The one certainty that we have as we enter a seventh week of lockdown is that there is no known cure – yet – for Covid-19.

It will come, but too late for the many thousands who have already succumbed to it and the thousands more who will do so in the weeks and months to come.

Could it be, though, that we have an eye on the horizon when the solution to at least  stemming the apparently relentless march of this disease is naturally available in limitless supply and already known to us?

If, instead of focusing exclusively on the pursuit of a cure, we turned our attention to improving our natural immunity and capacity for fighting viral infections, we may not only turn the tide against the main complication of Covid-19 infection: acute respiratory distress syndrome (ARDS).

There are three natural, yet scientifically proven ways that the human immune system can be strengthened and supported to fight viral infections like the coronavirus.

These are vitamin D, vitamin C (which I have also discussed in a previous blog) and iodine.

For anyone who might feel a certain scepticism that such an obvious answer could be staring us in the face, there are plenty of studies and trials that bear out the power of each of vitamins C and D and iodine as powerful allies in human immunity.

Our immune system is a complex marvel that’s designed to protect us against threats in our internal and external environments, but often our lifestyle inhibits and weakens this natural process, leaving us with a debilitated immunity that leaves us increasingly vulnerable – particularly as we age – to serious infection.
