April 23rd: The FTC criminalizes nutritional advice about vitamin D and zinc in latest ploy to protect market monopoly for unproven, dangerous vaccines

4/23/21

https://pandemic.news/2021-04-23-april- ... -zinc.html


As we covered in a Natural News article, the FTC has gone full tyranny against a St. Louis chiropractor for selling vitamin D and zinc supplements that he says may help people avoid being harmed by covid. According to the FTC and the lying corporate media that shills for the vaccine industry, this chiropractor made false claims by saying vitamin D and zinc might work against covid.

Yet the very same corporate media liars routinely claim unproven vaccines work against covid, even when no vaccine has been approved by the FDA as being safe and effective for treating covid-19 in any way whatsoever. The FDA’s emergency authorization for covid vaccines isn’t a declaration that the vaccines work (or that they are safe), which means every media outlet claiming vaccines prevent infections or reduce transmission is engaged in blatant fraud and pseudoscience quackery.

Yet the FTC takes no action against the media, even when media networks are receiving advertising money directly from vaccine makers.

Once again, it’s incredibly obvious that government regulators are being weaponized against humanity, targeting truth-tellers and individuals trying to help save lives, all while protecting the criminal vaccine racket that’s being rolled out to deliberately reduce the global population and exterminate humanity as part of a whole new “vaccine holocaust.”

In other words, if you talk about a supplement that works to save lives, you will be targeted, fined and criminally charged. But if you use false claims to promote dangerous vaccines that are killing people and causing infertility, you will be celebrated and probably even financially rewarded by the CDC to keep pushing more propaganda.

Vitamin D is widely supported as a supplement to support immune function during any infectious disease pandemic. As explained on Covid.US.org, Over 100 Scientists, Doctors, & Leading Authorities Call For Increased Vitamin D Use To Combat COVID-19.

All the efforts of the fake Biden regime are now focused on destroying humanity, gutting the U.S. economy, spreading infectious disease, flooding the United States with illegals, censoring free speech and criminalizing political opponents who are often kept jailed as political prisoners. We are living under fascism tyranny, and the criminal medical cartels are pocketing tens of billions of dollars in profits while they exterminate humanity and enslave the survivors.

If We the People do not (peacefully) rise up and resist this insanity, we will all die as slaves under medical tyranny.

Over 100 Scientists, Doctors, & Leading Authorities Call For Increased Vitamin D Use To Combat COVID-19

https://covid.us.org/2020/12/10/over-10 ... -covid-19/


Here’s the Open Letter on Vitamin D and Covid-19. Over 100 physicians, researchers, and other experts signed a statement asking that ALL Adults take:

* 10,000 IU of vitamin D3 every day for 2 to 3 weeks
* And then take 4,000 IU of vitamin D3 every day continuously (or at least until the pandemic is over)

However, the experts each stated how much vitamin D they themselves are taking daily, and some were taking as much as 10,000 IU per day. The only signatory who is not taking vitamin D is a researcher in Australia where they are now heading into the Summer season. He probably knows his vitamin D level, and gets plenty of sunshine on skin to make vitamin D.

I’ve read many studies on vitamin D, and as a result, I now take 20,000 IU daily. Given the 40 plus studies that show the benefits of Vitamin D against Covid-19, I prefer to take a higher than usual dose to obtain as much protection as possible. See these Studies on Vitamin D and Covid-19

Vitamins to take with Vitamin D, while you are well:
Vitamin C, 500 mg 2x/day
Vitamin K1 and K2
Selenium 200 micrograms/day
Zinc 30 mg/day
and a B-complex multivitamin

There is a study showing the benefits of high-dose vitamin D for persons who have Covid-19:

Rastogi, Ashu, et al. “Short term, high-dose vitamin D supplementation for COVID-19 disease: a randomised, placebo-controlled, study (SHADE study).” Postgraduate medical journal (2020). Study Link
— Covid-19 patients were given 60,000 IU vitamin D daily for 7 days; these patients were 3.0 times more likely to become negative for Covid-19 than patients not given vitamin D.

