A bright, minimalist flat-lay photograph of two supplement scoops on a pale warm-gray stone surface, shot from directly above in soft natural window light. On the left, a matte ceramic scoop holds fine white creatine monohydrate powder, heaped in a clean mound. On the right, a second scoop of the same shape holds slightly coarser off-white beta-alanine powder, with a small, deliberate gap between the two. Each scoop sits in its own soft shadow, which suggests separation rather than combination. Between them, a thin brushed-brass ruler or a single slim line of fine powder runs across the surface and subtly divides the composition.

Around the scoops, a few restrained props in a muted editorial palette of sage green, cream, terracotta, and soft charcoal: a small glass jar with a minimalist label that has no readable text, a folded linen napkin, a single sprig of eucalyptus, and a stainless-steel shaker bottle softly out of focus in the upper corner. A few loose powder grains are scattered naturally across the stone. A small stack of blank cream index cards with a pencil rests in the lower right, hinting at research and note-taking without any legible writing.

The composition follows a clean rule-of-thirds layout, with generous negative space on the right third for headline overlay. The lighting is gentle and diffused, with long, soft shadows falling to the lower left. The color grading is calm and slightly desaturated, with creamy highlights and a subtle film-like grain. The overall look is a modern wellness and science journal cover, with an airy, trustworthy, contemporary editorial feel, shallow depth of field, and crisp detail on the powders.

Kreatin + beta‑alanin: Bonus za stack koji istraživači nisu otkrili

BY DR. GYMBRO · 28. lis 2026.

Stack kreatin + beta‑alanin često se reklamira kao snažan par za vrhunske sportske rezultate, ali nova mrežna meta‑analiza 52 randomizirana klinička ispitivanja nije otkrila sinergiju. Kreatin je sam po sebi značajno poboljšao sprint, skok, ponovljene sprintove i izdržljivost gornjeg dijela tijela, dok su učinci beta‑alanina bili ne‑značajni ili specifični za određene uvjete, a kombinacija nije donijela dodatnu prednost.

A wide, editorial-style still life shot from a slightly elevated angle on a pale, warm-gray concrete surface lit by soft natural window light from the left. In the center foreground, a clear glass of cloudy water sits beside a small white ceramic bowl heaping with fine white baking soda powder, a wooden measuring spoon resting beside it with a light dusting of powder spilling across the surface in a graceful arc. Next to them, a minimalist digital kitchen scale in matte white shows a small portion of powder in a shallow dish. Slightly behind, an orange basketball is partially in frame, its pebbled texture catching the light, resting beside a pair of clean white and coral athletic sneakers with the laces loosely undone. A folded charcoal gray towel and a stainless steel stopwatch lie to the right, the stopwatch face crisp and legible. Three small, neatly arranged piles of white powder on a slate tile in the midground, in ascending sizes, hint at different doses without any text or labels. In the soft-focus background, the faint outline of an indoor basketball court with warm honey-colored hardwood floor and blurred lane lines stretches across the frame, glowing with golden-hour light. The color palette is restrained and modern: warm off-white, soft gray, burnt orange, and touches of sage green from a single sprig of mint or eucalyptus laid near the glass. Shallow depth of field, crisp textures on powder grains and the ball's surface, gentle shadows, subtle film-like grain. Clean negative space in the upper right for headline overlay. The mood is calm, sleek, and contemporary, like a premium health and sports science magazine cover, with a fresh, minimalist composition and no people, no text, and no futuristic elements.

Soda bikarbona + sprintovi: Doza koja je nadmašila placebo u svakom testu

BY DR. GYMBRO · 27. lis 2026.

Novi randomizirani pokus na košarkašima otkrio je da dodavanje natrijevog bikarbonata (sode bikarbone) uz četiri tjedna sprint‑intervalnog treninga nadmašuje placebo u skakanju, sprintu, agilnosti, Yo‑Yo udaljenosti i Wingate snazi. Veća doza od 0,45 g/kg bila je bolja od 0,30 g/kg u svakom mjerenju. To čini dodatak jeftinim i privlačnim za sportaše timskih sportova, ali uz mogućnost gastrointestinalnih smetnji. Studija je mala, kratka i provedena isključivo na muškarcima. Evo kako izračunati dozu, ublažiti gastrointestinalne probleme i kome je dodatak zapravo namijenjen.
