Vitamins and Minerals

You will not be able to maintain vitamin and mineral levels without supplementation. This is due in part to consuming small amounts of food and decreased absorption after surgery. Multivitamins as well as Calcium, Vitamin D and Vitamin B12 are required daily supplements. Some patients may require Iron, Vitamin C and Zinc. Specific vitamin and mineral guidelines can be found in your bariatric diet book. Call our office if you have any questions.

 

Vitamin and Mineral Supplements

You will not be able to meet certain vitamin and mineral needs without supplementation because of the small amounts of food that you will eat and because your body may have difficulty absorbing them. Required daily are multi-vitamins, calcium, vitamin D and vitamin B12. Required for some are iron, vitamin C, and zinc.

All of the required vitamin supplements are available over the counter at your local pharmacy. If you have difficulty locating or tolerating any of the supplements, call your dietitian, nurse practitioner or surgeon for suggestions.

Patients need to be on a chewable form of vitamins for approximately 3-4 months after surgery. Then you can switch to a solid pill form when you are able to tolerate solid foods and have no difficulty with swallowing bigger pills.
