How protein should a 40 year old women take in?

A 40-year-old woman should aim for about 46 grams of protein per day, according to the Dietary Guidelines for Americans. However, this amount can vary based on factors such as activity level, muscle mass, and overall health. For those who are more active or looking to maintain or build muscle, a higher intake of 1.2 to 2.0 grams of protein per kilogram of body weight is often recommended. It's best to obtain protein from a variety of sources, including lean meats, dairy, legumes, and nuts.
