Everyone has to make their own choices. I'm not big on any supplements-natural or not. Heck, other than antibiotics I really hate any meds and even antibiotics I avoid because I want them if I'm super sick or a limb is in danger of being amputated.
Because there's no regulation-kind of puts it in the same basket as illegal drugs, you never know what's in them.
OTOH, if you find a company you trust, make your choices.
