I invented a method to facilitate dissolving of protein powder shakes for an Innocentive contest. It worked pretty well but I did not win so there must be a better method out there.

The idea is that the powder would rather stay with powder than move off into the water - it is hydrophobic to some degree.

I mixed the powder with a small amount of baking soda and a small amount of powdered citric acid. When dry it was just another powder. When wet, the baking soda and citric acid foamed up, breaking up interactions between the particles of protein shake. The foam (containing shake powder particles) then stirred in easily.

Maybe they did not like the additives. You could taste them both in the shake.

It occurs to me that you could achieve the same end by breaking up the protein powder particles with some hydrophilic powder that did not alter the flavor or nutritional value of the shake. I propose you could use dextrin. https://en.wikipedia.org/wiki/Dextrin This is on the market as a laxative (usually in the store next to metamucil and fiber supplements) but it mixes to imperceptibility in drinks - it is soluble fiber. A brand name in the US in Benefiber. Adding this to the powder and mixing well in advance should facilitate dispersal of the protein shake powder without altering flavor or nutritional benefit.

Third idea: alcohol. If your protein powder dissolves in oil it will dissolve in pure ethanol. Dissolve powder in pure grain spirits - Everclear is a brand in the US. Use the smallest amount of alcohol to get the job done. Once dissolved, make your shake with boiling water then let it sit and cool off before you drink it, or leave it overnight in the refrigerator. The ethanol will evaporate as it cools. Or if you are digging a little kick just make the shake cool and drink the ethanol with. If you are about to go exercise ethanol is good low-carb fuel.
