    slight change in formula, can't take now
  

*by W***L on Reviewed in the United States on July 18, 2024*

I've been taking this for years, but this time it's in a new bottle and the company is now SFI Health. It now has a flavoring I can't tolerate.  No returns on this item.  I'm sure most people will be fine with it. It's frustrating I can't return it.
