Protein powders are dietary supplements made from various protein sources, such as whey, casein, soy, or pea. They are commonly used by athletes, bodybuilders, and individuals looking to increase their protein intake for muscle recovery, weight management, or overall health. These powders can be mixed with water, milk, or added to smoothies and recipes. They come in various flavors and formulations, making them a convenient option for those who may struggle to meet their protein needs through food alone. However, it's important to choose high-quality products and consult with a healthcare professional if needed.
