After trying many different milk thistle products finally a supplement that my horse will take in his food to help him with his high liver enzymes. It’s a great product at a fabulous price.

Using for my EMS horse on medication. Recommend my your nutritionists who helped me come up with a plan. Which has really helped my horse feel better.

I do like this product, I just wish they sold it in a bigger packet as I go through it quickly.

Just started my chestnut pony on the milk thistle seed to help with her itching due to allergies, the itching seems to have improved.
