Previous. In the presence of insulin, the micronutrient combination tested further enhanced this effect up to 1445% over controls. After adjustment for potentially confounding variables (e.g., age, race, BMI, serum lipids, and blood pressure), the use of MVMs for more than 3 years was associated with a substantial 44% reduction in CVD mortality rates among women, but not men.
