A wide, editorial-style flat lay photographed from above on a pale, warm-gray stone surface lit by soft natural window light. On the left, a matte white supplement sachet and a small frosted glass jar of off-white probiotic powder sit beside a wooden scoop dusted with fine granules. In the center, a modern minimalist stopwatch with a brushed silver case and crisp white face rests on a folded slate-blue running towel, its hands frozen just past the half-minute mark. On the right, a pair of sleek running shoes in cream and sage green are angled diagonally, with a few strands of laces trailing across the surface. Scattered around the arrangement are fresh, natural gut-health cues: a halved kefir-colored ceramic bowl of creamy yogurt with a drizzle of honey, a few sprigs of fresh mint, sliced green apple, and a handful of raw oats. A small glass of water with delicate condensation catches a soft highlight in the background. The color palette is calm and refined: sage green, cream, soft slate blue, and touches of warm honey gold against the neutral stone. Shadows are long and gentle, creating depth and a quiet, premium wellness-journal mood. The shallow depth of field softly blurs the edges, leaving the stopwatch and probiotic jar in crisp focus. Negative space on the upper right of the composition leaves room for a headline overlay. The overall feel is clean, modern, and trendy, like a contemporary health and sports science magazine cover, with realistic textures, natural tones, and no futuristic or digital elements.

SLAB51 probiotik: jedan tjedan donosi 33 sekunde dodatnog vremena elitnim sportašima

BY DR. GYMBRO · 17. lis 2026.

Tjedni unos multi‑slojnog probiotika SLAB51 pomogao je elitnim sportašima da izdrže otprilike 33 sekunde duže na testu na traci, dok jedinstvena doza nije pokazala učinak, a VO2max se nije promijenio. Randomizirano, dvostruko slijepo križno ispitivanje otkrilo je i povišenu razinu antioksidativnog enzima SOD prije vježbe. Što je SLAB51 i zašto crijevne bakterije mogu utjecati na izdržljivost? Ovaj članak razlaže dizajn studije, rezultate i praktične implikacije te ističe ograničenja: mali uzorak elitnih muškaraca i vrlo kratak period intervencije.

A cyclist's legs mid-pedal on a stationary road bike, shot in a bright, airy, minimalist studio with a soft warm-grey backdrop. In the foreground on a pale oak table sits a small ceramic dish holding four deep coral-red softgel capsules, with a few translucent droplets of red-orange oil glistening beside them. Beside the dish is a sprig of dried red microalgae-toned seaweed and a halved wild salmon fillet, its coral flesh echoing the capsule color. Behind the table, slightly out of focus, a cyclist in a fitted charcoal jersey and matte black shorts rides a bike on an indoor trainer. Only the torso and legs are visible, with no face. A white towel hangs over the handlebars and a clear water bottle catches the light.

Soft diffused morning light streams from a large window on the left, creating long gentle shadows and a subtle golden-hour glow on the skin and the glossy capsules. The palette is restrained and editorial: warm cream, sand, soft grey and charcoal, with vivid coral-red as the single accent color. A minimalist analog stopwatch with a clean white face sits on the table, its hands near the 85-minute mark. A thin, elegant line-graph shape is subtly suggested by a curved strip of red ribbon lying on the table, rising from left to right to hint at the performance gain without any text.

The composition follows the rule of thirds, with the capsules and stopwatch in the lower left and the cyclist's motion-blurred legs sweeping across the right. Shallow depth of field, crisp macro detail on the capsules, and a fine film-like grain. The overall feel is a modern health and science magazine cover: clean, calm, sophisticated, and natural, with negative space in the upper area for a headline. There are no futuristic elements, no glowing effects, no laboratory equipment, and no text or logos. Landscape 16:9 format.

Astaxanthin povećao vrijeme do iscrpljenosti u biciklizmu za 13 minuta (72 → 85) nakon samo 4 dana suplementacije u malom istraživanju

BY DR. GYMBRO · 15. lis 2026.

Četiri dana suplementacije astaxanthinom (28 mg dnevno) produžila su vrijeme do iscrpljenosti na ergometru s otprilike 72 na 85 minuta – povećanje od oko 18 %. Istovremeno su se smanjili porasti enzima oštećenja mišića (CK i LDH) i biomarkera lipidne peroksidacije (MDA) nakon napornog testiranja pri 75 % VO₂max. Markeri upale i potrošnja goriva ostali su nepromijenjeni, pa mehanizam ostaje nejasan. Doza je znatno iznad onoga što sadrže većina komercijalnih kapsula, a studija je obuhvatila samo deset mladih muškaraca. Evo što podaci pokazuju i gdje dokaz prestaje.
