Although present in many foods, the B-group vitamins are delicate and easily destroyed, particularly by alcohol and cooking (B vitamins tend to leak into cooking water). Food processing also removes the B vitamins, making white flours, breads and rice less nutritious than their wholemeal counterparts.
The body cannot store most of the B-group vitamins (except B12 and folate, which are stored in the liver). They need to be consumed every day.
Vitamin B1 (thiamine)There is a danger of a toxic effect being caused by massive doses (e.g. 2 g), and intravenous administration may cause shock.
High doses of vitamin B6 can cause nerve damage, although there is currently some debate at to how much constitutes a dangerous dose. High doses (50-100 mg a day) are said to be helpful in pre-menstrual syndrome but women are best advised to stick to the dose recommended by their pharmacist.
Folic acid (folate) is generally considered non-toxic, although excessive intakes above 1,000mg per day over a period of time can lead to malaise, irritability and intestinal dysfunction
The B complex Numerous experiments have given divergent results which may be ascribed to the differences in the nutritional status of the person concerned. Nearly all authors advocate a moderate intake during muscular exercise with a view to alleviating certain inapparent deficiencies.

I suppose anything in excess can cause problems. The vitamins in the B complex are water soluble, thus anything the body can't use is excreted by the kidneys. So taking more than necessary just makes expensive urine.
Don't push excess vitamins. In spite of all the health nuts out there, follow the axiom, "If a little is good, more ain't necessarily better."

Anything in excess is dangerous, but your body will rid you fo alot of it. Notice that your urine turns dayglow when you take the B? That is because your body is ridding you of the excess vitamins.

You should not take anything which you are not deficient in. You should always see your doctor for blood work to see if you need it first.
