  • Maximum 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 Maximum-Strength Astaxanthin with 12 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.

Customer Ratings & Reviews

Rated 4.4 out of 5 by 15 reviewers.
Rated 4 out of 5 by I haven't taken this supplement long enough to give a opinion based on results. Feel its a good product, but I try to buy on sale as it is pricey; hence the above rating. March 3, 2016
Rated 5 out of 5 by my skin my skin is so much clearer ever since I've started taking this daily. August 6, 2015
Rated 5 out of 5 by The recommended strength Per my fairly extensive research, 12 mg astaxanthin is the recommended strength to have the best effect. I felt better and thought more clearly when I took it previously. I have had a hard time finding this strength in any brick and mortar stores in my area and am happy to see that Swanson has it! Thanks! March 13, 2015
Rated 5 out of 5 by High potency Highest potency of this antioxidant. March 7, 2015
Rated 4 out of 5 by astaxanthin This is a good product, but a little high in mg February 19, 2015
Rated 4 out of 5 by Loyal customer I bought this product based on other reviews but I have added many new supplements so I am not sure which one is working. Generally I have been feeling more alert. December 27, 2014
Rated 3 out of 5 by Not very noticeable I take too many anti-oxidants to single out effectiveness November 5, 2014
Rated 3 out of 5 by no effect Been taking for a couple of weeks, no effect so far. October 4, 2014
Rated 3 out of 5 by Maximum Strength Astaxanthin I love this Maximum Strength Astaxanthin. Works great for me. Trouble is 30 softgels is the biggest bottle they have. Would love to see the same strenght in a larger count. Does get expensive if you add up price 12 Months of the year. August 13, 2014
Rated 5 out of 5 by My Preferred Brand This is another Great Quality Supplement from Swanson. I also have to commend Swanson for their easy to "Open and Use" supplement bottles. Most people overlook this important feature in their reviews, but I really appreciate the safety and convenience of the foil seals Swanson uses. With many other brands, it's a royal pain struggling to remove those thick paper seals that leave behind an unsealable ring on the bottle top (which sheds bits of itself with use). Swanson's foil seals are easy to cut out and leave behind a nice clean foil ring that easily seals the bottle again when the top is put back on. I highly recommend this product. July 24, 2014
Rated 5 out of 5 by Love this stuff! Like the first reviewer said, this is the very best dosage and form to take. One pill daily--it's a cute dark capsule with no weird taste, easy to swallow and 12 mg each. I have read reviews on astaxanthin that state you need oil and vitamin E to enhance the benefit. This has the oil, only needs the vitamin E to be added. I would rather take this one with a vit E pill added than look for another brand. Try one bottle like I did and you too will be back for more! January 21, 2014
Rated 5 out of 5 by I'M JAZZED I have read article upon article, from valid, reliable sources online and in print --- to Swanson's website and catalog, how fabulous an antioxidant Astaxanthin is. . . . With many saying it reigns at the top. Without gushing over the superlatives, let me just say that I have been taking the 4 mg. Astaxanthin, which I purchased from Swanson, for quite some time. I want it in my daily regimen as part of my eye health / vision program, as well as a star player on my Antioxidant Team. I would always take one a day, sometimes two of the 4 mg. Astaxanthin capsules. Then presto-zippo, along comes Swanson Health Products with this big-daddy 12 mg. Astaxanthin. I always strive to take the very best, and I take high potencies. This Swanson Ultra Maximum Strength Astaxanthin 12 mg. capsule product fulfills my wishes and needs on both fronts. Frankly, I'm very jazzed about this product. Works for me. January 18, 2014
