There is no credentialed medical research that shows any medical consequences of Vitamin B12 overdose. B12 is a non-toxic substance. The liver stores a 3-5 year supply of B12, and the rest is sent directly to the colon for elimination. You are far more likely to have some kind of reaction to the inactive ingredients in your B12 tablets than you are to the B12 itself.
B12 is a key vitamin in maintaing healthy brain and nervous-system functions, along with being extremely important in the formation of new blood cells. Without enough B12, the body can suffer nervous-system slow downs and possible brain damage, but that occurs in more severe cases. More commonly there is a problem witht he blood. Almost always it is some form of anemia. Generally, it is with easy bruising and slow clotting of blood to an open cut, sore, or wound. In severe cases or deficiences that go on for too long, psychosis and mania can occue along with permant and irreversible brain damage. Small deficineces can cause weakness and fatigue, too.
Vitamin B-12 is vital to moving energy around the body and in healthy brain & nervous system functioning. If you don't get enough B-12, you will tire easily & be fatigued all the time, be depressed, find it hard to concentrate, encounter memory problems, have numb or tingling hands and feet, and other worse symptoms.
