How do a Person get Dificiency in Vitamins B6 or B12?

Question

When a Person start to take High Vitamins B6 or B12, slowly symtom like weakness in foot or pin and needle feeling in the body appear.

IS this Dificiency?

Answer 1

Vitamin B12 deficiency is caused by either a dietary lack of B12, which is present in meats or second possibility is lack of a substance called intrinsic factor that is necessary for the body to  absorb and use B12. Lack of IF and consequent B12 deficiency is known as pernicious anemia. You can also have B12 deficiency anemia because of inadequate intake through diet. B12 is important for nerve health. I'm not a doctor, but I suspect that taking a lot of B12 and B6 could require your body to need less intrinsic factor. So your body might downregulate its production. It doesn't seem that likely that a person would develop a deficiency from taking too much, but I know that is the case with other diseases and medical conditions caused by steroid use. If artificially introduced testosterone gets injected into the body, the body does make less naturally. This is also why the male testis shrink (because they realize they are not needed because so much testosterone is present. Well, I'm not sure I answered your question, hopefully I told you something interesting. I think my explaination for the B12 deficiency is possible. Didn't all the pro athletes accused of using anabolic steroids use the excuse that they thought they were receiving B12. Wow, thats coincidence. Totally unrelated, just a coincidence that my explanation included both. Take care.
