Vitamin D Is More Effective Than Flu Vaccine, Study Says

Story at-a-glance…
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 cut risk of respiratory infection by 50 percent.
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.
