The Role of Immunity in Human Body
Immunity is the ability of the body's immune system to protect itself, mainly referring to the body's ability to resist infections such as bacteria or viruses. The immune system is a system in which many links work together, including immune organs, immune cells and immune molecules, and they play different roles in different links.
The immune system has both preventive and repair functions. In a healthy state, it is always on combat readiness, preventing disease and knowing exactly when, where and how to take appropriate action to destroy invading substances without harming other cells in the body.
Therefore, keeping the immune system stable is vital to our health. If you experience frequent fatigue, constant colds, gastrointestinal problems, and wound infections, these symptoms may indicate a weakened immune system. Ensuring good lifestyle habits and a healthy state of mind are the most effective ways to boost immunity, but for many people it's not easy. Fortunately, proper nutraceuticals are convenient candidates for helping you prevent disease and boost your overall immune system.
Nutraceuticals For Immune Function
Antiviral nutrition
There are dynamic interactions between nutraceuticals and the immune system, including direct antibacterial effects, enhanced antiviral immune responses, and immune modulation that prevents tissue damage caused by the immune response itself. Several nutraceuticals with immunomodulatory properties (including vitamin D, vitamin A, zinc, lactoferrin, polyphenols, and coenzymes Q, etc.) and their main antiviral effects are summarized as below. [1]
Plant-based nutrition
Numerous studies have confirmed that some medicinal plants and phytochemicals have the ability to modulate the function of the immune system. The figure below shows some examples of bioactive components obtained from immunomodulatory plants and their effects on immune function. Several phytochemicals, especially alkaloids, phenols, glycoproteins and saponins, have anti-inflammatory and immunomodulatory properties. In addition, as possible immunomodulators, terpenoids, polysaccharides and fatty acids can be further applied in immune diseases. [2]
Nutritional regulation of immune aging
Immune cell dysfunction with age is multifaceted and uniquely attributed to independent processes of immune and cellular senescence. Three different sources of bioactive components, namely phytochemicals, probiotics and omega-3-fatty acids, showed promising anti-immune and anti-cellular senescence potential in immune cells.[3]

Nutraceuticals as immune-stimulating therapy to fight COVID-19
The immune system is key to reducing the severity of COVID-19, and through its regulation, it has the potential to save lives. In a recent brief exchange, the authors noted that oral supplements, due to their ability to stimulate and modulate these cells, may help the immune system produce appropriate adaptive answers. They summarize how different molecules regulate cytokines, white blood cells, and how they interact to prevent viral replication and fight Sars-CoV2 infection. [4]
