Vitamin D For Influenza

Study: Vitamin K2, D helps help protect those sick with COVID-19

I thank Dr Korownyk and colleagues for their interesting review on the neuraminidase inhibitors.1 Having spent some time looking at the reviews on these drugs myself, I agree that they are not very useful and the risk of causing harm is greater than the purported benefit. I no longer use them in my patients. Unfortunately, they are administered facility-wide in nursing homes as a public health measure when there is a reported outbreak of influenzalike illness or influenza. Working in long-term care settings, I have seen some of these patients and staff develop vomiting some with serious diarrhea some with acute confusion, hallucinations, or delirium and a number with worsening cognitive function. Having patients develop vomiting and diarrhea makes it difficult to know if there is a secondary outbreak in the facility of gastroenteritis. These side effects cause increased work for staff when this happens and are unpleasant for both staff and patients. I would suggest that these medications should no longer be stockpiled or used. This would result in tremendous savings in health care dollars.

Intravenous Vitamin C Alone In Patients With Covid

A pilot clinical trial in China randomized 56 adults with COVID-19 in the intensive care unit to receive intravenous vitamin C 24 g per day or placebo for 7 days. The study was terminated early due to a reduction in the number of cases of COVID-19 in China. Overall, the study found no differences between the arms in mortality, the duration of mechanical ventilation, or the change in median sequential organ failure assessment scores. The study reported improvements in oxygenation from baseline to Day 7 in the treatment arm that were statistically greater than those observed in the placebo arm .4

For adults with low vitamin D levels, the Endocrine Society recommends taking at least 1,5002,000 IU per day.

If youre taking a very high dose all at once, such as more than 40,000 IU, then its possible that side effects may occur due to vitamin D toxicity.

There have been reports of people taking very large doses of vitamin D for months without symptoms, yet blood tests revealed severe hypercalcemia and symptoms of kidney failure .

The harmful effects of vitamin D are very complex. High doses of vitamin D can cause hypercalcemia without toxicity symptoms, but can also cause toxicity symptoms without hypercalcemia .

To be safe, do not exceed the 4,000 IU upper limit without consulting a doctor or dietitian.

Summary

Vitamin D toxicity usually develops over time, and the harmful effects are very complex. Large doses may cause damage, despite a lack of noticeable symptoms.

Don’t Miss: How Much Vitamin C Is Good

Vitamin C In Animals Vs People

As mentioned in a previous blog post, most animals and plants produce their own vitamin C, and only a few cant.

The amount of vitamin C that these animals produce is equal to between 5 and 15 grams per day, if they are healthy. They produce much more when stressed or sick. Up to three times more and some animals produce even more than that.

People must rely on external food stuffs or supplements to get enough vitamin C. Enough vitamin C so that all the body functions that depend on it work in an optimal way and prevent a vitamin C deficiency.

The challenge is that our bodies dont absorb all vitamin C we take. And we can only store very little as a reserve. Also, vitamin C has a very limited short life in the body and lasts only a few hours.

Remember, your body is in constant need of vitamin C. Especially when youre sick or stressed. Any kind of physical or emotional stress.

Heres an interesting study that proves the human body needs more vitamin C when is under stress or sick.

Vitamin D Supplements: What Parents Should Know

How Much Vitamin D Do I Need? SURPRISING

Getting enough vitamin D is essential so kids bones can grow strong and their immune systems can ward off illness.

Vitamin D gets into the body through absorption of sunlight and ingestion of food. From April through the end of October, spending just 15 to 30 minutes outside in the middle of the day with hands and face exposed will stimulate the skin to make all the vitamin D your child needs. In fact, on a sunny summer day, a child wearing a bathing suit can generate 10,000 to 20,000 international units of vitamin D after 15 to 30 minutes. In a neat biological trick, a persons body cant overdose on vitamin D created by the sun.

Foods such as salmon, sardines, tuna, cod liver oil, egg yolks and shiitake mushrooms contain a lot of vitamin D. Many kids dont seem to love these vitamin D superfoods, so luckily store-bought milk is often fortified with vitamin D, as are many cereals and even orange juice. Not all dairy products are fortified with vitamin D, however, so make sure to read the labels.

