Your body uses protein to make muscles, skin, organs, and connective tissue, in addition to antibodies, enzymes, hormones, neurotransmitters, and more. Without protein, your body can’t function. The Recommended Dietary Allowance (RDA) for protein is between 1-1.6 grams of protein per kilogram of body weight, depending on your level of daily activity. For the average sedentary man, that’s 56 grams. It’s 46 grams for the average woman. Keep in mind that the RDA is the minimum amount you need to meet basic nutritional requirements that keep your body functioning. Many people who are interested in nourishing strength, preserving muscle mass, and supporting wellness consume more than the RDA.
