No evidence that vitamin D prevents coronavirus, say experts

Nice says topic is under review, but still advises taking supplements for bone health

No evidence exists to support taking vitamin D supplements to prevent Covid-19, UK public health experts have found.

A rapid review of evidence for claims that the so-called sunshine vitamin could reduce the risk of coronavirus was launched amid concerns about the disproportionate number of black, Asian and minority ethnic people contracting and dying from the disease. Higher levels of melanin in the skin lead to less absorption of vitamin D from sunlight.

However, on Monday, the National Institute for Health and Care Excellence (Nice) said that, having examined five studies, it had not found evidence to support any benefit from vitamin D with respect to Covid-19.

A Man Got Kidney Failure From Taking Too Much of Vitamin D

Posted 22 May 2019


Too much of a good thing can be downright disastrous. After taking 8 to 12 drops of concentrated Vitamin D every day for two-and-a-half years, a 54-year-old man in Canada has inadvertently and permanently damaged his kidneys.

He used it as prescribed by a naturopath at a dose well above the recommended daily allowance, and now it has taken a year of treatment for the patient’s blood to return to normal, while some organs never will – he is ultimately burdened with stage 3B chronic kidney disease.

The physicians who published his case in a medical journal are worried that others might fall into the same innocent trap.

“Our experience informs us that patients and clinicians should be better informed about the risks regarding the unfettered use of vitamin D,” the authors suggest.

“Given new findings from the US Preventive Services Task Force, current Canadian Read the rest

Vitamin D: Is Sunscreen the New Margarine?

Posted 17 January 2019

By Rowan Jacobsen – Published Jan 10, 2019 in

Current guidelines for sun exposure are unhealthy and unscientific, controversial new research suggests-and quite possibly even racist. How did we get it so wrong?

These are dark days for supplements. Although they are a $30-plus billion market in the United States alone, vitamin A, vitamin C, vitamin E, selenium, beta-carotene, glucosamine, chondroitin, and fish oil have now flopped in study after study.

If there was one supplement that seemed sure to survive the rigorous tests, it was vitamin D. People with low levels of vitamin D in their blood have significantly higher rates of virtually every disease and disorder you can think of: cancer, diabetes, obesity, osteoporosis, heart attack, stroke, depression, cognitive impairment, autoimmune conditions, and more. The vitamin is required for calcium absorption and is thus essential for bone health, but as evidence mounted that Read the rest

Vitamin D: a pseudo-vitamin for a pseudo-disease

Posted 06 September 2018

This is an important and interesting perspective of Vitamin D supplementation. It is written by Prof Tim Spector, Professor of Genetic Epidemiology, King’s College London, and published in The Conversation.

He concludes:

About half the population take vitamins daily, despite zero benefits, with increasing evidence of harm. The worldwide trend of adding unregulated vitamins to processed food has now to be seriously questioned.

While vitamin D treatment still has a rare medical role in severe deficiency, or those bed bound, the rest of us should avoid being “treated” with this steroid for this pseudo-disease and focus on having a healthy lifestyle, sunshine and importantly save your money and energy on eating a rich diversity of real food.

Cautionary tale of 4-year-old autistic boy rushed to ER after treatment with supplements

Posted 13 October 2016

[quote]We probably underestimate the use of CAM, but studies suggest that it is particularly prevalent in cases such as autism where there are limited conventional medical treatment options and advice regarding complementary therapies is not regulated. Boyd et al. BMJ Case Reports[/quote]

Washington Post

If you search for the words “autism” and “treatment” online, you’ll find all kinds of suggestions outside of accepted medical practice for how to try to minimize or even cure the symptoms. Some of those ideas can be dangerous.

Doctors recently described what happened to a 4-year-old boy who showed up in the emergency room after having been sick for three weeks. He was throwing up, had lost his appetite, was constipated and extremely thirsty, and had lost more than 6.5 pounds in two weeks.

The mother confessed a few days after his admission to the … Read the rest

Vitamin D supplements are not effective, and could be dangerous, studies find

Posted 26 January 2016

This article, written by Prof. Tim Spector, Professor of Genetic Epidemiology, King’s College London, argues that evidence to support the claims for Vitamin D is lacking, and that taking Vitamin D may even be dangerous. Solal made outrageous claims for its Vitamin D supplements, including that it was more effective than vaccines!

[quote]However, a new paper on the risks that vitamin D may pose finally has convinced me that I was wrong. My view on vitamin supplements and the multi-billion dollar industry behind them altered radically after I began researching my book, The Diet Myth, in 2013. The industry and its PR is supported by celebrities who reportedly have high-dose vitamins drip fed into their veins, and around 50% of Americans and Britons take them regularly. But surprisingly, there is a lack of evidence to support the health benefit claims of virtually all vitamin supplements… Read the rest

Vitamin D not effective for colds and respiratory tract infections

Posted 27 January 2014

Readers will be aware that some while ago, Solal made claims in adverts that Vitamin D is effective for colds/influenza. We pointed out that the claims were false, and the data from the study they used (Japanese schoolgirls), misconstrued.

Two studies published, one at the end of 2013, where Vitamin D/D3 was tested to see if it would work in preventing influenza/colds, found that they did not. Will Solal change their claims? Unlikely, selling Vitamin D and making money is more important.

ASA: Solal’s Vit D still not as effective as Vaccine

Posted 15 February 2012

Solal previously ran ads claiming that “Vitamin D is as effective as a vaccine”. The ASA ruled in favour of a complaint laid with the ASA by a consumer, Kevin Charleston, against this claim, arguing that this claim is false and unproven. Solal submitted new substantiation to support this claim.

Here is the ruling on the new substantiation. It is very interesting how the ASA have phrased or highlighted a number of sentences.

“It would appear that the respondent does not take the time to consider such allegations and merely hurls them at the ASA in an attempt to frustrate the process.” (ASA)

“However, cherry picking individual analyses as the respondent has done and applying them without due consideration is abysmal science.” (Kevin Charleston)

“While not material for the purpose of this ruling, the Directorate would like to express its disappointment at the respondent’s allegation that Read the rest

Solal advert “Vitamin D is as effective as a vaccine”

Posted 17 May 2010

Solal has placed this advert in a number of newspapers. I have received calls from dietitians, doctors and pharmacists complaining about the claims of this advert.So, what is the truth?

Here is a good scientific deconstruction by one of South Africa’s best journalists, Elsabe Brits of Die Burger newspaper.
