I am HIGHLY sensitive to many supplements. I have tried a few other popular Grass-fed beef liver brands and have had reactions to them. Dr Ron's is the only one that I have tried that I do extremely well with and have had incredible success with. I have virtually no PMS since taking 3 capsules per day for 2 to 3 months, and my skin, energy, nails and mood have all improved. Can't say enough good things about this product. THANK YOU!!

I have tried other brands of this food-based supplement before and none of them compare. Dr. Ron made the effort to make sure the quality of this product was unparalleled, and he succeeded at that. I even have had a different brand make me feel ill before. Dr. Ron's organ products are my standby for any animal-based products I may need or recommend to a client. Most other products on the market in this category have way too low of standards. May his company continue to never compromise quality over profits. As I told Dr. Ron once in an email, my kitty, Gordon, prefers this product over any other on the market too and I trust his instincts the most. It helps keep him strong and healthy.

I have been taking this liver supplement for a little while now and it's just great. I can feel the difference in my eyes from the high Vitamin A content. The product is very high end, potent, and fresh. I like the fact that it is sourced from New Zealand bovine since the environment there is very clean. And it's additive free which is great as well. Easy 5 stars. Highly recommended.
