Yep. Was just gonna say, lots of tbings do amazing things in vitro... problem is... to replicate that in human nodies, it would take amounts so massive it would kill a person.
In vitro is an environment where a massive amount of a product, (usuzlly vitamins, or substances such as natokinase) overwhelm vulnerable cells like cancer cells and kill em en mass, howver, to get that same effect in humans would take likely lethal or dangerous amounts. (Not in all cases, but in many)
