Magnesium absorption mainly occurs in the small intestine and, to a lesser extent, in the large intestine. The process involves both passive diffusion, depending on the concentration gradient, and active transport, which is energy-dependent and regulated by numerous factors, including the presence of specific transport proteins. Generally, when dietary intake is low, the body increases the efficiency of magnesium absorption, and vice versa.


Factors Affecting Magnesium Absorption


Amount of Dietary Magnesium: High doses of magnesium at one time can lead to decreased absorption efficiency because the intestines can only absorb a certain amount efficiently at any given point.


Form of Magnesium: The bioavailability of magnesium, meaning how well it can be absorbed and utilized by the body, varies depending on its form. For instance, magnesium in the form of citrate, lactate, or chloride is generally better absorbed than magnesium oxide or sulphate.


Phytates and Fibre: High amounts of phytates found in legumes, nuts, seeds, and whole grains can bind magnesium, making it less available for absorption. Similarly, excessive fibre can slightly inhibit magnesium absorption, though fibre-rich foods are still an important part of a healthy vegan diet.


Other Nutrients: Certain nutrients can enhance magnesium absorption, while others might inhibit it. Vitamin D, for example, can improve magnesium absorption, whereas excess dietary fats might coat magnesium particles and inhibit their absorption.


Gastrointestinal Health: The overall health of the gastrointestinal tract plays a crucial role in magnesium absorption. Conditions such as Crohn's disease, celiac disease, or chronic diarrhoea can lead to reduced absorption and should be managed accordingly.


Age and Genetic Factors: It’s noted that magnesium absorption decreases with age. Moreover, genetic variations might affect the expression of transport proteins, influencing individual magnesium absorption rates.


Enhancing Absorption


Given these factors, improving magnesium absorption involves a multifaceted approach including dietary considerations, like consuming magnesium-rich foods throughout the day instead of in a single meal, pairing them appropriately with other foods to enhance bioavailability, and addressing any underlying gastrointestinal issues.


Understanding the complexities of magnesium absorption underscores the importance of not just focusing on magnesium intake but also on adopting dietary and lifestyle practices that support optimal absorption. This approach ensures that the body can efficiently utilize magnesium, promoting better health and well-being for those following a vegan lifestyle.
