Many articles I sent to you in the past about vitamin K [via Yahoo group which was deleted by Yahoo]

I forward you now an e-book from Life Extension about vitamin K [have not read it myself yet] but in general Life Extension is a trustable site even if it is not free from commercials.

By the way: because of an article in Life Extension in the past about swine flu and glutathione I started looking for one of the richest sources of glutathione in nature and discovered from the huge website of James Duke z”l the herb Portulaca oleracea and started using this for flu many years ago.
