## Resource

Dr. Stephanie Venn-Watson, veterinary epidemiologist, public health scientist, and co-founder of Fatty15 (code: BIOHACKINGBRITTANY), shares the latest science on C15:0, an odd-chain saturated fatty acid she describes as the first essential fatty acid to emerge in over 90 years. This conversation explores why C15 may be foundational for cellular resilience, metabolic health, liver health, brain development, and long-term vitality. Stephanie explains how low C15:0 levels may contribute to fragile cells, accelerated aging, and modern health issues, and why this nutrient matters not just for adults, but for pregnancy, breastfeeding, babies, and children. We also talk about food sources like full-fat dairy, cheese, butter, goat and sheep products, why grass-fed matters, how to test your C15:0 levels, and why supplement quality is becoming more important than ever. Join The LongHer Life for women-specific guidance on peptides, hormones, and longevity. WE TALK ABOUT: 00:35 - What C15:0 is and why it's being called the first essential fatty acid in over 90 years 02:55 - How low C15:0 may contribute to fragile cells and accelerated aging 05:55 - The difference between omega-3s and C15:0 for cell flexibility and resilience 07:20 - Why C15:0 matters during pregnancy, breastfeeding, and infant development 11:20 - The "longevity zone" for C15:0 and what higher levels may indicate 15:10 - Why supplement testing and third-party verification matter 18:30 - How C15:0 compares to other longevity molecules like NAD, metformin, and rapamycin 23:35 - Why C15:0 needs to be consumed regularly through food or supplementation 25:00 - Why vegans and dairy-free women may be at higher risk for low C15:0 levels 26:50 - The best food sources of C15:0, including cheese, butter, and grass-fed dairy 3…
