The Claim

In obese adults with at least three micronutrient deficiencies, a bariatric-specific multivitamin resulted in a 41.0% rate of complete biochemical correction at four weeks, compared to a 15.9% rate with conventional targeted supplementation, indicating that complete biochemical correction remains unattainable for the majority of this population within four weeks.

In plain English

Among obese adults with three or more micronutrient deficiencies, a specialized multivitamin led to complete correction of nutrient levels in 41% of people after four weeks, while standard supplements achieved complete correction in only 16%. Most people did not achieve full correction within this time.

See the scientific wording

In obese adults with at least three micronutrient deficiencies, a bariatric-specific multivitamin achieved a 41.0% rate of complete biochemical correction at four weeks, compared to 15.9% with conventional targeted supplementation, indicating that even with simplified dosing, complete correction remains unattainable for the majority within this short timeframe.

Why this might work

Obese individuals absorb fewer vitamins and minerals from the gut because their digestive system is less efficient, and their bodies need more of these nutrients to function. Even when they take a daily pill designed for them, the amount they get is not enough to fully fix all their missing nutrients in just four weeks because their bodies are using up what little they absorb faster than it can be replaced.

  1. Study: Effectiveness of a Bariatric-Specific Multivitamin Versus Conventional Targeted Supplementation for Preoperative Micronutrient Deficiency Correction in Bariatric Surgery Candidates: A Multicenter Retrospective Cohort Study

    In obese patients with multiple nutrient deficiencies, a single daily vitamin pill helped more people fix their deficiencies in four weeks than taking many different pills—but even then, most still had some deficiencies left. So yes, even with a simpler plan, most people still weren’t fully fixed by surgery time.
