* Vitamin B1 (thiamine)
* Vitamin B2 (riboflavin)
* Vitamin B3 (niacin)
* Vitamin B5 (panthothenic acid)
* Vitamin B6 (pyridoxine, pyridoxamine, pyridoxal and their 5'phosphorylated analogs, and 4'-pyridoxic acid)
* Vitamin B7 (biotin)
* Vitamin B9 (folic acid)
* Vitamin B12 (cobalamin and analogs (methylcobalamin, hydroxocobalamin and cyanocobalamin))

## Benefits[edit]

Vitamin B has been studied for benefits on mortality and cancer. However, according to a meta-analysis, "there was no significant effect on the rate ratios (95% confidence intervals) for overall cancer incidence (1.05 [0.98-1.13]), cancer mortality (1.00 [0.85-1.18]) or all-cause mortality (1.02 [0.97-1.08]) during the whole scheduled treatment period or during the later years of it". [2]
