Best Stabilized R-Lipoic Acid contains BioEnhanced Na-RALA, the sodium salt of R-Lipoic Acid (RLA). Unlike pure RLA, BioEnhanced Na-RALA is a stabilized form of RLA that won't degrade at high temperatures, is more bioavailable than regular RLA and has no solvent residues.

Lipoic acid (LA) plays an important role in glucose metabolism and energy production. Because it is soluble in both water and fat, LA is known as the "universal antioxidant." LA occurs in two forms, designated as "R" and "S." Studies suggest that RLA, the natural form, is more biologically active than the S form.

Note: The RLA in this product is stabilized with Na (sodium). However, one serving of this product contains less than 1% of the Daily Value for sodium, an insignificant contribution to dietary sources. Research suggests that sodium may impact blood pressure in some individuals only when it is consumed as sodium chloride (NaCl, table salt) and not in other forms. The sodium in this product is unlikely to affect blood pressure levels.

Take 1 - 2 capsules daily with or without food, or as directed by a nutritionally informed physician.

A water and fat soluble antioxidant

Possibly more bio- available then straight Alpha Lipoid Acid . I have been taking one or the other of these supplements for for more then 15 years now . Intend to continue using ALA or R- lipoid Acid . DB has a pharmaceutical grade ALA which I have used mostly over the years.

Not just for making your pee more expensive ! !

Posted by Sickness-ELIMINATOR on Sep 14, 2016

I've tried a few different brands and types of ALA and this is by far the best one that I have ever encountered and at a very good price. ALA is an interesting vitamin in that it comes in a variety of types even though most don't actually label which type you are getting. When traditional ALA is made synthetically it is a 50/50 blend of two different types of ALA ( R and S types). These types are mirror images of each other molecularly but, studies have shown that only the R type is actually used by the body though so most ALA supplements are actually only 50% effective and the S type is just turned into expensive pee. Some companies will filter out the R type which is better but even then most of the ALA that you take cannot be absorbed by the body. This is why this brand uses Sodium (Chemical symbol Na) to bond to the ALA which then lets the body absorb 250% more and let it actually get into the blood stream. So this product is actually chemically 5 times as effective as a R & S blend and 2.5 times more effective than an R-ALA vitamin. Search on PubMed or other medical journal sites and you'll find mountains of actual clinical evidence touting NA-R-ALA for many different reasons. I've been taking it very regularly since 05/2014 and its antioxident effects definitely have helped me stay and feel healthy even though everyone else was getting sick and it also was a clear trigger in helping me lose weight by stabilizing blood sugar levels. At first it did give me pretty bad stomach aches until I got use to it and now I can easily take it with no discomfort even without food. . . Click YES if you like this review.
