A wide, softly lit editorial still life on a pale oatmeal-colored linen surface. In the center sits a small matte ceramic bowl of fine white creatine powder, with a wooden scoop resting beside it and a few loose pale crystals scattered across the linen. Around the bowl, a fresh plant-based spread is arranged in an organic, uncluttered way: a halved avocado, a handful of chickpeas, bright green edamame pods, a cluster of dark leafy kale, a few red lentils spilled from a small wooden spoon, and a split pomegranate with glossy ruby seeds. A tall glass of water with condensation stands on the right, catching a sliver of window light.

In the soft-focus background, a young athlete in a muted sage-green tank top is mid-jump in a bright, minimalist studio with whitewashed brick walls and pale hardwood floors. The figure is slightly blurred and only partly in frame, which gives a sense of motion and vertical lift without pulling attention from the foreground. A pair of clean white sneakers and a folded gray towel sit on a low wooden bench nearby.

The light is warm natural morning daylight from the left. It casts gentle long shadows and subtle highlights on the powder and the glass. The palette is earthy and calm: cream, sage green, terracotta, warm wood tones, and small pops of avocado green and pomegranate red. The depth of field is shallow, with crisp focus on the bowl and scoop. The composition leaves generous negative space on the upper left for a title overlay, in the clean, contemporary style of a modern health and science magazine. Photographic, high-resolution, refined, and minimal.

Vegani su uzeli kreatin četiri tjedna: skokovi su se poboljšali, sprintovi nisu

Vegani jedu gotovo nimalo prehrambenog kreatina, pa će li suplementacija imati veći učinak? Novo randomizirano, trostruko‑slijepo ispitivanje dalo je 20 aktivnim veganima 0,1 g/kg/dan kreatin monohidrata tijekom četiri tjedna. Skokovi su se poboljšali, kao i neki parametri tjelesnog sastava, ali rezultati sprinta, stiska ruke i izometričnog povlačenja srednjeg bedra nisu se promijenili. Tjelesna voda je porasla za 1,4 kg, a studija nije usporedila vegane s mesožderima. Evo što brojevi pokazuju, što ne, i tko bi to mogao isprobati.

A wide, editorial-style photograph of a rugged Himalayan cliff face at golden hour, with dark, glossy resin seeping from the cracks in the layered stone. Thick, tar-like droplets catch the warm light and shine like polished obsidian. In the foreground, a weathered hand holds a small, rustic ceramic dish with a spoonful of purified Shilajit. The resin is deep brown-black, glossy, and stretches in a slow, viscous ribbon from the spoon. Beside the dish sits a simple, minimalist amber glass dropper bottle with a plain cream label, a folded linen cloth, and a few scattered dried herbs, suggesting a modern wellness ritual. The mid-ground shows soft layers of misty mountain ridges fading into a pale peach and dusty blue sky. The background is gently blurred, with shallow depth of field and creamy bokeh. The color palette is earthy and muted: warm ochre, charcoal, sage green, and soft cream, with a subtle film-grain texture. Natural side lighting creates long, gentle shadows and highlights the textures of the stone, resin, and ceramic. The composition follows the rule of thirds, with the dish and bottle in the lower left and open negative space on the right for headline overlay. The mood is calm, grounded, and credible, like a high-end health and science magazine feature, with a refined, contemporary, slightly documentary look. There is no text, no people's faces, and no futuristic elements.

Shilajit testiran: Može li „planinski katran“ stvarno podići testosteron?

BY DR. GYMBRO · 19. lis 2026.

Shilajit, himalajski „planinski katran“ koji se reklamira kao prirodni pojačivač testosterona, testiran je u randomiziranoj, dvostruko slijepoj, placebom kontroliranoj kliničkoj studiji. Kod muškaraca od 45 do 55 godina, doziranje od 250 mg pročistog shilajita dva puta dnevno tijekom 90 dana značajno je podiglo ukupni i slobodni testosteron te DHEAS u odnosu na placebo, dok su LH i FSH ostali stabilni. Istraživanje je obećavajuće, ali ograničeno na sredovječne muškarce i mjeri samo hormonske razine, a ne učinke u teretani. Važno je obratiti pažnju na čistoću proizvoda i provjeru na teške metale pri kupnji.
