#citrulline

A bright, minimalist editorial still life shot from a slightly elevated three-quarter angle on a pale oat-colored stone countertop, bathed in soft natural window light with gentle long shadows. In the center sit two matching matte white supplement scoops, side by side. One is heaped with fine white crystalline powder, the other holds an almost identical pile, so the viewer is invited to compare them. Beside them are two simple frosted glass tumblers of cloudy water, each with a small whisper of powder swirling at the bottom. A third glass of clear water sits slightly apart, as a quiet nod to the placebo.

Scattered around the scene are fresh, sliced watermelon wedges with vivid coral-pink flesh and pale green rinds, and a few sliced green apples with crisp white interiors, hinting at the natural sources of citrulline and malic acid. A small brushed-brass measuring spoon and a minimalist matte sage-green shaker bottle rest at the edge of the frame. Off to one side, a clean ceramic dish holds a few loose grains of powder, and a slim linen notebook with a pencil lies open to a blank page, suggesting data and study notes without any legible text.

The color palette is soft and modern: warm cream, blush coral, sage green, and touches of brass, with a faintly blurred background of a sunlit kitchen or studio with a pale plaster wall. Shallow depth of field keeps the scoops tack sharp while the background melts into a creamy bokeh. The composition leaves generous negative space on the left third of the frame for a title overlay. The overall mood is calm, trustworthy, and trendy, like a contemporary wellness and science journal cover, with crisp detail, subtle film-like grain, and a clean, airy, balanced feel.

シトルリンマレート vs L‑シトルリン：マレートは本当に意味があるのか？

シトルリンマレートとプレーンな L‑シトルリン、どちらを選べばよいのでしょうか？ 43 名のトレーニング経験者を対象にした二重盲検・プラセボ対照クロスオーバー試験の結果、どちらの形態も筋力・パワー・ジャンプ性能・レップ数・主観的負荷感に有意な向上を示さず、マレートはシトルリンと同量を与えるだけでは効果を付加しませんでした。本稿では、研究で測定された項目や投与量、そして結論に至るまでの留意点を解説します。シェーカーに何を入れるか迷っている方は、まずここから読んでみてください。

A wide, editorial-style flat lay photographed from above on a pale warm-gray concrete surface, lit by soft natural window light with gentle long shadows. On the left, two matte ceramic bowls in muted sage green and cream sit side by side. One holds fine white crystalline powder, the other holds slightly coarser off-white powder. Between them, a small brass measuring scoop rests on the surface, dusted with powder. Behind the bowls, two simple amber glass jars with minimal cream labels and no legible text stand slightly out of focus.

On the right side, a pair of chalk-dusted black hex dumbbells and a worn leather lifting strap curve across the frame. A folded charcoal gym towel sits beneath them. A rumpled matte-black shaker bottle lies on its side near the top edge. A slice of watermelon, the natural source of citrulline, sits on a small white ceramic plate in the lower center. Its vivid coral-pink flesh and dark seeds add a saturated pop of color against the neutral palette. A few loose watermelon seeds and a scattering of white powder dust trail across the surface toward the dumbbells, tying the composition together.

In the lower left corner, an open notebook with blank cream pages holds a slim silver pen and a minimalist analog stopwatch. A thin line of hand-drawn tally marks suggests counted reps, with no readable words or numbers.

The palette is restrained and contemporary: warm grays, sage, cream, charcoal, and amber, with the watermelon's coral-pink as the single bright accent. The mood is calm, clean, and precise, like a modern wellness or science-journal feature. Shallow depth of field keeps the powder bowls and watermelon crisp while the background items soften slightly. Generous negative space across the upper center leaves room for a headline overlay. The photograph looks high-end and tactile, with a subtle film-grain finish.

L-シトルリン vs シトルリンマレート：上半身持久力にひとひねり

BY DR. GYMBRO · 2026年10月16日

プラセボと比較したとき、L‑シトルリンとシトルリンマレートのどちらがコスパが良いかという議論は根強いが、6 週間の新たなトライアルでは興味深い結果が出た。両形態とも上半身の限界レップ数が増加し、血中の一酸化窒素代謝産物（NOx）も上昇した。一方で 1RM の最大筋力は変化せず、下半身の結果は統計的に有意ではなかった。被験者は 33 名のトレーニング経験者に限られるため、結論というよりは有望なシグナルと捉えるべきだ。ここでは用量、摂取タイミング、実務上のポイントを解説する。
