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.

Una capsula di funghi ha aumentato il VO2max del 14,8 % — ma c'è un grosso limite

BY DR. GYMBRO ·

Una capsula di funghi, 40 giorni di assunzione e un incremento del VO2max del 14,8 % suonano quasi troppo belli per essere veri. In un nuovo studio pubblicato su *Antioxidants* 50 giovani atleti maschi hanno assunto 320 mg al giorno di un estratto multi‑funghi ricco di beta‑glucani, passando da 46,26 a 53,12 mL/kg/min. Il problema è che lo studio non prevedeva gruppo placebo, né randomizzazione, né cieco, e gli atleti hanno continuato ad allenarsi. Gli esperimenti cellulari su cardiomiociti di ratto suggeriscono un legame con l'ipossia, ma hanno testato composti singoli, non la capsula. Ecco cosa è stato davvero dimostrato, cosa resta incerto e a chi conviene prestare più attenzione.

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 migliora la capacità cardiovascolare, non la forza, nello studio del 2026

BY DR. GYMBRO ·

L'HMB è solitamente promosso come aiuto per mantenere la massa muscolare e accrescere la forza, ma uno studio triplo cieco del 2026 ha svelato qualcosa di diverso. In 90 uomini, una dose personalizzata di acido libero HMB (90 mg per kg di massa magra al giorno) associata a un allenamento funzionale ad alta intensità ha incrementato VO₂max e i parametri di soglia più del placebo. L’effetto è risultato più evidente negli atleti allenati, mentre la forza isometrica delle gambe è rimasta invariata. Ecco come è calcolata la dose, il confronto con la classica dose da 3 g e chi potrebbe trarne beneficio.

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 di Arginina + 500 mg di Vitamina C: il testosterone aumenta del 26 % nei sollevatori

BY DR. GYMBRO ·

Per anni l’arginina è stata liquidata come un esaltatore di ossido nitrico sopravvalutato, ma un nuovo studio randomizzato introduce una svolta: abbinarla alla vitamina C. In 50 bodybuilder maschi, 3 g di arginina (divisi in tre dosi) più 500 mg di vitamina C per 45 giorni hanno aumentato in maniera significativa testosterone e VO2max rispetto al placebo, mentre il grasso corporeo è diminuito. Ormone della crescita, cortisolo e bilancio azotato non sono cambiati in modo significativo tra i gruppi. È una combinazione economica da tenere d’occhio, ma proviene da un unico piccolo studio e un testosterone più alto non garantisce più muscoli.
