More on Vitamin K

[Guest guest]

Hi Everyone,

After reading 's reply about vitamin K, I'm even more convinced that K

may play a big role in both estrogen production and in controlling

hyperthyroidism.

One source says that most of our vitamin K is synthesized in the intestines

by bacteria. This means that use of antibiotics can greatly diminish the

supply. Dairy foods containing lactobacillus bacteria, such as yogurt and

kefir are supposed to be a great source of vitamin K. For this reason, I

think it's a good idea for everyone to eat a little yogurt each day. Also,

it's great for the nausea that many people are experiencing.

I hate to draw conclusions from one case, but in 's case it certainly

looks like vitamin K is involved in estrogen production, since her periods

stopped right after starting coudadin. I read in a book that people on

coumadin should not take supplemental vitamin K unless approved by a

physician. What this indicates to me is that coumadin is effective as a blood

thinner BECAUSE it destroys vitamin K. Taking K would defeat the

effectiveness of coumaden. The fact that had such a bad reaction to

taking boron, which seems to work with K, lends further support that vitamin K

and boron work together to help produce estrogen.

Other drugs besides coumadin can cause vitamin K destruction: cholestyramine

(lowers cholesterol), the anticonvulsants Dilantin and phenobarbitol,

cephalosporin antibiotics, and mineral oil.

Maintaining a good supply of vitamin K is important in estrogen production,

which in turn is important in preventing osteoporosis. One sign of low K is

easy bruising and black-and-blue marks on the skin. (These can also have

other causes.)

Vitamin K is usually not in any multiple vitamin supplements, so be sure to

have a little yogurt or kefir each day.
