I started buying this supplement awhile ago, mostly due to the great reviews that this brand has. I've been on and off the ketogenic diet, as well as battling intestinal candida, so this supplement has helped so much for both. When the candida has nothing to feed it (sugar, carbs, yeast, etc) loads of toxins are released, which can overload the organs, especially the liver, and cause a multitude of symptoms. I've found that this supplement helps during those times, since when I haven't taken it, I would sometimes get aching pain in the area where my liver resides, as well as overall feeling really sick. I also like that this brand's milk thistle is highly concentrated, as other brands don't even specify the percentage of the flavonoid silymarin they contain. For the price, the reviews, the ingredients list, and the experience I've had taking this product for a long period of time, I highly recommend
