This thesis aims to explore the intricate interactions, reactions, and counteractions of vitamins within the human body. Vitamins are essential organic compounds required in small quantities for the proper functioning of various physiological processes. While each vitamin plays a unique role, their interdependencies and potential for interactions are crucial to understand. This thesis examines the mechanisms behind vitamin interactions, including absorption, metabolism, and potential antagonistic or synergistic effects. By delving into these complexities, this research seeks to contribute to a comprehensive understanding of how vitamins interact, react, and counteract with each other, and their implications for human health
