Yes, to the best of my knowledge ALCAR is an amino acid. LisaBee posted the abstract of the ALCAR trial for fatigue in MS on the Natural Supports thread if you want to take a look at it.
What I should have also said but didn't is that one shouldn't automatically assume (like I did
) that your Mom's fatigue is from the MS. There are lots of other things that can cause fatigue. Hypothyroidism is one of them, but presumably her neuro is checking her thyroid function periodically since it's recommended for people on Avonex.
It's nice to see your concern for your mother's well being.
