So, should the average exerciser be taking collagen supplements? “If you’re young, fit and healthy and your connective tissues are working as they should, it’s not harmful,” says Clarke. However, if you already strengthen your muscles and joints by strength training a few times a week and eat a diet rich in protein, “it can just be a waste of money,” she says.

Even for those who are finding that they are experiencing joint pain, Clarke doesn’t suggest relying on supplements to help. “I always recommend that people should get their intake of any nutrient from whole foods,” she says. “As collagen is a protein, you can get it from eating meat, fish and eggs. Vegetarians and vegans may struggle a little more to get their requirements, but you can get plant-based supplements of collagen if necessary.”

As with everything, joint pain or muscle weakness should be discussed with a practitioner before trying to add supplements into your lifestyle. “It makes sense that these supplements are being targeted to those looking to boost their performance and strength, but the clever marketing may not be true,” says Clarke.
