Episode description
In this mind-blowing episode, you'll get to discover how a Navy dolphin program accidentally cracked open an exciting breakthrough in human health and longevity.
I sit down with Dr. Stephanie Venn-Watson, a veterinary epidemiologist whose fascinating path led her from caring for military dolphins to identifying a completely overlooked fatty acid—C15:0—that's now being recognized as the first essential fatty acid discovered in over 90 years.
If you’ve ever been confused about dairy fat, the nuances of saturated fats, or how to truly fuel your body for lasting vitality, this conversation will clear it all up—and give you real, actionable ways to start leveraging this cutting-edge science right away.

Mindsip insights from this episode:
Activate pathways with C15 to mimic exercise benefits
C15 activates pathways like AMPK and PPAR, which are the same pathways triggered by exercise, suggesting it may act as an exercise mimetic.
Incorporate C15, a newly identified essential fatty acid, into your diet
C15 has been identified as the first essential fatty acid to be discovered in over 90 years, a nutrient our bodies need but cannot make enough of.
Differentiate between odd-chain and even-chain saturated fats for health benefits
Odd-chain saturated fats like C15 are beneficial and anti-inflammatory, whereas even-chain saturated fats like C16 and C18 are pro-inflammatory.
Discover high-altitude cheese benefits for longevity
Cheese from grass-fed sheep and goats at high altitudes, like in Sardinia, contains significantly more C15, which may contribute to the population's longevity.
Discover C15 as a natural alternative to rapamycin for longevity
In cellular studies, C15 demonstrated more longevity-enhancing benefits than metformin and rapamycin, with effects that most closely mimicked rapamycin.
Leverage C15 for improved mood and sleep quality
Your body converts C15 into a metabolite that is a full-acting endocannabinoid, which may explain user reports of deeper sleep, calmer mood, and less joint pain.
Test your C15 levels with at-home blood spot test
You can measure your C15 levels with an at-home blood spot test from labs like Genova Diagnostics to see if you are deficient.
Investigate dolphin health to uncover insights on human diseases
The discovery of C15's benefits originated from studying aging Navy dolphins that were developing human-like diseases such as diabetes and Alzheimer's.
