I purchased this because I learned that I am deficient in manganese, and when I looked up how I'd have to modify my diet there is just no way that I would ever eat that much, so I went on the hunt for a product that included it. I selected this one because it also has minerals that I usually take separately, as well as some choline and inositol. So, to my mind I thought that despite the price of this supplement, I'd be able to save on not taking those. The main symptom of the manganese deficiency is some joint swelling, pain and a rash. I did get some improvement in those first two after a few days of taking this. However, now that I have looked up the RDA and UL for manganese and the other minerals, I realize that this is just too weak. Taking more than is directed is not an option due to the 7-Keto ingredient, plus that would make this last a week instead of a month. I can't say whether the 7-Keto would make any difference, and weight loss wasn't my primary objective. I still looked it up before taking this, because we should always know what we are taking. There is research support for that ingredient. I haven't dropped a size in a week or anything, lol, and have not noticed any indication that my metabolism is any different. I still need the same number of blankets, etc. If you are looking for the minerals, too, then there are stronger formulations available at a much more reasonable price point.
