Compounds Influencing Magnesium Absorption

Magnesium (Mg2+) is the fourth most abundant cation in the body and the second most common at the Intracellular Level (IC). In humans, it is involved in the activity of hundreds of enzymes, covering approximately 80% of metabolic functions. Homeostasis is achieved by a balance between ingestion, excretion, and reservoir. According to data from Health and Nutrition Organizations, an important percentage of individuals consume less than the Dietary Reference Intake (DRI) of magnesium from food. In the intestine, there are several inhibitors and enhancers of magnesium absorption. This includes physicochemical and dietary factors. This narrative review aims to evaluate the compounds influencing Mg2+ absorption. These factors can be considered when determining Dietary Reference Intakes (DRIs) for the population to prevent deficiency and non-communicable diseases. The recommendations aim to increase fruit and vegetable consumption, as they are mineral-rich and alkalinizing foods.
