I'm not taking Glucorell, but another r-ala product. I don't notice anything. Apparently, r-ala is a good anti-oxidant, so I guess it's not totally useless to me.
you have stumbled on the very reason for your lack of response.. glucorellr is the only properly and independently tested PURE R+ alpha lipoic. so basicallly with other r-ala.. you have no idea what you are getting.. could be racemic, could be r heavy.. who knows (probably not even the company that sold it to you)
while it has not been directly tested that material is the one from which the most negative reports have come... it is in all likelyhood R heavy -at best.. it may even be racemate.
