A landscape editorial still life on a soft, warm oat-colored linen surface, lit by diffused natural window light from the left. In the center sits a shallow matte ceramic bowl in muted sage green holding a small mound of fine white arginine powder. Beside it rests a wooden scoop dusted with powder. To the left, a loose arrangement of dried Astragalus root slices, pale golden and delicate, fans out in a graceful curve. To the right, a few whole Panax notoginseng roots, knobbly and earthy brown, sit next to a small pile of finely ground tan powder on a folded cream paper. A single sprig of fresh green leaf adds a gentle accent in the background.

In the foreground, a minimalist glass beaker with clear water and a thin linen-wrapped glass dropper sit slightly out of focus. Behind the objects, a softly blurred backdrop in pale blush and sand tones carries a faint, abstract pattern of soft circular shapes, like ripples or molecular dots drawn in subtle terracotta ink. A thin hand-drawn line graph in dusty coral rises gently across the upper right of the background, as if sketched on textured paper, with no readable text.

The composition uses generous negative space on the upper left, which leaves room for a headline overlay. The palette is earthy and calm: sage, cream, terracotta, honey gold, and soft blush. The shallow depth of field gives creamy bokeh. Gentle shadows fall to the right. The overall feel is clean and contemporary, like a wellness and science journal cover, with subtle film grain, high-end editorial photography, and tactile natural textures.

小規模試験でアルギニン吸収が17%向上したサプリメント

BY DR. GYMBRO ·

2023 年に実施されたクロスオーバー試験で、5 g のアルギニンにアストラガルス抽出物とパナックス・ノトーギンセン由来のサポニン(以下 APS)を併用すると、アルギニンの吸収が 17.3% 増加し、アルギニン/ADMA 比が 167.1% 上昇することが明らかになりました。尿中硝酸塩と cGMP という一酸化窒素(NO)マーカーも増加しています。ですが、個人差が大きい 6 名が除外され、最終的に解析されたのは 24 名のみで、運動パフォーマンスは評価されていません。本記事では、データが示すこと・示さないこと、そして注意すべき対象者について解説します。

A wide, editorial-style flat lay photographed from above on a pale warm-gray stone countertop in soft morning window light. On the left, a small matte white ceramic bowl holds fine white arginine powder, with a wooden scoop resting beside it. At the center, two halved oranges and one whole lemon in saturated citrus tones, with a few glossy droplets of water on the cut surfaces, to suggest vitamin C. On the right, three slim amber glass capsule bottles with minimal cream labels and no legible text stand in a loose row, with a few white capsules spilling out. A single chrome dumbbell handle enters the frame from the upper right corner, partly cropped, its cool metallic sheen contrasting with the warm fruit. A sprig of green rosemary and a folded linen napkin in oatmeal beige add texture. Long soft shadows fall to the left. The palette is warm cream, sunny orange, soft yellow, and muted sage, with a few crisp accents of steel gray. The composition is airy and uncluttered, with generous negative space in the upper left for a title overlay. It has a shallow depth of field, a crisp foreground, and a faintly blurred background. The look is clean, contemporary, and wellness-magazine, like a premium health and fitness journal cover, with natural grain, high-end product photography quality, and a calm, fresh, trustworthy mood.

3 g アルギニン+500 mg ビタミンCでテストステロンが26%上昇

BY DR. GYMBRO ·

アルギニンは過大評価された一酸化窒素ブースターとして長らく注目されてきましたが、最新のランダム化比較試験でビタミンCと併用すると効果が出ることが示されました。50名の男性ボディビルダーに、45日間 3 g のアルギニン(1日3回に分割)と 500 mg のビタミンCを投与したところ、プラセボ群と比べて血清テストステロンと VO₂max が有意に上昇し、体脂肪が減少しました。成長ホルモン、コルチゾール、窒素バランスには有意差が認められませんでした。この安価なスタックは注目に値しますが、規模の小さい単独試験の結果に過ぎず、テストステロンが上がったからといって筋肉が増える保証はありません。
