Pros

Began taking 2/dayafter reading most folks are difficint esp in the north and during winter months. It really helps. Prescribed by doctor. And it's unlikely to hurt you if the initial observations on inflammatory response to covid don't pan out.

It is convenient that amazon offers them. The pricing is fairly competitive with other brands. We like that it comes in economical amounts. Had been purchasing from store.



Cons

The cheap often becomes expensive! Who needs all the other garbage?
