Where does astaxanthin come from?
Microalgae. It is the pigment that gives salmon and shrimp their colour, and supplement versions are generally grown from algae rather than extracted from seafood.
Is it suitable for vegetarians?
The astaxanthin usually is, but the softgel capsule may not be. Check the individual product page.
Should I take it with food?
Yes – it is fat soluble, so a meal containing some fat helps.
Is 8mg better than 5mg?
It is more. Work out the cost per milligram across pack sizes before deciding which is better value.
