In a new landmark study, researchers reveal the optimal vitamin D levels for cancer prevention and survival.
An optimal blood level of vitamin D is essential for a strong immune system.
We have an epidemic of vitamin D deficiency. It’s estimated that nearly half of Americans have “insufficient” vitamin D levels (under 29 ng/ml) and 14 percent are deficient (under 19.6 ng/ml).
Vitamin D blood levels of 50 ng/ml or higher have been found to protect against respiratory infections like influenza or corona type viruses. D3
Vitamin D increases the production of cathelicidins, anti-microbial peptides which destroy viruses, bacteria, parasites, and pathogens.
Adequate sunshine and/or supplementing with Vitamin D3 appears to be one of the cheapest and best ways to support your innate immune system against flu and corona-type viruses.
A review of 25 trials published in the British Medical Journal in 2017 concluded that vitamin D supplementation clearly protects against acute respiratory tract infections, especially for those deficient in D3.
Researchers found that daily or weekly dosing was more effective than a large one-time dose.
The review indicated that for every four people given vitamin D one case of respiratory infection was prevented. Vaccination typically must be given to 44 people to prevent one case of respiratory infection. Based on this, it appears that Vitamin D supplementation might be 10 times more effective at preventing the flu than a flu shot.
A randomized trial which gave vitamin D3 to Japanese schoolchildren found that those who were given 1200 IU of vitamin D per day from December through March had nearly half as many cases (10% vs 18%) of influenza A than those in the placebo group. The children taking D3 also had fewer asthma attacks (2 vs 12).
Supplementing with 5,000–10,000 IU per day of D3 may be necessary to reach protective blood levels, depending on multiple factors, which I discuss below.
