Goals
Thiamine is absolutely fundamental to metabolism, especially the conversion of carbohydrates into energy (glucose metabolism) through the Krebs cycle. It is directly involved in many critical metabolic pathways, making it essential for energy conversion.
Thiamine is a coenzyme crucial for carbohydrate metabolism, directly converting food into energy. Supplementation can help ensure efficient energy production, especially for those with insufficient dietary intake or increased demands.
Thiamine is essential for nerve function and neurotransmitter synthesis, directly supporting healthy brain function. Adequate levels are vital for cognitive processes and preventing neurological issues due to its role in glucose metabolism in the brain.
