Astaxanthin

The most potent and common natural source of astaxanthin is *Haematococcus pluvialis*, a type of microalgae that produces the carotenoid as a defense mechanism against harsh environmental conditions. This microalgae is commercially harvested to create high-quality dietary supplements.

Astaxanthin is a powerful carotenoid with exceptional free radical scavenging ability, and studies suggest it can be significantly more powerful than Vitamin C in certain oxidative metrics. While Vitamin C is water-soluble, astaxanthin is fat-soluble, allowing it to integrate into cell membranes to protect both the skin and eyes from UV damage.

Unlike beta-carotene, which can cause noticeable orange skin discoloration (carotenemia) when consumed in high amounts, astaxanthin typically does not cause this effect at standard supplemental dosages. Most dietary supplements contain between 4mg and 12mg, which is easily metabolized without altering skin tone.

Yes, astaxanthin is generally recognized as safe for daily consumption and is widely used to support eye health by reducing oxidative stress in the retina. Regular supplementation is often recommended at doses around 4 to 6 milligrams per day to help combat eye fatigue and support visual acuity.
