Hey Toss,

I take approx 2500 mgs of vitamin D3 a day with no impact to my INR that I can tell. The other ones I don't have experience with except that my multi vitamin contains C and E.

I think if you take a wacky amount of any of these you could see an impact. I've heard people say vitamin C changes their INR but I don't know if that's true. I don't binge on anything with vitamin C, so I can't say from personal experience.

The only one of the above that I've added is Vitamin D. It's had no impact on my INR.
Reconsider taking vitamin E supplements though - it does have an anticoagulant effect and along with warfarin could cause problems. There's scads of info online about vitamin E & warfarin to back this up.
It's also relatively easy to get through dietary sources - few people have vitamin E deficiencies in this country, so supplementation is really not needed and recent info suggests it could even be unhealthy...here's one good article on it from WebMD

If you take any supplements, make sure they're MANUFACTURED in the USA, and buy from a reliable source. Many are made in China and don't contain what you think they do....

I've always been a believer in vitamins and supplements and take them separately based on conditions I have other than PEs. The fun of getting older? Because of the PEs my Dr went through the list of what I take and he told me to stop taking Vitamin E, CoQ10, herbal supplements and green tea. I still take Fish Oil capsules but just one per day now. I also swear by B-100s , D3 and take Vitamin C too but jut 500 mg of that.

I also take calcium and magnesium but 2 hours apart since the pharmacist told me they are better absorbed that way. I added an iron supplement - Feosol- since I tend to become anemic off and on and hope it helps to fight fatigue too.

Good luck to all of us nutritionally!

Not that I'm a doctor or anything, but I drink 5-8 glasses of green tea per day with no effect. Green tea leaves have lots of vitamin K, but vitamin K is fat soluble, not water soluble. So when you steep your tea leaves none of the vitamin K gets absorbed in the water. Just don't eat the leaves or steep in milk. :)

I take a multi-vitamin with no problems either. I think the best thing to do is take supplements that have your recommended daily intake, rather than therapeutic doses.

Bishop9 that's interesting about the green tea - I've read the same thing, that the vit. K in a brewed cup is, like, nothing. Yet Green Tea is specifically mentioned as something to avoid when your on warfarin, like it's guaranteed to tank your INR or something.

I'm a fan of getting my nutrients through food sources anyway, unless there's a specific deficiency that needs correcting. What IS a therapeutic dose of a vitamin? Who the hell knows? But it's easy to overdose on a garlic supplements - not so easy to eat enough garlic to cause problems. You'd lose all your friends first.

I suddenly dropped my INR to 1.8 from my reg 2-3 range at a regular monthly checkup. I took an extra dose ( at th eclinics order) and the next week I was down to 1.3. We racked our brains as to what, if anything, I did differently during that 2 week time frame. I started taking 500 mg of Vitamin C- but that didn't show up in the drug book or any of that nurse's references. She asked the others in the clinic, and with them all searching, we found one pamphlet that said Vit C in high doses (not specified, but the RDI is 60 mg) would lower the INR. THe next week I was taking at least 2 doses of NSAIDs a day, so my next INR was 3.0 . I cut back as my tendinitis got better, and Tuesday of this week it is at 2.1 ... so, swinging all over the place after having been stable for at least a month, lol. But if I wasn't taking the Vit C right now, I'd be too high with the NSAIDs for the hand.
I take 2000 IU of Vit D per day, but have been on that consistently even before the PE, so no info on that.
