Brain, Mood & Cognitive Performance
Everything Aviado has reviewed on cognitive function, mood, and long-term brain health — organized by evidence tier, biomarker, and sub-theme. Starts with what the primary literature actually supports, not what marketing claims.
Start from a number.
Each biomarker clusters the supplements and articles with measurable impact on that marker. Drill in for ranges, mechanisms, and what the evidence actually moves.
% of EPA+DHA in red-blood-cell membranes. Target ≥ 8% for cognitive protection; most US adults sit at 4–5%.
Amino acid elevated in B-vitamin deficiency. Levels > 11 µmol/L associated with accelerated brain atrophy.
High-sensitivity C-reactive protein. > 3 mg/L associated with chronic systemic inflammation affecting the brain.
3-month average blood glucose. Levels ≥ 5.7% associated with cognitive decline independent of diabetes diagnosis.

Questions Aviado Research hears on this pillar.
What’s the difference between "cognitive support" and "neuroprotection"?
Editorial draft pending — Distinguish acute cognitive performance (attention, working memory) from long-term structural preservation (grey-matter volume, tau, amyloid). Note that the evidence shapes are different — short RCTs vs longitudinal cohorts — so a supplement can sit at different tiers across the two.
How do evidence tiers apply to this pillar specifically?
Editorial draft pending — Restate the 4-tier rubric with brain-pillar examples: Strong = ≥2 concordant RCTs; Moderate = 1 RCT + replicated observational; Preliminary = early human data or single trial; Insufficient = animal/mechanism-only. Keep this short — link to /methodology/ for the full rubric.
What if my biomarkers are already in range?
Editorial draft pending — Inclusive disjunction — for readers who test, explain that insufficiency responds to supplementation more reliably than sufficiency; for readers who don’t test, explain how dietary patterns and life-stage signal whether the gap is likely. Never imply testing is required.
How often is this pillar refreshed?
Editorial draft pending — Quarterly cadence; out-of-band re-reviews triggered by new meta-analyses, regulatory action, or emerging safety signals. Link to /methodology/ for the re-review policy.
