Thanks for sharing, @heavyphil .

Here's the story. It looks like it's a type of vitamin K (menadione) rather than D3. In a study it slowed prostate cancer progression in mice, but has not yet been tested on humans:

Fingers crossed that something usable develops out of this — the more treatment options for us, the better. In the meantime, vitamin K is most plentiful in leafy greens, which we should be eating anyway for general health, so there's no harm in having a big kale or spinach salad every day.

They’re talking about vitamin K3 specifically when they mention menadione. K1 and K2 don’t seem to be the 6same thing, but they are in pill form. Where as K3 only seems to appear in food or food products.

I do eat a huge salad every day at lunch with a lot of kale in it. Maybe that’s one reason my PSA has stayed at < .1 for 11 months now.

Good to have a link to the study.

Oooops - my bad!!! I was so excited by the news that I mixed up my K’s and D’s. I take Vitamin D with K3, but they say that this K3 is NOT the one I take but a special form of it.
Well, whatever the letter of the alphabet, I’m all for it!
