Many issues currently with R-Lipoic and quality. One of those is the availability of bulk powders and their uncertain composition and purity. It is a common misperception that a stable salt form of R-lipoic acid can be created by simply mixing a few ingredients. Not true. The new crystalline molecular structure necessary for stability and bioavailability is not created, and consumers wind up with a useless (or worse) substance.
For those who desire to not take on the risk of the unknown, you can assure yourselves of top quality supplied by the only USA manufacturer of R-Lipoic Acid.
The web page is up, product is in stock, and best of all I managed to work out a July introductory special. 90 capsules x 100mg of R-lipoic with 150mcg of optically pure D-Biotin for only $21.95 or buy 5 or more for only $20 a bottle and get free S&H. Compare to other brands with only 60 capsules per bottle. Why risk loose powders or unknown suppliers of this valuable supplement?
