A softly lit, editorial-style flat lay on a pale oat-colored linen surface, shot from slightly above at a gentle angle. On the left, a matte ceramic bowl in warm cream holds a small mound of fine white collagen peptide powder, with a wooden scoop resting beside it and a light dusting of powder on the linen. In the center, a tall frosted glass of water with a faint swirl of dissolving powder catches soft window light. On the right, a single brushed-steel dumbbell with a muted charcoal grip sits partly in frame, with a rolled sage-green gym towel beside it. A small, clean, minimalist notebook lies open near the bottom edge with a thin pen and a few handwritten lines and a simple hand-drawn bar chart showing two bars of different heights. This subtly hints at data and scrutiny without any legible text. A sprig of dried eucalyptus adds an organic touch in the upper corner.

The light is warm morning sunlight from the left, producing long, soft shadows and a gentle golden glow, with a shallow depth of field that blurs the background edges into creamy neutrals. The palette is restrained and modern: oat, cream, sage, soft terracotta, and charcoal accents. The composition leaves open negative space on the upper right for title overlay. The overall mood is calm, thoughtful, and wellness-meets-science, in the style of a contemporary health and nutrition magazine, with crisp textures, natural grain, and a clean, trendy, slightly muted film-like finish.

コラーゲンペプチドで筋肉内コラーゲンIが約3倍に増加――その意味と限界

BY DR. GYMBRO · 2026年11月1日

12 週間の高強度レジスタンストレーニングと、1 日あたり 15 g の特定コラーゲンペプチド（SCP）摂取により、太ももの外側大腿四頭筋の筋組織内コラーゲン I が 29.8 % 増加（プラセボは 9.9 %）したと報告された。生体組織の生検というハードエンドポイントが得られた点は希少だが、筋力・筋肥大のデータは示されていない。さらに、共著者の一人がコラーゲン関連特許を保有していることから、利益相反にも留意が必要である。本稿では、本研究が示すこと・示さないこと、そしてどのような読者が関心を持つべきかを整理する。
