I do not sell supplements but definitely disagree with you.
People all over the world are nutritionally deficient and the result is shortened lives as well as direct loss of life.
You said "Yes, supplements are helpful but far overrated with human nutrition."
It is sad that you do not realize that a major cause of miscarriages is not having sufficient selenium.
The main cause of coronary problems, including strokes and heart attacks is insufficient vitamin C and B3.
There are many deficiencies that have not yet been discovered or defined. This is one reason while our average life span is only 80 or so when it could be easily 100 to 120 years.
I do agree that most supplements sold are junk because many of them do not contain real vitamins but only substitutes.
