I prefer to read published studies. With a video you can't understand the underlying data.
If the study is published, has proper clinical setup I will be willing to read it, and if it shows benefit then I will accept it.
I understand that trials are underway with respect to as a preventative.
It could work, I hope it does.
I am all for definitive information, however with science I acknowledge that people have to work with what is known at the time.
I fully understand that if you don't have an effective treatment then you need to try something. And a combination of therapies will most likely be the answer.
