摘要
Berg 博士讲解了维生素 B1(硫胺素)在运动中能量产生方面的作用,重点介绍了其在线粒体功能和细胞呼吸中的参与机制。他建议在锻炼前补充 B1 以提升能量和耐力,同时建议将其作为 B 族复合维生素的一部分一起服用,以避免营养失衡。
核心要点
- Vitamin B1(硫胺素) 直接参与线粒体能量产生,在与代谢相关的五种不同酶中发挥作用
- B1 帮助将食物转化为 ATP,即人体主要的能量货币
- 它还有助于清除体内的代谢废物,如乳酸和氨
- 摄入的碳水化合物越多,身体所需的 B1 就越多
- 遵循 ketogenic diet 的人对 B1 的需求较少,但仍建议补充
- B1 被认为是一种抗疲劳营养素,能够在体力活动中支持耐力表现
- 长期单独服用 B1 可能导致其他 B 族维生素缺乏——应始终搭配 B 族复合维生素一同服用
- 营养酵母是推荐的天然 B 族维生素来源
详细内容
B1 如何支持能量产生
Vitamin B1(硫胺素)是cellular respiration(细胞呼吸)的核心参与者——细胞呼吸是指人体利用氧气将食物转化为可用能量的过程。它在此过程中支持五种关键酶的功能:
- 分解食物中的碳原子,以 ATP 的形式释放能量
- 清除乳酸和氨等代谢副产物,这些物质在运动中积累并导致疲劳
B1 与碳水化合物摄入
碳水化合物的摄入量与 B1 的需求量之间存在直接关系。高碳水化合物饮食需要更多 B1 来处理额外的葡萄糖。遵循 ketogenic diet 的人由于碳水化合物代谢减少,对 B1 的需求较低,但仍建议补充,以获得其抗疲劳功效。
运动前补充方案
Berg 博士建议在运动前约 30 分钟服用 B1,以便在锻炼过程中感受到能量水平和耐力的显著提升。
补充建议
- 将 B1 作为 B-complex(B 族复合维生素)的一部分服用,而非单独服用
- 长期单独服用 B1 可能导致其他 B 族维生素耗竭
- 营养酵母被推荐为全食物来源,能够天然提供完整的 B 族维生素复合物及 B1
- 在复合维生素的基础上,可额外单独补充 B1,以进一步提升运动表现

Summary
Dr. Berg explains the role of Vitamin B1 (thiamine) in energy production during exercise, highlighting its involvement in mitochondrial function and cellular respiration. He recommends supplementing with B1 before workouts to boost energy and endurance, while also advising it be taken as part of a B-complex to avoid imbalances.
Key Takeaways
- Vitamin B1 (thiamine) is directly involved in mitochondrial energy production, playing a role in five different enzymes related to metabolism
- B1 helps convert food into ATP, the body’s primary energy currency
- It also helps clear metabolic waste products like lactate and ammonium from the body
- The more carbohydrates you consume, the more B1 your body requires
- People on a ketogenic diet need less B1, but supplementation is still recommended
- B1 is considered an anti-fatigue nutrient that supports endurance during physical activity
- Taking B1 in isolation long-term may cause deficiencies in other B vitamins — always pair with a B-complex
- Nutritional yeast is a recommended natural source of B vitamins
Details
How B1 Supports Energy Production
Vitamin B1 (thiamine) is centrally involved in cellular respiration — the process by which the body uses oxygen to convert food into usable energy. It supports five key enzymes in this process:
- Breaking down carbon atoms from food to release energy as ATP
- Clearing metabolic byproducts such as lactate and ammonium, which accumulate during exercise and contribute to fatigue
B1 and Carbohydrate Intake
There is a direct relationship between carbohydrate consumption and B1 demand. Higher carb diets require more B1 to process the additional glucose. Those following a ketogenic diet have lower B1 requirements due to reduced carbohydrate metabolism, though supplementation is still advised for its anti-fatigue benefits.
Pre-Workout Protocol
Dr. Berg recommends taking B1 approximately 30 minutes before exercise to experience a noticeable increase in energy levels and endurance during the workout.
Supplementation Recommendations
- Take B1 as part of a B-complex rather than in isolation
- Long-term use of isolated B1 can deplete other B vitamins
- Nutritional yeast is highlighted as a whole-food source that naturally provides the full B-vitamin complex alongside B1
- Additional standalone B1 can be taken on top of the complex for enhanced workout performance
