The immune system needs all the support it can get during a crisis.

In this uncertain time, strategies to shore up biological weaknesses and nutritional imbalances are at the very top of the list for boosting immunity.

Everything mentioned in this article has been shown to be effective for boosting immunity against viruses and even past coronaviruses in published studies.

We can strengthen the immune system from the ground up — via two avenues foundational to general health: nutrients and lifestyle.

Adults

Suggested Schedule

Multivitamin — Daily.
Vitamin D — Daily**
Vitamin A — Every other day**
Vitamin C — Daily.
Zinc — Daily**
Echinacea — Daily.
Heat — Daily, multiple sessions.
Sunlight — Daily, multiple sessions.

** for duration of illness, then stop.

If you’ve supplemented high doses — of any of these — in the past 6 months, consider skipping them during the illness.

Immune function may be improved by restoring deficient micronutrients to recommended levels, thereby increasing resistance to infection and supporting faster recovery when infected.

A Great Multivitamin

A strong multivitamin has A) whole-food based, high-quality ingredients at B) biologically-appropriate, balanced doses — not megadoses, which can create imbalances.

Naturelo’s formulation is well-balanced, absorbable, w/adequate zinc content — the only one of its kind among a vast ocean of subpar multivitamins.

Women’s includes iron.
Women’s (50+) is iron-free.

Take a quality multivitamin daily, with or without meals, before 2 pm.

Vitamins D & A

Vitamin D and Vitamin A are partner nutrients which are central to immune function.

Poorly represented in most diets (D is only available from sunlight and A is only available from liver), they are both critical for metabolism, sleep, and hormone production.

A deficiency in these can make you extra susceptible to illnesses.

D

Vitamin D is a hormone produced when the body receives UVB light.

Vitamin D is perhaps the most important immune nutrient.

Solaray, Soy-Free Vitamin D-3 + K-2, 120 VegCaps

Solaray 5000 IU (with K2)

This is a moderate-to-high dose of Vitamin D3 (the biologically-active form) with a small amount of cofactor Vitamin K2, needed to allow Vitamin D work in the body.

It’s an excellent idea to take absorbable magnesium to support Vitamin D. Magnesium is not readily found in modern food, so it’s a good idea to supplement it daily, anyway.

WHEN SICK, Take 5000IU Vitamin D daily — with a meal.

(Consider avoiding Vit D if supplemented heavily in the past — to avoid overdose).

NOTE — Sunlight is a superior form of Vitamin D, but is only available around midday, in the summer.

A

Vitamin A is the sister hormone to Vitamin D, enabling it to work optimally.

The two must be balanced with about a 1:1 ratio.

Carlson Labs, Vitamin A, 10,000 IU, 250 Soft Gels

Carlson Labs (10,000 IU)

This is the premier form of Vitamin A (preformed, fat-soluble). Does not require the liver to convert from carotenes.

When Sick, Take Vitamin A every Other day — with a meal, before 2pm.

(Consider avoiding Vit A if supplemented heavily in the past — to avoid overdose).

It is well-established that nutritional inadequacy greatly impairs the functioning of the immune system.

Vitamin C

Along with Vitamin D, Vitamin C is a most critical immune nutrient, because it supports the system’s energy as a whole.

Fat-soluble Vitamin C, an incredible product.

Take 500-1000mg daily, at any time, with or without a meal.

Higher doses should be used with caution, up to 1000-2000mg/day.

Various micronutrients are essential for immunocompetence, particularly vitamins A, C, D, E, B2, B6, and B12, folic acid, iron, selenium, and zinc.

Zinc & Copper

OPTIONAL: Extra Zinc & Copper?

If you haven’t done so in the last 6 months, supplement additional zinc for the duration of the illness.

Pure Encapsulations Zinc

(Amazon)

– Here’s a similar, excellent zinc product by Thorne Research on iHerb.

Certain minerals — such as zinc — have powerful antimicrobial properties. Pathogens are destroyed simply from contact with these minerals:

Zinc oxide nanoparticles are toxic to many fungi, viruses, and bacteria.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5940970/

When sick, take zinc:

— daily
— at any time
— with or without a meal

then stop (to prevent zinc overload).

Copper

Zinc and copper are partner nutrients.

Like zinc, copper is toxic to pathogens.

This excellent copper product: Chlorofresh (sodium copper chlorophyllin) is the best method to receive copper.

While there is some copper in the Solaray multivitamin, a little more from chlorophyll can be effective and help balance zinc.

Chlorophyll is the best source of bioavailable copper. View on Amazon.

Take one chlorophyll per day — anytime.

5

Echinacea

Several past studies have suggested that echinacea is effective at reducing the viability of all viruses.

Solaray Echinacea

(Amazon)

View on iHerb.com.

Take echinacea anytime, as directed.

If extremely ill, discontinue.

Other antiviral herbs may be viable alternatives to boost immunity during illness. Here’s a list of options:

6

Heat

Heat is incredibly therapeutic for nearly every health condition — especially for supporting the immune system.

Why? In part, because pathogens are severely weakened in high heat. Look no further than what your own body does when sick: It raises the temperature in your tissues, a fever.

Venture Soft Far Infrared Heating Pad

UTK Ultra-Soft Far Infrared Heating Pad

Exposure to warmth is critical when fighting off illness and preventing it. The heat will also help you feel better in the process.

Apply heating pad for 20 minutes on chest, then 20 minutes on the back. Optional: Sit on pad for several hours.

Did you know? Heat is infrared light.

7

Sunlight

If you’re sick, get outside.

UV light is naturally germicidal — especially against viruses. UV frequencies can penetrate into the skin, and can even inactivate viruses that have worked their way into skin tissues.

Blue light from sunshine, as well, is “highly antimicrobial.”

Infrared, the immune-boosting and germicidal to pathogens, is also metabolism boosting and makes up 50% of sunlight.

Sunlight is a premier tool to:

sync the circadian rhythm and ensure excellent sleep, night after night
boost digestion
speed up the metabolism

…all important for recovery from illness.

UV radiation kills viruses by chemically modifying their genetic material, DNA and RNA.
https://www.ncbi.nlm.nih.gov/pubmed/17880524

Morning light is the healthiest light you can get — even without any UV.

Don’t wait until you’re sick to spend time outdoors. Ward off illness — before it arrives — with regular sunshine.

Get outdoors every day — for as long as possible.

8

The immune system activates at night — functioning best when we sleep deeply.

Research is finding that when you sleep is more important than how many hours you sleep. Thus, the circadian rhythm is more important than the total hours of shuteye.

Fix the circadian rhythm to fix sleep. Explore the Sleep section for more.

Children

When it comes to children, it’s important to simplify.

Kids are smaller bodies that require smaller doses of nutrients. Children’s health needs are different than an adult’s — they are often more sensitive, and thereby susceptible to harm caused by excessive supplementation.
