Frequently Asked Questions
What is astaxanthin?
A carotenoid produced by microalgae, and the compound that gives salmon and shrimp their color. It's fat-soluble and has been studied for its antioxidant properties.† It's one well-characterized compound, not a blend.
Why 12mg when other brands use less?
Many astaxanthin supplements contain 4 to 6mg per serving. We use 12mg because that's the amount most often used in astaxanthin research.† One softgel with the full amount beats three that add up to it.
Where does your astaxanthin come from?
Ours comes from Haematococcus pluvialis microalgae, cultivated specifically for supplement use rather than synthesized. Because it's naturally sourced, it may contain trace amounts of shellfish. If you have a shellfish allergy, please consult your doctor before use.‡
How and when should I take it?
One softgel daily with a meal. Astaxanthin is fat-soluble, so food with some fat supports absorption.† Time of day doesn't matter. Consistency does.
How many servings are in a pack?
Thirty softgels. A one-month supply at one per day.
Is it third-party tested?
Yes. Every batch is tested by an independent laboratory for potency and contaminants before it leaves the facility. The certificates of analysis are published on our site.
Can I take this alongside my medication?
If you take medication, are pregnant or nursing, or have a medical condition, speak with your healthcare provider before starting any new supplement, including this one.‡
Is it suitable for vegans? Any allergens?
Gluten-free with no added sugar. Because the astaxanthin comes from microalgae, trace shellfish content is possible. See above.‡
