Vitamin B12 is an essential nutrient responsible for many bodily functions, including the formation of red blood cells and the proper functioning of the nervous system. However, taking too much B12 supplements can lead to some unwanted side effects.

If you are experiencing symptoms of B12 deficiency or have a condition that impairs nutrient absorption, talk to your doctor about supplementing your B12 intake.
