well i was asked to write a review for a promo. however i bought this product and also liposomal glutathione together because research said that they were both bio available, but the distinction between the 2 is that liposomal is for gut health and sag is probably more for metabolic/systemic health. which i don't quite clearly understand what that means. the liposomal made me move my bowels 100%. but i'm not sure what benefit sag had on me, but i have yet to give it a chance to find out. note that the liver is a producer of glutathione. and although i was not having any specific problems but i wanted this as part of my arsenal. it may actually be good for liver damage such as cirrhosis of the liver, for alcoholics , ascites, and maybe leaky gut, etc.. please do your own research, AI offers a lot of info with the opportunity to ask a lot of questions. the key to finding out the difference between the 2 is to take them separately and apart from each other, take one or the other.
