Intensive Nutrition Has Closed
I really like this supplement and that it is a lozenge, but I was told by the supplier I had been buying it from had closed in Dec 2019; the company's Twitter page says "After 50+ years in the industry, it is time for us to say goodbye."  I checked the imprint of the bottle I purchased in May of 2021; it has a manufacturing date of Jun 2019 -- so it was nearly 2-years old when I received it.  I don't know what the shelf life of this product is, though it seems OK.  Perhaps it is stable and still safe to take.  Just FYI.
