"If you want to stay young, vibrant, active and healthy you need the powerful and lasting antioxidant power this nutrient provides. Surpasses other touted antioxidants which are price far higher ... It even softens skin and speeds recovery from strenuous exercise too." ~product review by HealthNut777

  • Our most effective alpha lipoic acid supplement to date

  • Isolates the R-isomer, the only form found naturally in the body for enhanced benefit

  • Stabilized form of R-alpha lipoic acid

For a more effective alpha lipoic acid supplement, try Swanson R-Fraction Alpha Lipoic Acid. Conventional alpha lipoic acid supplements feature a 50-50 racemic blend of R and S isomers, but the R isomer is the only form that occurs naturally in the human body, and it's the form responsible for most of alpha lipoic acid's beneficial effects. However, efforts to make an effective supplement containing only the R form have always been hampered by stability problems - until now. This form achieves maximum R-alpha lipoic acid concentrations in plasma after 30 minutes that are up to 8-10 times greater than those reached by regular (racemic) alpha lipoic acid supplements.

Rated 4.7 out of 5 by 27 reviewers.
Rated 4 out of 5 by Did not do anything for me..perhaps its my fault Been taking alpha lipoic acid almost every day for 18 months. 300mg-600mg[varied] It absolutely works. I saw improvement in about 7 days after i begun taking it. There was a week or two week periods i was out of stock and skipped taking it. My body told me it was missing the supplement. I read R-Fraction Alpha Lipoic Acid was better than alpha lipoic acid and stronger per mg Took R-Fraction Alpha Lipoic Acid 100mg[2 a day] every day for 30 days. Did not do do anything---possibly i was not taking enough of the mg. I gave an excellent quality rating because it is Swanson's brand and we know their ingredients are top notch. Satisfaction excellent. Value excellent. Effectiveness fair, but it may just be fair to me. Summary, I likely will go back to alpha lipoic acid. Although not as strong as the R-Fraction Alpha Lipoic Acid, possibly alpha lipoic acid may be more effective for some people. I dont return items as i am old fashion, i am sensitive to higher operating costs businesses have to endure. I may it another chance and even buy another bottle of R-Fraction Alpha Lipoic Acid and increase the daily dose of mg November 12, 2015
Rated 5 out of 5 by Good form of ALA The R form of ALA is best absorbed by body. Use for 60 days to feel optimum benefits. August 8, 2015
Rated 5 out of 5 by IS R-FRACTION RIGHT? I took 600 mg. of Alpha Lipoic Acid daily for a number of years. I had read a lot about how good it would be for my health, wellness, and longevity. Then along came this R-Fraction version. Everything I read about it said it was better, with more bang for the buck. It had better be, because this is only a 100 mg. capsule vs the 300 mg. and 600 mg. capsules of the straight Alpha Lipoic Acid that were previously available and which I had been using. So far, so good. I always strive to take the finest and most effective form of every nutrient I consume. I notice no difference and still feel great since switching to this allegedly better version. February 21, 2015
Rated 5 out of 5 by SwansonRAlphaLipoic So glad Swanson offers an R Alpha Lipoic acid. Have had good luck with this product. January 31, 2014
Rated 5 out of 5 by LOVE THIS SUPPLEMENT what a great supplement...keep up the good work...R type ALA is what you really want! December 28, 2013
Rated 5 out of 5 by R-Fraction Alpha Lipoic Acid My wife and I are taking R-Fraction Alpha Lipoic Acid together with Swanson Ubiquinol and Acetyl L-Carnitine and of course Supreme C and Vitamin D3. These provided us the best optimum Anti-Oxidant combinations. December 18, 2013
Rated 5 out of 5 by Super Awesome Youth Elixir & Antioxidant! 8vD If you want to stay young, vibrant, active and healthy you need the powerful and lasting antioxidant power this nutrient provides. Surpasses other touted antioxidants which are price far higher and you will notice immediate improvements when taking this for a few days. It even softens skin and speeds recovery from strenuous exercise too. November 24, 2013
Rated 5 out of 5 by R Lipoic This has been of such a great help to me in so many ways! Thanks Swansons for making such a great product! May 30, 2013
Rated 5 out of 5 by Terrific R-Fraction ALA is the most bio-available form of this essential nutrient. Wouldn't be without it. Yes, it's more costly than conventional ALA, but it is much more powerful and effective. It is best taken with 5mg of Biotin. April 24, 2013
Rated 5 out of 5 by Important In my quest for the "right stuff", as an aging male, I came across data that revealed this form of Alpha Lipoic Acid to be the best fit, best value for me (over 40). The R-Fraction is much more bio-available. April 11, 2013
