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 プロバイオティック：エリート選手が1週間で持久時間を33秒伸長

BY DR. GYMBRO · 2026年10月17日

マルチ株プロバイオティックSLAB51を1週間摂取したエリート選手は、プラセボ時と比べてトレッドミルテストで約33秒長く走り続けました。単回投与では効果は認められず、VO2maxにも変化は見られませんでした。運動前の抗酸化酵素SOD活性が上昇したことも報告されています。本稿では研究デザインや数値を解説し、サンプル数の少なさや対象が限定的である点についても触れます。

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.

4日間のアスタキサンチン投与でサイクリングの疲労限界時間が72分から85分に伸長―小規模試験の結果

BY DR. GYMBRO · 2026年10月15日

28 mg/日を4日間摂取したところ、サイクリングの疲労限界時間が約72分から85分へと約18％伸びました。同じプロトコルでは、激しい75％VO2maxのライド後に筋肉損傷マーカー（CK・LDH）と脂質過酸化（MDA）の上昇が抑えられました。炎症マーカーやエネルギー利用は変化せず、メカニズムはまだ不明です。投与量は市販のソフトジェルが提供する量を上回っており、対象は10名の若年男性だけでした。以下に数値の詳細とエビデンスの限界を示します。
