Vitamin D - Master regulator of multi-role Serotonin (in both Brain and Gut)

In this fascinating conversation, Dr Rhonda Patrick outlines her recent research on the link between vitamin D, serotonin and autism. Vitamin D controls, at a very minimum, 5% of the human genome. This talk focuses on the role of vitamin D as a regulator of serotonin; damping serotonin's potentially over-active immune function in the gut, while activating serotonin's beneficial management functions (such as long term planning, impulse control, anxiety management and sensory gating) in the brain.

Serotonin plays a profound role in brain morphology and development and vitamin D regulates serotonin. So, if mum uses too much factor 50, that UVB doesn't make vitamin D and baby doesn't get enough serotonin and ... well, you can see where this is going.

Here's Dr Patrick to, as the Beach Boys might say, help us (Rhonda, help, help us Rhonda). We'll skip the pleasantries and get right into it:
