Vitamin B1 (thiamine), which is one of the B vitamins, has significant positive effects on human health. It contributes to the normal functioning of the heart and is also involved in the complex processes of energy conversion in the body. In addition, it affects the proper functioning of the nervous system and psychological state. And since humans cannot store vitamin B1, it is important to ensure regular intake.
Frequently Asked Questions
Vitamin B1 is absolutely essential for carbohydrate metabolism. Its main job is to convert carbohydrates from your diet into ATP molecules, which is pure cellular energy. Furthermore, it is absolutely crucial for the proper functioning of the nervous system and the heart, making it a foundational vitamin for any hard-training athlete.
Absolutely yes, that is the golden rule of thiamin! The more carbohydrates you consume in your diet (for example, during "carb cycling" or a heavy bulking phase), the more Vitamin B1 your body consumes to process them. If you are deficient, your body cannot effectively use carbs as fuel, leading to severe fatigue and a drop in performance.
Thiamin is involved in the formation of myelin, which is the protective sheath around nerve fibers. This ensures the fast and smooth transmission of nerve impulses from the brain to the muscles. For you, this means better muscle coordination, faster reaction times, and a significantly lower feeling of mental and physical exhaustion after a demanding day.
You don't need to worry at all. Vitamin B1 is water-soluble, meaning the body cannot store it in long-term reserves. If you take a higher dose than your body can currently use, any excess will be completely safely and naturally excreted in the urine. Therefore, an overdose from regular dietary supplements is virtually impossible.
Since its main task is energy processing, it is absolutely ideal to take it in the morning with breakfast or with a carbohydrate-rich pre-workout meal (e.g., oatmeal, rice). This ensures that the food you consume is efficiently converted into the energy you will use during an intense workout.
