ABSTRACT
If status is adequate, added TPP has minimal effect on the AC. If status is inadequate, the AC increases. Marginal deficiency is indicated at AC levels of 1.20-1.25.2 Inadequate intake of thiamin, problems with absorption and transport, and decrease in TPP synthesis, all can lead to deficiency.6 In developed countries, severe thiamin deficiency is rare; however, marginal deficiency is more frequently documented.
