A customized multivitamin supplement lowers postoperative deficiencies after a Roux-en-Y Gastric Bypass.

Since iron, vitamin B12 and folic acid deficiencies often occur after a Roux-en-Y Gastric Bypass (RYGB), patients are advised to take daily food supplements. Based on literature and pilot studies, FitForMe developed WLS Forte in 2010, a bariatric multivitamin supplement customized to the needs of RYGB patients. In a triple-blind randomized controlled trial, the effectiveness and safety of WLS Forte was evaluated over 12 months.

Customized versus standard supplements

148 patients were included in the study, 74 of which received one capsule of WLS Forte daily. WLS Forte contains high doses of micronutrients, especially vitamin B12 (14000% RDA), iron (500% RDA) and folic acid (300% RDA). 74 patients served as control group, and received one standard multivitamin supplement daily, containing 100% of the RDA. The nutritional status of the patients was measured at the start, at 6 months and 12 months.

Fewer deficiencies with WLS Forte

Over the course of 12 months, folic acid and vitamin B12 levels increased, and iron levels remained stable for patients using WLS Forte, whereas a decrease was seen in sMVS patients. Furthermore, the total number of patients developing an iron or vitamin B12 deficiency was lower in WLS Forte users, compared to sMVS. This shows the effectiveness of WLS Forte in lowering postoperative iron and vitamin B12 deficiencies among RYGB patients.
