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?

6$\begingroup$ It's a typo. 1 mg = 1,000 mcg. $\endgroup$ – MattDMo Aug 23 '15 at 14:06

1$\begingroup$ @AliceD, It's only trivial if you have a certain amount of experience. With vitamins and "nutraceuticals", I've seen errors caused by conflating and mislabeling between "mg", "mcg", and "Mg" (where "Mg" was perversely meant to be convey micrograms!) . This is so serious that the FDA has repeatedly warned about it $\endgroup$ – Brock Adams Aug 25 '15 at 7:52

$\begingroup$ @BrockAdams - you may be right, but then again I doubt this is the right forum for these matters. $\endgroup$ – AliceD♦ Aug 25 '15 at 13:01

This is a typo. In the text he states:
... only 0.120 milligrams (120 micrograms) of MK-4 ...
So, he knows the correct conversion.
Then:
... 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 4.5 milligrams.
