Large doses of 1 B-Vit cause deficiencies in other B-Vits

Rather than a question, this is a request. It would be helpful to let people know that, when taking large doses of any of the B Vitamins it's an excellent idea to also supplement with a good B Complex. Since this group is synergistic, and lots of one of them will deplete some of the others, as working together pulls them all into action.
