Protein Powders (Protein Powders (various protein isolates and concentrates)) — Uses, Dosage, Side Effects & Safety
Drug class: Nutritional Supplement / Medical Food
Overview
Protein powders are dietary supplements designed to provide a concentrated source of protein, an essential nutrient needed for muscle repair, immune function, and overall health. They are commonly used by athletes, people recovering from illness, older adults, and those with increased protein needs or difficulty meeting protein requirements through diet alone. Protein powders can be derived from various sources, including whey (milk), casein, soy, pea, rice, and egg. They are typically mixed with water, milk, or other beverages and consumed as shakes or smoothies. Protein powders work by supplying amino acids, the building blocks of protein, which help support muscle growth, tissue repair, and metabolic processes. Patients should know that while protein powders can be helpful in certain situations, they are not a substitute for a balanced diet and should be used as directed. Overuse or inappropriate use may lead to side effects or health risks.
