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.

Creatine + beta‑alanine: de vermeende stack‑bonus die onderzoekers niet vonden

BY DR. GYMBRO · 28 okt 2026

De combinatie van creatine en beta‑alanine wordt vaak aangeprijst als een krachtig duo voor sportprestaties, maar een recente netwerk‑meta‑analyse van 52 gerandomiseerde onderzoeken vond geen synergie tussen de twee. Creatine alleen verbeterde significant sprint‑, sprong‑, herhaalde‑sprint‑ en bovenlichaam‑uithoudingsvermogen vergeleken met placebo. De effecten van beta‑alanine waren niet‑significant of alleen in bepaalde contexten aanwezig, en de combinatie leverde geen extra voordeel op ten opzichte van creatine alleen. Hieronder lees je wat de onderzoekers deden, welke beperkingen er zijn en wat dit betekent voor je supplementenbudget.

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.

Bakpoeder en sprints: de dosis die placebo in elke test verslaat

BY DR. GYMBRO · 27 okt 2026

Een nieuwe gerandomiseerde studie onder basketbalspelers liet zien dat het toevoegen van natriumbicarbonaat (bakpoeder) aan vier weken sprint‑intervaltraining betere sprong‑ en sprintresultaten, wendbaarheid, Yo‑Yo‑afstand en Wingate‑vermogen oplevert dan een placebo. De hogere dosis van 0,45 g/kg overtrof de 0,3 g/kg op elke gemeten variabele. Het is een goedkoop, aantrekkelijk supplement voor teamsport‑atleten, maar maagklachten vormen een aandachtspunt. Bovendien is de studie klein, van korte duur en alleen bij mannen uitgevoerd. Hieronder vind je de doseringsberekeningen, tips om gastro‑intestinale klachten te vermijden en voor wie dit echt relevant is.
