🏥 Health & Wellness Vitamin D COVID-19 Supplementation Research Updates
  1. Generalizing effects of vitamin D on colds and flu to COVID-19 may not be accurate due to differences in viral mechanisms and effects on ACE2 receptor.
  2. Increasing ACE2 with vitamin D in COVID-19 could potentially enhance viral growth due to exponential replication, leading to more harm than benefit.
  3. Maintaining a conservative approach towards vitamin D supplementation for COVID-19, ensuring not to induce deficiency, finding lowest effective dose, and monitoring levels between 30-40 ng/mL.

🏥 Health & Wellness Vitamin D Cholesterol Nutrition Toxicity
  1. Vitamin D is synthesized from cholesterol in the body, and it can also be obtained from cholesterol-rich foods.
  2. Sunlight exposure is crucial for the synthesis of vitamin D in the skin, but factors like latitude, time of year, and atmospheric conditions can affect this process.
  3. Cholesterol-rich foods, like cod liver oil and fatty fish, are among the richest dietary sources of vitamin D, highlighting the importance of consuming both vitamin D and cholesterol for optimal health.

The First Vitamin D Study With Pre-Infection Levels Weakens the Association

Harnessing the Power of Nutrients • 0 implied HN points • 14 May 20
🏥 Health & Wellness Vitamin D COVID-19 Infection Risk Nutrition Research Updates
  1. The first study with pre-infection vitamin D levels weakens the association with COVID-19 risk.
  2. Maintaining a vitamin D level of 30-35 ng/mL may reduce infection risks by 42%.
  3. The study suggests a weak association between pre-infection vitamin D status and positive COVID-19 tests.

Vitamin D: The First Study on COVID-19 Infection Risk

Harnessing the Power of Nutrients • 0 implied HN points • 09 May 20
🏥 Health & Wellness Nutrition COVID-19 Vitamin D Infection Risk Research
  1. The first study on the association between vitamin D status and COVID-19 infection risk was published, providing valuable insights.
  2. Previous studies showed vitamin D status below 30 ng/mL is linked with more severe disease or mortality in COVID-19 patients from various regions.
  3. Results from the new study suggest maintaining 30-35 ng/mL of vitamin D may help protect against infection risk, particularly for those over 70, but more research is needed.

Two New Vitamin D Studies

🏥 Health & Wellness Vitamin D COVID-19 Research Updates Prevention
  1. Vitamin D status below 30 ng/mL is linked to severe disease and mortality in COVID-19 patients from South Asian and Southeast Asian hospitals.
  2. New studies show the association between Vitamin D and COVID-19 severity extends beyond South and Southeast Asia, even to Europe.
  3. Maintaining 25(OH)D close to 30 ng/mL is still recommended, despite new insights from the recent studies.

Update on Vitamin D and COVID-19 Using the First Observational Study Released

🏥 Health & Wellness Vitamin D COVID-19 Immune System Inflammation Preventative Care
  1. Maintaining vitamin D levels within 29-34 ng/mL may lead to less severe COVID-19 outcomes.
  2. The relationship between vitamin D and COVID-19 severity is complex and may involve factors like IL-6 levels and lymphocyte counts.
  3. It is important for physicians to test and assess the impact of correcting low vitamin D levels on COVID-19 outcomes.

Vitamin D Does Not Explain the Race/Ethnicity-COVID-19 Relationship

Harnessing the Power of Nutrients • 0 implied HN points • 26 May 20
🏥 Health & Wellness Vitamin D COVID-19 Medical Research Infection Risk
  1. Vitamin D levels below 20 ng/mL increase infection risk, but this association disappears when adjusted for various factors like ethnicity and health conditions.
  2. Race and ethnicity are strongly linked to COVID-19 risk, even when accounting for vitamin D levels. Genetic factors are likely more influential in this relationship.
  3. Maintaining vitamin D levels between 30-35 ng/mL seems to be the optimal range for minimizing severity, mortality, and infection risk, based on current research findings.

Five New Vitamin D and COVID-19 Studies

🏥 Health & Wellness Vitamin D COVID-19 Research Studies Clinical Trials
  1. Genetic studies on vitamin D and COVID-19 are inconclusive, showing no clear causal link.
  2. There is potential for a U-shaped curve in the relationship between vitamin D levels and COVID-19 risk, with optimal levels between 30-40 ng/mL.
  3. Maintaining vitamin D levels above 30 ng/mL is associated with lower COVID-19 risk, severity, and mortality, with clinical trials underway to provide more clarity.
