IMPORTANCE OF VITAMIN D

Vitamin D plays an essential role in your overall health, affecting everything from bone strength to immune function. One of the key health benefits of vitamin D is its ability to enhance bone health by promoting calcium absorption, which is vital for maintaining strong bones.

Vitamin D (also referred to as calciferol) is a fat-soluble vitamin that is naturally present in a few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet (UV) rays from sunlight strike the skin and trigger vitamin D synthesis. 

Vitamin D deficiency is a common vitamin deficiency that causes issues with your bones and muscles. It most commonly affects people over the age of 65 and people who have darker skin. It’s preventable and treatable. A deficiency can lead to symptoms such as fatigue, muscle weakness, and increased susceptibility to infections, highlighting the importance of adequate levels.

Seasonal effects can impact your vitamin D levels, especially in winter months when sunlight exposure decreases. The body produces vitamin D naturally when your skin is exposed to sunlight, but various absorption factors—including skin tone and geographic location—can influence this process.

To meet the recommended intake, dietary guidelines suggest incorporating vitamin D-rich foods and considering supplementation options if necessary.

If you’re finding it hard to maintain ideal levels, regular blood tests can help monitor your vitamin D status.

Remember that adequate vitamin D is essential not just for bone health, but also for providing immune support, ensuring you stay strong and healthy year-round.

Estimating Dose-Response Relationships for Vitamin D with Coronary Heart Disease, Stroke, and All-Cause Mortality: Observational and Mendelian Randomisation Analyses

Published in: The Lancet Diabetes & Endocrinology (January 2024)

Objective: To determine whether there is a causal relationship between vitamin D levels (measured as 25-hydroxyvitamin D [25(OH)D]) and the risk of coronary heart disease (CHD), stroke, and all-cause mortality.

Key Findings:

1. Observational Analysis
   
   • Data from 33 studies (500,962 participants) showed that lower vitamin D levels were associated with a higher risk of CHD, stroke, and mortality.
   • This suggested a threshold effect where vitamin D deficiency correlated with negative health outcomes.
2. Mendelian Randomisation Analysis (Genetic Approach)
   
   • Conducted on 386,406 participants from UK Biobank, EPIC-CVD, and two Copenhagen studies.
   • No causal link was found between genetically determined vitamin D levels and CHD (OR: 0.98), stroke (OR: 1.01), or all-cause mortality (OR: 0.99).
   • Even in people with low vitamin D levels, genetic analyses did not support a protective effect of increasing vitamin D levels.
3. Implications:
   
   • The results suggest that simply supplementing vitamin D in people with low levels may not significantly reduce cardiovascular disease or mortality risk.
   • Prior large-scale randomized controlled trials (RCTs) on vitamin D supplementation have also failed to show a benefit.

Conclusion: While observational data suggest an association between low vitamin D and increased health risks, genetic evidence does not support a causal relationship. This indicates that long-term low-dose vitamin D supplementation is unlikely to provide major cardiovascular or mortality benefits.

COVID-19 and Our Understanding of Vitamin D and Immune Function

Published in: Journal of Steroid Biochemistry and Molecular Biology (2025)

Objective: The study examines the role of vitamin D in immune function, focusing on how it interacts with both innate and adaptive immunity, particularly in the context of COVID-19. It explores the mechanisms through which vitamin D influences immune responses and discusses its potential role in combating infections, including COVID-19.

