Answer

Vitamin B-1 (ie, thiamine) is found in organ meats, yeast, eggs, and green, leafy vegetables. Vitamin B-1 supplements usually contain 50-500 mg of vitamin B-1 per tablet. This vitamin is a cofactor for pyruvate dehydrogenase in the Krebs cycle. The RDA is 1.5 mg (0.7 mg for children aged 1-4 y).
