A wide landscape editorial photograph of a minimalist laboratory-meets-wellness still life on a pale, warm-gray stone countertop, softly lit by diffused morning window light from the left. In the center foreground, a small amber glass supplement jar with a plain matte white label sits beside a scattering of fine white powder and a few loose white capsules on a ceramic dish. Next to it rests a clean, open notebook with faint hand-drawn line graphs, two diverging curves rising gently, one slightly higher than the other, drawn in muted sage-green and charcoal ink. A slim brass pen lies across the page.

In the soft-focus midground, a delicate glass beaker filled with clear liquid catches a thin streak of light, casting a gentle caustic shimmer across the stone. A sprig of dried eucalyptus and a small sliver of citrus peel add organic texture. Behind them, an out-of-focus wall of pale oat-colored tiles and a floating wooden shelf holds a few blurred ceramic vessels and a small potted fern.

The color palette is calm and editorial: warm creams, sage green, soft amber, muted terracotta accents, and touches of charcoal. Shallow depth of field with a crisp focus on the jar and notebook, creamy bokeh in the background. Subtle film-like grain, natural shadows, and generous negative space on the right third of the frame, suitable for headline overlay. The mood is thoughtful, measured, and trustworthy, like a contemporary science and wellness journal cover: modern, tactile, quietly optimistic, and grounded rather than hyped.

Cálcio Alfa‑Cetoglutarato Prolongou a Expectativa de Vida de Camundongas Fêmeas em até 16,6 %

BY DR. SYNAPSE ·

Um estudo de 2020 publicado na *Cell Metabolism* mostrou que, ao suplementar camundongos de meia‑idade com 2 % de cálcio alfa‑cetoglutarato, a expectativa de vida mediana das fêmeas aumentou em até 16,6 % e a fragilidade diminuiu. O efeito foi menor na segunda coorte (10,5 %) e não foi estatisticamente significativo nos machos. Os autores atribuem o benefício à redução da inflamação sistêmica e ao aumento de IL‑10, mas trata‑se de um experimento apenas em camundongos, sem comprovação de eficácia em humanos. A seguir, explicamos o que os dados realmente demonstram, como eles divergem das promessas de suplementos e por que o CaAKG deve permanecer na lista de observação da pesquisa, e não como um protocolo comprovado.
