Do Supplements Really Work? | Extra Mile

About this episode

Spencer and Oli discuss the effectiveness of supplements and their necessity in modern diets.

Spencer and Oli unpack the confusing world of supplements. Do we really need them, or can we get everything from food? Oli explains the science behind some of the most talked-about supplements, including creatine, vitamin D, omega-3, multivitamins, protein and probiotics, while cutting through the myths, marketing and guesswork. They also explore why modern diets may leave many of us undernourished, how to think about personalisation, and why the best supplement routine starts with understanding what your body actually needs.
