True or false: Your body can manufacture both Vitamin D and Vitamin K.
[See the full post at: Daily Quiz for March 18, 2020]
I answered correctly. What is uncertain is if the body can produce enough of these vitamins, or so says the person whose doctor makes her take 2000 IU of Vitamin D per day, although that may be to go with the 1200mg calcium, only 300 of which I take in a pill form, preferring to get the rest in diet. The rationale is that 1) older people (when did I get "old?) do not produce Vitamin D as efficiently, and 2)people who live in more northern climates, particularly in the winter, do not get enough of the minimal sun exposure necessary to produce an adequate amount
I write the above, fully aware that a LOT of sources are now saying that there is no advantage to large doses of Vitamin D. Sigh.
