Vitamin K

Optimal Result: 130 - 1500 pg/mL.

Understanding Vitamin K Biomarkers (pg/mL)

Vitamin K is a fat-soluble vitamin crucial for blood clotting, bone health, and cardiovascular function. Assessing Vitamin K status is complex, as there is no single gold-standard biomarker. Several biomarkers are used to evaluate Vitamin K levels, each with its own strengths and limitations.

Key Biomarkers

  • Serum Vitamin K1 (Phylloquinone):
    • Normal range: 0.2 to 1.0 ng/mL in healthy individuals.
    • Reflects recent dietary intake (50 to 150 mcg/day).
  • Undercarboxylated Osteocalcin (ucOC):
    • Measured in ng/mL.
    • Elevated levels indicate Vitamin K deficiency.
    • More stable and reflective of tissue Vitamin K status than serum levels.
  • PIVKA-II (Protein Induced by Vitamin K Absence):
    • Used in conjunction with other markers.
    • Elevated in Vitamin K deficiency.

Clinical Implications

Low Vitamin K status can lead to:

  • Impaired blood clotting, increasing the risk of excessive bleeding.
  • Reduced bone density, heightening the likelihood of fractures.
  • Potential cardiovascular complications, as Vitamin K plays a role in preventing arterial calcification.

High levels of Vitamin K are rare but may result from supplementation or underlying health conditions.

Who Should Be Tested?

Testing for Vitamin K levels is particularly valuable for individuals at risk of deficiency, such as:

  • Patients on anticoagulant medications (e.g., warfarin).
  • Individuals with malabsorption conditions like celiac or Crohn’s disease.
  • Those with limited dietary intake of Vitamin K-rich foods (such as leafy greens, broccoli, and fermented foods).
  • Patients experiencing unexplained bleeding disorders or osteoporosis.

Interpretation and Considerations

  • Serum Vitamin K1 levels can be influenced by recent dietary intake and may not accurately reflect tissue status.
  • Undercarboxylated osteocalcin is a more stable biomarker that reflects longer-term Vitamin K status.
  • Multiple biomarkers may be necessary for a comprehensive assessment.
  • Factors such as age, liver disease etiology, and tumor invasiveness can affect biomarker performance.

Maintaining optimal Vitamin K levels supports critical biological processes. If your results are outside the normal range, it is advisable to consult a healthcare provider for tailored guidance and potential interventions. This version enhances clarity and provides a more comprehensive understanding of Vitamin K biomarkers.

What does it mean if your Vitamin K result is too high?

Several vitamins can be dangerous when you take too much of them, but for most people, vitamin K isn't one of them. The only people who could get too much vitamin K are those taking the blood-thinning medication warfarin.

If you decide you want to increase or decrease your vitamin K intake, it's important to discuss with your doctor the best way to do that, as your dosage may need adjusting either up or down.

If you're taking warfarin, you likely get regular blood tests to determine its efficacy. Your lab results will provide your prothrombin time (PT) and international normalized ratio (INR) values. Your INR values should stay in a safe range; if they are too high or too low, it may be because of the interaction between warfarin and vitamin K.

Vitamin K functions to lower your INR values, which means that warfarin may not be effective for preventing a blood clot. Warfarin increases your INR values, which slows blood clotting. If warfarin is too effective, you will bleed more easily and quickly, which can be dangerous.

If you are still determining whether Healthmatters support your lab results, the rule is that if you can test it, you can upload it to Healthmatters.

While we work with many popular labs, we welcome reports from lots of other places too.

It's as simple as this: if you can get a test done, you can upload it to Healthmatters and we can interpret results from any lab out there. If laboratories can analyze it, we can interpret it.

If you’re on the hunt for a specific biomarker, contact us and we'll add it to our database. Anything from blood, urine, saliva, or stool can be uploaded, understood, and tracked with your Healthmatters account.

There are two ways to add your test reports to your Healthmatters account. One option is to input the data using the data entry forms. The other method is to utilize our "Data entry service."

Our data entry forms offer an easy, fast, and free way for you to input the reports yourself. Self-entry allows you to add an unlimited number of reports at no cost. We make the self-entry process user-friendly, providing dozens of templates that pre-populate the most popular laboratory panels and offering instant feedback on entered values.

For those who prefer assistance, we offer a "Data entry service" to help you input your data. Simply attach an image or file of your lab test results, and a qualified team member from our data entry team will add the results for you.

We support various file types, including PDFs, JPGs, or Excel. This service is particularly useful if you have many reports to upload or if you're too busy to handle the data entry yourself.
