Custom vitamins for bariatric patients: do they outperform standard multis?
NCT ID NCT07021170
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether specialized bariatric supplements (Elan Believe, Compass, Supreme) prevent vitamin and mineral deficiencies after weight-loss surgery better than standard over-the-counter multivitamins. Over 600 adults undergoing sleeve gastrectomy, gastric bypass, or one-anastomosis bypass will be followed for 12 months. The goal is to see if tailored formulations improve nutrient levels and patient compliance.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
specialized bariatric multivitamin supplements (Elan Believe, Elan Compass, Elan Supreme)
What this could lead to
If successful, this could show that tailored supplements are more effective than standard multivitamins at preventing nutrient deficiencies after bariatric surgery.
What could go wrong
This is a Phase 4 trial, so the supplements are already on the market. The main risk is that the specialized formulas may not prove significantly better than standard options, or that side effects like gastrointestinal discomfort could affect adherence.
