Douglas Laboratories L-Ornithine 500 Mg
I have several genetic mutations that affect ammonia breakdown, but I had read that Yucca and L-ornithine can break down ammonia. I took Yucca root for quite a while but found it that it is highly estrogenic, so I switched to L-ornithine. It knocks out the symptoms of excess ammonia perfectly, and it doesn't have the side effect of being estrogenic like Yucca does. This is a winner for me, and I continue to use it. I take one a day.
