Frequently Asked Questions

Why is astaxanthin considered the strongest antioxidant?

In laboratory singlet oxygen quenching assays, astaxanthin is 6,000 times more potent than vitamin C, 550 times more than vitamin E, and 40 times more than beta-carotene. Its unique molecular structure spans the entire cell membrane, providing protection to both the inside and outside of cells. Unlike beta-carotene and other carotenoids, astaxanthin cannot become a pro-oxidant under any conditions.

Should I choose natural or synthetic astaxanthin?

Natural astaxanthin from Haematococcus pluvialis microalgae is strongly preferred. It is 20-50 times more potent as an antioxidant than synthetic astaxanthin and contains a mix of esterified forms that improve stability and absorption. Synthetic astaxanthin (commonly used in aquaculture) is free-form only and less effective. Look for brands specifying H. pluvialis source.

Can I get enough astaxanthin from salmon?

Wild salmon is the richest dietary source, providing about 3-4mg astaxanthin per 6oz serving. Eating salmon 2-3 times weekly could approach a supplemental dose, but farm-raised salmon contains synthetic astaxanthin unless specified otherwise. Shrimp, trout, and crab provide smaller amounts. Supplements guarantee consistent, natural-source dosing.
