Most alpha lipoic acid on the shelf is a fifty-fifty mixture of two mirror-image forms, R and S. Only the R form occurs in nature and it is the one the body actually makes use of, which means half of an ordinary ALA capsule is along for the ride.

This one uses Bio-Enhanced Na-RALA, the sodium salt of R-alpha-lipoic acid. The sodium salt matters because plain R-ALA is notoriously unstable and degrades with heat and time, while the salt form holds up.

Each capsule provides 150mg of sodium-R-alpha-lipoic acid, delivering 127.5mg of R-ALA.

For adults 18 and over: one or two capsules daily on an empty stomach, or as recommended by your healthcare practitioner. Brown rice powder and silica in a hydroxypropyl methylcellulose capsule.
