Why does my mix foam?

Q Why does my mix foam?

A Foaming is typically caused by the protein in your formula. 

Protein, by its nature, tends to foam when agitated. This is why we do not recommend including protein in Custom Hydration mixes designed for running or high intensity training.

If you have protein in an endurance mix, you will most likely notice some foaming after mixing. But after it gets a chance to sit for a little bit, the foaming should dissipate and you’ll be good to go.
