Where does astaxanthin come from?
In nature, astaxanthin is made by microalgae. Small crustaceans such as krill eat the algae, and fish such as salmon eat the crustaceans, which is how the pigment moves up the food chain and gives salmon flesh its colour.
Why is astaxanthin sold in softgels?
Astaxanthin is fat-soluble, so it's typically dissolved in an oil and sealed inside a softgel. Labels usually list the oil used (for example, olive or sunflower oil).
Tip: Many fat-soluble supplements are taken with a meal. Follow the directions on your label.

Frequently asked questions
Is astaxanthin vegan?
The astaxanthin from microalgae is plant-based, but softgel shells are often made from gelatin. Check the label.
Is astaxanthin the same as beta-carotene?
Both are carotenoids, but they're different compounds. Astaxanthin is a xanthophyll and is red; beta-carotene is orange.
Why are astaxanthin softgels so dark?
Astaxanthin is an intensely coloured red pigment, so softgels often look deep red or almost black.
