Wow you are very qualified! that's interesting, i think there maybe some conflicting opinions on if we store it or not. but science is always evolving new theories come up. they were the first things on google if you type do we store b12 in the body im not a scientist so i cant do the studies myself but find it weird they would say that actually b12 is the one vitamin we do store heaps of! i think this just shows we don't know enough about what is happening in the human body, even tho we think we do! Glad to hear you are normal now! yep this issue is very important, this is only part 1 of my post so I will take your helpful comments into consideration for part 2. thanks!
