Post-Bariatric Surgery Nutrition: Vitamins
- After surgery, DO NOT start any vitamins until after your one-week post-op visit with your surgeon.
- You may receive samples of a chewable multivitamin prior to surgery.
- You'll need to take a chewable bariatric-specific multivitamin with iron for the rest of your life.
- Your bariatric team can help you choose the best vitamin for you and will take blood work to determine if you need to take additional vitamins or supplements.

*Duodenal Switch patients may need higher levels of fat-soluble vitamins A, D, E, and K to maintain normal lab values, due to the nature of fat malabsorption caused by the procedure
Some notes about calcium:
- Calcium nitrate is the preferred form – look for this when purchasing a generic calcium brand.
- Calcium and iron compete for absorption: allow at least two hours between your calcium and iron-containing supplement for best absorption.
- The body only absorbs 500 mg – 600 mg calcium at a time; take your calcium doses throughout the day for maximum absorption.

Tips
- Your bariatric multivitamins should have been purchased prior to surgery, and you should have already begun taking them pre-surgery.
- Bariatric multivitamins that meet ASMBS guidelines are not found in stores and must be purchased online. Before you buy, price compare – they are often cheaper on the vitamin company's website than through a third party such as Amazon.
- If you have nausea or trouble tolerating vitamins, try taking them with food or after eating. Slow-release iron may be tolerated better.
- Use a phone timer or the Baritastic app to help you remember to take your vitamins.
- Participate in companies' auto-ship option so you always have vitamins stocked.
