikely to match the studied effect.
- Delivery
- Use an oil-based softgel and take it with a meal. Astaxanthin is fat-soluble and absorbs poorly on an empty stomach.
Brands that matter
- Nutrex Hawaii: Grows its own algae and makes BioAstin.
- AstaReal: Major ingredient supplier, sometimes named on other brands' labels.
- Sports Research: Popular consumer softgel line.
What to avoid
- Products that do not state the source of the astaxanthin.
- Krill oil sold as an astaxanthin supplement, since krill contains only trace amounts.
