Vitamin A and vitamin E in human blood

Abstract

In the first paper of this series (Leitner, Moore & Sharman, 1960) we reported values for the levels of vitamin A and carotenoids found in blood collected between 1948 and 1957 from British men and women. During 1952-7 an investigation, partly overlapping with that on vitamin A, was made on vitamin E. A preliminary paper, based on some of our earlier results, has already been published The present communication gives our results in full.
