5. Maintaining Muscle Tone
Preventing muscle loss as we age is essential in helping maintain an active lifestyle. Vitamin B12 helps in this regard because it plays a key role in protein metabolism. Protein is required for every cell in the body and particularly for muscles. Once the body has broken protein from the diet down into individual amino acids, which are the building blocks of protein, it needs to put them together again, in different combinations, to renew and repair muscles. Ensuring an adequate supply of Vitamin B12 helps the body in making this process possible.
