Vitamin B12 benefits your mood, energy level, memory, heart, skin, hair, digestion, and more. It is essential for addressing adrenal fatigue, multiple metabolic functions, as well as maintaining a healthy nervous and cardiovascular system.
I always like to highlight the role of B12 in regard to the nervous system, because, without it, our nervous system would be shot. Not only does vitamin B12 help maintain the health of nerve cells and neurotransmitter signaling, but it plays a significant role in the synthesis and maintenance of myelin, a protective covering of our nerves. This is why so many people with vitamin B12 deficiencies also suffer from cognitive decline.
Vitamin B12 also works closely with vitamin B9 (folate or folic acid) to help create red blood cells and improve the usability of iron in the body. These two vitamins work together to create S-adenosylmethionine (SAMe), a compound that helps regulate hormones, immune function, and mood (3✓).
