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.

آلفا‑کتوگلوتارات کلسیمی طول عمر موش‌های ماده را تا ۱۶٫۶٪ افزایش داد؛ این برای انسان‌ها چه معنا دارد (و چه نیست)

یک مطالعهٔ ۲۰۲۰ در مجلهٔ Cell Metabolism نشان داد که تغذیهٔ موش‌های میانسال ماده با رژیم ۲٪ آلفا‑کتوگلوتارات کلسیمی (CaAKG) طول متوسط عمر آن‌ها را تا ۱۶٫۶٪ افزایش و ضعیف‌سندی را کم می‌کند. این اثر در نرها کمتر بود و هنوز شواهدی برای انسان‌ها وجود ندارد. در ادامه به جزئیات داده‌ها، تفاوت آن با ادعاهای بازاریابی و محدودیت‌های پژوهش می‌پردازیم.
