The Best Vitamins to Take After Bariatric Surgery

Vitamins and Nutrients After Bariatric Surgery

Would love your thoughts, please comment at the end of the post!

There isn’t one vitamin that contains everything you need after bariatric surgery. Our US-registered bariatric nutritionist typically recommends a bariatric-specific vitamin as that will meet most of your requirements.

You’ll also likely need an additional B12 supplement and Calcium + Vitamin D. Some people will require extra iron supplementation as well.

Nutritional Supplements After Weight Loss Surgery – Dosage

Here are the recommendations:

  • Thiamin (B1): at least 12mg, preferably 50mg from a B-complex supplement

  • Calcium: 1200-1500 mg/day in divided doses of 300-500mg (if calcium carbonate, take with meals and if calcium citrate, take with or without meals)
