The Importance of Vitamin B After Weight Loss Surgery

What are the B-vitamins?

  • Vitamin B6 (pyridoxine)
  • Folate (folic acid)
  • Vitamin B12 (cobalamin)
  • Vitamin B1 (thiamin)
  • Riboflavin
  • Niacin
  • Pantothenic acid
  • Biotin 

These vitamins work hand in hand to support metabolism and convert the food you consume into energy for the body. B-vitamins are water-soluble and the body will usually excrete what it doesn’t need. Some B-vitamin deficiencies are more common than others after bariatric surgery due to decreased dietary intake and/or malabsorption. 

What is the role of vitamin B12?

  • Important for growth
  • Promotes proper functioning of the nervous system

Why are bariatric patients at higher risk for vitamin B12 deficiency?

This vitamin requires intrinsic factor that is produced by stomach cells in order for the intestines to absorb it properly. Some bariatric surgery options result in surgical changes made to the stomach and/or small intestine. Due to this change, stomach cells are unable to produce adequate amounts of intrinsic factor to bind vitamin B12 for absorption. The ASMBS guidelines for bariatric patients recommends 350mcg - 1000mcg daily depending on your individual needs. There are different forms of supplementation, from nasal sprays to sublingual tablets.
