That is interesting about the B12.

I've been taking a multi-vit with 200% RDAof B12 a day. When I wasn't getting B12 from the diet (recently went vegan) and not from supplements, I was waking up in the night with very bad pins and needles. Since taking the multi-vit, I haven't had that problem and have had improvement in mental symptoms.

Maybe, as a vegan, I need that amount of B12 to get the minimum. Non-vegans will get it from animal products.

Or, it could be something else in the multi-vit that is helping. Alginate alone doesn't stop the pins and needles.

I will watch how I respond to this multi-vit closely or maybe buy a b-complex and see if I get the same benefit. If not, then it's something else that is helping.
