Area of Science:

  • Nutritional Biochemistry
  • Cardiovascular Health
  • Dietary Supplements

Background:

  • Multivitamin supplements are widely marketed for disease risk modification.
  • Scientific validation of many commercial supplements is limited.
  • This study investigates a specific 24-ingredient multivitamin formula.

Purpose of the Study:

  • To evaluate the effects of a 24-ingredient multivitamin on specific biomarkers.
  • To assess changes in vitamin concentrations, homocysteine, lipids, and LDL oxidation.
  • To provide scientific evidence for the efficacy of a multivitamin formula.

Main Methods:

  • An open-label pilot study involving 150 subjects.
  • Measurements of vitamin levels, homocysteine, lipids, and LDL oxidation at baseline, 12, and 24 weeks.

  • Statistical analysis to determine significant time effects and correlations.

    • Main Results:

    • Significant increases in vitamin B6, B12, and folic acid concentrations observed.
    • Significant decrease in homocysteine levels noted during the treatment period.
    • Reduced LDL oxidation rate and increased LDL oxidation lag time, indicating antioxidant effects.

    Conclusions:

    • A multi-ingredient vitamin formula demonstrated measurable effects on homocysteine and LDL oxidation.
    • The formula possesses antioxidant properties with positive impacts on key biomarkers.
    • Further research can explore the clinical implications of these findings.
