On a monthly basis I review the complaint sites for "non mainstream products". I've found the same pattern amongst posters: some love it, some hate it, some feel it's served its purpose.
That's what we get from every dietary/weight loss or health product. There are some requesting research, well the truth about research is that most people don't understand the statistical analyses employed to convey the result nor what it really means. How many FDA-approved products have been found harmful after millions were prescribed some type of pill? Consumers and patients are a,ways at the mercy of research results.
Every time we ingest something, it's an experiment. Heck, more and more people are allergic to "natural foods" such as peanuts, tree nuts, milk, eggs, strawberries, shellfish, etc... We are all different. I'm also not concerned with the direct marketing that so many people seem to be mad about.
Many of these people are their own "GNC or Vitamin Shop"...why is that bad? Mary Kay and Avon have done the same things for years. And guess what, not all of their products deliver the result they advertised for everyone. You'll also see people posting about how mad they are that they joined and didn't make money.
I advise people to NOT be dissuaded by posts to take or use these products. I'm not a regular customer, but I did lose 17lbs when I did the 24Day Challenge. I'm not a sucralose fan, but I try the drinks here and there. The truth is, there's not much you can buy anywhere anymore that doesn't have some of these same ingredients unless you're talking about buying ONLY whole foods.
You can't buy anything from the middle of your grocery store anymore without some kind of "compound".
This isn't an endorsement or disuasive review. Just some insight.
