Quick Summary:
- 97% of adults are deficient: Most people over 35 are low in vitamin K2 and don’t know it — and the health consequences are serious.
- It’s as dangerous as smoking: Research shows vitamin K2 deficiency increases the risk of early death at a rate comparable to smoking a pack of cigarettes daily.
- Calcium goes to the wrong place: Without vitamin K2, calcium from food and supplements ends up in your arteries instead of your bones — this is called the calcium paradox.
- Vitamin K2 activates two key proteins: MGP removes calcium from arteries, and osteocalcin locks it into bones where it belongs.
- Always pair D3 with K2: Taking high-dose vitamin D3 without K2 can actually worsen arterial calcification over time.
- Use MK-7, not MK-4: MK-7 has a longer half-life and better absorption — look for a microencapsulated capsule form that won’t go rancid.
- Perfect Vitamin D&K covers both: Dr. Sam uses and recommends Perfect Vitamin D&K — the right dose of D3 and K2 together in one plant-based, microencapsulated formula.
You already know that smoking kills.
But what if I told you there’s a common vitamin K2 deficiency that’s nearly as dangerous for your heart as smoking a full pack of cigarettes every day?
New research shows that being deficient in vitamin K2 increases your risk of early death almost as much as smoking. Other deficiencies affect your mood – see what vitamin or mineral deficiency causes anxiety.
Even worse, about 97% of adults over the age of 35 are deficient and have no idea. I was one of them until I discovered it through a detailed blood test more than a decade ago.
Today, you’ll learn how to reverse arterial calcification and move calcium out of your arteries and back into your bones, where it belongs.
Why Arteries Harden as You Age
Think of your arteries like a brand-new garden hose.
They’re flexible, strong, and allow blood to flow easily.
However, as you age, a process called vascular calcification occurs. Calcium builds up inside the arterial walls, causing them to stiffen and harden.
As a result, blood pressure rises. The risk of heart attacks and strokes skyrockets.
Many doctors will tell you this is just normal aging. They’re wrong. In fact, I’ve seen plaque buildup reversed in clients and family members.
The Calcium Paradox and Vitamin K2
Many people take calcium supplements for bone health.
Others get calcium from dairy or multivitamins.
Here’s the problem.
Without vitamin K2 directing calcium, it doesn’t go into your bones.
Instead, it ends up in your arteries and heart valves.
You think you’re strengthening your bones. But you’re actually hardening your arteries.
This is called the calcium paradox.
You don’t need more calcium. You need to tell calcium where to go. That is exactly what vitamin K2 does.
The Missing Vitamin That Protects Your Heart
That “traffic cop” nutrient is vitamin K2. Not vitamin K1. Vitamin K2 activates two critical proteins:
- MGP: Removes calcium from arteries and soft tissue
- Osteocalcin: Locks calcium into bones where it belongs
Without vitamin K2, arteries harden while bones weaken.
The Research Behind Vitamin K2
The evidence is clear.
In the Rotterdam Study, nearly 5,000 people were followed for over a decade.
Those with the highest vitamin K2 intake had a 57% lower risk of dying from heart disease.
Furthermore, another study found that the mortality risk of K2 deficiency was nearly identical to smoking cigarettes.
Correcting this deficiency can therefore be as powerful as quitting smoking.
Why You Must Take Vitamin K2 With D3
Vitamin D3 acts like a gatekeeper.
It increases calcium absorption into the bloodstream. Vitamin K2 acts like a guide.
It directs calcium into bones and away from arteries.
Moreover, taking high-dose vitamin D without vitamin K2 can increase arterial calcification over time.
That is why D3 and K2 must always be taken together.
Best Sources of Vitamin K2
Food sources are limited.
Fermented foods like natto contain K2, but most people don’t eat them.
Consequently, supplementation is the most reliable option.
If you supplement, use:
- Vitamin K2 as MK-7 — not K1
- Avoid MK-4 due to short half-life
- 50–100 mcg daily
Liquid or microencapsulated capsules absorb best and don’t go rancid.
Why Vitamin K2 Matters for Your Entire Body
Improving calcium metabolism improves circulation. That affects:
- Heart health
- Brain function
- Skin and eyes
- Muscle performance
- Sexual health
Vitamin D3 functions like a hormone. Vitamin K2 keeps calcium where it belongs. Together, they should be part of every adult’s daily health routine.
Final Thoughts on Vitamin K2
This isn’t about fear.
It’s about fixing a silent deficiency that affects nearly everyone.
So take Vitamin D3 with vitamin K2.
Protect your arteries. Strengthen your bones. And dramatically reduce your risk of heart disease.
Important "Increase Your Vitamin D+K" Shortcut
There are literally dozens of health benefits when improving your Vitamin D levels ... However, there are two big problems:
- Problem #1: About 93% of people are deficient or sub-optimal levels of Vitamin D
- Problem #2: Primary way to get Vit D is from 45-60 min of daily sunlight daily (your entire body, not just face or hands)
This is why its best to take a daily supplement to ensure you have healthy & optimal Vit D levels.
And make sure you take Vit D3 with K2 to ensure proper absorption and calcium metabolism for brain & heart health.
