Product Overview

  • Bio-Enhanced Active Form of Lipoic Acid
  • Dietary Supplement
  • Suitable for Vegetarians

Super R-Lipoic Acid

Lipoic acid helps protect against oxidative stress generated by high glucose levels. Alpha-lipoic acid consists of two different forms (isomers) that have vastly different properties. The “R” form is the biologically active component (native to the body) that is responsible for lipoic acid’s phenomenal antioxidant effect. The “S” form is produced from chemical manufacture and is not very biologically active. Typical alpha-lipoic acid supplements consist of the “R” and “S” form in a 50/50 ratio. That means a 100 mg alpha-lipoic acid supplement is providing 50 mg of the biologically active “R” form.

The human body normally produces and uses the “R” form of lipoic acid. This active form, R-lipoic acid, significantly supports healthy inflammatory response, is a potent free-radical scavenger and has been shown to be more potent than the combined “R” and “S” forms that comprise most alpha-lipoic acid supplements.

Life Extension is continually searching for innovative nutritional technologies. Through dedicated research and development, the newer form of R-lipoic acid is being seen as the “next-generation” antioxidant powerhouse.

Life Extension’s Super R-Lipoic Acid has demonstrated superior bioavailability, stability, and potency for a variety of health benefits. This breakthrough converts the biologically active “R” form of lipoic acid to sodium-R-lipoic acid, which, in a recent human study achieved 10–30 times higher peak blood levels than pure R-lipoic acid. Not only does this newer lipoic acid formulation reach higher peak blood levels, it also achieves them sooner, ensuring rapid uptake from the plasma into the tissues. A recent study showed that oral ingestion of Super R-Lipoic Acid reached peak plasma concentrations within just 10–20 minutes of supplementation.

Unlike other forms of lipoic acid, Super R-Lipoic Acid is more stable in the body. The increased stability of this enhanced formulation is the reason for its greater absorption and bioavailability compared with R-lipoic acid.

The superior antioxidant effects of R-lipoic acid are already well known for supporting healthy mitochondrial function. Now, Super R-Lipoic Acid provides even more potent benefits for preserving youthful cellular energy levels.

a little early to write... but ok, why not.

Posted by Reviewer2166699 on Oct 06, 2008

So far, AMAZING. Granted, I'm taking about 1200 mg, and I'm unsure how long I'll continue at these levels, but mental clarity and overall sense of health and energy has increased dramatically, but without any let down or spike. I take in conjunction with acetyl-l-carnitine bought on this site, too, and I recommend it to all. It's difficult to find a recommended dose for either, but I recently read a 2003 study that suggest 600 mg for r-lipoic acid as an optimal maximum. If you exceed this, be sure to include a B1 supplementation.

has become a must for me

Posted by Reviewer1169052 on Sep 02, 2009

i initially began taking this as i'd read it helps with scar tissue. however, due to its blood sugar benefits, i've stopped breaking out completely. i'd had sugar, dairy, soy, and peanut-induced acne for nearly ten years and while cutting out the culprits was helpful, it did not eradicate the breakouts. this has- and i can have sugar again and still have completely clear skin. it may seem like nothing but it's been a huge change for me and i'm so grateful to have found it. also like this brand for offering the larger dosage per pill.

lowers blood sugar!

Posted by Reviewer1996189 on Dec 14, 2009

love this product, lowers blood sugar wonderfully, i can tolerate the 300mg easily, however, i read online you might only be able to take 50mg or 100mg a day cause it might give you insomnia, so i suggest starting out at a lower dosage to be on the safe side, then increase gradually to see how your body handles it.

Superior Antioxident Protection

Posted by Reviewer2754236 on Oct 19, 2009

Life Extension is known for their research and providing efficacious products. Super R-Lipoic is the 'next-generation' antioxidant. It is more bio-available and works faster than regular R-Lipoic Acid. The fact that it supports healthy mitochrondia function appeals to me. To maintain healthy cell function I use this product daily as part of my anti-aging regemin.

I am a strong believer in R-Lipoic Acid. I take 600mg per day as a therapeutic dose to support my grain free healthy diet and exercise regime to be able to manage my type 2 diabetes without drugs or insulin. Best value I have found for this dosage and 4 day delivery to Australia can't be beaten.
