Vitamin B1 (Thiamine)


This blood test measures Vitamin B1 (Thiamine) levels. Vitamin B1 (Thiamine) was the first B Vitamin discovered. All of the water-soluble B vitamins work as a team to help promote healthy nerves, skin, eyes, hair, liver, muscle tone and cardiovascular function.

Vitamin B1 is a water-soluble vitamin and acts as a coenzyme and is essential for a number of reactions in metabolism. Vitamin B1 is involved in many body functions including the nervous system, muscle function, metabolism and digestion. Because Vitamin B1 is water soluble and very little is stored in the body, depletion of this vitamin can occur rapidly. Vitamin B1 metabolism is extremely complex and is the focus of continuing research. Vitamin B1 is an essential nutrient as it plays a vital role in carbohydrate, protein and lipid metabolism. Thiamine deficiency can develop after only one month of a thiamine-free diet. Mild thiamine deficiency occurs in pregnant women (due to their increased requirement), diabetics, the elderly and in malabsorption syndromes. Severe thiamine deficiency is a disorder called beriberi.

Test Preparation For Optimal Results:
