The urinary excretion of 4-pyridoxic acid (PIC), the principle
end-product of vitamin B₆ metabolism found in human urine, was
measured in two populations in whom altered vitamin B₆ metabolism
has been reported: in women who use oral contraceptives and in
mental retardates with and without Down's syndrome.
In the first...
Oral contraceptive (OC) users frequently have lower vitamin B₆
status than non-oral contraceptive (NOC) users. However, normal dietary

Therefore, 26 OC users and 25 NOC users, of college age, were compared
with respect to dietary intake of vitamin B₆ and blood...
The effect of oral contraceptives on urinary and plasma vitamin
B₆ as well as erythrocyte transaminase activities was investigated in
women. Five women who were taking oral contraceptives and four
who were not using these drugs served as subjects. They were
apparently healthy and free from any known metabolic disorder....
The effect of oral contraceptives on the urinary excretion of
several methionine metabolites was determined in women before and

between the ages of 20-29 years served as subjects: five had been
using a combination-type oral contraceptive for six months...
