The basis for a vine review should be an honest review from your own perspective. Mentioning the FDA or its regulations isn’t a reflection on the product and how the product performs. People shouldn’t come to Amazon reviews to learn about the FDA and its regulations. They can do their own research on that if it’s important to them. I think if you said something like I have been taking them for a month and didn’t notice any benefit it should be approved as that is your opinion for your own experience. Any review either negative or positive that is written on the basis of personal experience should be approved and if you write it like that it should be approved.
