I have taken it. I did a bunch of other stuff at the same time so I can't say I felt anything differently, but it really is one of those supplemetns that I am not sure you would feel much of anything. I think you would notice your skin being more clear, more vibrant. But I did it during and after extensive colon cleansing which clears the skin as well. Hard to say but it is a good source of Omegas, fiber and even protein.
