Food or Supplement Vitamin K Absorption
Clinical Study Title:
Comparison of phylloquinone bioavailability from food sources or
a supplement in human subjects.
| Plain
English Summary: |
The
absorption of vitamin K from a standard meal was examined
in young adults. The absorption from the meal was
compared to the vitamin K absorption after a supplement
was given. There was a difference in vitamin K absorption
from different fruits and vegetables. It was found
that larger quantities of spinach were able to be
digested for a higher absorption of vitamin K. Most
of the green vegetables were able to provide some
source of vitamin K. However, a supplement of vitamin
K was also easily absorbed and was able to provide
more vitamin K. |
