Protein-fortified smoothies and shakes are blended beverages designed to boost protein intake, typically combining a liquid base (like milk or plant-based milk) with protein-rich ingredients such as whey, casein, soy, or pea protein powder, often along with fruits, vegetables, and other add-ins. They are popular worldwide, especially in fitness and health-conscious communities, and originated as convenient post-workout recovery drinks in the United States during the late 20th century.
These drinks are primarily high in protein, with a moderate amount of carbs and fat depending on the recipe, providing essential amino acids for muscle repair and growth. A typical serving can range from 200 to 400 calories, with 20-40 grams of protein, making them a nutrient-dense option for meal supplementation or recovery.
