Choosing the Best Protein Powder for Your Needs

When selecting a bariatric protein powder, consider your own preferences and needs to find the best match. Here are some factors to think about:

Flavored or Unflavored

If you enjoy rich chocolate, vanilla or other sweet shakes, go for a flavored protein. But if you prefer adding your own flavors or sweeteners, an unflavored or lightly flavored option may work better. Also consider mixing flavors, Chocolate Hazelnut and Banana mixed, or Strawberry and Vanilla are great combinations.

Allergy Restrictions

If you have lactose intolerance, a whey concentrate powder may cause discomfort, so a lactose-free whey isolate may be better. For nut allergies, check labels for traces of nuts.


Some protein powders fully dissolve while others retain a grainy or chalky texture. If texture is important, consider mixability. Tip: Chilling overnight helps break down particles.

Portion Control

For precise tracking, choose single-serve stick packs. But for more flexibility in recipes, a tub allows measuring spoon portions.

Budget Friendly

To save money, compare cost per serving. Buying in bulk or subscribing can reduce the prices on some powders. Prioritize higher protein per serving to stretch your dollar further.

Tips for Using Protein Powder After Bariatric Surgery:

Using protein shakes and powders can take some adjustment after bariatric surgery. Here are some tips:

Start Slowly

When first introducing protein powders, have a small amount to check tolerance. Too much too soon may cause temporary nausea or discomfort.

Follow Mixing Directions

Mix the recommended scoop size or stick pack with the suggested water or milk amount for ideal texture and taste. Adding too much or too little liquid impacts results.

Use a Blender Bottle

A blender ball bottle thoroughly mixes the powder into drinks with no clumping or grit. Make sure to tightly secure the lid before shaking.

Chill Overnight

Letting mixed protein shakes chill in the refrigerator overnight allows time for the ingredients to fully incorporate so the texture is smooth.

Boost Flavors

Once comfortable with tolerating powders, try adding peanut butter powder, sugar free syrups, cinnamon or other flavors to create variety.

Divide Daily Protein Intake

Split up your daily protein goal into smaller portions from solid foods and protein shakes to prevent overload from one large serving.

Frequently Asked Questions

Won’t too much protein hurt my kidneys?

For most patients, high protein intake is safe for healthy kidneys. But if you have existing kidney issues, check with your bariatric dietitian or doctor about ideal protein goals. They may recommend a lower daily target.

When can I start using protein powder after surgery?

Your doctor or dietitian will advise when to introduce protein powders, which is usually a few weeks after surgery when your stomach has had time to heal and you can tolerate shakes without discomfort. Introduce gradually.

How much protein powder should I have per day?

To meet the 70-100g daily protein goal after bariatric surgery, aim for 30-50g of your total to come from protein shakes or powders split into a few servings. This reaches goals without overdoing it.

Can I use protein bars instead?

Bars are harder to digest and tolerate initially after surgery. Stick with easy to digest drinks and powders first. After healing, when you can tolerate some soft solid foods, then try incorporating bariatric protein bars if you wish.
