This review explores updated vitamin functions from a biochemical viewpoint, highlighting roles in oxidant defense, cellular communication, and disease prevention through supplementation. It emphasizes the shift in nutrition science towards understanding vitamin status and health interactions.

Area of Science:

  • Biochemistry
  • Nutritional Science
  • Molecular Biology

Background:

  • Vitamin function research has evolved significantly over the past decade.
  • Nutrition paradigms have shifted towards disease prevention and the role of supplements.
  • Basic biochemical and physiological mechanisms are now understood for vitamin-health interactions.

Purpose of the Study:

  • To review newer aspects of vitamin function from a biochemical perspective.
  • To explore six key themes of vitamin function and their implications for health.
  • To highlight the evolving understanding of vitamin supplementation in disease prevention.

Main Methods:

  • Literature review focusing on biochemical and physiological mechanisms.
  • Synthesis of current research on specific vitamins and their functions.
