How to Choose an Astaxanthin Supplement

Not all astaxanthin supplements are created equal. Here's what to check before you buy:

(1) Source - natural astaxanthin from Haematococcus pluvialis microalgae is generally preferred over synthetic versions.

(2) Purity testing - look for brands that disclose HPLC verification or third-party lab testing.

(3) Dosage - most studies use daily doses in the low single-digit milligram range; check the label against your goals.

(4) Format - softgels for systemic support, topical products for targeted skin application, or both.

(5) Manufacturing standards - GMP certification and, where relevant, local regulatory notification (such as HSA in Singapore) are good signs of a quality-conscious brand.
