*IV Ketamine, NR, and NAD+ have been used clinically off-label for decades. They are not FDA approved for the treatment of any psychiatric or pain condition.

Astaxanthin Supplements - Which is Best?

Astaxanthin is a powerful antioxidant used in longevity protocols because it appears 100x stronger than vitamin E. Astaxanthin's ability to quench free radicals, increase insulin sensitivity, protect blood vessels, and quiet inflammation make it particularly attractive to support healthy aging. But with natural and synthetic forms of astaxanthin available, what form of astaxanthin supplement is best?

Which Astaxanthin Supplement Form is Best?

Natural astaxanthin from the algae Haematococcus pluvialis is considered superior to synthetic versions. These microalgae represent the most important commercial source for natural astaxanthin. These natural forms, like that found in algae and Antarctic krill, include a fatty acid structure (astaxanthin esters) that demonstrate enhanced stability, antioxidant activity, and bioavailability compared to free astaxanthin. Sustainable extraction methods, particularly supercritical CO₂ extraction, are increasingly common and maintain safety and efficacy.
