How to avoid foam in protein shake.

Why is there foam in my protein shake? 

Protein powder has a tendency to foam when hydrated and mixed, which some people do not like. Here are 3 factors that affect the formation of foam in protein shakes.  


Mixing adds air to the protein, which causes it to denature (change shape). The water-loving parts of the protein stay in the water, and the water-fearing parts stick out in the air. These rearranged proteins then bond with each other, creating a network that traps air bubbles and holds them in place. The result is foam.


Temperature can also affect the formation of foam. Protein shakes mixed with warm liquid, for example, foam more easily than protein shakes mixed with cold liquid. This is because heat increases kinetic energy, which causes proteins to denature more quickly.


Stabilizers like sunflower lecithin and xanthan gum are a third reason why protein shakes foam. Most protein powders contain one or more stabilizers, which are added to improve characteristics like shelf stability and mixability. These food additives also facilitate the formation of foam, an unintended effect that occurs because stabilizers are surfactants, reducing surface tension and making it easier for bubbles to form.

How to make a protein shake without foam.

Foam, whether it is light and airy or frothy and dense, gets in the way. Use the following tricks to get rid of protein shake foam once and for all.

Add fat. 

Even a small amount of fat interferes with the formation of foam. Fats weaken the bonds that hold the air bubbles in place, causing them to collapse more easily. Good sources of fat to add to your protein shake include nut butter, avocado, and coconut oil. 

Mix slowly, use cold liquid. 

If you use a shaker bottle, shake gently. If you have a blender, use the slowest setting. Finally, use cold milk or water, the colder the better.

Avoid food additives. 

Again, most protein powders contain stabilizers, which facilitate the formation of foam. Choosing a protein powder without stabilizers will solve most of your foaming problems. Here are a few of the most common stabilizers used in protein supplements:

acacia gum, carob bean gum, carrageenan, cellulose gum, gellan gum, guar gum, gum arabic, inulin, locust bean gum, soy lecithin, sunflower lecithin, xanthan gum

When it comes to identifying food additives, go with your gut. 😉 As a rule of thumb, they are the ingredients that you cannot pronounce.

Why drink wholesome

First of all, we add coconut to our protein powders to reduce foaming. Coconut is naturally high in healthy fats, known as medium-chain triglycerides (MCT), which stop foam from forming. Second, our protein powders are stabilizer-free. We do not use food additives of any kind, which helps keep foaming to a minimum.

Sick of protein powder foam? Switch to drink wholesome. It does not foam because it is full of healthy fats and additive-free. Order samples to see for yourself.
