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.

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.
