A wide, editorial-style still life photographed in soft natural window light, set on a pale oak gym bench or light wooden table. In the foreground, a matte ceramic scoop rests in a small mound of fine white creatine powder, with a few loose grains scattered across the surface. Next to it sits a minimalist frosted glass jar with a plain unbranded label. Beside the jar is a clear glass of water with delicate condensation. A pair of worn chalk-dusted hands is out of focus in the background, wrapping a lifting strap around a barbell. The barbell is a brushed steel bar with a few muted sage-green and warm gray bumper plates.

On the right side of the frame, a small stack of three different supplement capsules and tablets in neutral cream, terracotta, and soft blue sits next to a single clean white scoop of powder. This subtly contrasts the "stack" with the "plain" option. A folded linen towel in oatmeal beige drapes over the end of the bench. A small leather-bound notebook lies open, with a simple hand-drawn line graph showing two lines, one rising steadily and one flat, in pencil.

The background is softly blurred and shows a bright, airy, modern home gym with large windows, pale plaster walls, and a few green plants. Warm morning sunlight casts long, gentle shadows diagonally across the scene. The color palette is muted and sophisticated: cream, warm white, sage green, soft terracotta, and charcoal accents. Shallow depth of field with a crisp focus on the powder and scoop. Generous negative space on the left third for headline overlay. The mood is calm, thoughtful, and trustworthy, like a high-end health and science magazine cover, with subtle film grain and natural textures. No text, no logos, no futuristic elements.

クレアチンスタックは初心者の筋肉量を増やすが、筋力は伸びない――その理由は？

新たに行われたランダム化比較試験で、初心者男性リフターにクレアチン系サプリメント（ブレンド）を4週間投与したところ、筋肉量や回復感は改善したものの、レッグプレス1RMはプラセボと有意差がありませんでした。考えられる要因は、初心者の神経適応が大きいこと、試験期間が短いこと、そして増加した筋肉の一部が水分保持によるものと考えられる点です。腎機能指標は正常範囲に収まっていましたが、サンプル数が少なく男性のみ、かつ産業資金提供という点にも留意が必要です。初心者が最も安全に、根拠のある選択肢として推奨できるのは、依然として単体のクレアチンモノハイドレートです。
