In this book, the author repeatedly states that 45 milligrams of vitamin K2 equals 4,500 micrograms. I thought 1 mg = 1000 mcg. How could this be?
This is a typo. In the text he states:
... only 0.120 milligrams (120 micrograms) of MK-4 ...
So, he knows the correct conversion.
... the "same" product is almost 40 times more potent in one country ...
40 times 120 micrograms is 4800 micrograms -- which is close to 4500.
So, that suggests that the
(4,500 micrograms) in the table is correct and that the
45 milligrams is a typo.
It should read
