Protein supplements are products designed to help people increase their protein intake. They come in various forms, such as powders, bars, and shakes, and are often made from sources like whey, casein, or plant-based proteins. Many athletes and fitness enthusiasts use these supplements to support muscle growth, recovery, and overall health. These supplements can be convenient for those who struggle to get enough protein from their regular diet. For example, busy individuals might find it easier to grab a protein bar or mix a protein shake rather than prepare a high-protein meal. However, it's essential to balance supplements with whole foods for optimal nutrition.
