Thanks for those enzymes -- I'll pass them along to my SIL.
For sure, supplements deal with very personal results and scams need to be outed because of the possible consequences. This applies to everything -- even that car oil -- knowing nothing about these things, I just put in what is recommended and if it is defective, my adorable car's engine would be wrecked. It applies everywhere.
It is discouraging that one now needs to be an expert on every area of our own lives so that we use the best products -- exhausting really -- simpler is better. :)
