Vitamin D and Zinc are the two most important things for the immune system.
The study below explains why vitamin D is so important to the immune system.
Interferons are the “scouts and messengers” that tell the immune system, “Incoming invaders! Time to send out the troops!” As you see from that study they need Vitamin D to function.
These results suggest a mechanism in which vitamin D is required for acquired immunity to overcome the ability of intracellular pathogens to evade macrophage-mediated antimicrobial responses.
The present findings underscore the importance of adequate amounts of vitamin D in all human populations for sustaining both innate and acquired immunity against infection.

Zinc is an important anti-viral.
This review focuses on the role of zinc as an essential micronutrient that is required to mount an effective antiviral response. Although zinc possesses direct antiviral properties (e.g. influenza), it is also critical in generating both innate and acquired (humoral) antiviral responses.
Zinc is an essential trace element that is crucial for growth, development, and the maintenance of immune function. Its influence reaches all organs and cell types, representing an integral component of approximately 10% of the human proteome, and encompassing hundreds of key enzymes and transcription factors.
Zinc deficiency is strikingly common, affecting up to a quarter of the population in developing countries, but also affecting distinct populations in the developed world as a result of lifestyle, age, and disease-mediated factors. Consequently, zinc status is a critical factor that can influence antiviral immunity, particularly as zinc-deficient populations are often most at risk of acquiring viral infections such as HIV or hepatitis C virus.
This review summarizes current basic science and clinical evidence examining zinc as a direct antiviral, as well as a stimulant of antiviral immunity. An abundance of evidence has accumulated over the past 50 y to demonstrate the antiviral activity of zinc against a variety of viruses, and via numerous mechanisms.
The therapeutic use of zinc for viral infections such as herpes simplex virus and the common cold has stemmed from these findings; however, there remains much to be learned regarding the antiviral mechanisms and clinical benefit of zinc supplementation as a preventative and therapeutic treatment for viral infections.
In vitro studies suggest that free zinc may possess potent antiviral effects, and are supported by trials of creams, lozenges, and supplements with high free zinc content. Moreover, zinc-binding proteins such as the metallothioneins may possess antiviral roles, although their specific function remains uncertain.
Nonetheless, zinc treatment applied at a therapeutic dose and in the right form has the potential to drastically improve the clearance of both chronic and acute viral infections, as well as their accompanying pathologies and symptoms.
Consequently, the role of zinc as an antiviral can be separated into 2 categories: 1) zinc supplementation implemented to improve the antiviral response and systemic immunity in patients with zinc deficiency, and 2) zinc treatment performed to specifically inhibit viral replication or infection-related symptoms (75, 78–82, 83, 85–91, 95–101, 103, 104).

The optimal range of plasma zinc is 13.8 – 22.9µmol/L ( 90-150µg/dl). Clinical signs of zinc deficiency may occur when plasma zinc concentrations drop below 9.9µmol/L (65 µg/dl)
