Many patients have a hard time getting in the recommended daily amount of calcium. So we combined a bariatric multivitamin with calcium citrate to create a solution. This allows you to eliminate a pill every day in your vitamin protocol. Now all you need to do is add a separate iron supplement of your choice to complete your daily regimen (if needed). We use calcium citrate in our multivitamins with calcium, since it's the recommended form for weight loss patients. Please note that we have not combined calcium and iron in these multivitamins, because calcium and iron compete for absorption and should be taken 2 hours apart.
