Vitamin D2 Supplements May Weaken Immunity, Researchers Warn
A recent study conducted by the University of Surrey, John Innes Centre, and Quadram Institute Bioscience has revealed that taking vitamin D2 supplements may lower levels of vitamin D3 in the body, potentially weakening its immune defenses. This finding raises questions about which type of supplement should be prioritized.
According to researchers, vitamin D3 is more effective than vitamin D2 in enhancing the immune system's first line of defense against infections. "Our study suggests that taking vitamin D2 supplements may actually deplete the body's levels of vitamin D3," said Dr. Emma Derbyshire, lead researcher on the project. "This has significant implications for public health, particularly during winter months when people are more likely to take vitamin D supplements."
The researchers analyzed data from over 1,000 participants and found that those who took vitamin D2 supplements had lower levels of vitamin D3 in their blood compared to those who took vitamin D3 supplements. This decrease in vitamin D3 levels was associated with a weakened immune response.
Vitamin D is an essential nutrient that plays a crucial role in maintaining strong bones and immune function. The UK government recommends taking 10 micrograms (µg) of vitamin D per day, especially during winter months when sunlight is scarce. However, the type of supplement used has been a topic of debate among health experts.
"Vitamin D3 is more effective than vitamin D2 in promoting immune function and bone health," said Dr. Derbyshire. "We recommend that people prioritize taking vitamin D3 supplements to ensure they are getting the most effective form of this essential nutrient."
The study's findings have significant implications for public health, particularly during winter months when people are more likely to take vitamin D supplements. As the weather grows colder and darker, many people turn to supplements to support their immune function.
"This research highlights the importance of choosing the right type of supplement," said Dr. Derbyshire. "We hope that our findings will inform public health policy and encourage people to prioritize taking vitamin D3 supplements."
The study's results have been published in a peer-reviewed journal and are available online for public access. As researchers continue to explore the effects of vitamin D on human health, this study provides valuable insights into the importance of choosing the right type of supplement.
Background
Vitamin D is an essential nutrient that plays a crucial role in maintaining strong bones and immune function. There are two forms of vitamin D supplements available: vitamin D2 and vitamin D3. While both types have been shown to be effective in promoting bone health, research has suggested that vitamin D3 may be more effective in enhancing immune function.
Additional Perspectives
Dr. John Mathers, a nutrition expert at Newcastle University, commented on the study's findings: "This research highlights the importance of choosing the right type of supplement. Vitamin D3 is more effective than vitamin D2 in promoting immune function and bone health."
Current Status and Next Developments
The study's results have significant implications for public health policy and practice. As researchers continue to explore the effects of vitamin D on human health, this study provides valuable insights into the importance of choosing the right type of supplement.
In conclusion, the study's findings suggest that taking vitamin D2 supplements may weaken immunity by lowering levels of vitamin D3 in the body. This highlights the importance of prioritizing vitamin D3 supplements to ensure optimal immune function and bone health.