Some of the patients given 60,000 IU for 7 days still did not have optimum levels by the 7th day, so they were continued on the 60,000 IU per day dosing.

If I had Covid-19, I would immediately start taking 50,000 IU of vitamin D3 each day for 7 days, and then switch to 10,000 IU per day continuously.

I have a set of supplements that I recommend to friends and family if they have Covid-19:

Vitamin D (see above)
Vitamin C 1000 mg/day
Vitamin K1 and K2 (Life Extension “Super K”)
Selenium 200 micrograms/day
Zinc 30 to 50 mg/day
Quercetin 250 mg 2x/day
B-complex vitamins
Aspirin 325 mg/day
Melatonin 3 mg timed release (increase gradually to 9 mg) once a day about an hour before bed (causes sleepiness)
and
** Ivermectin, a prescription medication, if you can convince your doctor to prescribe it.

A Year In, Here's What We Know About Vitamin D For Preventing COVID

4/14/21


https://www.npr.org/sections/health-sho ... ting-covid


When the pandemic hit, many Americans turned to vitamins and supplements in hopes of boosting their immune systems.

Scientists also raced to study them. Vitamin D, perhaps more than any other, captured the attention of researchers.

Even the nation's top infectious disease doctor, Anthony Fauci, embraced the idea of using the vitamin to help keep COVID-19 at bay, saying in September that he takes a supplement to avoid being deficient and "would not mind recommending" it to others.

So should you take vitamin D to prevent or even treat COVID-19?

More than a year into the pandemic, many of the studies that can offer high-quality evidence are still in the works, but there's now enough out there to offer clues — as well as fodder for spirited debate — about the question.

But first — why vitamin D?


It's unrealistic to think any one supplement can be a cure-all, but there are some compelling reasons to study vitamin D in the context of COVID-19.

Vitamin D plays a vital role in bone health and, along with calcium, helps prevent people from developing osteoporosis. And there's growing evidence it helps keep the immune system running properly.

In recent years, researchers have increasingly studied the effect of vitamin D supplementation on respiratory infections, with some clinical trials finding no meaningful effect and others suggesting it can be protective.

A 2017 review study that analyzed 25 randomized, controlled trials concluded vitamin D helped prevent acute respiratory tract infections.

Vitamin D may help boost the innate immune system in a number of ways, said Dr. Adit Ginde, a professor of emergency medicine at the University of Colorado School of Medicine and one of the study's authors. One mechanism, he said, is by increasing antimicrobial peptides, which function as natural antibiotic and antiviral guards against pathogens.

Though some researchers are not yet convinced of the evidence for vitamin D and respiratory illness, others, such as Ginde, are. "Based on those mechanisms, prevention [of COVID-19] would be the first scenario that you would expect to work," Ginde said. "It's also very clear deficiency causes dysfunction in the immune system."

The link with COVID-19

It's estimated as much as 40% of the U.S. population doesn't get enough vitamin D and as many as 1 billion people worldwide have deficient levels.

Early in the pandemic, researchers noticed the overlap between populations that were at high risk of severe illness from COVID-19 and those likely to have vitamin D deficiency, in particular people who are overweight, elderly and those with darker skin.

It sparked a rush of commentary and academic articles on whether boosting vitamin D levels could help shield certain vulnerable people from coronavirus infection.

There are now quite a few observational studies and large reviews of the available evidence that show low vitamin D levels are associated with higher risks of contracting COVID-19 or with becoming seriously ill.

"What is clear from a number of studies is that there's a strong relationship in terms of your levels prior to infection," said Dr. Shad Marvasti, a professor of family and preventive medicine at the University of Arizona College of Medicine in Phoenix.

Low levels of vitamin D are associated with an increase in cytokines — "cell to cell chemical messengers that are responsible for inflammation" — and lower levels of protective immune cells, Marvasti said.

