@SusanEllen66 Thanks for the reply. The reason I ask is your stating that you take 600 mg of ALA twice a day.

I have read from several sources that the R form of ALA is the biologically active form. So the so-called racemic mixture of ALA which contains both the the R form as well as the S form, provides half the ALA the body can use.

As you may know, R ALA is quite a bit more expensive.

I take 600 mg of R ALA at night, which has allowed me to decrease my gabapentin daily dose from 2400 mg to 900 mg. And I am trying to decrease it further.
