This dietitian resource is a handy ready reckoner for those who work with patients to titrate blood results to an appropriate bariatric multivitamin. It provides a summary of nutrient guidelines (National reference values and American Society for Metabolic and Bariatric Surgery) and the nutrient formulation of several bariatric multivitamins available in Australia. Information for this version was sourced online in February 2025 and it is expected to need updating as product formulations change.
