SPERMIDINE, IN NUMBERS — A Tenth of a Diet: Twenty years of Alpine food records, one famous trial, and the dose question behind spermidine. Whole-grain bread, a halved apple and pear, sprouts and potatoes on an oak table by a window over Alpine meadows.

A Tenth of a Diet: What Twenty Years of Alpine Food Records Linked to Spermidine, and Why the Best-Known Trial Gave So Little

Twenty years of food records from one Alpine town linked spermidine-rich eating to longer survival. Then the best-known supplement trial gave about a tenth of what people already eat. Here...

MENOPAUSE, MEASURED — The Two-Year Window: What a long resveratrol trial measured in women after menopause, and the curcumin pilot that followed. A tall window at dawn with rose-plum light, a grape vine and a turmeric root.

A janela de dois anos: o que um longo ensaio com resveratrol mediu em mulheres após a menopausa (e o estudo-piloto com curcumina que se seguiu)

Num ensaio cruzado de dois anos, 125 mulheres após a menopausa passaram, cada uma, um ano a tomar resveratrol e outro a tomar placebo. Veja o que mudou, quem mais...

PTEROSTILBENE, READ CAREFULLY — The Side Effect They Published: What one careful trial found in the bloodwork, and why the partner compound mattered. Two capped tubes of pale plasma in a glass rack with blueberries and dark grapes on ivory linen.

The Side Effect They Published: What a Careful Pterostilbene Trial Found in the Bloodwork, and Why the Partner Compound Mattered

In an 80-person trial, pterostilbene lowered blood pressure at the higher dose but raised LDL when taken on its own. In the arm that paired it with a grape extract,...

ALPHA-KETOGLUTARATE, EXAMINED — The Eight-Year Question: One bold claim about biological age, the mouse data behind it, and the trial built to test it. A small brass balance on graphite with a single citrine-yellow bead, lit by warm side light.

The Eight-Year Question: What Alpha-Ketoglutarate Did for Ageing Mice, What One Human Study Claimed, and the Trial Built to Test It

In 2021, 42 people on an AKG formula measured eight years younger on a DNA test, but nobody took a placebo. Discover what alpha-ketoglutarate did for ageing mice, why that...

ENVELHECIMENTO VASCULAR — O revestimento que envelhece: O que uma única camada de células revela sobre as suas artérias e o que mostraram os ensaios com polifenóis. Corte transversal de uma artéria em vidro translúcido, cujo fino revestimento interior brilha em vermelho-rubi sobre um fundo azul meia-noite.

O revestimento que envelhece: o que uma única camada de células revela sobre as suas artérias (e o que mostraram os ensaios com polifenóis)

As artérias envelhecem por dentro, a começar por uma única camada de células e pelo óxido nítrico que ela produz. Descubra como a dilatação mediada pelo fluxo mede esse revestimento,...
