Because I have tried other products and have been totaly lied to! Once I was suckered into buying a bottle of Oregano Oil that was supposed to be Authentic and 100% Pure! Boy was that a joke! It tasted more like Basil! And it was very mild. True Oregano oil from the Mediteranean is extremely hot! I find that Now brand is the best for the money it seems. I paid $27.00 for a bottle of Oregano Oil that was about 90% Olive Oil! I will never do that again! The Now brand is more pure and less expensive! And its not just the Oregano Oil; but their Vitamins, herbs and other essential oils are some of the best you will find for the price! I have a bottle of their C-1000 Complex (Buffered C) and it works great!
Well that could be like me saying "If you didn’t like what I was saying; why answer? If you think its a dumb question than don’t answer! You ever think that mabe I just want to see if anyone else feels the same way I do about the product?

I’ve tried a few vitamin companies too. I look for the list of ingredients and the sources of the ingredients. Get referrals from friends for products. If it worked for them it might work for you too. Find a vitamin store that has a knowledgeable owner. This can be a great source of information. In the long run the proof is in the pudding. If it works for you, then your are getting the best product.
I’ve bought products in the past that had no effect for me. They went in the trash can. When I find something that works I keep buying it.
I have no idea what Now foods is or what’s in it. I would have to look at the label to tell you.
