B vitamins in general
B vitamins are water-soluble and because they do not get stored in the body, we humans depend on regular intake of them. B vitamins work in synergy in a highly complicated teamwork setup. They take part in most of the body's enzymatic processes, some more actively than others. The uptake of B vitamins depends on gastric acid and digestion.
