A wide, softly lit editorial still life on a pale warm-gray concrete surface, shot from a slightly elevated three-quarter angle. In the center-left, two matte ceramic scoops sit side by side. One holds fine ivory whey powder, the other holds slightly coarser, pale golden collagen peptide powder. A small, elegant dusting of both powders spills between them and blends into a soft swirl. Behind them, three minimalist cream and sage-green supplement tubs with no legible text stand in a staggered row, with a frosted glass shaker bottle of creamy liquid beside them.

On the right, a brushed-steel barbell plate and a compact chalk-dusted kettlebell rest slightly out of focus, suggesting resistance training. Pale wisps of chalk hang in the air. A folded charcoal gym towel and a pair of worn leather lifting straps lie in the foreground. A single cross-section of a clean white bone model, a stylized vertebra, rests on a small oak block at the far right. It subtly signals the bone-density theme without looking clinical.

Natural window light enters from the left, casting long, gentle shadows and a warm highlight on the powders. The palette is muted and modern: oatmeal, bone white, sage green, soft charcoal, and touches of warm amber. Shallow depth of field keeps the scoops tack-sharp and melts the background into creamy blur. Leave generous negative space in the upper right for headline overlay. The overall feel is a premium health and science journal cover: clean, tactile, minimalist, with fine film-like grain and a calm, editorial mood.

ホエイ＋コラーゲンは単独より効果的――ただし留意点あり

抵抗トレーニングを行う男性40名を対象に、ホエイ30 gにコラーゲン10 gを加えた組み合わせが、ホエイ単独、コラーゲン単独、プラセボのいずれよりも全ての指標で優れた結果を示した。筋肉量は平均で2.66 kg増加し、腰椎の骨密度も0.108 g/cm²上昇した。筋力はスクワットとベンチでそれぞれ15.2 kg、10.6 kgの増加が見られた。コラーゲン単体は骨に、ホエイ単体は筋肉に主な効果があったが、サンプル数の少なさやタンパク質総量の違いなど、結果を過大評価しないための留意点も多い。
