Post-Bariatric Surgery Vitamin Guidelines

Post-Bariatric Surgery Vitamin Guidelines

If you have had bariatric surgery, then it is important to follow the post-surgical vitamin guidelines. This will help ensure that you are getting the proper nutrients and vitamins that your body needs to heal and recover. In this blog post, we will discuss the vitamins to take after bariatric surgery in detail. We will also provide a list of recommended supplements for those who have undergone bariatric surgery.

Long-term health complications of weight-loss surgery can include:

  • Anemia
  • Bone loss
  • Gallstones
  • Hair loss
  • Malnutrition
  • Skin problems such as rashes and dryness

To avoid these complications, it is important to take a multivitamin daily, especially one that contains iron, calcium, and vitamins B12 and D. You should also take a vitamin B12 supplement if you have had gastric bypass surgery. It is also important to eat a healthy diet and get regular exercise. If you have any questions about the post-bariatric surgery vitamin guidelines, then please contact your doctor or nutritionist.

The best vitamins for bariatric patients are as follows:


For the first several months following surgery, multivitamins should be chewable or liquid. Avoid gummy vitamins and vitamin skin patches.

Take an over-the-counter multivitamin in the morning and at night. Several multivitamins are made specifically for bariatric patients.

Not all weight-loss surgery supplements are equal. Certain procedures, like the duodenal switch, need additional daily vitamin supplements. Consult a dietician or bariatrician to ensure you’re getting enough vitamins and minerals.


After sleeve gastrectomy or Roux-en-Y gastric bypass, calcium demands are 1,200–1,500 mg/day. After duodenal switch, you require 1,800–2,400 mg/day calcium. Food contributes to your daily calcium intake. If you eat a lot of calcium, reduce your supplement intake.

500–600 mg of calcium may be absorbed at once. Assist absorption by taking three split dosages throughout the day. Calcium citrate is favored.


3,000 IU or 75 micrograms of vitamin D3 daily. To find out whether you’re getting enough vitamin D, add it to your multivitamin and calcium pills. If not, take a vitamin D3 supplement.


You may sublingually consume or inject this vitamin. Consult your health care provider about the best choice for you.

Oral B12 500 micrograms daily A prescription is needed for monthly B12 injections.

Of course, it’s not just vitamins to worry about; you need to get lots of fiber too. Read about the types of fiber you should eat after bariatric surgery.

Annual Vitamin and Mineral Level Check

Annually check vitamin and mineral levels. Your bariatric team should evaluate this. If that’s not possible, have your primary care physician check your nutritional levels annually.
