Is It Possible To Overdose On Vitamin B12

Vitamin B12 is a water-soluble vitamin, so it is generally considered safe, even if you take high doses of it.

There is currently no Tolerable Upper Intake Level for B12 because it is not highly toxic. UL refers to the highest daily dose of a vitamin that you can take that will not likely cause any negative side effects for most people.

There is no UL because any excess vitamin B12 that your body does not use gets flushed out in your urine.

However, if you supplement with excessive amounts of vitamin B12 , you may experience some negative side effects.

A number of studies show that megadoses especially from vitamin B12 injections can cause outbreaks of acne and rosacea. Rosacea is a skin condition that forms red patches on your face.

Some evidence implies that very high doses of vitamin B12 can cause complications if you have diabetes or kidney disease. For example, a study from 2010 found that participants who have diabetic neuropathy had a quicker decline in the functioning of their kidneys when they took high-dose supplements of vitamin B12. The people who took the high doses of vitamin B12 were more at risk for heart attack, stroke, and death than the participants who took a placebo, but more research is needed to support this claim. The participants in this particular study took a dose of 1 milligram of oral vitamin B12 supplements each day.
