Protein is an essential nutrient that plays a crucial role in building and repairing tissues, producing enzymes and hormones, and maintaining muscle mass. Without adequate protein, the body’s ability to function properly can be compromised. Knowing whether you’re getting enough protein is vital for maintaining overall health and preventing deficiencies.
