Vitamin E food supplement; 400 mg in form of oral capsules once daily for 14 days.
Adherence will be monitored by drug capsules return.

Outcomes
Primary outcome [1] 295389 0
The metabolomic profile change after fortnight vitamin E food suplement. This is one composite outcome.
Endogenous metabolome will be obtained using ultra-performance liquid chromatography electrospray ionization time-of-flight mass spectrometry and data analyzed using multivariate analysis tools.
Timepoint [1] 295389 0
Baseline, and at 7th and 14th day after vitamin E food suplement.
Secondary outcome [1] 315494 0
Verify the effect of pregnane xenobiotic receptor (PXR) polymorphisms on potential changes in metabolomics induced by vitamin E food suplement. PXR polymorhism will be detected using PCR methods.
Timepoint [1] 315494 0
Blood samples for PXR polymorphisms identification will be taken at baseline.
