    I'm not sure if it's this alone or a combination of the few supplements I'm taking. All I can say is I'm really happy with my blood results just after over 2 months!

    We are so glad LEF has it's high-potency RLA on iherb. This is the only R-LA we use. I believe the raw material producer is Geranova (lipoic acid specialists) and they state R-LA is FORTY TIMES better absorbed than the usual lipoic acid. This means it is much more bio-available and therefore, you don't need to take nearly as much.

    Good for what it is.

    Good R-LA.. Though next time around I'll be getting AOR Sustained Release R(+)-LA, as the half-life of this R-LA in your bloodstream is very short.

    Easy to take, no bitter taste and heartburn like I always had with LEF's dihydro-lipoic acid product

    I have a lot of faith in the Life Extension brand and even my allied health practitioners recommended it to me. So far , so good. I tolerate it well and will continue to buy this R-Lipoic.

    Good product for me

    This is the least expensive, pure R-Lipoic Acid per milligram, that I have found so far. Until I find a better deal I'l stick with this.
