Vitamin K Deficiency? 3 Warning Signs You Can’t Ignore & How to Fix It
Among all dietary supplements and vitamins, vitamin K is a silent supporter of essential body functions. Surprisingly, this vitamin is not discussed as frequently as others. Beyond its role in blood clotting, it also benefits bones, heart health, and skin! In this guide, we explore the wonders of vitamin K, its natural sources, and practical tips to incorporate it into your daily routine.
Types of Vitamin K: What’s the Difference?
Vitamin K has three primary classifications, each with distinct roles:
1 . Vitamin K1 (Phylloquinone)
- Sources: Leafy green vegetables like broccoli, spinach, and kale.
- Key Insight: K1 has a low absorption rate (around 10%), However, pairing it with healthy fats like olive oil can enhance absorption.
2 . Vitamin K2 (Menaquinone)
- Sources: Animal liver, organic egg yolks, and fermented foods like natto.
- Hidden Benefit: Notably, the MK-7 subtype (45mg) is linked to combating osteoporosis.
3 . Vitamin K3 (Menadione)
- Caution: A synthetic form with potential side effects, Therefore, avoid unless prescribed by a healthcare provider.
Beyond Blood Clotting: The Multifaceted Benefits of Vitamin K
1. Bone Health: Preventing Osteoporosis & Fractures
- How It Works: Primarily, it activates osteocalcin, a protein that binds calcium to bones.
- Research Insight: For example, women with higher K2 intake experience 60% fewer hip fractures.
- Tip: To maximize benefits, pair K2 with vitamin D3 for optimal calcium absorption.
2. Heart Health: Fighting Arterial Calcification
- Mechanism: Specifically, it activates matrix Gla protein (MGP), which prevents calcium buildup in arteries.
- Critical Fact: Studies indicate that low K2 levels may increase heart disease risk by 57%.
3. Skin and Cognitive Benefits
- Skin Health: Additionally, it prevents elastin calcification, maintaining skin elasticity.
- Emerging Research: Early findings suggest a potential role in reducing Alzheimer’s risk.

Supplements: Types, Dosage, and Risks
- K1 Supplements: Typically, used for blood clotting support (100–200 mcg, 3x weekly).
- K2 Supplements:
- MK-4: In clinical settings, high doses (e.g., 45mg) for osteoporosis under medical supervision.
- MK-7: Generally, 100–200 mcg daily for general health.
- Risks of Overdose:
- Crucially, may interfere with blood thinners like warfarin.
- Excessive doses (>500mg), can cause dizziness or clotting issues.
Vitamin K Deficiency: Signs and Solutions
- Symptoms: Commonly, frequent bleeding gums, unexplained bruising, bone/joint pain.
- High-Risk Groups: Infants, for instance, require K1 shots; similarly, Crohn’s patients or those on warfarin.
- Treatment: To address this, increase dietary K1/K2 intake or use MK-7 supplements (100–200 mcg/day) after consulting a doctor.
Synergy with Other Nutrients
- Power Pair: K2 + Vitamin D3
- Together, they enhance calcium absorption and direct it to bones.
- Recommended Dose: Ideally, 1000–2000 IU D3 + 100 mcg K2 daily.
- Critical Caution: Always avoid combining K supplements with blood thinners without medical advice.
5 Simple Ways to Boost Vitamin K Intake
- Power Salad: Start by combining spinach, avocado and olive oil.
- Fermented Foods: Next, add sauerkraut or natto to meals.
- Pasture-Raised Eggs: Alternatively, choose organic for triple the K2 content.
- Swap Margarine for Butter: For a healthier option, opt for K2-rich grass-fed butter.
- Balance Fats: Finally, pair K-rich foods with healthy fats for better absorption.
FAQ: Common Questions Answered
- Are Supplements Safe?
Yes, but note that doses above 45mg require medical supervision. - Can Vegans Get Enough K2?
