Vitamins are nutrients that the body cannot create, so we must consume them in our diet. The exception however is vitamin D which the body can produce on its own. Despite its name, vitamin D is not a vitamin, but a prohormone, or precursor of a hormone.
Vitamin D is essential for several reasons, including maintaining healthy bones and teeth. It may also protect against a range of diseases and conditions, such as type 1 diabetes. Vitamin D by nature is an anti-inflammatory. Deficiency causes immune system weakness and chronic inflammation.
A recent study "Vitamin D supplementation to prevent acute respiratory tract infections: systematic review and meta-analysis of individual participant data", claims to find evidence that vitamin D prevents respiratory infections, especially in older adults whose vitamin D levels are low. Although its specific role in corona virus infections is still unknown, researchers vouch for its effectiveness in boosting the immune system. The study suggests that deficiency in vitamin D may be a factor in one's deteriorating condition, should they be contracted with COVID-19.
For prevention, supplement with 5,000 - 10,000 IU of vitamin D daily which is safe for most adults. Vitamin D is effective for prevention of the flu, colds, cancer and approximately 200 different diseases.
Mushrooms are the only food that contain vitamin D, naturally. All other natural food sources of vitamin D are of animal, poultry or seafood origin. Also, some foods, such as milk, orange juice and cereals may be fortified with vitamin D, up to 100 IU.
Cultivated mushrooms contain a plant sterol called ergosterol, which is the precursor of Vitamin D². In fresh mushrooms, ergosterol is stimulated to convert to vitamin D² by ultraviolet light, either from sunlight or artificial lights.
Humans manufacture our own antibiotic through vitamin D stimulation. Vitamin D promotes production of cathelicidin, a protein with antibiotic properties. Catheelicdin kills viruses, bacteria, fungi, and parasites. The more vitamin D in our system the more the body makes this antibiotic.
According to the study Photobiology of vitamin D in mushrooms and its bioavailability in humans, “Mushrooms exposed to sunlight or UV radiation are a good source of vitamin D2.”
Additionally, the study states, “The bio availability of vitamin D2 in mushrooms compared with the bio availability of vitamin D2 or vitamin D3 in a supplement revealed that ingestion of 2000 IUs of vitamin D2 in mushrooms is as effective as ingesting 2000 IUs of vitamin D2 or vitamin D3 in a supplement in raising and maintaining blood levels of 25-hydroxy vitamin D which is a marker for a person’s vitamin D status.”
The study concludes with something that we love to share with those interested in the wonderful world of fungi. “Mushrooms are a rich source of vitamin D2 that when consumed can increase and maintain blood levels of 25-hydroxyvitamin D in a healthy range.”
Dr. John Cannell of the Vitamin D Council recommends taking 50,000 IU daily of vitamin D at the fist sign of the flu for 5 days. Then dropping the level down to 5-10,000 IU daily. There is overwhelming evidence that vitamin D prevents infection. World authorities on vitamin D verify that up to 30,000 IU daily for a healthy adult is quite safe and that periodic higher does 50,000 IU daily for 5 days are also of no concern. Vitamin D works even better if taken with vitamin K2. Both are anti-inflammatory and can prevent as well as treat infections successfully.
In addition to Vitamin A, fiber, and potassium, chaga is rich in a host of vitamins, including amino acids, B-complex vitamins, and ergosterol - vitamin D2. One can also benefit from a host of minerals like calcium, cesium, copper, iron, magnesium, manganese, rubidium, selenium and zinc.
