What Is Protein?

Protein is one of the main macronutrients the body needs for building and maintaining tissues. It is made of amino acids, which are used to support muscle, skin, hair, enzymes, hormones and immune function. Protein is found in many foods, including meat, fish, eggs, dairy products, legumes, soy, nuts and seeds. In sports nutrition, protein supplements (such as whey, casein and plant-based proteins) are popular because they offer a convenient way to increase daily protein intake, especially for active people and those with higher needs.

Benefits of Protein Supplements

Protein contributes to the growth and maintenance of muscle mass and supports normal bone maintenance when combined with a balanced diet and resistance training. Protein supplements are commonly used to support workout recovery, muscle building and daily satiety, which can be helpful during weight-management plans. Many people use protein shakes for convenience when they don’t have time for a full meal or when their diet is low in high-quality protein. Protein can also be useful for older adults who want to maintain muscle mass as part of healthy aging.

Uses of Protein

Protein powders are typically mixed with water, milk or plant milk and used after workouts or between meals to help meet daily protein targets. Whey protein is popular for fast digestion, while casein is slower-digesting and often used in the evening. Plant-based proteins (such as pea, rice or blended proteins) are common choices for vegans and people with dairy intolerance. Protein bars and ready-to-drink shakes offer additional convenient options. On our category page you can explore different protein products – from whey isolates to vegan blends – and choose the option that fits your lifestyle and goals.

Protein: Side Effects and Safety

Protein supplements are generally safe for healthy adults when used as directed, but some people may experience digestive discomfort, especially with lactose-containing products. People with lactose intolerance may prefer whey isolate or plant proteins. Very high protein intake may not be suitable for individuals with kidney disease or certain medical conditions, so medical advice is recommended in those cases. Always follow label directions and choose products with quality testing and transparent ingredient lists.
