COVID-19: How to Prepare for the Emerging Threat

As you well know, COVID-19 is highly contagious and in approximately 3-4% of cases, deadly. As expected, certain populations are at greater risk, including the very young, the elderly, and those individuals who are currently immunocompromised.

While COVID-19 has not previously been identified in humans, its viral cousins have been around throughout human history. Given that we have persevered through many iterations of this threat, it would be prudent to forgo panic and focus on time-tested strategies that have served us well in the past.

While we may not have a natural immunity to COVID-19 specifically, it is possible to improve our immune potential if exposed to the virus.

The essential nutrients:

Vitamin D3

  • 400 to 3000 IU for children
  • 2000 to 5000 IU for adults

Values should not exceed more than 35 IU per pound of body weight for more than a few weeks.

Vitamin C

  • 250 to 500 mg for children 2 times per day
  • 500 mg for adults up to 3 times per day


  • 10 to 15 mg per day for children
  • 30 to 75 mg per day for adults

Values should not exceed the Recommended Daily Intake [RDI] for more than 7 days.



  • 300 to 600 mg daily for children
  • 600 to 1200 mg daily for adults


  • ½ teaspoon 1 to 2 times daily for children
  • 1 to 3 teaspoons daily for adults
  • 150 to 300 mg extract daily for adults

In addition to these supplements, care should be taken to maintain normal body temperature, stay well hydrated, and get at least 7-8 hours of sleep every night.

And don’t forget to wash your hands!
