Frequently Asked Questions

This deficiency is relatively common among vegetarians, as Vitamin B12 is primarily found in animal products like meat, fish, and poultry. Additionally, Vitamin B12 deficiency may occur in individuals with certain intestinal diseases such as Irritable Bowel Syndrome (IBS) or those with an Intrinsic Factor deficiency, which is a type of stomach defect that affects absorption.
