The immune system is an incredibly complex network of organs, tissues, glands, and cells that find and respond to harmful foreign invaders like viruses and bacteria, which can cause disease. The immune system relies on various micronutrients, such vitamin A, vitamin C, vitamin D, vitamin E, selenium, beta-carotene, iron, and zinc, for optimal functioning. Deficiencies in these and other phytonutrients can lead to increased risk for infection and longer recovery periods.
Ideally, we would get all the essential immune-boosting vitamins and minerals we need by eating nutritious foods. However, it can be difficult to maintain a balanced diet for many reasons. Even if you consume a nutrient-rich diet, industrial farming practices have eroded the microbiome of the soil our food is grown in and with it the nutritional value of most food products. As a result, it's critical to take targeted supplements that support your immune system.
