Vitamin D

When it comes to the effect of increasing the body's resistance, vitamin C is the name that first comes to mind. However, recent studies show that vitamin D has an important effect in strengthening the immune system, especially infections.

Vitamin D is an essential nutrient for the functioning of the immune system. It plays an important role in promoting the immune response by enhancing the function of T cells and macrophages to protect your body from pathogens. Besides, it also has anti-inflammatory, immunomodulatory properties and the ability to activate the immune system's defenses. The most concentrated dietary source of vitamin D is fish liver oil, which is also known for its omega-3 fatty acid concentration. The other significant sources are fish, mushrooms, fortified milk, and orange juice.
