I purchased this product based on the fact that it was the only product of it's kind that passed Consumer Labs.com's potency and purity tests. All of the other brands failed. It has helped my liver enzymes return to normal. I had used other brands for the past 4 yrs, however they did not work for me. It pays to use Quality supplements. I only wished that i had researced this before using worthless products for those 4 yrs.
