A wide, editorial-style flat lay photographed from above on a pale warm-gray linen surface in soft natural window light. At the center, a small open amber glass jar tips gently onto its side, spilling a few cream-colored capsules across the fabric. Next to the jar sits a loose arrangement of fresh mushrooms: a cluster of golden-tan reishi with glossy, lacquered caps, a few slender white enoki stems, a halved shiitake showing its pale gills, and a curl of turkey tail with concentric bands of rust, cream, and charcoal. A small wooden scoop holds a pile of fine beige mushroom powder.

On the left third of the frame, a matte black sports watch with a minimal face lies beside a folded sage-green running shirt and a pair of lightweight off-white running shoes, hinting at athletic training without showing a person. A slim white notebook with a single pencil rests nearby, open to a blank page with a faint hand-drawn line graph trending upward, in thin graphite strokes.

On the right side, a pair of clear glass beakers and a single small petri dish with a soft amber-tinted liquid add a subtle laboratory note, kept calm and organic. A single sprig of dried herbs and a few scattered oat-colored grains add texture.

The palette is earthy and refined: oatmeal, soft sage, terracotta, warm amber, and charcoal accents against the muted neutral background. Shadows are soft and diffused, with a gentle highlight on the glass and the glossy reishi cap. The composition leaves generous negative space in the upper right for a headline overlay. Shallow depth of field blurs the edges slightly, while the central mushrooms and capsules stay crisp. The overall feel is modern, clean, and trendy, like a wellness and science magazine cover, with tactile natural textures, minimal styling, and a quiet sense of curiosity and skepticism.

蘑菇胶囊提升 VO2max 14.8%——但其中有个大问题

BY DR. GYMBRO · 2026年10月29日

一颗蘑菇胶囊、40 天、VO2max 提升了 14.8%，听起来几乎像是天方夜谭。最新发表在《Antioxidants》上的研究称，50 名年轻男性运动员每天摄入 320 mg 含 β‑葡聚糖的多菌种提取物，最大摄氧量从 46.26 mL/kg/min 上升至 53.12 mL/kg/min。值得注意的是，这项研究没有安慰剂组、也未采用随机化和双盲设计，受试者在实验期间仍保持常规训练。细胞实验虽在大鼠心肌细胞上展示了低氧相关的作用机制，但仅是单一成分的试验，并未直接对应胶囊的整体效果。下面我们来看看这项研究到底说明了什么、不能说明什么，以及哪些人应当持谨慎态度。

HMB在2026年最新试验中提升心肺适能，而非力量

BY DR. GYMBRO · 2026年10月19日

HMB常被宣传为帮助维持肌肉、提升力量的补剂，但最新的三盲试验却显示了不同的效果。在90名男性受试者中，使用高剂量、依据无脂体重个性化的液体HMB自由酸（每日每公斤无脂体重90 mg）并配合高强度功能训练，显著提高了VO₂max及阈值指标，安慰剂组未见变化。该效应在已有训练经验的男性中最为明显，而等长腿部力量并未提升。下面将介绍剂量计算、与常规3 g剂量的比较，以及可能受益的人群。

A wide, editorial-style flat lay photographed from above on a pale warm-gray stone countertop in soft morning window light. On the left, a small matte white ceramic bowl holds fine white arginine powder, with a wooden scoop resting beside it. At the center, two halved oranges and one whole lemon in saturated citrus tones, with a few glossy droplets of water on the cut surfaces, to suggest vitamin C. On the right, three slim amber glass capsule bottles with minimal cream labels and no legible text stand in a loose row, with a few white capsules spilling out. A single chrome dumbbell handle enters the frame from the upper right corner, partly cropped, its cool metallic sheen contrasting with the warm fruit. A sprig of green rosemary and a folded linen napkin in oatmeal beige add texture. Long soft shadows fall to the left. The palette is warm cream, sunny orange, soft yellow, and muted sage, with a few crisp accents of steel gray. The composition is airy and uncluttered, with generous negative space in the upper left for a title overlay. It has a shallow depth of field, a crisp foreground, and a faintly blurred background. The look is clean, contemporary, and wellness-magazine, like a premium health and fitness journal cover, with natural grain, high-end product photography quality, and a calm, fresh, trustworthy mood.

3克精氨酸 + 500毫克维生素C：举重者睾酮提升 26%

BY DR. GYMBRO · 2026年10月18日

长期以来，精氨酸常被包装成一氧化氮（NO）助推剂，但多数受控研究并未证实其效果。最新的一项随机对照试验将精氨酸与维生素C同服，结果出乎意料。50 名男性健美选手在 45 天内每日摄入 3 克左旋精氨酸（分三次）+ 500 毫克维生素C，血清睾酮和最大摄氧量（VO₂max）均显著高于安慰剂组，体脂也有所下降。生长激素、皮质醇及氮平衡未出现显著差异。该低成本叠加方案值得关注，但仅来源于一项小样本试验，睾酮提升并不等同于肌肉增长。
