You may want to check out the ASMBS (American bariatric society) guidelines... do some research before you provide inaccurate information. There are many patients that are years out from surgery and very deficient in many vitamins and minerals bc they take this advice. This can be serious.
It’s recommended pts take up to 3000-5000 IUs of vit D3, 500-1000mcgs B12 daily, calcium CITRATE 1200-1500mg daily, and some pts may also need additional iron, not all. Not to mention flinstone vitamins DO NOT CONTAIN: various minerals required for healing the body needs: manganese, selenium, etc.
A MVI should be 200% of the DV for pts as their needs double compared to the what typical person needs. This is why I don’t recommend them. A majority of ppl DO NOT read supplement facts labels, they simply take the recommended dosage without knowing what they SHOULD be taking.
It may be smarter to base your Recs off of professionals rather than your own googling efforts.
