  • 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.

Double-Strength R-Fraction Alpha Lipoic Acid 4.8 5 10 11
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
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
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
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.

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
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.

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
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
R-ALA less acid on the stomach in the morning, and works 10x better than 'standard' ALA November 19, 2008
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
