Vitamin b12 or vitamin b complex, what is the difference?
A doctor has provided 1 answer
Good question: B12 is typically given under the tongue (pill or liquid) or by shot. Although there is some B12 in b complex pills chances our its not enough or can't be properly absorbed by the last 5 inches of your small intestine. (B12 absorbtion requires first binding to intrinsic factor made in the stomach ) either the stomach is dammaged or the small intestine has a problems. B complex varies in content.
