Vitamins and minerals, owing to their varied structures, interact with each other and with other constituents to decrease (antagonism) or improve the absorption (collaboration) of a specific vitamin or element. The principles of collaboration and antagonism should be meticulously observed when supplementing with multiple individual substances, designing multivitamins, and creating a healthy diet plan. It is beneficial to comprehend the techniques for combining vitamins and minerals to enhance their mutual absorption.
Biological Availability: Nutrient Absorption Mechanisms and Determinants of Their Efficient Utilization by the Human Body
Biological availability constitutes a multifaceted physiological process wherein the terminal metabolites derived from the digestion of macronutrients—including polysaccharides, proteins, and triglycerides—as well as micronutrients such as water-soluble and fat-soluble vitamins and electrolytes undergo selective absorption via active transport and passive diffusion across the mucosal enterocytes of the small intestine. This is succeeded by systemic distribution through the circulatory and lymphatic networks. The extent of bioavailability, encompassing both quantitative and qualitative dimensions of absorption, ultimately dictates the proportion of nutrients that reach target tissues in a metabolically or therapeutically active form. Disruptions to this process may arise from several determinants, including the suboptimal chemical specification of a given compound, the presence of competitive inhibitors that obstruct transporter receptors, deficiencies in cofactors that facilitate cellular membrane permeation, and interactions with catabolic enzymes or antivitamins that abrogates the biological potency of vitamin derivatives.
