I have been taking vitamin b12 at 1mg daily of the sublingual tablets. Is this considered a megadose? I have noticed better mood and even skin tone. However, I have also noticed more hair shedding and fallout. Do you think this could be related? Could taking too much b12 cause hair loss? I thought excess of these vitamins were just passed out through urine? Thanks.
Vitamin B12 at those doses should not cause hair loss. That isn’t a megadose. There’s a lot of B12 info that I found at VeganForum.com (via Google). But as for hair loss, I’d look elsewhere for the diagnosis… like genetic causes.
