This is the first edition of #WeAreReading EXTRA. This series will run concurrently with the regular weekend streams and will share everything I'm learning about science and health. My main aim is to disseminate information that you can consider in your overall approach to health and wellbeing. 

The first topic we'll be covering is Vitamin D. Follow a recent health issue, I've I've been devoting most of my spare time to understanding my health. And this has led me to Vitamin D. As I'm studying, I'm becoming more convinced that insufficiency and deficiency in Vitamin D is a critical health issue across the global North. This applies to everyone, but especially darker-skinned people including Africans.
