4 Essential Bariatric Vitamins and Supplements for Post-Surgery Patients



Ideally, you get all the vitamins and nutrients your body needs from food. But for weight loss surgery patients, this isn’t always the reality.

After your weight loss surgery, your doctor will likely put you on a liquid diet for several days before reintroducing solid foods to your body. Your food options are limited during this time, which means you may need to take a supplement to fuel your body.  

Take a look at four essential bariatric vitamins and supplements for post-surgery patients to help you on your road to recovery:


Complete Multivitamins

One of the core purposes of bariatric surgery is to cut back on how much you eat. But eating less food also means reducing the nutrients you take in each day. 

You can mitigate this risk by taking a multivitamin that ensures your body gets the right balance of vitamins and minerals, regardless of what you eat. However, keep in mind that vitamins shouldn’t be a replacement for eating well. They’re simply there to fill any nutritional gaps left behind when you reduce your caloric intake.



Calcium is an essential nutrient for healthy bones, nerves, and muscles. Taking a calcium citrate or calcium carbonate supplement can help you prevent damage to your bones and muscles and promote healthy nerve function.



Iron is an essential mineral in hemoglobin, which transports oxygen to vital tissues. Since most dietary iron comes from solid foods like meat, bread, and vegetables, you may need to take an iron supplement while you’re on your post-surgery liquid diet.

Iron should only be taken as a supplement when there is a deficiency. Talk to your doctor to see if he or she recommends an iron supplement, and how often or how long you need to take it.


B Vitamin Blend

B vitamins affect a range of areas, from mental clarity to immune system functionality to improving energy levels and more. Some bariatric procedures make it difficult for the stomach to release B vitamins during the digestive phase (particularly B12), so your doctor may recommend a supplement.



As with any supplement, it’s important to talk to your doctor. Some supplements may interact with medication or other health conditions.

Stock up on vitamins and supplements and prepare for life after weight loss surgery.
