In Depth Protocol

  • The Brain's Building Block: DHA (Docosahexaenoic acid) is the main building block of the Omega-3 family and is critical for neuron formation, brain health, and cardiovascular function.
  • IQ & Brain Health: DHA makes up 90% of the Omega-3s in your brain. You cannot build neurons without it. Research confirms high levels prevent hippocampal shrinkage and improve fluid intelligence and reaction time.
  • Cardio & Mortality: The "Omega-3 Index" is a better predictor of death than cholesterol levels. Moving from an index of <4% to >8% lowers Cardiovascular Disease risk by ~30% and significantly reduces All-Cause Mortality.
  • The Dose (2g+): To reach that protective >8% index, you need 2g–4g of DHA daily. Plant sources like flax or chia convert at a rate of <5% and are insufficient to reach these clinical targets.

✅ Pros

  • Fluid Intelligence:DHA improves working memory and reaction time even in healthy young adults.
  • Mortality Defense: The single most effective nutritional lever for reducing all-cause mortality risk

⚠️ Cons

  • Cost: Getting 2g of high-quality DHA daily requires expensive supplements or eating fatty fish 4x a week
  • Calories: Fats have 9 calories/gram. It's not much but not nothinng to take 6g daily...
