We adopted a lovebird with Fatty Liver disease; it was recommended to us that we get him a Milk Thistle product with no alcohol. Have you ever tried finding milk thistle extract without alcohol? Locally, it's impossible. After going to one health food store after another, I could not find any of them that were suitable. And $11 or more a bottle, besides that.When I found this product on Amazon plus S&S, it was a miracle! And this product works great. I do not use this for people, just on my pet, so my review is pet-specific.Don't dose a bird directly with this product. Don't put it in their water either, unless you monitor them. My lovebird stopped drinking his water because of the taste of this product in it. So, I had to buy Avi-Cakes. We had weaned my bird off seed (the cause of his fatty liver disease) but he's still a seed craver, so the AviCake was the perfect solution. It's 50% seed and 50% pellet, I soak a square (the equivalent to about a teaspoon of seed/pellets) every morning with about 6 drops of the Milk Thistle extract, and I know he gets some of this every morning that way. Not enough seed to exacerbate his liver disease but definitely he is getting therapeutic benefits from the product. He is 11 this year, and we've had him 3 years. He had fatty liver disease before we got him (who knows how long) and he really should not still be alive, but he is! And he's healthy. Since starting the milk thistle two years ago (i used another brand that became unavailable) he has had a dramatic increase in feathering. Before, all his growth went into the massive beak he was growing due to the fatty liver disease.I love this milk thistle product, it works!!UPDATE 06-2013: He's now been on milk thistle for four years, and last year his beak growth changed. When we got him, he had this MASSIVE thick top beak that just would not stop growing. Now, the top beak growth is normal. It's just his BOTTOM beak that grows now, but it's not huge and thick like the top beak. We have to have his bottom beak trimmed 2x a month (nowhere near normal for a healthy bird in case you wonder). But, his feathering is like a normal bird now and his toenails even grow normally as well. (Before, they hardly grew, and he had poor feathering. EVERYTHING went into making that huge honking Jimmy-Durante beak!) He's 12 this year, he's had fatty liver for four years (no doubt longer) and he is active, bright-eyed, and healthy. I was able to start adding the milk thistle to his water at long last, but it took years of trying before he would accept it in his water.
