Coronavirus – nutrients for a resilient immune system:
A strong healthy immune system is one of our best weapons against the coronavirus – in combination with measures such as handwashing, social distancing, enough sleep and stress reduction.
Build your resilience against viral infections by concentrating on the nutrients listed below:
Vitamin C: our best known anti-oxidant and one that quickly gets depleted when we are stressed or ill. The basis for using high doses of vitamin C to prevent and combat virus-caused illness may be traced back to vitamin C’s early success against polio, first reported in the late 1940s. I recommend supplementing with vitamin C in addition to food sources, e.g. kiwi fruit, citrus fruit, tomatoes, red peppers, strawberries, broccoli and cauliflower.
Vitamin D: our sunshine vitamin (strictly speaking a hormone) that is a key element in supporting the immune system. Studies show that Vitamin D has anti-viral properties. It is difficult to get adequate levels for immune support from foods containing vitamin D (oily fish, liver, egg yolks) – supplementation is therefore really important.
Vitamin A: needed for good vision, growth and crucially, the health of our mucous membranes (eyes, nose, lungs, digestive and urinary tract. Vitamin A boosts the immune system and can help control the rapid reproduction of viruses. As the coronavirus can enter the body via our eyes, nose and lungs, this is a crucial nutrient for virus protection. Food sources include meat, eggs and dairy products.
Zinc: works with vitamin A to strengthen the immune system. It is particularly efficient in protecting the mucus layer in our airways. Again, coronavirus can lead to pneumonia, so keeping optimal zinc levels is paramount.
Selenium: A lack of selenium increases vulnerability to infection from viruses. Food sources include Brazil nuts, fish and meat.
Olive leaf extract: It contains oleuropein which has potent anti-viral activity against respiratory viruses.
Saccharomyces boulardi: this probiotic yeast probiotic yeast supports secretory immunoglobulin A (sIgA), the major immunoglobulin of the innate immune system which protects against infections.
Suggested doses to strengthen your immune system:
Vitamin C: 3,000 milligrams (or more) daily, in divided doses. Can increase up to 1g every 30 minutes in an acute infection.
Vitamin D3: 2000 – 4000 IU (International Units daily). (Start with 5,000 IU/day for two weeks, then reduce). Consider having a test to determine individual needs.
Vitamin A: 6,000 International Units daily.
Zinc: 20 mg daily.
Selenium: 100 mcg (micrograms) daily.
Olive Leaf extract (18% minimum oleuropein): 500 mg twice daily.
Saccharomyces boulardii: 3 Billion 3x daily.
