Gebhardt, P. (2021), Micronutrients for the immune system: vitamin A, vitamin D, magnesium and zinc. Wellness Foods and Supplements, (3), 29-33.

Phytic acid contained in plant-based foods forms insoluble complexes with zinc and inhibits the uptake of the trace element in the small intestine. The phytate content of a meal correlates inversely with the absorption of the contained zinc.

The immune system protects us from pathogens such as bacteria, viruses and fungi. Various micronutrients are of particular importance for the functioning of our body’s defences. Vitamin A, zinc, vitamin D and magnesium are essential for the normal function of the immune system. However, there is often insufficient intake with food, so that supplementation can be useful.
