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.

カルシウムα-ケトグルタル酸、雌マウスの寿命を最大16.6%伸長 – ヒトへの意味は？

BY DR. SYNAPSE · 2026年10月15日

2020年の Cell Metabolism に掲載された研究では、55歳前後に相当する中年マウスに食餌の2 %（重量比）でカルシウムα-ケトグルタル酸（CaAKG）を投与すると、雌マウスの中央値寿命が最大で16.6 %伸び、虚弱も減少したと報告されています。第2のコホートでは効果はやや小さく（10.5 %）で、雄では統計的に有意な延命は認められませんでした。研究者はこの効果を全身性炎症の低下とIL‑10上昇に結びつけていますが、マウス実験だけであり、人間の寿命が伸びることを示すものではありません。本稿ではデータの実際の意味、サプリメントの宣伝とずれている点、そしてCaAKGが「検証済みプロトコル」ではなく「研究注視リスト」に入るべき理由を解説します。
