Vitamin B1, also known as thiamine, plays a crucial role in maintaining optimal health, particularly for your nervous system and heart function. This essential nutrient helps convert food into energy and supports various vital bodily processes. Understanding its importance, recognizing deficiency symptoms, and knowing how to maintain healthy levels can significantly impact your overall well-being.
While severe vitamin B1 deficiency is relatively rare in developed countries, certain groups remain at risk, and mild deficiency can occur without obvious immediate symptoms. This comprehensive guide explores everything you need to know about vitamin B1, from identifying deficiency signs to ensuring adequate intake through diet and supplementation.
