So I picked up a bottle of b12 suppliments. I read somewhere that you need 10 mcg's daily, or 2000 mcg's per week. The bottle I picked up is 500 mcg's and should be taken daily. I'm just wondering why they're 500 mcgs if you only need 10 daily. Is this common for suppliments?
Also, the brand is equate, not sure if anyone uses them or not.
