Episode notes
Omega‑3 Index Predicts Longevity
- The omega-3 index in red blood cells predicts mortality and cardiovascular risk; higher levels (≈8–11%) associate with longer life.
- Many Americans have low indices (~4–5%) that can improve with supplementation.
How Omega‑3s Modulate Brain Function
- Omega‑3s reduce inflammation via resolvins and specialized pro-resolving mediators, aiding serotonin release.
- DHA also alters membrane fluidity, affecting neurotransmitter receptors and brain function.
Check And Dose Vitamin D3
- Measure 25‑OH vitamin D and aim for ~40–60 ng/mL; supplement with D3 (1,000 IU raises ~5 ng/mL).
- Typical correction from 20 to 40 ng/mL may require ~4,000 IU/day.
