B12 deficiency: You should have a vitamin/mineral analysis done first before you begin supplementing as it may be unneccessary and excessive amounts of B12 can effect b6. Best wishes.

No: This is a water soluble vitamin and the body will lose excess by urination. However moderation is an important rule of thumb and there is no reason to take more than 1, 000 units a day even in documented deficiency.

Dr. Ankush Bansal
Internal Medicine 17 years experience
Blood test: A simple blood test ordered by your doctor will check for your iron and B12 levels. Depending on the result and the interpretation (which takes into account your medical history), appropriate treatment with supplementation may be ordered. Other conditions can cause these to be low so your doctor needs to look at your whole picture.

Many: Vitamin B12 is important for many things including nerve function and the making of red blood cells. If you are low on it, therefore, you could have a low blood count or a numb/tingling sensation. Most adults need about 2.4 mcg (micrograms) daily. The main dietary sources are fish/meat, dairy products, and fortified cereals. Link for more info: http://ods.Od.Nih.Gov/factsheets/vitaminb12/.
