How Helping Dolphins Turned Into a Life Changing Discovery To Help Humans Age Better with
Dr Stephanie & Dr Eric Venn-Watson

Dr Stephanie Venn-Watson and. husband physician Dr Eric Venn-Watson are one hell of a dynamic duo out to save the planet one person at a time and they started out by helping dolphins live longer. What started as a surprising discovery to protect dolphins' health has become a growing movement to restore our body's C15:0 levels, support our long-term health, and perhaps even slow aging.

The groundbreaking discoveries around C15:0's healthy aging benefits have been featured as a TEDx talk, a Fast Company World Changing Idea, and now––a shout out in The New York Times Science section!

Amazing! Wait - what is C15:0?

Well in this episode we dive into just that very topic.

C15:0 (aka pentadecanoic acid) is a healthy, odd-chain saturated fatty acid naturally found in whole fat dairy, as well as some fish and plants. C15:0 is the first essential fatty acid to be discovered since omega-3, which was over 90 years ago. Because pure C15:0 has been shown to have 3x the cellular benefits of the highest performing omega-3, C15:0 is emerging as the essential, essential fatty acid.

Numerous peer-reviewed studies have shown that people with higher C15:0 levels have better metabolic, heart, immune and liver health. Unfortunately, our C15:0 levels naturally decline as we age.

But I thought fats were bad? 

Society spent a generation avoiding fat.
But what does the science say?

Join us in. this episode to find out why your cells will age slower with Fatty15.

My favourite podcast ⭐ ⭐ ⭐ ⭐ ⭐

Helps me get through my boring desk job. Absolutely love this podcast. Great topics and advice that has helped me to better myself and my approach to running.


Two thumbs up ⭐ ⭐ ⭐ ⭐ ⭐

Always great guests, great insights and learnings that can be applied immediately for every level of experience.


Motivational and Inspirational ⭐ ⭐ ⭐ ⭐ ⭐

I am getting my mojo back with regards to my health and running after treatment for breast cancer, I connected with Lisa as I was looking for positive influences from people who are long distance runners and understand our mindset. Lisa’s podcasts have been a key factor in getting me out of a negative space where I allowed others limiting beliefs to stop me from following my heart and what I believe is right for me. After 18 months of being in cancer recovery mode I wanted to get out of the cancer mindset and back to achieving goals that had been put aside. Listening to Pushing The Limits has put me onto other great podcasts, and in the process I have learnt so much and am on a pathway to a much better place with my mindset and health. Thanks so much Lisa for doing what you do and always being you.
