Astaxanthin is a deep red carotenoid pigment. It travels up the food chain: microalgae make it, small crustaceans eat the algae, and salmon, shrimp and flamingos get their pink colour from eating those crustaceans.
Where does supplement astaxanthin come from?
Most natural astaxanthin is grown from the freshwater microalga Haematococcus pluvialis. When stressed by strong light, the green algae turn red as they fill with astaxanthin, which is then extracted.
On the label
Astaxanthin is fat-soluble and is usually supplied in an oil base inside a softgel or capsule. Labels list it in milligrams per serving, commonly 4 to 12 mg, and should name the source.
What to check before you buy
- The amount of each ingredient per serving, not just per capsule
- How many capsules make one serving and how many servings are in the pack
- Whether any ingredient sits inside an undisclosed "proprietary blend"
- An FSSAI licence number and the veg/non-veg mark on the pack
