Oral Vitamin K Safer than Injected
Clinical Study Title:
Oral versus intramuscular phytomenadione: safety and efficacy compared.
[

English Summary: |
This
study looked at the safety of vitamin K administration.
Recent studies have indicated that vitamin K could
be carcinogenic when given in injections. There are
advantages to the use of an injection form of vitamin
K over the oral supplement, but there may be adverse effects. Oral supplementation of
vitamin K given over a long time can be as effective
as the injection form. Various other studies were
reviewed to look for evidence of an increased risk
of cancer with an injection of vitamin K, but almost
all studies did not support this theory. Vitamin K
is considered safe and effective, and this can be
said of both oral and intramuscular administrations.
