is 2500 mcg of vitamin b12 to much for one day for a 17 year old?

Waste of money: B12 in excess quantities is rapidly excreted by the kidney. While this much daily probably won't hurt you, it won't help much at all. The typical daily dose for replacement of deficiency is 500mcg. Thanks for trusting HealthTap!
