About this listen

 As you age, do you want to stay strong and maintain muscle? Keep your mind sharp and feel full of energy? To look great and feel full of life? I think we all want these. And the good news is, there are lots of things we can do to slow the effects of aging? The food we eat, when we eat, how much we move and the type of exercise we do, the supplements we take and a whole range of other lifestyle interventions can have a huge impact on how our bodies age. I research these things carefully, cutting through the marketing hype where necessary, and I share my findings right here on Quest For Longevity. And I hope that it will help you to make informed lifestyle choices and take better care of your health. If you like the sound of this, why don't you join me on my quest for longevity, and together we'll learn how to live a long and healthy life.2025 Hygiene & Healthy Living

  • Collagen: What Does It Do & Are Supplements Worth The Money?

    Collagen: What Does It Do & Are Supplements Worth The Money?
    Nov 26 2025
    Do collagen supplements live up to the hype? This evidence-based episode cuts through the marketing claims to reveal what science really says about collagen supplements. We explore what collagen is, how it works in your body, and examine the latest clinical trials and meta-analyses on skin health, joint pain, bone density, and muscle function. Perfect for anyone considering collagen or wanting to understand the science behind this billion-dollar industry. Quality Health Supplements I use WeightWorld supplements. They produce great value, quality products and I've been very pleased with the results. (I am affiliated with WeightWorld and receive a small commission if you buy via my link or use my checkout code. This doesn't cost you any extra and anything I earn helps me to devote more time to researching and producing this podcast.)

  • Autophagy: Your Disease Fighting, Life-Extending Super Power

    Autophagy: Your Disease Fighting, Life-Extending Super Power
    Nov 9 2025

    Autophagy is the body's natural recycling system that cleans out damaged cells and renews them from within. We'll look at how this built-in process helps slow aging, boosts energy, and protects against disease, and how simple habits like fasting, exercise, and quality sleep can help switch it on. No extreme diets or complicated science — just practical ways to support your body's own repair system and live a longer, healthier life.
