In summary, the conversation discusses the potential benefits of vitamin K supplements in reducing dietary considerations when taking warfarin. It also mentions the importance of not altering medication or supplement dosages without consulting a physician. It is noted that vitamin K has other important functions and can have serious long-term effects. The thread is then closed to prevent further discussion on the topic.

TL;DR Summary
Can vitamin K supplements reduce dietary considerations in stabilizing INR on warfarin?
Can vitamin K supplements reduce dietary considerations in stabilizing INR on warfarin? I understand a higher dose of warfarin would be required. But isn't vitamin K useful besides as a coagulant, and wouldn't dietary sources of K impact INR less with a 100-200 mcg daily base of vitamin K supplemented?

Unless directed by a physician DO NOT alter dosages of medications or supplements. Altering supplements dosage or new use (which the health provider is aware of already hopefully)may be okay, otherwise it can cloud patient issues when taken during a meds introduction. Do not do it unless you are working with your provider. Period.

Also, consider that there are different forms of dietary Vitamin K that has to be factored in. And. Vitamin K has other very important functions.

Warfarin works well. But it has serious considerations and some potentially nasty long term effects.

1. Can vitamin K supplements interfere with warfarin therapy?

Yes, vitamin K supplements can interfere with warfarin therapy. Warfarin works by blocking the activity of vitamin K, which is needed for blood clotting. Taking additional vitamin K can counteract the effects of warfarin and increase the risk of blood clots.

2. How do vitamin K supplements affect INR levels in warfarin therapy?

Vitamin K supplements can increase the amount of vitamin K in the body, which can lead to higher levels of clotting factors and a decrease in the effectiveness of warfarin. This can result in a higher INR level, which indicates a longer time for blood to clot.

3. Can vitamin K supplements help stabilize INR levels in warfarin therapy?

No, vitamin K supplements should not be used to stabilize INR levels in warfarin therapy. Warfarin dosages are carefully adjusted based on INR levels, and taking additional vitamin K can disrupt this delicate balance and make it more difficult to maintain a stable INR level.

4. Are there any benefits to taking vitamin K supplements while on warfarin therapy?

There are no proven benefits to taking vitamin K supplements while on warfarin therapy. In fact, it can be dangerous to take additional vitamin K while on warfarin as it can increase the risk of blood clots and interfere with the effectiveness of the medication.

5. Is it safe to stop taking vitamin K supplements while on warfarin therapy?

It is important to consult with a healthcare provider before making any changes to your medication regimen. Stopping vitamin K supplements while on warfarin therapy may be recommended by your doctor if your INR levels are consistently too high. However, it is important to do so under medical supervision to ensure that your INR levels remain stable and you do not experience any adverse effects.
