Mild allergic reactions such as rash or itching

How Thiamine works
Thiamine is a crucial B-complex vitamin.
It plays a critical role as a coenzyme in carbohydrate metabolism. It is essential for the conversion of pyruvate to acetyl-CoA in the Krebs cycle, which is crucial for energy production. Thiamine also supports nerve function by aiding in the synthesis of neurotransmitters.
