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.

Kapsula od pečuraka podigla VO2max za 14,8 % — ali postoji velika zamka

BY DR. GYMBRO · 29. окт 2026.

Kapsula od pečuraka, 40 dana i rast VO2max‑a od 14,8 % zvuče gotovo previše dobro da bi bilo istinito. U novom radu u časopisu *Antioxidants* 50 mladih sportista je uzimalo 320 mg dnevno ekstrakta bogatog beta‑glukanom i njihova maksimalna potrošnja kiseonika porasla je sa 46,26 na 53,12 mL/kg/min. Velika zamka je što studija nema kontrolnu (placebo) grupu, nije randomizovana i nije slep.

HMB je poboljšao kardio‑kondiciju, a ne snagu, prema istraživanju iz 2026.

BY DR. GYMBRO · 19. окт 2026.

HMB se obično reklamira kao dodatak za očuvanje mišića i povećanje snage, ali trostruko‑slepo istraživanje otkriva drugačije. Kod 90 muškaraca, visoka, personalizovana doza tečnog HMB‑a (90 mg po kg bezmasne mase dnevno) uz visokointenzivni funkcionalni trening povećala je VO2max i prag‑markere više nego placebo. Efekat je bio najizraženiji kod iskusnih sportista, dok se izometrijska snaga nogu nije promenila. Ovde su izračunati doze, poređenje sa standardnom dozinom od 3 g i opis ciljne grupe koja bi najviše imala koristi.

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 arginina + 500 mg vitamina C: Testosteron je porastao za 26 % kod dizača tegova

BY DR. GYMBRO · 18. окт 2026.

Arginin je dugo imao lošu reputaciju kao „čarobni“ pojačivač dušikovog oksida, ali nova randomizovana studija donosi drugačiji pogled – kombinuje ga sa vitaminom C. Kod 50 muških bodybuildera, 3 g arginina (podeljena u tri doze) uz 500 mg vitamina C tokom 45 dana značajno su podigli nivo testosterona i VO₂max u odnosu na placebo, dok je telesna mast opala. Rast hormona rasta, kortizola i azotnog balansa nisu se razlikovali između grupa. Jeftin stack koji vredi pratiti, ali potiče iz jedne male studije i viši testosteron ne garantuje veći mišićni rast.