Rated 5 out of 5 by Best form of ALA Love this product. and am learning that I should have ordered more. Superantioxidant that keeps me healthy. R-Fraction is the best and most powerful form of ALA. March 31, 2013
Rated 1 out of 5 by Soy allergy This product would be perfect if not for the soybean oil. It's just enough to cause my heart palpitations and inflammation; for which I have to take benadryl. March 16, 2013
Rated 5 out of 5 by Best ALA Research shows this is by far the best ALA available on the market. There is just no way to know if it really works! Hoping its long term benefits are true - only time will tell. Swanson's has the best price. February 14, 2013
Rated 4 out of 5 by Swanson pricing better than large retailer! I have found these products increase mobility and longevity during extended days or task. They improve my overall stamina and resistance to extended effects and allows normal refreshment after restful sleep and recovery. Swanson is a great service to me in aplomb shipping and very reasonable pricing compared to large retailers. February 11, 2013
Rated 5 out of 5 by didn't expect such a great response I decided to take lipoic acid in combination with vitamin E (the mixed kind) and acetyl-L-Carnitine all together. I thought it would take weeks or even months before I could see any results but to my surprise within 24 hours I started seeing clear results. First the energy level was up, the same with my wife. My complexion was a lot better, just that made me really happy! I noticed that I don't get the same effect or not as strong when I take two of the three. September 3, 2012
Rated 5 out of 5 by great product at fraction of others price This has worked for me and I do not like to be without it . Thank you Swanson. August 30, 2011
Rated 5 out of 5 by Best product of it's type The cheapest stabilized R-ALA product (on a cost-per-dose basis) I could find online after looking extensively. Quality however is not lower than other products. January 22, 2011
Rated 4 out of 5 by ALA This supplement was recommended by my doctor, Swanson offered what I needed at an affordable price and my order shipped very quickly so I an very satisfied. The only difficulty is that the white capsule looks exactly like another item I order from Swanson so they are easily mistaken for each other. July 12, 2010
Rated 5 out of 5 by R-ALA I switched to R-Fraction ALA 18 months ago after using mixed ALA for five years. R-ALA is the only form found in nature and is ten times as efficient as mixed ALA in my humble opinion. ALA is the universal antioxidant that is both water and oil soluble and regenerates vitamin C and E. ALA generates the master antioxidant, glutathione, that is not readily absorbed when taken orally. March 20, 2010
Rated 5 out of 5 by i use it nuff said i have use ALA for 7 years this is the best i have found for the money. Thanx Swanson October 17, 2009
Rated 4 out of 5 by Better form of supplement I started using ALA at the suggestion of my health care practitioner. I found that the product I purchased at the drug store without the R-fraction caused an acid stomach. After reading another review on this site, I decided to try this R-fraction product. I don't have any trouble with it and will wait a bit longer to see if it is effective as a supplement. August 23, 2009
Rated 5 out of 5 by Lipoic Acid This form of alpha lipoic acid is the only form to take as the R form is the only form that is proven to provide all the benefits of lipoic acid including maintaining health blood sugar and healthy insulin response; boosting glutathione in cells which is a master antioxidant required and made in every cell in the body and particularly the liver; and providing improved mitchondrial antioxidant protection and energy levels. Regenerates C and E and is effective in fat and water soluble locations in cells along with being a proven antiaging nutrient with much research. August 18, 2009
Rated 5 out of 5 by Best form of ALA According to the research this is the best of ALA around. Swanson has the best price for this so its a no brainer. There is no way to know if it really works but I am going to believe in the research and hope it has long term benefits. July 30, 2009
Rated 5 out of 5 by R-ALA less acid on the stomach in the morning, and works 10x better than 'standard' ALA November 19, 2008
Rated 5 out of 5 by unbelievable value I hae been taking all kinds of supplements for quite a few years. This active fraction of Alpha Lipoic acic is by far the best price/value I have ever seen. Those of you who don't do as much research as I do should know that this is as close to the fountain of youth that you will come. July 2, 2008
