I just read some information on it but never heard of it until I watched a video on social media talking about it and saying it's not something the doctors tell women of color about but it's beneficial in our health

How does vitamin K2 work with heart disease, and is it safe to use?

Vitamin K2 is a nutrient found in foods like egg yolks, certain cheeses, and fermented foods. Research suggests it may offer some heart benefits, though studies are still in early stages.

Potential benefits for heart health:

* May help prevent calcium buildup in artery walls, which can lead to hardening and increased cardiovascular risk
* Some studies suggest people with higher vitamin K2 intake have fewer heart-related problems
* Supports bone strength by helping calcium stick to bones rather than arteries

Important safety considerations:

If you're taking blood thinners (especially warfarin), vitamin K2 can interfere with how your medication works. Warfarin blocks vitamin K to prevent clotting, so adding K2 can make the medication less effective and increase your risk of dangerous clots.

If you're on warfarin:

* Talk to your doctor before adding any vitamin K2 supplement
* Keep your vitamin K intake consistent from week to week
* You may need more frequent blood tests (INR checks) if you make changes
* Your medication dose might need adjustment

If you're on newer blood thinners (like Eliquis or Xarelto):

These are less affected by vitamin K2, but it's still wise to discuss with your healthcare provider before starting any supplement.

The key is balance and medical guidance. You don't need to avoid vitamin K2 completely, but changes should be made carefully with your doctor's input to protect both your heart and medication effectiveness.

Hi Gwen3, I was taking D3/K2 for years ever since I went to an acupuncturist. While there he recommended the D3/K2. My cardiologist did not take me off of it. As a matter of fact he approved every supplement I was already taking. It's interesting how different the doctors can me.

Hi Lucinda, I just noticed your post on Vitamin K2. I have not been told anything about K2. My doctor actually told me I should not take things over the counter since we have no idea what's in some of that stuff. He said some things were tested and apparently other ingredients were included but, not on the label. My Cardiologist told me to check with my PCP. As stated in the article, I do check with my doctors before taking anything new. I'll read up on K2. Thanks for being informative.
