Abstract: A study of the pharmacokinetic profile (oral absorption and renal
excretion) of inositol hexaphosphate or phytate (IP_6) is
presented. Seven healthy volunteers were following a IP_6
poor diet (IP_6PD) in a first period, and on
IP_6 normal diet (IP_6ND) in a second
one. When following the IP_6PD they become deficient in
IP_6, the basal levels found in plasma (0.07±
0.01 mg/L) being clearly lower than those found when
IP_6ND was consumed (0.26± 0.03 mg/L).
During the restriction period the maximum concentration in plasma were obtained
4 h after the ingestion of a single dose of IP_6, observing
almost the same renal excretion profiles for the three different comercial
sources and doses. After the IP_6 restriction period,
volunteers were on IP_6ND, reaching normal plasma and
urinary IP_6 values in 16 days. Thus, the normal plasma and
urinary concentrations, can be obtained either by comsumption of a
IP_6ND taking a long time or in a short period by
IP_6 supplements.
