Bariatric surgery is a weight loss procedure that works by limiting the amount of food the stomach can hold, causing malabsorption of nutrients or a combination of both. While these procedures will cause the weight to be lost, they are not a cure for obesity. In order for the weight loss to be successful over the long-term, a patient will need to follow diet guidelines, as well as adhere to lifestyle changes.

One of the postoperative requirements is daily vitamins. Below are some of the most important vitamins for long-term weight loss success after a bariatric weight loss procedure.


Following bariatric surgery, you will need to take a multivitamin for the rest of your life. This multivitamin should include iron, folic acid, selenium, copper and zinc. In the months directly following the surgery, these multivitamins will be chewable.


The daily calcium intake post-bariatric surgery will help to prevent bone disease and calcium deficiency. In some cases, the calcium doses will need to be spread throughout the day to enhance the absorption. The daily calcium intake will need to be between 1,200 and 2,000 mg, so breaking this into 500 or 600 mg doses can be helpful.

Vitamin D

The recommended daily dosage of Vitamin D for post-bariatric surgery patients is 800 to 1,000 international units. This should be split into two daily doses and should be taken with the calcium daily. You may also substitute a calcium-vitamin D supplement to avoid multiple pills everyday.

Iron and Folic Acid

Your dietitian may also recommend additional iron and folic acid supplements. For females that are still menstruating, it is particularly popular for a dietitian to suggest this additional vitamin intake.

Vitamin B12

One very common deficiency following bariatric surgery is vitamin B12. For this reason, it is recommended to have a B12 injection every other month following bariatric surgery to ensure adequate vitamin levels.

The goal of the daily vitamins is to prevent nutrient deficiencies. While bariatric surgery will cause weight loss, sticking to the postoperative regiment suggested by your dietitian is the best way to ensure the weight stays off.
