In this episode of Patient Pulse, Dr. Clifford Rosen, Professor of Medicine at Tufts University School of Medicine, talks about the role of vitamin D in heart, lung, and related diseases.
Dr. Rosen explains myths and realities about:
- How Vitamin D works
- Vitamin D levels and bone health
- Vitamin D and acute and chronic diseases, including heart disease, cancer, obesity, blood clots, and COVID-19
- Vitamin D treatment for acute and chronic diseases
- Vitamin D is made in the skin and is also absorbed orally.
- Vitamin D promotes calcium absorption in the gut.
- Generally healthy levels are between 15-45 ng/ml; levels may vary due to skin color, dietary intake, obesity, or chronic disease.
- Serum (blood) vitamin D levels do not predict chronic diseases.
- Vitamin D treatment has not been shown to impact any acute or chronic disease, including heart disease, blood clots, or inflammatory conditions (COVID-19).
- 800 IU vitamin D is sufficient for most individuals.
