If you’re a coffee lover and a fitness enthusiast, you’ve probably wondered: Can I mix protein powder with hot coffee?

Let’s talk about how you can enjoy a delicious, energizing, and protein-packed cup every morning, and how Javvy can help.

Why Mix Protein Powder With Coffee?

Mixing protein powder with coffee, also known as proffee, has become a popular trend for several reasons:

Convenience: Instead of preparing a separate protein shake, you can combine your morning caffeine and protein in one drink.

Muscle Support: Protein helps with muscle recovery, especially after a workout. Combining it with coffee is perfect for a post-morning exercise routine.

Satiety: Protein keeps you feeling full longer, reducing cravings and snacking between meals.

Energy Boost: Coffee wakes you up, and protein sustains that energy throughout the day.

Can Heat Affect Protein Powder?

A common concern is whether hot coffee will damage the protein content of your favorite powder. Most modern protein powders (whey, plant-based, collagen) are heat-stable and won’t lose their nutritional benefits when added to hot liquids.

The main issue is texture: adding protein powder directly to hot coffee can cause clumping or a grainy texture.

What Are the Best Protein Options for Coffee?

Not all protein powders perform the same in coffee. Consider these:

Whey Protein: Smooth texture, easily dissolves. At Javvy, we use premium whey protein in our protein coffee.

Collagen PeptidesCollagen Peptides: Great for skin, hair, and joint health.

Plant-Based Protein: Pea, rice, or hemp protein can work, but may have a slightly gritty texture.

Bonus: Try Javvy's Protein Creamer for an extra boost of protein and flavor

That said, no matter what type of protein you use, there is always a chance that the texture won’t be as silky as you hoped. We recommend relying on our protein coffee, mixing it cold, and then heating it up after mixing for the best results.

Javvy Protein Coffee makes your daily cup do more. Each scoop starts with 100% real Arabica coffee for a smooth, low-acid sip, then adds 10g of premium whey protein, ~80 mg caffeine, and no added sugar for clean, steady energy.

Our protein coffee mixes silky in water or milk (no clumps, no chalk), and comes in craveable flavors like French Vanilla, Mocha, Hazelnut, Iced Cinnamon Roll, and more. With Javvy, there’s something for everyone.

The Bottom Line

Mixing protein powder with hot coffee can result in clumping or a grainy texture. Instead, it’s best to mix your protein powder with a cold liquid, and then heat it up after mixing.

For a perfectly delicious and nutritious cup of protein coffee every time, choose Javvy.
