How to make COVID vaccines more effective: give people vitamin and mineral supplements

/ SupremeCmdr / Leave a comment

For the immune system to fight off infection or generate good protection against a disease following vaccination, it needs a variety of micronutrients. This is likely to be just as true for COVID-19 as for other diseases. Given that malnutrition is common among elderly people, raising their vitamin and mineral levels before they get vaccinated could be a way of boosting the effectiveness of COVID-19 vaccines.

In patients hospitalized with COVID-19, calcifediol treatment at the time of hospitalization significantly reduced ICU admission and mortality.

Take Vitamin D supplements. Let the experts debate this until the end of time. See Does Vitamin D Deficiency Raise COVID-19 Risk? – JAMA. And as the debate rages, take your vitamins.

Does Vitamin D Deficiency Raise COVID-19 Risk? – JAMA

/ SupremeCmdr / 1 Comment

Despite Fauci’s recommendation and claims by many supplement sellers, conclusions about vitamin D blood levels’ connection to a host of diseases, including infections, cannot be determined because of mixed or sparse evidence, according to a recent report written for the US Preventive Services Task Force, which is updating its recommendation on vitamin D deficiency screening. The draft updated recommendation, like its 2014 predecessor, concludes that the evidence is insufficient to assess the benefits and harms of screening in asymptomatic adults for any reason.

The comments to this JAMA article are as educational as the article itself.

But as the debate rages on, I’ll continue to take 1000iu D3 daily. It can’t hurt.

Vitamin D Deficiency Is Inversely Associated with COVID-19 Incidence and Disease Severity in Chinese People

/ SupremeCmdr / 3 Comments

In the general linear model adjusted for age, sex, comorbidities, and BMI, serum 25(OH)D concentrations were significantly lower among COVID-19 patients than the 2018–2019 controls [ln transformed values of 3.32 ± 0.04 vs. 3.46 ± 0.022 ln (nmol/L), P = 0.014]. Multivariable logistic regression showed that male sex (OR: 2.26; 95% CI: 1.06, 4.82), advanced age (≥65 y) (OR: 4.93; 95% CI: 1.44, 16.9), and vitamin D deficiency (<30 nmol/L) (OR: 2.72; 95% CI: 1.23, 6.01) were significantly associated with COVID-19 severity (all P < 0.05).

These findings suggested that vitamin D deficiency impacts COVID-19 hospitalization and severity in the Chinese population.

I am hoping all of my Chinese relatives read this.

Vitamin D and Calcium Reduce Incidence of Recurrent Vertigo (BPPV)

/ SupremeCmdr / 2 Comments

The multi-center study included 957 people in South Korea with benign paroxysmal positional vertigo who had undergone canalith repositioning maneuvers—head movements that shift displaced calcium carbonate crystals in the inner ear. The intervention group included patients who received 400 IU vitamin D and 500 mg calcium carbonate twice daily for 1 year when their baseline serum vitamin D level was below 20 ng/mL along with patients who had higher baseline levels and took no supplements. An observation group had no baseline testing or interventions.

The supplements significantly reduced the annual vertigo recurrence rate by 24%. There were 0.83 recurrences per 1 person-year in the intervention group compared with 1.10 in the observation group. Patients with greater vitamin D deficiencies at baseline derived the most benefit.

BPPV = benign paroxysmal positional vertigo. The original study in Neurology and the JAMA summary both use the word “prevent” in their respective titles. I think reduce is a more apt description. Semantics aside a 24% reduction in recurrent BPPV episodes is significant.

And yet another example of nutritional deficiencies underlying another disease.

Vitamin B12 Breakthrough for more complete Vegetarian and Vegan diets

/ SupremeCmdr / Leave a comment

Vitamin B12 (known as cobalamin) is an essential dietary component but vegetarians are more prone to B12 deficiency as plants neither make nor require this nutrient.

But now a team, led by Professor Martin Warren at the University’s School of Biosciences, has proved that common garden cress can indeed take up cobalamin.

The amount of B12 absorbed by garden cress is dependent on the amount present in the growth medium, and the Kent team was able to confirm B12 uptake by showing that the nutrient ends up in the leaf.

I can’t wait for the silly money and marketers to grab this and run.
