Nutrients that boost our immune system

By David Coory

No more colds in recent years

In more recent years, because of better nutrition and other health principles to boost my immune system (like fresh air), I’ve even been able to eliminate miserable, regular colds in my life.

I’m tempting fate by saying this, but I love to share what’s worked for me, and would like viruses to be a thing of the past for you too.

Why I have no fear of covid

I don’t mean to imply that I won’t catch covid, but I do feel confident that my immune system is strong enough to deal with it at the very early stage, even perhaps to the extent that I wouldn’t know I had it.

This is generally the experience of children who contract the virus. The highly respected Dr Peter McCullough claims that the majority of US children have already contracted the virus, but for most of them it has been no more than a mild sniffle. This is because their body’s main immunity fighter, glutathione, is generally at a high level because of their youth.

Glutathione is our main virus fighter

Many have never heard of glutathione. It’s a protein made by our liver and has a very powerful immunising effect, protecting us against all kinds of infectious diseases and viruses, and also toxins. It’s absolutely vital to our immune system and our health.

However, our glutathione level normally begins to decline from age 30. Very low levels are found in nearly all persons who suffer from old-age degenerative diseases.

Glutathione has not proved to work when taken as a supplement but curcumin (found in turmeric) and the vitamins and minerals listed below boost levels, and also, vigorous exercise.

Vitamins and minerals that boost glutathione

The nutrients that boost our glutathione are – vitamin A, vitamin B1 (thiamine), vitamin B6, vitamin D, vitamin B12, vitamin C, CoQ10 and Omega 3.

Also, the important minerals – zinc, iodine, magnesium and selenium.

Should we take more zinc or vitamin D?

If our sense of smell and taste is good, our zinc levels should be OK. A poor sense of smell is a reliable sign of zinc deficiency. Men have a higher need for zinc - 14 mg/day compared to women - 8 mg/day. More than 20 mg a day of zinc on a regular basis can actually suppress our immune system.

Vitamin D is extremely important. A good vitamin supplement and regular full sun exposure without sunblock (or sunburn) is invaluable.

Quercetin – another natural virus protector

Another nutrient that protects us against viruses is quercetin. It’s plentiful in honey, raw onions, garlic, ginger, citrus, green tea and the skins of fruit, especially apples, plums and red berries. Cooking destroys quercetin.

Quercetin can also be found in bioflavonoids and in some vitamin C formulas.

Herbs that support your immune system

There are also herbs that support our immune system. These are echinacea, garlic, olive leaf and astragalus.
