Mounting research suggests vitamin D deficiency may actually be a major cause of influenza. People with the lowest vitamin D levels report having significantly more colds or cases of the flu
Scientific review confirms vitamin D optimization boosts immunity and cuts rates of cold and flu. Among people with vitamin D blood levels below 10 ng/mL, taking a supplement cuts the risk of respiratory infection by 50%
To prevent influenza in one person, 40 people must receive the flu vaccine whereas one case of the flu can be prevented for every 33 people taking vitamin D. If you’re severely vitamin D deficient, vitamin D supplementation is 10 times more effective than the flu vaccine.
Besides vitamin D, there are a number of other foods and supplements that can be beneficial for colds and influenza, including the following:
Garlic
Zinc
Vitamin C
Oregano Oil
Medicinal Mushrooms
Propolis
Olive Leaf Extract"
