Study for the Liquid Chromatography-mass Spectrometry (LC-MS/MS) Assessment of Oxidative DNA Damage in Relation to Antioxidant Usage

This study has been completed.

The purpose of this study is to evaluate the basis for the reported good effects of antioxidant supplementation. A blood test using Mass Spectrometry will measure DNA damage which is expected to decrease with antioxidant administration and therefore decrease the risk of cancer.

Condition Intervention
Dietary Supplement: 1 tablet composed of antioxidants and minerals

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label

Primary Outcome Measures:
  • To establish a base line level for 5 DNA modifications of White blood cells [ Time Frame: 2 years ]

Enrollment: 38
Study Start Date: January 2010
Study Completion Date: July 2012
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Antioxidant Supplements Dietary Supplement: 1 tablet composed of antioxidants and minerals
1 tablet daily

Detailed Description:
In this pilot study, the overall purpose is to establish the molecular basis for the hypothesis that oxidative stress is a risk factor for cancer. This will be achieved by establishing base line levels of oxidative DNA damage in a population of healthy individuals before and after taking antioxidant and mineral supplements for 8 weeks.
