SILYMARIN INFORMATION:
If your veterinarian recommends a smaller dose of milk thistle, those dosages are often based on milk thistle concentrated extract.
Our milk thistle is whole ground seed, which contains 5x more volume than concentrated extract. While our daily recommendations are higher, they provide a comparable amount of active ingredient (3%) needed to be effective.
