  • Our most effective alpha lipoic acid supplement to date

  • Isolates the R-isomer, the only form found 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 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 5 out of 5 by from One of THE BEST Supplements Available In the 24 years I've been selling / educating the public about supplements, this advanced form of Lipoic Acid is perhaps the 2nd most versatile and effective supplement I've ever seen (only behind Pycnogenol-brand Pine Bark Extract). R-Lipoic Acid is a truly effective "healthy aging" supplement, because it helps protect your brain, eyes, blood sugar, blood vessels, liver, kidneys, and other vital organs, tissues and systems throughout your body. Government regulations keep me from giving you precise details as to the many ways R-Lipoic Acid benefits human health. Taking this with high quality vitamins C and E, and coenzyme Q10 has been proven by leading antioxidant scientists to provide your body with maximum antioxidant protection from head to toe. I honestly consider R-Lipoic Acid to be a vital part of any serious "healthy aging supplement regimen". I cannot recommend this product too strongly!

Rated 5 out of 5 by from Let me start off by saying I have been selling & evaluating supplements for nearly 25 years. With that said, of the thousands of supplements I have sold / evaluated, R-Lipoic Acid is one of my 2 all-time favorite ingredients (along with Pycnogenol pine bark extract). To say the versatility of this ingredient is extraordinary would be a huge understatement! Virtually every part of your body can benefit from R-Lipoic Acid. I would absolutely classify it as a true "anti-aging supplement". It is THAT good. Unfortunately, government regulations keep me from mentioning the specific ways it can help you ward off the many ailments associated with the aging process...both for your body and brain. But one thing I can tell you is that R-Lipoic Acid makes other antioxidants work better...specifically vitamins C and E, coenzyme Q10, glutathione, and n-acetyl-cysteine, among others. R-Lipoic Acid is also the only antioxidant native to your body that is both water- and fat-soluble. This means it works EVERYWHERE inside & outside of your 100 trillion cells. When people ask me "If there was only one supplement you could take, what would it be?", without hesitation, I tell them "R-Lipoic Acid"! This may be the single greatest endorsement I can give this extraordinary supplement . Lastly, I am a huge fan of this rare 50 mg dosage, as the typical 100 mg dose is too strong for my body.

Rated 5 out of 5 by from 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. :)

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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.
