Facts on Astaxanthin

Human studies show that it is a potent antioxidant that protects cells against oxidative damage caused by free radicals. Unlike other carotenoids that convert to vitamin A, this one does not. (High doses of vitamin A are harmful to the body.)

Chemical Structure of Astaxanthin

It is approved by the FDA as a red food coloring for use in animal and fish foods and in Europe, it is considered a food dye. It is naturally found in salmon, krill, arctic shrimp, phaffi yeast and the microalgae Haematoccocus pluvilis.

For comparison, 4 ounces of wild sockeye salmon would contain 4.5 mg of astaxanthin and Atlantic salmon would contain 0.5 to 1.1 mg.

Research studies to support natural astaxanthin benefits

Enhances fertility in men

A well-designed clinical study involving 30 men showed that taking 16 mg daily of astaxanthin increased sperm motility and other measured sperm parameters. More importantly the fertility and pregnancy rates were significantly higher in the group taking astaxanthin.

This confirms previous animal studies that show positive benefits of astaxanthin supplements on reproductive health and fertility.

Age-related macular degeneration (AMD)

Taking a combination of astaxanthin along with vitamin C, vitamin E and several other vitamin and minerals for 12 months improved the visual function in those suffering from age-related macular degeneration.

Antioxidant benefits and immune system booster

Taking astaxanthin was shown to reduce cellular DNA damage and to boost the immune response in young health females. This benefit was seen both at 4 weeks and 8 weeks.

Acid reflux symptoms treatment

A well-designed clinical study showed that taking astaxanthin at dose of 40 mg daily was effective in reducing heartburn symptoms in 4 weeks. It was much more effective in those who were infected with the stomach bacteria H. pylori.

Skin anti-aging cure and protection

Lab studies show that astaxanthin protects against the damaging effect of UVA rays from the sun that causes the skin to age prematurely.

Researchers believe that astaxanthin could have a protective effect against sagging and wrinkles of the skin. Further studies will be needed to reconfirm all the reported health benefits of astaxanthin in protecting against skin damage and aging.

What's the difference between astaxanthin and canthaxanthin?

Canthaxanthin is another beta-carotene carotenoid like astaxanthin. It also shows similar health benefits.

Astaxanthin Side Effects and Precautions

Astaxanthin has the Generally Recognized As Safe (GRAS) status in the United States.

There are no significant side effects or toxicity from using astaxanthin even at a high dose of 20 mg daily. Other rare and minor side effects include lowering of blood pressure, hormonal changes and changes in blood counts.

When taken for long periods of time (e.g. months to years) at a high dosage there may be discoloration of the skin.
