Vitamin b12

Vitamin b12 is good for you in many ways. It can increase your energy, it provides nervous system support and promotes healthy digestive system. I take vitamin b12 once a month by a shot due to having gastric bypass but when I don't do the shot the pills are my back up. When my levels are done I can tell cause my energy will be lower than it normally is. Can't go wrong with b12. I received this product at a discount in exchange for my honest review.
