Bariatric Fusion Vitamin B1 is an easy, affordable, and convenient way for bariatric surgery patients to get vitamin B1, also known as thiamine. With just 1 capsule daily, this formula supports energy production, nervous system function, carbohydrate metabolism, and brain health.*

B complex vitamins, including vitamin B1, are a group of water-soluble vitamins that are typically excreted by the body when consumed in excess and must be replenished daily.

Following weight loss surgery, patients are at a higher risk of micronutrient deficiencies due to nutrient malabsorption and lower nutrient intake with smaller meals. Bariatric multivitamins with B vitamins are recommended after bariatric surgery to help prevent nutrient deficiencies. In some cases, additional vitamin B1 (thiamine) is recommended to support ongoing health.*

Bariatric Fusion Vitamin B1 delivers 100 mg of vitamin B1 (8,333% of the Daily Value). Because bariatric surgery can impact the body’s ability to absorb nutrients, a high supplemental dose of vitamin B1 (thiamin) may be needed to maintain healthy levels. For a similar product containing vitamin B1, try our B-50 Complex.

Bariatric Fusion’s bariatric multivitamins and supportive supplements are formulated by a team of bariatric practitioners to support nutrient absorption for those who have undergone ASMBS-endorsed procedures, including duodenal switch, SIPS, SADI-S, sleeve gastrectomy, gastric bypass surgery, lap band, and intra-gastric balloon.
