Do specialized bariatric multivitamins lower deficiencies after RYGB?

Area of Science:

• Bariatric Surgery Outcomes
• Nutritional Science
• Gastroenterology

Background:

• Bariatric surgery, particularly Roux-en-Y gastric bypass, carries a risk of vitamin and mineral deficiencies.
• Common deficiencies include Vitamin B12, Vitamin D, folate, and iron.

Purpose of the Study:

• To evaluate the efficacy of a specialized multivitamin supplement in preventing nutrient deficiencies in Roux-en-Y gastric bypass patients.
• To assess supplement effectiveness over the first three years post-surgery.

Main Methods:

• Retrospective analysis of a large, prospectively collected cohort of 1,160 Roux-en-Y gastric bypass patients.
• Comparison between users (883) and non-users (258) of a specialized multivitamin supplement.
• Analysis of serum concentrations and incidence of deficiencies at 1, 2, and 3 years postoperatively.

Main Results:

• Multivitamin users exhibited higher serum concentrations of ferritin, vitamin B12, folic acid, and vitamin D after one year compared to non-users.
• Significantly fewer new deficiencies in ferritin, vitamin B12, and vitamin D were observed in supplement users.
• These positive effects on nutrient levels and deficiency prevention were sustained at the two and three-year marks.

Conclusions:

• Specialized multivitamin supplementation is effective in reducing deficiencies of vitamin B12, vitamin D, folic acid, and ferritin in Roux-en-Y gastric bypass patients.
• Roux-en-Y gastric bypass patients benefit from specialized multivitamin use.
• Advising specialized multivitamin supplements to this patient group is recommended.
