If there is a second wave of coronavirus, one of the best defenses will be Vitamin D supplementation. From Joseph Mercola at lewrockwell.com:
As health officials continue to expect a second wave of COVID-19 this fall, spreading information about how to prevent it is becoming crucial. One of the most important strategies in this regard is to optimize your vitamin D level.
Vitamin D not only helps regulate immune function and prevent respiratory illnesses in general, but mounting data analyses show clear parallels between vitamin D levels and the risk of infection, severity and mortality from COVID-19 as well.
While U.S. authorities are still trying to debunk (and even instill fear) of vitamin D supplementation, British and Scottish authorities appear to be embracing a more sensible approach.
The British Frontline Immune Support Team, founded “to make available some of the best quality immune supportive products … to help keep those on the NHS (UK National Health Service) frontline resilient and strong,” is already providing health care workers with free nutritional supplements known to bolster and regulate immune function.
