A wide, softly lit editorial flat-lay on a pale warm-gray stone countertop, shot from slightly above. On the left, a small rustic ceramic bowl in matte cream holds a handful of dried guarana seeds, dark glossy brown with pale cream arils, a few spilling onto the surface. Beside it sits a halved fresh guarana fruit in vivid red-orange, split open to show the white flesh and black seed inside, looking like a tiny eye. On the right, two open clear capsules rest side by side. One is filled with fine white caffeine powder, the other with a fine earthy brown guarana powder, and a little of each dusts the stone in delicate, deliberate lines. Between them, a minimalist matte-black espresso cup with a thin ribbon of steam rises on the right edge of the frame. A brushed-steel stopwatch and a slim dark-green linen notebook with a pencil sit in the upper background, slightly out of focus, to hint at performance testing without clutter. A few green leaves of a guarana vine curve in from the top-left corner, catching soft light.

The lighting is natural window light from the left, with gentle long shadows and a subtle warm highlight on the seeds. The palette is muted and modern: warm creams, terracotta red, deep espresso brown, sage green, and charcoal accents. The background is clean with generous negative space on the upper right for headline text. Shallow depth of field, crisp focus on the seeds and capsules, fine grain, and a calm premium magazine look like a contemporary wellness and sports-science journal. No people, no text, no logos, no futuristic elements.

Guarana vs Caffeine: Same Dose, Only Guarana Lifted Peak Power

BY DR. GYMBRO · Oct 22, 2026

Same caffeine dose, different capsule, and only guarana produced a statistically significant boost in peak power. In a randomized crossover trial of 18 active men, guarana raised peak power output by 4.0% over placebo while anhydrous caffeine did not reach significance. But here's the catch: guarana didn't significantly beat caffeine head-to-head, and the differences between them were only descriptive. Here's what the numbers show, where the study falls short, and how to dose guarana by caffeine content if you want to try it.

A wide, editorial-style photograph of a professional track cyclist mid-stride on a velodrome's sloping wooden boards, captured from a low side angle with a shallow depth of field. The cyclist is in a sleek matte charcoal and soft coral skinsuit with an aerodynamic helmet, slightly motion-blurred, while the wood grain of the track glows in warm honey tones. Soft morning light streams through high arena windows, creating long, gentle beams and a subtle haze.

In the foreground, slightly out of focus, a minimalist still-life is arranged on a pale oak surface: a small amber glass supplement bottle with a clean cream label, two golden-orange softgel capsules resting beside it, and a ceramic cup of water. A small sprig of green leaves and a halved avocado add a fresh, natural touch, hinting at taking the supplement with fat. The composition places the still-life in the lower left third, with the cyclist blurring into the background on the right, creating a layered sense of depth.

The color palette is warm and refined: creamy off-white, honey wood, muted coral, soft amber, and touches of sage green. A thin, elegant overlay of subtle graph-like lines, such as two delicate rising curves in white, one slightly higher than the other, floats faintly over the upper right negative space, suggesting the small performance gap without any text or numbers. The overall look is clean, modern, and magazine-quality, like a wellness and sports science journal feature, with natural film-like grain, soft contrast, and generous negative space at the top for headline placement. Landscape 16:9 composition, calm and sophisticated mood, no text, no logos.

Olympic Hopefuls Took 300 mg Ubiquinol: The 2.5% Power Edge

BY DR. GYMBRO · Oct 20, 2026

In a double-blind study of 100 athletes preparing for the London 2012 Olympics, everyone got stronger on the bike, but the group taking 300 mg of ubiquinol improved more: +11% versus +8.5% on placebo. That roughly 2.5% edge was statistically significant, yet the study has caveats, including uncontrolled training and industry ties. We break down ubiquinol versus ubiquinone, what the numbers mean, and why the gap could matter to an elite cyclist but not to a recreational lifter. Plus: dosing, timing with fat, who should talk to a doctor first, and whether the cost is worth it.
