Are you supposed to supplement potassium when starting mB12 and methylfolate? I see mention of this, but don't know what it's about. I have tried to search on this site for this, but not finding info. If so, how much potassium? Is there an easy way to take it (non-pill) for my teen? What's interesting is that she has been eating a lot of bananas lately (I know they are high in Potassium), despite the fact that she really hasn't liked fruit or sweet things for quite a while.
