I should be more clear MSG does have side effects I didn't mean to imply that it doesn't. But yea my point was that side effects are also possible with things in dietary supplements, bad example though.

Also I should say that not all supplements are BS. Some really do work but mostly for minor every day ailments. If you have serious medical conditions sometimes they also can help (some people do have dietary deficiencies or metabolic deficiencies that can be fixed with vitamins etc).

But yea basically what I am trying to say is be aware that a lot of information out there is hype and marketing. There are good products and there will be good products in the future but that will only happen if consumers are informed and make the right choices and support the right industries/research.
