Tag: Vitamin b12 intolerance

Approximately 1-2% of the population has a confirmed vitamin B12 deficiency, but others may need to avoid it due to genetic mutations or allergies. For these individuals, finding a multivitamin that does not have B12 is essential for their health and well-being.

While excessive doses, especially in supplement form, can sometimes cause mild digestive issues like nausea, bloating, or diarrhea in some people, most individuals tolerate recommended doses of B12 well. The answer to "is B12 hard on your stomach" depends on several factors, including the dosage, the form of the supplement, and underlying health conditions.
