The Top Protein Powder for Bariatric Patients - And Recipes To Use It!

Following bariatric surgery, you need lots of protein for your body to heal and maintain muscle mass. Unfortunately, with reduced portion sizes, it can be difficult to get your necessary protein intake from food alone. That’s why it’s important to take protein powder for bariatric patients. 

If you’ve started your liquid diet, you may have already begun consuming protein powder for bariatric patients. But is the protein you’re taking the best protein powder for bariatric patients? And are you already bored to tears with the same flavor of protein shakes?

We’re here to help. In this article, we’ll go over the best type of protein powder to take after bariatric surgery (and why). Then, we’ll give you eight tasty recipes to use it in.

So what IS the best protein for bariatric patients? In our opinion, it’s hydrolyzed collagen - and here’s why.

Why collagen is the best protein powder for bariatric patients

Hydrolyzed collagen is the top protein powder for bariatric patients for a number of reasons. Here are just a few of them:

Collagen is hypoallergenic

Collagen protein is hypoallergenic. That means you won’t need to worry about having an allergic reaction to it - which is great news, because no one wants to deal with that post-surgery! 

Collagen protein is something your body produces naturally, so as long as you’re getting your collagen protein powder for bariatric patients from a reputable source, you shouldn’t have to worry about side effects. 

Collagen is easier to digest

Collagen protein powder for bariatric patients is easier to digest than other powders like whey protein. That's because molecules in collagen are much smaller, and thus, more easily absorbed by your body. 

That can make collagen a great option if you are looking for protein powder for bariatric patients but have a sensitive stomach to begin with. 

And, as we mentioned above, you should really be looking for hydrolyzed collagen. This is collagen that has gone through the process of hydrolysis to break the molecules down into even smaller pieces.

Hydrolyzed collagen is even easier for your body to digest and absorb than other forms of collagen.

Collagen can improve gut health

If you are stuffing from gut issues that go beyond your surgical recovery, you’re in luck! 

Collagen protein powder for bariatric patients could be your saving grace. It’s packed full of amino acids that are essential for healing and regeneration of cells in your gut lining. It has even been shown to help with leaky gut syndrome, IBS, GERD, Ulcerative Colitis, and Crohn's disease!


Collagen helps build up a strong digestive barrier which is essential for protecting your gut from potentially harmful microbes and toxins that can cause inflammation. It also improves the absorption of vital nutrients while promoting digestion and nutrient assimilation.

Collagen protein powder for bariatric patients is also known for its anti-inflammatory properties which can help reduce inflammation in the gut and soothe your intestines.

These are all extremely beneficial in a protein powder for bariatric patients, regardless of your usual gut health. You can even begin taking it before your bariatric surgery as part of your pre-bariatric surgery diet to give your gut a little extra help easing through the surgery. 

Collagen doesn’t contain any lactose

If you’re looking for the best protein powder for bariatric patients, it’s important to take lactose into consideration. That’s because many bariatric patients find themselves lactose intolerant after surgery, even if they weren’t beforehand.

If you are lactose intolerant, you can’t digest the sugar (called lactose) that is found in milk. That means you really need your protein powder for bariatric patients to be lactose-free. And guess what whey protein has in it? That’s right, LACTOSE.

Whey protein is actually derived from dairy products, and is full of difficult-to-digest lactose. 

If you decide to go with a whey protein supplement, and your bariatric surgery has made you lactose intolerant, you could find yourself suffering from bloating, gas, stomach cramps, and diarrhea - which would be unpleasant on the best of days, and even worse post-surgery! 

Collagen, on the other hand, contains no lactose at all, which makes it an ideal choice for those who have undergone bariatric surgery.

Collagen protein powder for bariatric patients is a safe addition to any bariatric liquid diet. It’s also an excellent source of protein — in fact, collagen provides more protein than most other sources! This makes it especially useful for individuals trying to reach their post-surgery goals.

Collagen is necessary for healing 

Did you know that your body uses collagen to heal itself? Collagen is actually instrumental to the main stages of wound healing, and collagen fibers are what your body uses to knit itself together after surgery.

So, if you give your body plenty of collagen post-surgery, you will be providing it with stores of the exact thing it needs to heal. That means you may even be able to heal faster after surgery, and who wouldn’t want that!? 

Collagen protein powder for bariatric patients may help you speed through your recovery and hit your healing benchmarks in record time. 

With so many benefits of collagen, it’s no wonder it’s the top protein powder for bariatric patients. And, now that you know, it’s time to experiment with some fun - and bariatric-safe - recipes to enjoy it in!

Tips for choosing your collagen supplement 

When it comes to choosing your collagen protein powder for bariatric patients, make sure you look for a supplement from a reputable company. Your supplement shouldn’t contain any additives or sugar, and needs to be hydrolyzed for easy absorption.

You should also ensure that your collagen supplement has tryptophan added in to make it a complete protein. This will make it much easier for your body to utilize. 

Bear in mind that most supplements aren’t regulated by the FDA, so you have to be your own advocate for your health. If you want to ensure you are getting a safe and healing supplement, you might want to purchase a medical-grade collagen supplement, which IS FDA regulated. 

Use protein powder as part of a holistic health program

Collagen protein powder for bariatric patients and bariatric protein shots are extremely beneficial after bariatric surgery, but they aren’t the last word in weight loss or nutrition.

Following bariatric surgery, it’s important to make some lifestyle changes to help support your weight loss journey. 

First, remember to take it easy on yourself. Your body will be a little delicate for a while, so get plenty of rest until you feel your energy levels come back.

Once you’re back on your feet, you’ll want to incorporate some kind of exercise into your life. You will also want to pay attention to portion sizes, as well as what you’re eating. Eating too much, or getting poor nutrition, can cause health issues or stretch your stomach and undo all your hard work!

With the proper lifestyle changes, and the right collagen supplement, you’ll be well on your way to a healthy new you.