A study of 489 patients published in JAMA Network Open in September found "the relative risk of testing positive for COVID-19 was 1.77 times greater" for patients who were likely vitamin D deficient compared with those with sufficient levels.

"That was really very striking," said Dr. David Meltzer at the University of Chicago, who was the lead author of that study. "I started taking it and telling all my family and friends."

In another recent study, Meltzer has also found that Black individuals with high levels of vitamin D were less likely to test positive than those who had levels traditionally considered sufficient.

Another small study of patients hospitalized for COVID-19 in Spain found over 80% had vitamin D deficiency, compared with 47% of the general population; however, it did not find any relationship between vitamin D levels and the severity of disease.

"If I had money on it, I would bet that it's more likely that vitamin D is helpful than not in COVID, but I don't know for sure," Meltzer said.

No "firm conclusions"


While these studies raised hopes among some researchers, others are skeptical, noting that most of these are observational studies, not the gold-standard randomized, controlled trials.

Much of the available evidence only shows association — not causation — and even those results are mixed, said Walter Willett, a professor of nutrition and epidemiology at the Harvard T.H. Chan School of Public Health.

"It would be one thing if we had very consistent evidence, but it's showing either some benefit or no benefit at all," Willett said. "At this point in time, we can't really draw any firm conclusions."

Indeed, some observational studies have found no significant associations when it comes to key questions around COVID-19 and vitamin D levels.

Researchers in Greece recently concluded that vitamin D deficiency was "not significantly associated with infections, recoveries or mortality rate of COVID-19 among European countries." And, in December, an agency for the U.K.'s National Health Service reviewed the evidence and advised the public not to take vitamin D solely to prevent or treat COVID-19.

"We haven't ruled out vitamin D completely, but I'm skeptical, having worked in this field for 15 years," said Dr. Erin Michos at Johns Hopkins School of Medicine, who has studied the effect of vitamin D on heart attacks, strokes and other cardiovascular diseases.

Researchers have spent years tracing the association between low vitamin D and other diseases — obesity, diabetes, cardiovascular disease, depression, multiple sclerosis and cancer — but have either ended up with inconsistent results, or found no clear benefit from supplementation.

People with low vitamin D levels tend to be less healthy overall: They spend less time outdoors and have less exposure to sunlight, and people who are overweight often have lower levels because fat cells sequester vitamin D.

"So vitamin D deficiency is associated with things like older age, obesity and being a minority ethnicity," Michos said. "Yet those are the same risk factors that are associated with severe COVID."

This overlap makes studying the impact of vitamin D on COVID-19 tricky because it's difficult to tease apart whether low levels are actually causing people to be more susceptible.

"It may just be a marker of poor health and not actually something that can be intervened on to prevent COVID," Michos said.

What about treating COVID-19?

Research on using vitamin D as a therapeutic intervention once people are infected with the coronavirus has produced slightly more high-quality data, although the studies offer an inconsistent picture.

The most substantive evidence comes from a randomized, placebo-controlled trial in Brazil. There, doctors gave hospitalized COVID-19 patients one large dose of vitamin D and concluded it "did not significantly" reduce patients' length of stay in the hospital compared with the placebo group.

There are some caveats: Patients did not receive vitamin D until later in the illness, and it was a single large dose, rather than more incremental, frequent dosing, which seems to "work better for protecting immune function," the University of Chicago's Meltzer said.

While the 240-person study could have easily missed "clinically important benefits," the results are not encouraging, said Ginde of the University of Colorado, who co-wrote an editorial about vitamin D and COVID-19 for JAMA.

"If it was a panacea, you would see it," he said.

So what should you do?

So far, there is simply not enough evidence to recommend confidently taking a certain dose of vitamin D to fight off COVID-19, but experts stress it's reasonable to pay attention to whether people are getting enough, especially during winter months when levels tend to sink.

"There are many good reasons to avoid low vitamin D levels. ... A supplement is really the most reliable way to get it," Harvard's Willett said.

