Vitamin B-12 supplements can help to remedy a variety of health ailments without our resorting to expensive drugs that might present side effects. B-12 is said to be good for heart health, increased energy, and mental functions though none of these claims have been substantially verified.
Vitamin B-12 is one of the water soluble vitamins and is particularly needed for blood components and in proper nerve function. B-12 also plays a role in DNA synthesis and fatty acid metabolism.
Natural B-12 Sources: Vitamin B-12 is found in milk and dairy products. Many cereals are fortified with B-12, and cold water fish are also a good source of this vitamin.
I read somewhere that the Vitamin B12 molecule is too large to penetrate the skin. Does anyone know of a website that lists molecule sizes (I haven't been able to find one) of various things (obviously including Vit B12) and what will or will not be absorbed by the skin? I've been using DMSO with B12 in it and would like to know if I'm wasting my time by using it this way. Thanks so very much!
