How much Vitamin B1 (Thiamine) should I take daily?

Introduction

Vitamin B1, also known as thiamine, is an essential nutrient that plays a crucial role in energy metabolism and the normal function of the nervous system, visual system, and heart. Determining the appropriate daily intake of thiamine is important for maintaining health and preventing deficiency.

Key Insights from Research Papers

High-dose thiamine supplementation (100 mg/day) may aid in preventing or accelerating recovery from exercise-induced fatigue in male athletes with normal blood thiamine levels.
A significantly higher dose of thiamine (300 mg/day) can lower blood glucose levels during and after physical activity, suggesting a potential role in managing exercise-induced fatigue.
For infants, a thiamine intake between 100 to 150 units per day may be considered optimal for development, with intakes above this range resulting in rapid excretion of excess vitamin in the urine.
The daily requirement for vitamin B1 is related to calorie intake, with a recommendation of 0.4 mg of thiamine for every 1000 kcal consumed.

Conclusion

The daily intake of thiamine varies depending on age, physical activity, and calorie consumption. For athletes and active individuals, higher doses ranging from 100 mg to 300 mg per day may be beneficial in managing fatigue related to exercise. Infants may require between 100 to 150 units of thiamine per day for optimal development. In general, the daily needs for vitamin B1 should align with caloric intake, at a rate of 0.4 mg per 1000 kcal. It is important to tailor thiamine intake to individual needs and circumstances.
