Low Vitamin D
The recent news linking low vitamin D to COVID-19 has turned many heads including my own. It's left many of us wondering about our own levels and adequacy. Some of the most salient points in the scientific literature on vitamin D and COVID include: 1. 80% of COVID cases are vitamin D deficient.[1] 2. Risk of testing positive for COVID is 77% higher in those with low vitamin D levels.[2] 3. Low vitamin D may be linked to high inflammation and increased severity of COVID.[3][4]
