Dietary intake of omega-3 fatty acids and folic acid shows promise for cardiovascular disease prevention. However, vitamin E supplementation has yielded disappointing results in clinical trials despite its antioxidant properties.

Area of Science:

  • Nutrition Science
  • Cardiovascular Health
  • Dietary Supplements

Background:

  • Epidemiological studies link micronutrient intake (omega-3 fatty acids, folic acid, vitamin E) to reduced cardiovascular disease (CVD) incidence.
  • This has fueled a large market for vitamin supplements, often used as self-medication without medical guidance.
  • Recent trials investigate the role of these micronutrients in CVD prevention.

Purpose of the Study:

  • To evaluate the efficacy of omega-3 fatty acids (FA), folic acid, and vitamin E in cardiovascular disease prevention.
  • To analyze the impact of dietary intake versus supplementation of these micronutrients.
  • To clarify the clinical outcomes associated with these supplements.

Main Methods:

  • Review of large epidemiological studies and recent prospective clinical trials.

  • Analysis of mechanisms of action for omega-3 FA, folic acid, and vitamin E on cellular metabolism and cardiovascular markers.
  • Comparison of dietary intake effects versus supplementation effects.

    • Main Results:

    • Omega-3 fatty acids demonstrate efficacy in secondary CVD prevention, impacting cell metabolism.
    • Folic acid intake, from diet or supplements, positively influences cardiovascular prevention, acting as an antioxidant and reducing homocysteine.
    • Vitamin E supplementation results have been largely disappointing, despite its known antioxidant and protective functions.

    Conclusions:

    • Omega-3 fatty acids and folic acid show potential benefits for cardiovascular health, particularly through dietary intake and in secondary prevention.
    • Vitamin E supplementation's clinical efficacy for cardiovascular prevention remains uncertain and contrasts with its demonstrated biological properties.
    • Further research is needed to clarify optimal strategies for micronutrient supplementation in cardiovascular disease management.
