1. Under Our Skin
IMDb Rating: 8.3
The last documentary on our list of 11 best health documentaries on YouTube follows the corrupted and profit-hungry healthcare system in the United States, but from a whole different perspective. When a system that should be taking care of your health says “your symptoms are just in your head,” and is failing to recognize Lyme disease as one of the fastest spreading epidemics of modern times, there isn’t a lot you can do but to make a documentary and hope it will make even a slight difference.
