Frequently Asked Questions

AI
Natural astaxanthin, typically sourced from Haematococcus Pluvialis algae, is generally considered more bioavailable and potent than synthetic versions. Look for products that explicitly state the algae source on the label.
Dosage varies widely between products, which can range from 4mg to 18mg per capsule. It is advisable to check the label for the amount of active astaxanthin rather than the 'complex' weight, as the same total oil weight may contain different concentrations of the active antioxidant.
Since astaxanthin is a fat-soluble antioxidant, it is most effective when taken with a meal containing healthy fats to ensure proper absorption into the bloodstream.
