A wide, editorial-style flat lay photographed from above on a pale warm-gray linen surface in soft natural window light. At the center, a small open amber glass jar tips gently onto its side, spilling a few cream-colored capsules across the fabric. Next to the jar sits a loose arrangement of fresh mushrooms: a cluster of golden-tan reishi with glossy, lacquered caps, a few slender white enoki stems, a halved shiitake showing its pale gills, and a curl of turkey tail with concentric bands of rust, cream, and charcoal. A small wooden scoop holds a pile of fine beige mushroom powder.

On the left third of the frame, a matte black sports watch with a minimal face lies beside a folded sage-green running shirt and a pair of lightweight off-white running shoes, hinting at athletic training without showing a person. A slim white notebook with a single pencil rests nearby, open to a blank page with a faint hand-drawn line graph trending upward, in thin graphite strokes.

On the right side, a pair of clear glass beakers and a single small petri dish with a soft amber-tinted liquid add a subtle laboratory note, kept calm and organic. A single sprig of dried herbs and a few scattered oat-colored grains add texture.

The palette is earthy and refined: oatmeal, soft sage, terracotta, warm amber, and charcoal accents against the muted neutral background. Shadows are soft and diffused, with a gentle highlight on the glass and the glossy reishi cap. The composition leaves generous negative space in the upper right for a headline overlay. Shallow depth of field blurs the edges slightly, while the central mushrooms and capsules stay crisp. The overall feel is modern, clean, and trendy, like a wellness and science magazine cover, with tactile natural textures, minimal styling, and a quiet sense of curiosity and skepticism.

Eine Pilzkapsel steigerte VO2max um 14,8 % – aber es gibt einen großen Haken

BY DR. GYMBRO ·

Eine Pilzkapsel, 40 Tage und ein Anstieg von 14,8 % im VO2max klingen fast zu schön, um wahr zu sein. In der neuen *Antioxidants*-Studie verbesserten 50 junge männliche Athleten, die täglich 320 mg eines beta‑Glukan‑reichen Mehrpilz‑Extrakt‑Komplexes einnahmen, ihr VO2max von 46,26 auf 53,12 mL/kg/min. Der große Haken: Es gab keine Placebo‑Gruppe, keine Randomisierung und kein Blind‑Design, und die Sportler trainierten währenddessen weiter. Zellversuche an Rattenherzzellen lieferten Hinweise im Zusammenhang mit Hypoxie, testeten jedoch Einzelsubstanzen, nicht den kompletten Extrakt.

In the foreground, a clear glass vial of pale amber liquid sits on a matte white stone surface, with a small dropper beside it and a few droplets catching soft light. A slim brushed-steel measuring spoon and a minimalist notebook with handwritten dose calculations in pencil rest nearby. The numbers are blurred and unreadable.

In the softly blurred background, a bright, airy modern gym with large windows and morning light. A fit man in his thirties, in a charcoal athletic shirt, is mid-stride on a treadmill in profile, with a gentle sheen of sweat and a focused expression. Behind him, a wooden plyo box, a kettlebell, and a rope are arranged neatly, suggesting functional training.

The palette is calm and refined: warm cream, soft sage green, muted terracotta, and touches of deep navy. Natural golden side-light makes long, gentle shadows. Shallow depth of field with a crisp foreground and creamy bokeh. Clean composition with negative space on the left third for a title overlay. Premium magazine photography, subtle film grain, realistic textures, no text or logos, and no futuristic or digital elements.

HMB verbessert die kardiovaskuläre Fitness, nicht die Kraft – neue Studie 2026

BY DR. GYMBRO ·

HMB wird meist als Mittel angepriesen, das Muskelmasse erhalten und die Kraft steigern soll, doch eine neue dreifach‑blinde Studie zeigte etwas anderes. Bei 90 Männern führte eine an die fettfreie Körpermasse angepasste, hohe Dosis flüssiger HMB‑Freisäure (90 mg pro kg fettfreie Masse pro Tag) in Kombination mit hochintensivem funktionalem Training zu einer stärkeren Steigerung von VO₂max und Schwellenwert‑Markern im Vergleich zum Placebo. Der Effekt fiel vor allem bei trainierten Männern aus, während die isometrische Beinkraft unverändert blieb. Hier die Dosierungsrechnung, der Vergleich zur üblichen 3‑g‑Dosis und die potenzielle Zielgruppe.

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 Arginin + 500 mg Vitamin C: Testosteron um 26 % erhöht bei Bodybuildern

BY DR. GYMBRO ·

Arginin gilt seit Jahren als überbewerteter Stickstoffmonoxid‑Booster – doch eine neue randomisierte Studie kombiniert es mit Vitamin C. Bei 50 männlichen Bodybuildern erhöhten 3 g Arginin (aufgeteilt auf drei Dosen) plus 500 mg Vitamin C über 45 Tage sowohl das Testosteron als auch die VO₂max deutlich im Vergleich zu Placebo, während das Körperfett sank. Wachstumshormon, Cortisol und der Stickstoffhaushalt blieben unverändert. Der Stack ist günstig und interessant, stammt aber aus einer kleinen Studie – ein höheres Testosteron bedeutet nicht automatisch mehr Muskelmasse.
