Once known mainly for its role in bone health, vitamin D is now emerging as a key player in gut health and immune function.
🧬 Low levels of vitamin D have been linked to serious GI conditions like Inflammatory Bowel Disease (IBD), diverticulitis, colon cancer, and liver disease. Vitamin D deficiency affects over 40% of the U.S. population, with even higher rates in African American (82%) and Hispanic (63%) communities. So why does it matter?
🔬 Vitamin D helps:
✔️ Regulate inflammation
✔️ Maintain the gut barrier
✔️ Support a diverse and stable gut microbiome
✔️ Interact with immune cells via vitamin D receptors in the gut
💡 Emerging research shows that vitamin D supplementation may positively shift your gut microbiome — increasing microbial diversity and protecting against disease.
