What is the difference between Vitamin B12 and B Complex?

What is the difference between Vitamin B12 & B complex? Do I need both?? I'm looking at the bottle of my B Complex and it doesn't list B12 but it lists B6. Should I take both a vitamin b12 and b complex every day? I'm a vegetarian woman and heard that Vitamin b12 is good to prevent anemia. I also take iron supplements.

1. yes you can take both but watch the b12 intake and take as directed..b12 if you take to much becomes a poison in the body due to the body cant release it in urine like most vitamin supplements
2. B-Complex contains all of the other B- vitamins. Super B- Complex also contains B12 and C. B-12 is also good for preventing hangovers, along with B-1!
3. B 12 cannot be absorbed properly if taken orally. It must be given by injection and your doctor would have to give the injections.
4. B-Complex is a group of eight B vitamins of which B-12 is one. The 8 B vitamins are: B1, B2, B3, B5, B6, B7, B9 and B12. To correct another answer, B vitamins ARE water soluble and the excess vitamins are passed in the urine (makes it bright yellow) so it is safe to take the B complex and the B-12.
5. (Cobalamine): Vitamin B12 is a water-soluble vitamin needed for normal nerve cell activity, DNA replication, and production of the mood-affecting substance SAMe (S-adenosyl-L-methionine). Vitamin B12 acts with folic acid and vitamin B6 to control homocysteine levels. An excess of homocysteine has been linked to an increased risk of coronary disease, stroke and other diseases such as osteoporosis and Alzheimer’s.

6. Vitamin B12; A vitamin that is needed to make red blood cells and DNA (the genetic material in cells) and to keep nerve cells healthy.
