Callion Pharma is pleased to announce the publication of A Randomized Trial of a Novel Chewable Multivitamin and Mineral Supplement Following Roux-en-Y Gastric Bypass, Perin J, Prokopowicz G, Furtado M, Papas K, Steele KE.

A prototype to DEKAs Bariatric has been studied in a randomized controlled clinical trial against the standard bariatric regimen at The Johns Hopkins Center for Bariatric Surgery.

“At 3 months, plasma levels of PTH were lower (p = 0.042), and levels of vitamin D (p = 0.033), thiamine (p = 0.009), and beta-carotene (p = 0.033) were higher in the investigational multivitamin arm compared to those in the standard regimen arm. Patients receiving the investigational multivitamin reported higher taste satisfaction than those receiving the standard regimen (p = 0.035).”

“The investigational multivitamin appears to be more effective than a standard multivitamin in maintaining therapeutic levels of clinically relevant vitamins and minerals, and was more palatable.”
