Rated 4.9 out of 5 by 85 reviewers.
Rated 1 out of 5 by Bad Batch, Rancid odor I've never experienced any negative odor before with milk thistle, but as soon as I opened this bottle, I was hit with a strong, rancid oil smell. Maybe it was a bad batch, maybe the box it was in got too hot during shipping (April weather-- it really wasn't that hot), but my guess is that somehow a bad batch slipped past Quality Control. -- Manufacture date: 02/16. May 3, 2016
