Protein helps your muscles to recover and build post-exercise. 16,17 In general, most people
are advised to get roughly 0.8–1g of protein per kilogram of body weight per day.

However, this can vary – your protein requirements depend on all sorts of things, from age
to activity level to overall health. For example, if you’re unwell or recovering from an
operation, your requirements might be closer to 1.5g per kg.19 The more active you are, the
higher your protein requirement is too.20,21
If you’re looking to supplement your protein intake to make sure you’re getting enough,
whey protein is thought to be a great source. This is because research has found that it’s a
complete, high-quality protein with a rich amino acid profile (which means it contains all the
nine
essential amino acids).
22,23 By comparison, most plant-based foods are incomplete
proteins.

In addition, a meta-analysis in 2013 showed its effects in regulating muscle mass and body
composition in resistance training; however, more research is needed.25
However, you should speak to your doctor before adding whey protein to your diet. They’ll
then be able to accurately assess your protein intake needs and offer tailored advice.
