Vitamin B1 - Thiamin - Thiamine.

Also know as Co-enzyme thiamine pyrophosphate (TPP), Vitamin B1 is needed in regular supply by the body and its odor and flavour are similar to those of yeast. It is needed by the Central Nervous System the Gasto-intestinal system and the cardiovascular system. It helps convert carbohydrate to fat for storage for potential energy and plays a role in glucose metabolism. It is thought that adequate amounts of Vit B1 may help reduce the progression of atherosclerosis by preventing the accumulation of fatty deposits in the arteries, thus it is also helpful to the heart.
