Q: I live in Alberta, I can‘t seem to find Vitamin B1 or any of the other recommended supplements suggested. Does anyone know where I can get these from in Alberta Canada ? Debbie. A: Dear Debbie, thank you for your email. Unfortunately, we cannot recommend any specific brand of the protective supplements. You‘ll need to decide which kind suits your budget and needs the best. Your best bet would be to use the Canadian Amazon shop to find these products. It's up to you to make the decision on what you like and trust, we believe that there are many quality supplement brands out there. 1) Vitamin B1: https://www.amazon.ca/s?k=Vitamin+B1&ref=nb_sb_noss_2. (buy Benfotiamine if possible), 2) Alpha-lipoic acid: https://www.amazon.ca/s?k=Alpha+lipoic+acid&ref=nb_sb_noss_2., 3) Acetyl L-Carnitine: https://www.amazon.ca/s?k=Acetyl+L-Carnitine.&ref=nb_sb_noss. Like mentioned previously, if you have the opportunity, try taking Benfotiamine as your primary choice of Vitamin B1. It seems to have a stronger neuroprotective effect than Thiamine against DCA adverse reactions. You will also need to take two times lower doses of Vitamin B1.
