Too Much Vitamin B
Although most B vitamins are eliminated in the urine, if taken in excess some can present problems. For example, high doses of niacin (vitamin B3) – more than 2-3 grams per day – is sometimes used to help lower cholesterol, yet can cause nausea, jaundice, and elevated liver enzymes. These typically disappear once niacin is discontinued. Too much pyridoxine (vitamin B6) can be toxic, resulting in numbness, tingling, and even nerve damage. The current recommended maximum daily intake for B6 is 100 mg. Findings from a recent study suggest that men who take high does of vitamin B6 or vitamin B12 may be at increased risk of lung cancer, especially those who smoke. Is it possible to take too much vitamin B12? B Vitamins In Supplements
If you choose to supplement, there is no reason not to take the whole complex of eight B vitamins in supplement form, but also no reason to take them apart from a daily multivitamin / multimineral supplement. Multivitamins commonly contain the full spectrum of B vitamins. There are also instances where taking additional individual B vitamin may be appropriate.
