Vitamin Supplements after Bariatric Surgery

Because you’ll need to eat smaller quantities of food after bariatric surgery, it will be difficult to provide your body with the nutrients it needs through diet alone. To keep your body healthy as you lose weight, you will need to take supplements that help you maintain adequate levels of key vitamins and minerals.

Gastric Bypass and Sleeve Gastrectomy

After gastric bypass and sleeve gastrectomy, you should:

  • Take two calcium citrate tablets (300 mg each) every morning
  • Take a multivitamin at lunch
  • Take two more calcium citrate tablets in the afternoon (at least two hours after multivitamin)

Calcium Citrate

Your supplemental calcium citrate intake should total 1200 mg in two daily doses of 600 mg. Calcium-rich foods like cheese and yogurt can also be included in your diet to provide further assistance in reaching adequate levels of this important nutrient. Be sure that you are taking calcium citrate and not the similar-sounding calcium carbonate. We recommend Bariatric Best Calcium Citrate with Vitamin D.

Multivitamins

Your multivitamin will provide many other important nutrients that may be lacking in your diet. Be sure to avoid chewable children’s multivitamins, as these will not provide the nutritional value you need. Patients of sleeve gastrectomy and gastric bypass can use any supplement designed specifically for bariatric patients, but we recommend the Bariatric Best Multivitamin.

Duodenal Switch

Because patients of duodenal switch have different nutritional needs, Dr. Stewart will provide you with a supplement formulated specifically for DS surgery. This supplement is not like anything available over the counter and is designed to help you avoid nutritional deficiencies after duodenal switch. These will need to be taken once in the morning and again in the evening.

Duodenal switch patients will also need to take 600 mg of calcium citrate each morning and evening for a 1200 mg daily total. Calcium citrate should not be taken at the same time as your multivitamin, as this can interfere with your body’s absorption of iron and calcium. Wait two to three hours between taking your calcium supplement and taking your multivitamin.

Each day, patients of duodenal switch will also need to take:

  • One vitamin A supplement
  • One vitamin D supplement, which can also be provided in a yearly injection at our offices

The following is an example of a good timetable for supplement use after duodenal switch:

  • 7 AM: Multivitamin, vitamin A and vitamin D (unless you received the injection)
  • 10 AM: Two calcium citrate tablets (300 mg each)
  • 1 PM: Multivitamin
  • 4 PM: Two calcium citrate tablets (300 mg each)

Nutritional Deficiencies

Taking supplements at their recommended intervals and values will help you avoid nutritional deficiencies like anemia, which can lead to a variety of uncomfortable symptoms like:

  • Fatigue
  • Dizziness
  • Irritability
  • Brittle nails
  • Cold hands or feet
  • Irregular heartbeat
  • Shortness of breath

If you begin experiencing issues like these, schedule a check-up so that we can assess your nutrient levels and discuss solutions. We will be happy to help you find nutritional supplements that your body can tolerate if you are having problems finding them on your own.
