Vitamin K

Vitamin K intolerance may stem from synthetic formulations, digestive issues, or medication interactions. Choosing natural sources, managing intake, and maintaining gut health can help optimize vitamin K levels while avoiding adverse effects.

🥬 What is Vitamin K?
Vitamin K is a fat-soluble vitamin essential for blood clotting, bone health, and cardiovascular function. It comes in two main forms: K1 (phylloquinone) found in leafy greens and K2 (menaquinone) found in fermented foods and animal products. While crucial for overall health, some individuals may experience intolerance or adverse reactions, especially from supplements or excessive intake.

🤔 Why Do I Have an Intolerance to Vitamin K?
Vitamin K intolerance can result from absorption issues, medication interactions, or sensitivity to synthetic forms.
• Fat malabsorption – Conditions like celiac disease or liver disorders can affect vitamin K absorption.
• Medication interactions – Blood thinners (e.g., warfarin) can be affected by vitamin K intake, leading to dosage inconsistencies.
• Synthetic vs. natural forms – Some individuals react poorly to synthetic vitamin K (e.g., K3, menadione).
• Digestive discomfort – High doses may cause nausea, bloating, or other gastrointestinal symptoms.

🛠️ What Can I Do About It?
❌ Avoid synthetic vitamin K – Stick to natural food sources like leafy greens and fermented foods.
🥑 Consume with healthy fats – Since vitamin K is fat-soluble, pairing it with healthy fats enhances absorption.
🔍 Monitor intake – Be mindful of vitamin K levels, especially if taking blood-thinning medications.
🥦 Diversify sources – Include both K1 (leafy greens) and K2 (fermented foods, dairy) for optimal benefits.
👩‍⚕️ Consult a healthcare provider – If experiencing symptoms, seek medical advice for testing and adjustments.

💊 Which Supplements Can Help with Chemical Sensitivities?
• Vitamin D – Works with vitamin K to support bone and heart health.
• Calcium & magnesium – Support bone structure and reduce imbalances from vitamin K fluctuations.
• Probiotics – Aid gut bacteria in producing vitamin K2 naturally.
• Omega-3 fatty acids – Enhance fat-soluble vitamin absorption.
• Nattokinase – A natural enzyme that supports healthy blood circulation and balances vitamin K effects.

🌟 Why Might I React to Vitamin K but Not Other Fat-Soluble Vitamins?
• Medication interactions – Vitamin K uniquely affects blood clotting, unlike vitamins A, D, and E.
• Gut microbiome role – The body relies on gut bacteria to synthesize vitamin K2, making gut health a factor.
• Synthetic forms – Unlike vitamins A and D, synthetic vitamin K3 can be more reactive in the body.
• Absorption differences – Certain conditions may impair vitamin K uptake while leaving other fat-soluble vitamins unaffected.

🍽️ Common Exposure Sources
• Leafy greens (kale, spinach, Swiss chard)
• Fermented foods (natto, sauerkraut, cheese)
• Broccoli and Brussels sprouts
• Egg yolks
• Liver and organ meats
• Vitamin K supplements (K1, K2, or synthetic forms)

🍽️ Alternatives (if tolerated)
• Natural vitamin K sources – Prioritize leafy greens, fermented foods, and eggs.
• K2-rich foods – Choose natto, hard cheeses, or pastured animal products for better absorption.
• Menaquinone supplements (K2) – A more bioavailable and well-tolerated form compared to synthetic K1.
• Gut health support – Consume probiotic-rich foods to aid natural vitamin K2 production.
