The 5 Best Protein Powders for Hot Drinks (Coffee, Hot Chocolate, and More)

This article is part of the CrossFit BC journal, written by the coaching staff who run our classes in Olympic Village, Vancouver. We publish what we teach on the floor: training decisions, recovery, nutrition, and the honest tradeoffs behind them.

Common questions

Can you put protein powder in hot coffee?

Yes, but choose the right type. Collagen peptides stir into hot coffee with no clumping and no taste. Whey and most plant proteins clump when they hit liquid hotter than about 70 degrees Celsius, so make a paste with a little cool liquid first, then pour the coffee in slowly.

Does heat destroy protein powder?

No. Heat changes the shape and texture of protein, and moderate heat can make it easier to digest. The clumping in a hot drink is a texture issue, not a nutrition problem.

Is collagen a complete protein?

No. Collagen has no tryptophan, one of the nine essential amino acids. Keep complete proteins like whey, dairy, eggs, meat or fish in your day, and treat collagen as an easy extra.

What is the best protein powder for hot chocolate?

Unflavoured collagen peptides let the chocolate lead, and a collagen creamer adds creaminess and a light vanilla note. Whey works too if you temper it first. Check the label for grams of protein and added sugar.

How do you stop whey protein from clumping in hot drinks?

Temper it. Mix the scoop with two or three tablespoons of cool or room-temperature liquid until it forms a smooth paste, then add the hot liquid slowly while stirring.

How do you make protein coffee?

Brew your coffee, then stir in one scoop of collagen peptides. For whey, make a paste with two or three tablespoons of cool liquid first, then pour the hot coffee in slowly while stirring or frothing.

Does protein powder dissolve in coffee?

Collagen peptides dissolve in hot coffee. Whey and most plant proteins do not dissolve well in liquid hotter than about 70 degrees Celsius and will clump unless you temper them with a little cool liquid first.

Are there any allergy flags?

Whey is dairy, so skip it if you have a milk allergy. Marine collagen comes from fish. Check with your doctor if you are unsure.
