Why Kids May Be Aging Faster Than They Should: C15:0, Nutrition Gaps, and Brain Health with Dr. Stephanie Venn-Watson of Fatty15

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.
