Vitamin K2—especially MK-7—is one of the missing links I see over and over in people dealing with iron dysregulation + insulin resistance.
Here’s why it matters 👇
K2 helps direct calcium where it belongs (bones, teeth) and keeps it out of soft tissues (arteries, joints, organs). When K2 is low, calcium can accumulate in the wrong places—this is often seen alongside inflammation, poor metabolic health, and disrupted iron handling.
MK-7 (a form of K2) is especially powerful because it stays active in the body longer, helping regulate proteins involved in:
• Glucose metabolism
• Insulin sensitivity
• Vascular health
• Inflammation control
👉 In the context of iron dysregulation, this matters. Poor mineral balance (iron + calcium + magnesium) + chronic inflammation = metabolic dysfunction. K2 helps restore order.
BUT—supplements are not the foundation.
The goal is always food first, especially forms of K2 your body recognizes best:
✔️ MK-4 (animal-based)
✔️ MK-7 (fermented foods)
🥩 High MK-4 foods:
• Grass-fed butter
• Egg yolks
• Liver
• Full-fat dairy
🥢 High MK-7 foods:
• Natto (highest by far)
• Aged cheeses (gouda, brie)
• Fermented foods (sauerkraut, kefir—smaller amounts)
⚖️ K1 vs K2 (important distinction):
• K1 (phylloquinone) = found in leafy greens → mainly supports blood clotting
• K2 (menaquinone) = found in animal + fermented foods → regulates calcium, supports metabolism, heart, and bone health
Most people get plenty of K1… but are deeply lacking in K2.
⚠️ When might you need MK-7 supplementation?
If you’re dealing with:
• High ferritin / iron overload patterns
• Insulin resistance
• Chronic inflammation
• Poor dental or bone health
A short-term supplement can help stabilize things and get you out of a deficit…
But long-term health = consistent intake from real food.
This is about rebuilding mineral balance—not chasing symptoms.
Your metabolism depends on it. 🔥
