Thiamin (vitamin B1) is needed to process carbohydrates- fat- and protein. Every cell of the body requires vitamin B1 to form ATP—the fuel the body runs on. Nerve cells require vitamin B1 in order to function normally. Deficiency is most commonly found in alcoholics- people with malabsorption conditions- and those eating a very poor diet. Sona Thiamin (Vitamin B1) is made of the highest quality containing 100mg of thiamin per tablet.
