Vitamin B

There are eight B vitamins; thiamine, ribovlavin, niacin, pantothenic acid, pyridoxine, biotin, folic acid, and cobalamine. Each functions as an enzymatic cofactor or is a precursor to an enzymatic cofactor enabling many of the basic functions of metabolism in the body.

Can You Take Too Much Vitamin B?

Vitamins are required for life. A minimum daily dose of each vitamin is necessary to maintain good health. Significantly exceeding this dose, however, can cause illness. In general, the symptoms of vitamin toxicity include nausea, gastrointestinal problems like constipation and diarrhea, hair loss, rashes, and nerve damage.
