A wide, softly lit editorial still life on a pale warm-gray concrete surface, shot from a slightly elevated three-quarter angle. In the center-left, two matte ceramic scoops sit side by side. One holds fine ivory whey powder, the other holds slightly coarser, pale golden collagen peptide powder. A small, elegant dusting of both powders spills between them and blends into a soft swirl. Behind them, three minimalist cream and sage-green supplement tubs with no legible text stand in a staggered row, with a frosted glass shaker bottle of creamy liquid beside them.

On the right, a brushed-steel barbell plate and a compact chalk-dusted kettlebell rest slightly out of focus, suggesting resistance training. Pale wisps of chalk hang in the air. A folded charcoal gym towel and a pair of worn leather lifting straps lie in the foreground. A single cross-section of a clean white bone model, a stylized vertebra, rests on a small oak block at the far right. It subtly signals the bone-density theme without looking clinical.

Natural window light enters from the left, casting long, gentle shadows and a warm highlight on the powders. The palette is muted and modern: oatmeal, bone white, sage green, soft charcoal, and touches of warm amber. Shallow depth of field keeps the scoops tack-sharp and melts the background into creamy blur. Leave generous negative space in the upper right for headline overlay. The overall feel is a premium health and science journal cover: clean, tactile, minimalist, with fine film-like grain and a calm, editorial mood.

Whey + kolagen nadmašuje pojedinačne suplementacije kod dizača – uz jedan uslov

Mešanje 30 g whey proteina i 10 g kolagena dalo je bolje rezultate od whey‑a, kolagena i placeba po svim parametrima u osmonedeljnoj studiji na muškarcima koji treniraju snagom. Kombinacija je povećala mišićnu masu za 2,66 kg (prema BIA), podigla mineralnu gustinu kostiju lumbalne kičme i unapredila snagu u čučnju i benč preseku, kao i biomarkere kostne rezorpcije i formacije. Sam kolagen je podigao samo gustinu kostiju, whey je podigao samo mišiće. Međutim, uz 40 učesnika, neujednačene količine proteina i neobično veliki skok BMD‑a, postoji jedan uslov koji mora da se uzme u obzir. U nastavku su prikazane pobede, ko bi trebao koristiti ovaj stack i ko bi ga trebalo izbegavati.

A bright, airy editorial flat-lay shot from slightly above, on a soft warm-white linen surface with gentle natural window light and long, soft shadows. Two small ceramic dishes sit side by side at the center. The left dish holds a single small capsule in muted terracotta. The right dish holds one small capsule in the same color, with a noticeable empty space beside it to suggest rhythm and spacing. Between them lies a minimalist wooden calendar block or a row of seven small round ceramic discs in alternating tones, dusty rose and cream, evoking an every-other-day pattern. Around the dishes are fresh, iron-rich foods arranged with restraint: a halved blood orange, a few deep green spinach leaves, a small scattering of pumpkin seeds, and a sprig of parsley. A folded sage-green athletic towel and a slim, modern water bottle sit at the upper edge, hinting at women who train. A matte ceramic mug of herbal tea sits at the right with a faint curl of steam. A small notebook with a pen lies open at the lower left, its pages blank, suggesting lab results and tracking without any legible text. The palette is soft and cohesive: warm cream, dusty rose, terracotta, sage green, with small accents of deep coral. The mood is calm, clean, and wellness-oriented, like a contemporary health and science journal feature. Shallow depth of field keeps the capsules sharp and softly blurs the edges of the frame. The composition leaves generous negative space on the left third for title overlay. The look is a high-end lifestyle photograph with subtle film grain, natural textures, and refined minimalism, with no people, no text, and no futuristic or laboratory elements.

Manje gvožđa, svaki drugi dan: isti porast feritina kod žena

BY DR. GYMBRO · 26. окт 2026.

Hepcidin može da smanji apsorpciju gvožđa nakon jedne doze, zbog čega oralni suplement često razočara i izazove gastrointestinalne tegobe. Randomizovani pokušaj iz 2026. godine na 66 žena sa nedostatkom gvožđa ispitao je 21 mg gvožđa svakih 48 h naspram 30 mg dnevno tokom 42 dana. Feritin je značajno porastao u obe grupe, bez statistički značajne razlike, dok je hemoglobin ostao stabilan, a gastrointestinalni efekti bili su blagi. Studija je bila aktivno kontrolisana, bez placeba, i korišćeni su različiti oblici gvožđa, pa se rezultati mogu uporediti, a ne tvrditi da su superiorniji.
