  • 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

Swanson R-Fraction Alpha Lipoic Acid is a step above traditional alpha lipoic acid supplements. 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 4.6 out of 5 by 18 reviewers.
Rated 5 out of 5 by Natural energy and skin improvement This is a wonderful product that provides energy without any jitters. I take this every other day, between other Swanson supplements. I also noticed a quick difference in my skin. It looks brighter, smoother, and less dry. Just an amazing supplement that you can actually feel working. :) March 21, 2015
Rated 5 out of 5 by Great value for a great product I now take Swanson's r-fraction alpha lipoic acid instead of the alpha lipoic acid I used to take. I love this product. It's a great value for this supplement, and I'll definitely continue to order it on a regular basis. January 13, 2014
Rated 5 out of 5 by Good Product. I first used the traditional alpha lipoic acid with mediocre results. So my healthcare professional suggested to switch to R-Fraction alpha lipoic acid to get the most beneficial effects. The beneficial effects are much greater than the traditional acid and it improved my health greatly. I can recommend this product. November 22, 2013
Rated 4 out of 5 by R-Fraction ALA I used this in response to 4Hour Body stack recommendation...not really sure if it did anything, but had no problems with this supplement (reflux, etc...). Its a low dose, so a good start for anyone new to taking this product. November 15, 2013
Rated 5 out of 5 by r fraction ALA best price and good quality product November 11, 2013
Rated 5 out of 5 by Essential I was amazed at what this product can do for your health. Swanson provides detailed info on their products and this one convinced me...it's all about health at the 'cellular" level. November 6, 2013
Rated 4 out of 5 by I take it with NAC I've been taking alpha lipoic acid for about 14 years, as it was recommended by my orthomolecular doctor as one of the most important supplements. Later I learned that taking it with NAC was even better. October 30, 2013
Rated 5 out of 5 by so glad that i found R-alpha lipoic acid 50 mg I am so glad that i found this R-alpha lipoic acid 50 mg is what i need, i decided to do what i think is the right thing to do, i am going to most certainly keep using it and paying attention to my results but i am pretty impressed with it so far, R-ALA is the active isomer of ALA in a concentrated form..higher energy levels, it's a great value supplement with a ton of added benefit, i use this everyday now, i just take a few capsules a day and within a month, it's a good supplement that i am happy to have stuck with...but even gives benefits that you just can't find in other supplements, each capsule provides me with what i need, i feel great, and look great as well..thanks swanson July 20, 2013
Rated 4 out of 5 by On the fence I guess these work. I take so many other supplements that is hard to tell. I just was told this is more effective that ALA and it is needed in our body. July 10, 2013
Rated 5 out of 5 by R-Fraction ALA I find that I do have more energy since starting to take R-Fraction. That 4 o'clock slump during the work day doesn't happen anymore for me. I feel more evenly paced with my energy level. May 13, 2013
Rated 4 out of 5 by No stomach issues here I've switched to the R-fraction form of ALA. I've found I can take a smaller dosage with the same effect as what a used to take of the regular ALA. I feel this helps me get more use out of the other vitamins I take, so I can take less of them too. Don't know for sure though. Anyway, its a regular part of my vitamin regimen. April 29, 2013
Rated 5 out of 5 by A supplement that has decent research I still use regular ALA but after a bit of research I have decided to supplement it with the R-faction version. Once again if you may not feel anything from taking it but early research shows a variety of possible long term benefits that have been proven through research. What it ultimately may do for you one can not say but it has been shown to help a variety of issues. August 3, 2011
Rated 5 out of 5 by Increase in energy, decrease appetite I have been taking 50mg R- ALA for only a week and it has given me such energy to run and do many things that I never was able to to. In addition to this, it helps me to be less hungry and able to keep my weight down. It may help with my skin, too, I am not sure, because my skin has been smoother, but I have also started using honey and another face cream about the same time so I can't tell which works to give me smoother skin. I don't plan to stop any of them so I may never know for sure. This R-ALA is great!!! It's one of the best supplements that I have ever taken with so many benefits: it helps to keep my weight where it should be and at the same time it gives me a lot of energy. Just what I was looking for! Thank you, Swanson, for making it affordable and for your great service. In fact, sometimes I bought and tried some things that didn't work for me, and I didn't return them, even the unopened bottles. I figured I didn't want to rip you guys off since you have provided us with great prices and service already (-: February 10, 2010
Rated 4 out of 5 by Good product I have acid stomach immediately after taking standard ALA. This R-fraction ALA does not cause this trouble. I like it. February 4, 2010
Rated 3 out of 5 by Has Good Potential The R-form of Alpha Lipoic Acid supposedly has some very beneficial qualities that make it worthwhile as a general supplement. I use it for its preventative qualities and any other good it may do. August 4, 2009
Rated 5 out of 5 by Best Alpha Lipoic Acid value I had previously been using one of the lower potencies of Swanson Alpha Lipoic Acid, but wanted to go to a higher level of protection. I tried the 50mg "R" fraction (SWU251) and found that I began feeling noticeably more comfortable; as if I had gained strength. Later on, I decided to try the Ultra High Potency 600mg type, just to see what kind of difference it made. However, I found it a little too strong for my particular body. So I'll be going back to the 50mg "R" fraction as my preferred choice. October 5, 2007
