At the risk of gibing away my age, I remember when pharmacies didn't offer much more than the filling of a prescription from my doctor. There were always a few sundry items on the shelves by not like today! And health food stores? Those usually offered some mysterious supplements while incense burned and sitar music played in the background. Today, supplements have become mainstream and new ones seem to pop up almost weekly. We find them in our supermarkets ans pharmacies ans are overwhelmed by them at the health food stores. Every company has something 'better' or 'new and improved'. It can be a difficult to make sense of any of it at the best of times. Even more confusing is the information that we try to gather when, in fact, not very much is known about some of these items.
