I'm not Canadian so can't answer that
However, the brand I get here in the US at the local health/food store is Acetyl L-Carnitine 500mg manufactured by Bluebonnet Nutrition Corporation, Sugar Land, Texas.
I understand "purity" is an issue generally, so any brand you get should be certified "L carni pure".
Puzzling to me why it wouldn't be available in Canada. I thought you were more liberal than us.
Since it seems you may have an interest in "non-drug" things that might help the meaningful person in your life (I think that's wonderful by the way
), if they have burning, numbness and tingling, my pharmacist suggested alpha lipoic acid. It seems to be working like a charm for me for those symptoms.
There was a 2 week randomized, double-blind, placebo controlled pilot trial of safety, pharmokinetcs and effects on matrix metalloproteinase-9 ???? (whatever that is
). Results to be presented at the AAN at end of April. Seems to be safe ( mild gastrointestinal problems).
Conclusions from the abstract: All subjects taking ALA 1200mg had measurable levels of serum ALA while those taking 600 mg often did not. ALA was generally well tolerated.......ALA warrants further study as a potential new therapy for MS. (Lead author Vijayshree Yadav and hopefully Google can get you to the whole thing if you're interested.
Good luck to you and your friend.