But, as with many vitamins, Willett stresses that "more is not better."

Because vitamin D is fat-soluble (unlike vitamin C, which is water-soluble), there is a risk that overshooting with supplementation can lead to toxicity, with some research showing that taking more than 50,000 IU, or international units, regularly can be harmful.

There are varying guidelines for how much vitamin D adults should get on a daily basis, ranging from about 400 to 1,000 international units, according to the Endocrine Society.

Marvasti said most people could "probably get away with about 1,000 IU per day," although it's best to first check your baseline levels and speak to a doctor.

"Given the role that vitamin D is known to play in immunity and other medical conditions, to me, what's the harm?"

Some clinicians are more wary.

"I'm not advising patients to take it to prevent COVID-19," said Michos at Johns Hopkins.

Putting aside the debate over vitamin D, Michos points out there are plenty of time-tested ways to boost the immune system — eating vitamin-rich food such as fruits and vegetables, exercising regularly, drinking alcohol in moderation and importantly, getting enough sleep.

"I don't think that patients need to necessarily waste their money on supplements," she said.

But Meltzer, who is more hopeful about the potential benefits of taking vitamin D, points out there are still big gaps in the understanding of what is a "normal" level, "because those have been defined largely on bone health."

"We don't know really what the ideal levels are for immune function," he said. "Depending on your skin tone and racial background or genetic background, there are very, very different needs, so this is an area that desperately needs more data."

Study finds no genetic evidence to prove vitamin D protects against coronavirus

6/5/21


https://www.news-medical.net/news/20210 ... virus.aspx


While previous research early in the pandemic suggested that the vitamin D cuts the risk of contracting COVID-19, a new study from McGill University finds there is no genetic evidence that the vitamin works as a protective measure against the coronavirus.

"Vitamin D supplementation as a public health measure to improve outcomes is not supported by this study. Most importantly, our results suggest that investment in other therapeutic or preventative avenues should be prioritized for COVID-19 randomized clinical trials," say the authors.

To assess the relationship between vitamin D levels and COVID-19 susceptibility and severity, the researchers conducted a Mendelian randomization study using genetic variants strongly associated with increased vitamin D levels. They looked at genetic variants of 14,134 individuals with COVID-19 and over 1.2 million individuals without the disease from 11 countries.

In the study published in PLOS Medicine, the researchers found that among people who did develop the disease, there was no difference between vitamin D levels and a likelihood of being hospitalized or falling severely ill.
Studying the effects of vitamin D

Early in the pandemic, many researchers were studying the effects of vitamin D, which plays a critical role in a healthy immune system. But there is still not enough evidence that taking supplements can prevent or treat COVID-19 in the general population.

" Most vitamin D studies are very difficult to interpret since they cannot adjust for the known risk factors for severe COVID-19 such as older age or having chronic diseases, which are also predictors of low vitamin D."

- Guillaume Butler-Laporte, co-author, physician and fellow under the supervision of Professor Brent Richards at McGill University

"Therefore, the best way to answer the question of the effect of vitamin D would be through randomized trials, but these are complex and resource intensive, and take a long time during a pandemic," he says.

By using a Mendelian randomization, the researchers say they were able to decrease potential bias from these known risk factors and provide a clearer picture of the relationship between vitamin D and COVID-19.

However, researchers noted that their study had some important limitations. It did not account for truly vitamin D deficient patients, consequently it remains possible that they may benefit from supplementation for COVID-19 related protection and outcomes. Additionally, the study only analyzed genetic variants from individuals of European ancestry. Future studies are needed to explore the relationship with vitamin D and COVID-19 outcomes in other populations, say the researchers.

"In the past Mendelian randomization has consistently predicted results of large, expensive, and timely vitamin D trials. Here, this method does not show clear evidence that vitamin D supplementation would have a large effect on COVID-19 outcomes," says Butler-Laporte, who is a microbiologist and an expert in infectious diseases.
