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。

A bright, airy editorial flat-lay shot from slightly above, on a soft warm-white linen surface with gentle natural window light and long, soft shadows. Two small ceramic dishes sit side by side at the center. The left dish holds a single small capsule in muted terracotta. The right dish holds one small capsule in the same color, with a noticeable empty space beside it to suggest rhythm and spacing. Between them lies a minimalist wooden calendar block or a row of seven small round ceramic discs in alternating tones, dusty rose and cream, evoking an every-other-day pattern. Around the dishes are fresh, iron-rich foods arranged with restraint: a halved blood orange, a few deep green spinach leaves, a small scattering of pumpkin seeds, and a sprig of parsley. A folded sage-green athletic towel and a slim, modern water bottle sit at the upper edge, hinting at women who train. A matte ceramic mug of herbal tea sits at the right with a faint curl of steam. A small notebook with a pen lies open at the lower left, its pages blank, suggesting lab results and tracking without any legible text. The palette is soft and cohesive: warm cream, dusty rose, terracotta, sage green, with small accents of deep coral. The mood is calm, clean, and wellness-oriented, like a contemporary health and science journal feature. Shallow depth of field keeps the capsules sharp and softly blurs the edges of the frame. The composition leaves generous negative space on the left third for title overlay. The look is a high-end lifestyle photograph with subtle film grain, natural textures, and refined minimalism, with no people, no text, and no futuristic or laboratory elements.

鉄分を減らして隔日摂取：女性のフェリチン上昇は同等

BY DR. GYMBRO · 2026年10月26日

ヘプシジンは1回の服用で鉄の吸収を抑制するため、経口鉄が胃に負担をかけやすい原因と考えられています。2026年に実施されたランダム化比較試験では、鉄欠乏女性66名を対象に、21 mgを48時間ごとに投与する群と、30 mgを毎日投与する群で、計42日間追跡しました。結果、両群とも血清フェリチンは有意に上昇し、群間差は統計的に認められませんでした。ヘモグロビンは安定し、胃腸症状も軽度にとどまりました。ただし、プラセボ無しの比較であり、使用した鉄製剤が異なる点から、優位性を示すエビデンスとは言えません。
