B12 increases mean increases in Folic Acid and B-6...is this o.k?

So if I need to take increased doses of B-12, the B-12's I take usually also include Folic Acid and B-6...are there any negative side effects to taking increased doses of the Folic Acid and B-6 as well? I.e. - If I triple up (or more) on a B-12 that provides 1,000 mcg of B-12 but also 400 mcg of Folic Acid and 2mg of B-6...is that a possible problem?
