In terms of antioxidant power or potency, astaxanthin is 550 times stronger than vitamin E, and 6,000 times stronger than vitamin C! The first studies of the health benefits of natural astaxanthin were done on astaxanthin produced from krill oil. Cyanotech became aware of those studies as some of their customers started requesting supplement-grade astaxanthin for human consumption.

“It really caught our attention,” Dr. Cysewski says. “We started doing our own investigations, scouring the literature. And indeed, the first thing we found was that natural astaxanthin is probably the most potent natural antioxidant known.”
An important distinction is that, astaxanthin does not block UV rays, so it doesn’t prevent UVB from converting into vitamin D in your skin. It simply protects your skin against damage. Dr. Cysewski explains how:

“One of the first reactions, of course, is that UV radiation produces free radicals. The astaxanthin, as a potent antioxidant, can neutralize or quench those free radicals and stop them from causing damage, which eventually [would] lead to sunburn or to inflammation of the skin.
Astaxanthin is a carotenoid, related to beta-carotene, lutein, and canthaxanthin, but it has a unique structure, and works in some very unique ways. For example, most other antioxidants are depleted after they’ve transferred their free electrons. But astaxanthin has a massive surplus, allowing it to remain “active” far longer — at least one order of magnitude more than most other antioxidants. It donates electrons to neutralize free radicals, and then rejects the excess energy primarily as heat. But the astaxanthin remains intact — there are no chemical reactions to break it down, which is what occurs in most other antioxidants.
Astaxanthin also acts on at least five different inflammation pathways, and maintains balance within the system. Another major difference is in the number of free radicals it can handle at any given time. Most antioxidants, such as vitamin C, E and various others, can typically only handle one free radical at a time. But astaxanthin can handle multiple free radicals simultaneously – in some cases more than 19 at the same time.
“Studies have also shown that it improves blood flow and decreases blood pressure. It’s very beneficial to your heart’s mitochondria membranes, [and] can have a positive effect on blood chemistry, increasing HDL (the good cholesterol), and decreasing triglycerides.”
For comparison, four to six ounces of salmon — which contains some of the highest levels of astaxanthin — would provide about 2-3 mg. However, unless you’re eating wild caught salmon, beware that what you’re getting is synthetic astaxanthin, which is produced from petrochemicals. In fact, the synthetic astaxanthin fed to farmed salmon is not approved for human consumption, which is yet another reason to abstain from farm raised fish — especially salmon.
Make Sure Your Astaxanthin is Extracted Using Non-Toxic Methods.
Mangoes

Mangoes are rich in astaxanthin. This fruit also contains vitamins such as A and C and minerals like calcium.
Guava

Guava is another fruit high in astaxanthin. It is considered a super food because it has many vitamins and nutrients and is high in antioxidants.
Krill Oil

Krill feed on the micro-algae that produce astaxanthin. Humans consume krill in the form of krill oil supplements. Algae supplements containing astaxanthin are also available.
Shellfish

Shrimp, crawfish, crab and lobster all get their distinctive red color from the carotenoid astaxanthin. Chitosan, derived from shrimp shells, does not contain astaxanthin.
Fish

Astaxanthin is responsible for the distinctive red color of rainbow trout, salmon and salmon roe. Farm-raised salmon eat a diet supplemented with astaxanthin to ensure that they develop the expected coloring.
Vegetables and Fruit

Carrots, red peppers, and other red-pigmented vegetables and fruits contain astaxanthin.
staxanthin is a naturally occurring pigment that gives foods an orange, yellow or red color. Astaxanthin is considered a carotenoid, a class of antioxidants that includes lycopene, beta carotene and lutein. Doctor Boon Chew of Washington University has done research showing that astaxanthin stimulates the human immune system and can decrease DNA damage. Astaxanthin is found in salmon, lobster, shrimp, algae and dark-colored fruits and vegetables.
