Introduction to Arterial Calcification00:00:00
Arterial plaque buildup is often silent and dangerous. Recent studies suggest Vitamin K2 may slow arterial calcium buildup by nearly a third, but understanding the nuances of how and why is critical.
Understanding Vitamin K2 (MK4 and MK7)00:01:42
Vitamin K2 is a fat-soluble vitamin involved in calcium management. While MK4 and MK7 are both beneficial, MK7 is the focus of most recent studies due to its longer half-life in the bloodstream.
Analyzing the VitaK2 CAC Study00:03:32
A study using 360mcg of K2 daily showed a 30% reduction in calcium score progression compared to a placebo. However, it is noted that this only slows the score and does not reverse existing disease or necessarily guarantee a reduction in heart attack risk.
The Two Types of Calcification00:05:49
Not all calcification is the same. Small, patchy calcium indicates unstable, inflamed plaque, while dense, solid calcium often represents healed, stable tissue. More calcium can sometimes be a sign of successful healing rather than increased danger.
The Importance of Lifestyle and Metabolic Health00:07:15
Lifestyle factors like diet, exercise, and stress management are the primary drivers of health. K2 functions best as an add-on to support metabolic health and insulin sensitivity rather than as a standalone solution.
Practical Advice and Recommendations00:11:19
For those looking to heal their arteries, a dosage of 300-400mcg of K2 is recommended as part of a broader health strategy. It is essential to recognize that calcium scores may rise during the healing process as soft plaque stabilizes.
Diagnostic Tools Beyond Calcium Scores00:13:18
Because calcium scans do not show soft plaque, other diagnostic tools like CIMT and AI-read CT angiograms provide a more comprehensive view of arterial health to determine true risk.
