  • High potency antioxidant protection



  • Obtained from nature's best source, 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 naturally 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.

Great Stuff Keeps an old man looking younger November 25, 2014
Best Purchase! Swanson's Ultra High Potency Astaxanthin is the best! I use it daily and feel I am getting good results from it. Swanson has good prices on all of their vitamins and this is a great product! November 18, 2014
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 June 22, 2014
tastes good I'll never buy the 4 mg.again they taste like the ocean...these taste veggie like:) May 5, 2014
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.
