Product Description


What is Stabilized R-Lipoic Acid?

This "racemic" mixture is the product used most often in human clinical studies on ALA, although other forms have recently become available and are beginning to be the preferred form of many ALA researchers.

Best Stabilized R-Lipoic Acid contains BioEnhanced™ Na-RALA, the sodium salt of R-Lipoic acid. Pure RLA is a very unstable molecule that has a tendency to polymerize with exposure to heat, light and moisture, turning into a sticky and ineffective product.It is also hygroscopic, or water seeking.This presents problems for those wishing to supplement with pure RLA, since any of these conditions can lead to deactivation of the beneficial activity of lipoic acid.

Unlike pure RLA, BioEnhanced™ Na-RALA is a stabilized form of RLA that will not polymerize at high temperatures, is more bioavailable and has no solvent residues.3 On a weight basis Na-RALA reaches a much higher maximum concentration in human plasma. Stability, pharmacokinetic, plasma and tissue studies reveal that commonly used 'raw' (unstabilized) R-Lipoic Acid utilized in most commercially available RLA products has very low GI absorption and bioavailability, significantly lower than even the mass-produced racemic mixture of R,S-ALA.

Na-RALA requires no refrigeration and has a shelf life of at least 3 years without polymerization. Solid R-Lipoic Acid is prone to quickly polymerize upon exposure to heat, light, and moisture.In addition,RLA is poorly soluble in water, whereas Na-RALA is completely water-soluble.

Unstabilized RLA can also contain harmful heavy metals and residual solvents that are very difficult to remove. There is a tendency for RLA to hold on to high amounts of cyclohexane, ethyl acetate or toluene, but the processing and stabilization of Na-RALA removes all traces of residual solvents from the raw material.
