I take a cheap men's Daily Vitamin with: Amount per serving: % Daily Value: Vitamin B6 3 mg 150% Vitamin B12 18 mcg 300% which seems about typical for daily vitamins. The article states that: The U.S. Recommended Dietary Allowance for B6 is 1.7 milligrams per day, and for B12 it’s 2.4 micrograms. and that chances of cancer were found to be higher in men taking much higher doses: Lung-cancer risk among men who took 20 milligrams of B6 daily for years was twice that of men who didn’t. Among people who smoke, the effect appeared to be synergistic, with B6 usage increasing risk threefold. The risk was even worse among smokers taking B12. Using more than 55 micrograms daily appeared to almost quadruple lung-cancer risk.
