Are Supplements a Scam? Dietician Josie Porter on What Actually Works

This week, I’m joined by dietician and author Josie Porter, who has written a brilliantly myth‑busting book called How Not to Take Supplements. If you’ve ever stared at an Instagram ad for collagen, creatine or a very chic greens powder and thought “Do I really need this?”, this episode is for you. We talk about why the supplements industry is booming, how clever marketing and “natural” branding manipulate our fears, and why more pills do not automatically mean better health. Josie explains what third‑party testing actually is, the red‑flag claims to avoid, and when supplements like vitamin D, Omega-3 or creatine might genuinely help. We also get into cheaper, easier food swaps that can replace a lot of pricey bottles, the power of good old tap water, and why a decent poo is still one of life’s greatest joys.​ If you’ve ever felt overwhelmed by wellness noise, I promise this conversation will leave you feeling calmer, clearer and a lot less confused.

BOOKS DISCUSSED IN THIS EPISODE

Josie’s book, How Not to Take Supplements, is available to pre-order now and will be released on 4th June 2026.
