What are the Best Vitamins to Take after Obesity Surgery?

Bariatric surgery is a procedure carried out on people who intend to lose weight. This kind of surgery is achieved by reducing the stomach size or by resecting the small intestine to a small pouch. This surgery is the appropriate weight loss option for those with a Body Mass Index (BMI) above 35. Over time, studies have shown that this type of surgery causes significant weight loss, recovery from Diabetes, improvement in cardiovascular risk factors and even a reduction in mortality rate from 40% to 23%.

Although the chances of pre-operative complications are very low, but complications after surgery can be high because obesity surgery often involves the manipulation of gut that alters the natural process of nutrient absorption, which may result in nutritional deficiencies. However, regular consumption of right vitamins and supplements can help you to avoid this complication.

What are the Best Vitamins and Supplements to take post-Bariatric Surgery?

According to CER Bariatrics, one of the leading bariatric surgery centers within the chain of CER Hospitals in Ti9juana, Mexico, you must take the following vitamins and supplements on a daily basis to prevent
nutrient deficiencies.


Take a high-potency, chewable multivitamin, and mineral supplement, containing a minimum of 18 mg of iron, 400 mcg of folic acid. It must also contain selenium, copper, and zinc.

Brands that contain this formula include Trader Joe's and Centrum adult chewable multivitamins. Take two tablets daily until at least three months after your surgery, and then one tablet daily for life.


Take 1,200 to 2,000 mg daily to prevent calcium deficiency and bone disease. To
enhance absorption, take the calcium supplement as two to three divided doses
throughout the day. For example, take 500 to 600 mg tablets three times a day.
Calcium citrate is the preferred form of calcium.

Vitamin D

Take 800 to 1,000 international units (IUs) of vitamin D daily. This total amount
should be taken as 400 to 500 international units (IUs) twice a day with your calcium supplement. If you prefer, you can take a combination of calcium-vitamin D supplement as long as it contains the proper dosages to avoid taking multiple pills.

Vitamin B12

Take 500-1,000 mcg of vitamin B daily. This can be taken as a tablet or a tablet or liquid under the tongue. Remember, whole pills must be crushed.
You may need additional folic acid or iron supplements, particularly if you are a
female and still menstruating. 

Biotin (Optional)

Take 10,000mcg of Biotin daily for stronger nails, and the health of skin and hair. Depending on blood work test results done three months after Bariatric surgery, you may be required to add additional vitamins and nutrients to your diet plan per your PCP's instructions.
