Protein is essential for our bodies to work properly. It plays an important role in building and repairing tissues, making enzymes and hormones that regulate metabolism, and supporting the immune system, just to name a few.
When it comes to muscle, dietary protein is key to ensuring your body has the necessary building blocks (amino acids) to maintain and build lean body mass. Without a surplus of available amino acids, muscles will not grow in strength or size.
While most people can meet their dietary protein needs with a well-balanced diet that includes plant-based and animal proteins, protein powders are often a cost-effective, convenient way to incorporate more protein into your diet.
One of the most popular is whey protein powder, which generally costs around $10–15/pound and has a long shelf life.
