Science of astaxanthin

Antioxidant activity

Astaxanthin has a structural similarity with beta-carotene, but a powerful difference in functionality.



Several studies have compared the antioxidant activity of astaxanthin to that of other carotenoids. Like other carotenoids, astaxanthin is a powerful scavenger of singlet oxygen. One study found that astaxanthin was twice as effective at neutralizing singlet oxygen as beta-carotene (and nearly 80 times more effective than vitamin E) in chemical solution. Lycopene, meanwhile, was 30% more effective than astaxanthin. Similar results were observed by researchers working on an in vitro system of human blood cells treated with different carotenoids and then exposed to singlet oxygen. Again, lycopene was the most effective, followed by zeaxanthin and beta-carotene.

Astaxanthin also neutralizes free radicals. One study shows that it is 50 times more effective in preventing the peroxidation of fatty acids in chemical solution than beta-carotene or zeaxanthin.

In a two-week study, five subjects received 3.6 mg/d of astaxanthin, five received 7.2 mg/d and three received 14.4 mg/d. No side effects were observed and an antioxidant effect was seen on serum LDL, with oxidation progressively slowed as astaxanthin doses increased.[4]

Why take astaxanthin every day?

Better liver function, glowing skinbrain fuel, better vision and much more...

Are you concerned about your vision?

The eye is the only organ that is constantly exposed to radiation in the form of light (sunlight in general). When this light passes through the eye, it produces free radicals at the back of the eyeball.

These free radicals can damage the cells that transmit the signal to the brain, compromising your vision. Blue light can also come from computers, televisions and smart phones.

Astaxanthin is such an important antioxidant, especially for your lipids, that you should take it every day.

Did you know that astaxanthin never becomes a pro-oxidant?

Some antioxidants can have a negative, pro-oxidant effect under certain conditions and cause oxidation in the body.

Beta-carotene, lycopene, zeaxanthin, vitamins C and E can become pro-oxidants.
