BioAstin® Natural Astaxanthin is the world's best selling brand of astaxanthin for humans. It is a dietary supplement with powerful antioxidant and anti-inflammatory benefits.

Cyanotech produces BioAstin from microalgae. It was the first source of astaxanthin for human nutrition reviewed by the U.S. Food and Drug Administration (FDA). In August 1999, BioAstin completed a review by the FDA without objection and was allowed to be sold in the United States as a human dietary supplement.

Natural astaxanthin has been proven to combat inflammation in several human clinical studies involving people with:

• rheumatoid arthritis
• carpal tunnel syndrome
• joint and muscle soreness after exercise

A growing body of scientific literature demonstrates that natural astaxanthin surpasses many of the antioxidant benefits of vitamin C, vitamin E, beta-carotene and other carotenoids. Human and animal studies have shown that natural astaxanthin can:

• protect the skin from the damaging effects of ultraviolet    radiation
• enhance the immune system
• enhance energy metabolism

Research has also shown that natural astaxanthin has up to 550 times the antioxidant activity of vitamin E and 10 times the antioxidant activity of beta-carotene.
