Vitamin B12, or cyanocobalomin, serves an important function for the development of our red blood cells (which carry oxygen to our tissues) and the function of our nervous system. We obtain most of our Vitamin B12 from foods rich in protein, and the highest levels are found in mollusks, clams, liver, beef, and eggs. Also, the vast majority of multivitamins available will contain Vitamin B12.  Deficiency may occur following Gastric Bypass or Sleeve Gastrectomy surgery, and may lead to difficulty with balance or touch sensation, memory loss, fatigue, depression, and other symptoms.  Most importantly, low stores of Vitamin B12 may not produce symptoms until severe damage to our body has occurred.  For this reason, it is very important to follow-up with your scheduled blood work.
