Vitamin B1 is found in high concentrations in which part of the body?

Vitamin B1, also known as thiamine, is predominantly concentrated in skeletal muscle. This is primarily due to the role that thiamine plays in energy metabolism and muscle function. Skeletal muscles require adequate amounts of thiamine to efficiently convert carbohydrates into energy, particularly during physical activity.

Thiamine is involved in several key metabolic pathways, including the conversion of pyruvate to acetyl-CoA, which is crucial for energy production in muscle tissues. Since skeletal muscles are active and require a constant supply of energy, they store higher amounts of thiamine compared to other organs.

While the liver, heart, and brain also use thiamine and play important roles in its utilization, the skeletal muscle is where the highest concentrations are found, supporting its energy needs during movement and exercise.
