Research Decoded

New studies. Same seven questions.

What they studied, what they found, what they didn't, how strong the evidence is, and what — if anything — to do. Every study linked.

Research Decoded

The creatine-and-memory trial

Nutrients, 2026 · n=112 · 12 weeks · randomized, placebo-controlled
What they found
Modest but measurable gains in working memory in older adults on 5 g/day creatine monohydrate.
What they didn't
Small sample, short duration, one cognitive domain. Effects were strongest in those with low dietary creatine.
What to do
If you're over 60 and eat little meat, 3–5 g of monohydrate daily is safe and cheap. Don't expect a transformation; expect a nudge.
Evidence strengthModerate

Research Decoded

The GlyNAC mitochondrial study

Clinical Nutrition, 2026 · n=24 · 16 weeks · randomized
What they found
Glycine plus NAC raised glutathione and improved oxidative stress, inflammation and insulin-resistance markers toward younger values.
What they didn't
Very small trial. Markers, not outcomes. Doses were high (studied under supervision).
What to do
Interesting for anyone with low glutathione or high oxidative stress on labs; talk to a practitioner about dosing rather than copying the study.
Evidence strengthEmerging

Research Decoded

Fermented foods vs high-fiber diet

Cell, 2021 (re-analysis 2026) · n=36 · 10 weeks
What they found
Fermented foods increased microbiome diversity and lowered inflammatory markers; high fiber did not, in this window.
What they didn't
Ten weeks is short for fiber to show benefits; the fermented arm was intensive (six servings a day).
What to do
Add one fermented food a day and work up. Keep the fiber — the two aren't rivals.
Evidence strengthModerate
