What Is Protein Coffee? Benefits, Pros & Cons and Comparisons

Every morning in the USA, millions of people start their day with coffee. According to the National Coffee Association, 63% of Americans drink coffee daily, averaging about three cups per day. At the same time, protein has become the most sought-after nutrient in American diets, with over 50% of consumers actively trying to increase their protein intake, according to the International Food Information Council (IFIC). It’s no surprise these two trends have merged.

So, what is protein coffee, and why has it become one of the fastest-growing functional beverage trends in the United States? Often called “proffee,” protein coffee blends brewed coffee with protein powder or a ready-to-drink protein shake. The result is a beverage that delivers caffeine for energy and protein for satiety and muscle support, appealing to busy professionals, athletes, and health-conscious consumers alike.
