Nutrition for Cognitive Health: Evidence-Based Basics
TL;DR
Protein, omega-3s, glucose stability, and hydration without supplement disease claims.
Fuel for the brain
The brain consumes significant glucose and requires adequate protein and micronutrients. Large glucose swings from skipped meals can feel like brain fog.
Mediterranean-style patterns associate with better cognitive outcomes in population studies, though individual needs vary.
Supplement caution
Tier C supplements (D3, K2, glycine, etc.) belong in wellness education without treating or preventing disease on public pages.
Pregnenolone and hormone precursors are Rx-adjacent, not casual cognitive boosters.
Integrated planning
Nutrition coaching sits inside metabolic and cognitive pathways with lab feedback loops.
Consult clinicians before major diet changes if you have medical conditions.
