Vitamin D may reduce the risk of developing cardiovascular disease

Vitamin D may reduce the risk of developing cardiovascular disease and cancer. However, few large, higher-quality randomized controlled trials (RCTs) have been conducted to corroborate this. A recent RCT examined the effects of vitamin D supplementation in Finland. It found no association between vitamin D and reduced risk of cardiovascular disease or cancer. There is evidence that vitamin D deficiency is associated with nearly all primary chronic conditions, such as cardiovascular disease, cancer, type 2 diabetes, and mortality.

It looked at data from 2,495 people, including those with no cardiovascular disease or cancer history. To provide further evidence of the relationship between vitamin D, cardiovascular disease, and cancer, the researchers behind the present study conducted the Finnish Vitamin D Trial. Despite the large doses, the study failed to see any effect of the supplementation on lowering the incidence of [cardiovascular disease] and cancer. Those who might benefit from the vitamin D supplementation — i.e., those with low serum vitamin D levels — are a small minority in the trials. Prof. Karani: “High-dose vitamin D supplementation may modestly reduce the risk of cancer death, but not overall cancer incidence.” Dr. Virtanen states, So far, there is no evidence that [Vitamin D] supplementation could prevent [SARS-CoV-2] infection. Still, it is well-documented that those, especially with the severe form of COVID-19, have low serum vitamin D levels.

It is also possible that this is a consequence of the [SARS-CoV-2] infection rather than the cause because it is known that acute infection leads to lower serum vitamin D levels. In addition, many of the COVID-19 patients are overweight or obese or have a chronic disease like type 2 diabetes, which is associated with lower serum vitamin D levels, explained Dr. Virtanen. “It is challenging to obtain vitamin D from food intake alone unless that food is fortified with vitamin D. It would be essential to explore whether vitamin D supplementation can decrease the incidence of [cardiovascular disease] and cancers, as that would make a strong case for mandatory vitamin D fortification or promotion of fortified foods in the population.

Fast-spreading Omicron variant

A fast-spreading Omicron variant that causes milder illness compared with previous versions of the coronavirus has fueled the view that COVID-19 poses less of a risk than in the past. For those who do have symptoms, a higher proportion experience very mild illness, such as the sore throat or runny nose without the breathing difficulties typical of earlier infections.

Covid-19 Testing

Omicron is the fifth highly significant variant of the original SARS-COV-2, and it remains to be seen if the ability of the virus to mutate further will slow down. In fully vaccinated and boosted individuals without underlying medical conditions, Omicron “will not do too much damage,” said David Ho, professor of microbiology and immunology at Columbia University.

Omicron-specific vaccination

According to the Centers for Disease Control and Prevention, Omicron accounted for more than 95% of all new cases in the United States last week. The representative verified that the production of doses of the Omicron-specific vaccination has already commenced. Symptoms of COVID-19 and the Omicron variant: Recent investigations indicate that Moderna Pharmaceuticals is working on an Omicron-specific variant vaccination. Moderna anticipates initiating advanced clinical studies for the vaccine early this year but did not say when. Dr. Anthony Fauci, the White House’s senior medical advisor, has recommended that Americans obtain booster injections, which are 75% effective at avoiding symptomatic COVID-19 infection.
Stéphane Bancel, CEO of the pharmaceutical company Moderna, said last week that he expects the current vaccine’s protection to fade. Moderna said on Monday in a website update that although the pharmaceutical company’s first line of defense against Omicron is a third dosage of its current vaccine, it is also creating an Omicron-specific booster injection.
Pfizer says its vaccine targeting Omicron will be ready in March.
