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.

Creatina + beta‑alanina: el supuesto beneficio del stack que los investigadores no hallaron

BY DR. GYMBRO · 28 oct 2026

El combo de creatina y beta‑alanina se promociona como la pareja perfecta para el rendimiento, pero un meta‑análisis de redes con 52 ensayos aleatorizados no encontró sinergia entre ambos. La creatina sola mejoró de forma significativa los resultados de sprint, salto, sprint repetido y resistencia muscular de la parte superior frente al placebo. Los efectos de la beta‑alanina fueron no significativos o dependientes del contexto, y la combinación no aportó nada adicional a la creatina. A continuación, analizamos qué hizo el estudio, sus limitaciones y qué implica para tu presupuesto de suplementos.

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.

Bicarbonato de sodio + sprints: la dosis que superó al placebo en todas las pruebas

BY DR. GYMBRO · 27 oct 2026

Un nuevo ensayo aleatorio en jugadores de baloncesto descubrió que añadir bicarbonato de sodio (bicarbonato de hornear) a cuatro semanas de entrenamiento en intervalos de sprint superó al placebo en salto, sprint, agilidad, distancia Yo‑Yo y potencia Wingate. La dosis más alta (0,45 g/kg) superó a la de 0,30 g/kg en todas las medidas. Esto lo convierte en un suplemento barato y tentador para deportistas de equipos, aunque el estómago puede ser un problema y el estudio es pequeño, corto y solo con hombres. Aquí tienes el cálculo de la dosis, los trucos para evitar molestias gastrointestinales y a quién le puede interesar realmente.
