Exploring Vitamin K2 and D3 for Heart Health: Insights and Strategies

A user shares their journey of managing heart health post-triple bypass surgery, exploring the role of Vitamin K2 and D3 in calcium metabolism and vascular health. The assistant offers insights on supplements, calcium levels, and monitoring strategies to guide informed health decisions.

  • Quick story: had a triple bypass last year at 45. No heart attack, caught it before anything bad happened. None of my docs know why. One says cholesterol (total has been around 220 all my life), one says genetics, one says long covid symptoms. I can't fix something if I don't know the cause so that's the reason I'm here...

    I've been going down the rabbit hole of "what could be happening here" and I've settled on an area I want to pursue further: calcium in the blood causing build up and eventual blockages. The Norwegian study is what put me on to it as a possibility for my problems.

    Since reading the study I have started a 90 day regiment of 200mcg of VitK2 MK7 and now I am over to 100mcg a day. Eventually I'll be flying to Turkey to get a cheap angiogram to see if the disease is progressing or if I'm on the right track but right now I'm looking for more ideas.

    One thing I want to throw in to the mix is I have been supplementing with VitD3 (10,000 iu /day, five days a week, I skip weekends). This has put my VitD levels right in mid line (65). However, I am starting to find information on VitD increasing calcium in the blood.

    Side note: I have never had a calcium test that showed me being "high" but I've always been in the higher range of the scale.

    I guess I'm here to see if anyone in this sub can either point me in a new direction, give me their anecdotal evidence of what they have gone through/how they fixed it and/or tell me I'm on the right/wrong path. Any ideas are welcome.

  • I'm glad to hear that you're being proactive about your health and looking for ways to manage your condition. Since you're interested in the role of calcium and Vitamin K2 and D3 in cardiovascular health, I'll provide some insights on these supplements and their potential relationship with vascular calcification.

    Vitamin D3 and Calcium

    Vitamin D3 (cholecalciferol) plays a crucial role in calcium metabolism. It enhances the absorption of calcium from the gastrointestinal tract. While adequate vitamin D levels are essential for bone health, there is some evidence suggesting that excessively high levels of vitamin D could potentially contribute to increased calcium in the blood, which might play a role in vascular calcification1. However, since your vitamin D levels are in the middle range (65), this may be less of a concern, but it's always good to monitor it.

    Vitamin K2

    Vitamin K2 is known for its role in activating proteins that regulate where calcium ends up in the body. Specifically, it activates osteocalcin, which helps bind calcium to bone, and matrix Gla-protein (MGP) which helps prevent calcium from being deposited in the arteries2. The form you are using, MK-7, is a long-acting version and is often used for cardiovascular benefits. The Norwegian study you mentioned aligns with other research suggesting that vitamin K2 can help prevent arterial calcification and improve cardiovascular outcomes3.

    Calcium Levels

    Although your calcium tests have shown you're not "high," being on the higher end of normal can still have implications for circulatory health, especially if there are pre-existing cardiovascular conditions. It's essential to maintain a balance where calcium is adequately absorbed but not excessively circulating in the bloodstream without the proper guidance from proteins modulated by vitamin K2.

    Considerations

    • Calcium Scoring: Since you mentioned considering an angiogram, you might also want to look into a coronary artery calcium (CAC) scan. It's a non-invasive way to assess calcium deposits in your coronary arteries and can be a good indicator of your cardiovascular health.

    • Regular Monitoring: Continue to regularly monitor your vitamin D levels, and also discuss with your healthcare providers the possibility of monitoring vitamin K levels and the balance of your calcium

      ratio. Magnesium plays a supportive role in calcium metabolism.

    • Consultation with Specialists: If you haven't already, consider seeing a cardiologist specialized in metabolic or integrative medicine. They can provide a more tailored approach considering all aspects of your metabolism and cardiovascular health.

    It seems like you are approaching this from multiple angles, which is wise. Making informed decisions based on comprehensive health data is key to managing such complex health issues.
