  • High potency antioxidant protection

  • Obtained from the microalgae Haematococcus pluvialis

  • Extracted using advanced supercritical CO2 extraction methods that do not require chemical solvents

When it comes to antioxidant protection, each of us has to have enough to meet the challenges of our free-radical workload, which can depend on variables like mental and physical stress, air and water pollution, physical activity levels, concentrations of chemicals in our foods and other factors. In addition, the dietary antioxidants we depend on to defend us against free radicals tend to concentrate in certain organs or tissues, adding another consideration to the equation. This is why we've developed our new High-Potency Astaxanthin with 8 mg per softgel to help you tailor your antioxidant intake to meet your specific needs.

As a fat-soluble antioxidant, astaxanthin is particularly beneficial for the brain, skin and other organs with high concentrations of fatty acids.* In the skin, astaxanthin is especially valuable for protecting against free radicals generated by the activity of the sun's ultraviolet radiation.* It occurs in many foods, including salmon, crab and lobster (to which it provides their rich red color), but the best source by far is the microalgae Haematococcus pluvialis, which can yield 8,000 times the astaxanthin concentration found in salmon. Our astaxanthin is harvested from this unique microalgae through an advanced supercritical CO2 extraction process without the use of any chemical solvents. For optimal effectiveness, our softgels are fortified with medium-chain triglycerides (MCTs) to enhance the bioavailability of this fat-soluble nutrient.

Rated 5 out of 5 by from Helped My Tired Eyes I work with computers all day and my eyes would often get tired by the end of the day. I had read that Astaxanthin could help this problem so I tried it and I found that my eyes felt quite a bit better. The effect is noticeable quite quickly. I am happy with the results.

Rated 5 out of 5 by from Great antioxidant! I love that I can get this strength of astaxanthin in a small gel cap! I take one a day to keep me "covered". I usually try to get when on sale because it can be pricey. But Swanson's always has the best prices and great products!

Rated 2 out of 5 by from Not the same I have been extremely satisfied with every Swanson product I have tried, until now. This 8mg dose does not give me the same results as two of the 4mg BioAstin that I had been previously buying. Will continue to buy the BioAstin from Swanson

Rated 5 out of 5 by from tastes good I'll never buy the 4 mg.again they taste like the ocean...these taste veggie like:)

Rated 5 out of 5 by from POTENT PROTECTION Everything I read from all sources everywhere extolls the 'wonderfulness' of Astaxanthin as Potent and Effective Antioxidant Protection. This 8 mg. capsule is a step up from the usual 4 mg. product. I think this is a wise move. . . . More of this very good thing is a very good thing, indeed. I recommend it. Works for me.