Routine Vitamin C Supplementation Is Not Justified

A 2013 review of 29 trials which involved more than 11,300 people found no consistent effect of vitamin C on the duration or severity of colds. The only place the authors observed some benefits of vitamin C supplementation was in marathon runners, skiers, and soldiers on subarctic exercise and even in those small populations, the observed effect was small.

The failure of vitamin C supplementation to reduce the incidence of colds in the general population indicates that routine vitamin C supplementation is not justified, the study authors wrote.

And megadoses of vitamin C on the order of 2,000 milligrams or more may come with substantial harms, including raising your risk of painful kidney stones.

If you want to increase your overall vitamin and mineral intake, research backs getting it from fresh fruits and vegetables. This is the best way for your body to process it and ensures you get the most nutrients possible.

Randomized Clinical Trial Of Vitamin D Versus Placebo In Patients With Moderate To Severe Covid

In a double-blind, placebo-controlled randomized trial that was conducted at two sites in Brazil, 240 hospitalized patients with moderate to severe COVID-19 received either a single dose of 200,000 international units of vitamin D3 or placebo.10 Moderate to severe COVID-19 was defined as patients with a positive result on a SARS-CoV-2 polymerase chain reaction test and a respiratory rate > 24 breaths/min, oxygen saturation < 93% on room air, or risk factors for complications. The primary outcome in this study was the length of the hospital stay.

The median length of stay was not significantly different between the vitamin D3 arm and the placebo arm . No significant differences were observed between the arms in the percentages of patients who were admitted to the intensive care unit, who required mechanical ventilation, or who died during hospitalization.

It should be noted that this study had a small sample size and enrolled participants with a variety of comorbidities and concomitant medications. The time between symptom onset and randomization was relatively long, with patients randomized at a mean of 10.3 days after symptom onset. In this study, a single, high dose of vitamin D3 did not significantly reduce the length of stay for hospitalized patients with COVID-19.

Vitamin C Does Not Prevent Colds

How Much Vitamin D Per Day When Sick

âNobel prize winner Dr. Linus Pauling famously claimed in the 1970s that high doses of vitamin C prevented the common cold,â says Mike Sevilla, a family physician in Salem, Ohio.

But Pauling had little evidence to back his claim. The foundations of his argument came from a single study of a sample of children in the Swiss Alps, which he then generalized to the overall population.

Turns out he overgeneralized, and numerous studies have since disproved Paulingâs claim.

âUnfortunately, follow-up research has shown that vitamin C does not prevent the common cold,â Sevilla says. Yet this misconception continues to live on.

âIn my family practice office, I see patients from a variety of cultures and backgrounds and the use of vitamin C for the common cold is well known across all of them,â Sevilla says.

    What Causes Vitamin D Toxicity

    Vitamin D toxicity is almost always the result of excess supplementation. Because your body regulates vitamin D production, you are unlikely to develop it as a result of sun exposure . Foods generally do not contain large amounts of vitamin D, so getting an excessive amount in your diet is unlikely.

    People may begin taking vitamin D supplements in order to address a deficiency or to help relieve symptoms of things like seasonal affective disorder or depression. The problem is that they may go overboard or think that taking more will produce more beneficial effects.

    Our findings support the UK governments recommendation to maintain vitamin D sufficiency all year round, and they show a potentially beneficial role of wintertime vitamin D supplementation.

    It is not possible to get enough sunlight in the UK between October and March, so its advisable to take a 10 microgram vitamin D supplement daily during this period . If you cant get any sunlight at all, or you have not supplemented with vitamin D from October onwards, you may need to take 25 micrograms of vitamin D for four weeks to restore your vitamin D to a healthy level.

    To ensure that you get enough vitamin D during the summer, make sure you get short periods of regular sunlight exposure. Safe sunlight exposure for people living at latitudes between 30 and 60 degrees north involves being in the sun for 15 minutes between 10am and 3pm while wearing a T-shirt and shorts.
