Question about DHC supplements

I wanted to ask if anyone here has experience with DHC supplements.

And I have two questions:

  1. I’ve heard that Japanese locals generally think DHC is a pretty low-quality brand. Is the product really bad? If so, are there any references that I could fact check ?
  2. I’ve been taking their liver support tablets, but recently I noticed the pills have a very strong, unpleasant smell. I don’t remember noticing it before (maybe I just didn’t pay attention in the beginning). For those of you who also take this product, is this smell normal?
