Whether your goal is building muscle, improving recovery, maintaining a healthy weight, supporting immunity, or ageing well, adequate protein intake plays a central role in overall health.<\/p>\n\n\n\n<p>Despite its popularity among athletes, protein isn&#8217;t just for people who go to the gym. Every cell in your body depends on protein to function properly. Muscles, skin, bones, hormones, enzymes, and even your immune system rely on a steady supply of amino acids\u2014the building blocks of protein.<\/p>\n\n\n\n<p>Today, consumers have access to many different types of protein supplements.
