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.

Doplněk, který zvýšil vstřebávání argininu o 17 % v malém testu

Křížová studie z roku 2023 zjistila, že kombinace 5 g argininu s kapslí obsahující saponiny z astragalu a Panax notoginseng (APS) zvýšila vstřebávání argininu o 17,3 % a poměr arginin/ADMA posunula o 167,1 %. Současně vzrostly i močové koncentrace dusičnanů a cGMP – dva ukazatele oxidu dusnatého. Studie však zahrnovala pouze 24 analyzovaných účastníků a neprověřovala sportovní výkon. V následujícím textu rozebereme, co data skutečně dokazují, co ne a pro koho je třeba být opatrný.

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 argininu + 500 mg vitamínu C: Testosteron stoupl o 26 % u kulturistů

BY DR. GYMBRO · 18. 10. 2026

Arginin byl dlouho považován za nadhodnocený podnětník dusičnaného oxidu, ale nová randomizovaná studie přináší zvrat – kombinaci s vitamínem C. U 50 mužských kulturistů po 45 dnech užívání 3 g argininu (rozdělených do tří dávek) a 500 mg vitamínu C došlo k výraznému zvýšení testosteronu i VO2max ve srovnání s placebem a zároveň k úbytku tělesného tuku. Růstový hormon, kortizol ani dusíková bilance se mezi skupinami významně nelišily. Jedná se o levný stack, který stojí za pozornost, ale pochází jen z jedné malé studie a vyšší testosteron nezaručuje větší svalovou hmotu.
