I was nervous about taking vet meds, too, but I can say that I haven't had any trouble with the Valbazen. I took it for about two weeks and did really well, except my blood pressure did shoot up which was very abnormal for me. My digestion went from horrible to amazing in just a few days. I started having some trouble again a few days ago after a Liver Flush (but my blood pressure did drop back to normal), so I restarted the regimen. I am not going to do the 40g of fat this time because I gained about five pounds. Just taking a tsp after breakfast and dinner. Feeling better already (digestion) after day 2. The only thing bothering me now is upper back discomfort. Sometimes it feels as if pins are sticking me in the back and right side under my rib cage. I have some twitching in the same areas in the morning when I wake up and stretch. I haven't experienced hair loss.