Key Findings:

1. Historical Context of Vitamin D and Immunity:
   
   • Vitamin D’s immunological role dates back to the 19th century when cod liver oil (a vitamin D source) was used to treat tuberculosis.
   • Vitamin D was later found to regulate immune responses in various diseases, including autoimmune disorders.
2. Vitamin D and Innate Immunity:
   
   • Vitamin D enhances antibacterial proteins like cathelicidin (CAMP) and β-defensin-2 (BD-2), which help combat infections.
   • These proteins also exhibit antiviral properties, potentially inhibiting viruses like SARS-CoV-2 by blocking virus-receptor interactions (e.g., ACE2 in COVID-19).
   • Vitamin D may help regulate lung function by reducing inflammation and preventing acute respiratory distress syndrome (ARDS).
3. Vitamin D and Adaptive Immunity:
   
   • The study highlights vitamin D’s ability to modulate T cell responses. It suppresses inflammatory Th1 and Th17 cells while enhancing regulatory T cells (Treg), reducing excessive immune responses.
   • In COVID-19, vitamin D influences T cell activation, potentially reducing severe inflammatory reactions.
4. Vitamin D’s Role in Iron Regulation and Autophagy:
   
   • It suppresses hepcidin, a protein that controls iron levels, preventing excess iron accumulation that can worsen infections.
   • It promotes autophagy, a cellular process that removes pathogens, which could aid in immune defense against bacteria and viruses.
5. New Insights from COVID-19 Research:
   
   • Analysis of COVID-19 patients revealed that vitamin D deficiency correlates with severe inflammation and poor outcomes.
   • A novel discovery shows that complement-activated Th1 cells express vitamin D metabolic enzymes (CYP27B1), suggesting an intracrine (self-regulating) vitamin D system within immune cells.
   • The study suggests that vitamin D supplementation (especially using calcifediol, a fast-acting form) may be beneficial in managing COVID-19-related inflammation.

Conclusion: The study underscores vitamin D’s crucial role in immune regulation, particularly in viral infections like COVID-19. While vitamin D’s effectiveness in preventing infections remains debated, its ability to modulate immune responses and reduce inflammation makes it a promising therapeutic option, especially in acute respiratory diseases.

Published in: Advances in Nutrition (2025)

Objective: The study explores the potential role of vitamin D in tuberculosis (TB) prevention and immune response. It investigates the relationship between vitamin D deficiency and TB susceptibility, considering genetic, immunological, and socioeconomic factors.

Key Findings:

1. Vitamin D and the Immune System:
   
   • Vitamin D regulates immune function, particularly through activation of toll-like receptors and interferon-gamma (IFN-γ), which are critical in TB defense.
   • Deficiency in vitamin D may impair the body’s ability to combat TB infection effectively.
2. Association Between Vitamin D and TB Risk:
   
   • Genetic variations in the CYP27B1 gene (which regulates vitamin D metabolism) may influence TB susceptibility.
   • A study in South India found a link between CYP27B1 polymorphisms and higher TB risk in individuals with lower vitamin D levels.
3. Clinical Evidence on Vitamin D and TB:
   
   • Mixed results were observed in studies on vitamin D supplementation as a preventive or therapeutic intervention for TB.
   • A study in Mongolia with 8,851 children found no significant protective effect of weekly vitamin D supplementation against TB infection.
   • In contrast, a study in India showed that TB prevalence was higher (69%) in individuals with vitamin D deficiency compared to those with sufficient levels (52%).
4. Social and Economic Influences on Vitamin D Deficiency and TB:
   
   • Lower socioeconomic status (SES) correlates with higher TB rates due to reduced sunlight exposure, poor nutrition, and limited access to healthcare.
   • Studies in Portugal and Ireland found that children from wealthier families had higher vitamin D levels due to increased outdoor activity and access to supplements.
5. Vitamin D and Latent TB:
   
   • A study in Spain suggested that adequate vitamin D levels might protect against the reactivation of latent TB.
   • Seasonal variations in vitamin D levels influenced active TB cases, with lower vitamin D levels observed in winter months.

Conclusion: The study highlights a possible link between vitamin D deficiency and increased TB risk, particularly in low-SES populations. While vitamin D plays a role in immune defense against TB, evidence on supplementation as a preventive measure remains inconclusive. Further research is needed to establish whether improving vitamin D status could be an effective public health strategy against TB.
