So many comments on here are merely naive optimism when we should all have a healthy scepticism about everything. We all want simple, easily accessed nutrients to cure everything, but it doesn't happen like that regardless of what a manufacturer, Naturopath or Doctor may tell you. The only truth is a proven truth so look for truth in science.
We should all be sceptical of everything regardless of how many people believe in it, even science, because hardly any truth has ever turned out to be completely true.
From politicians, authors, scientists (climate change and health are prime examples) to manufacturers some untrue statements are deliberately presented as facts, when in actual fact they are not, and the perpetrator of this misleading information often knows that they are spreading lies, for personal gain or some other reason.
I could sell Canada to some people on here, I don't own it, but I would bet some people would attempt to buy it.
