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.

Good for skin!

Posted by Reviewer1972894 on Jan 19, 2017

I have had a nasty peri-oral dermatitis and it is said that nothing can heal it. Well, this Lipoic Acid has improved my skin incredibly! It hasn't completely disappeared but now I only get a few little bumps and not the huge, painful patches anymore! A huge thanks to this product! I will continue taking it and see what happens.....
