At Flush, we emphasise the nutrients that quietly power your body’s repair and resilience. Vitamin K is one such micronutrient—rarely talked about, but essential. It supports efficient blood clotting, wound healing, cardiovascular balance, and bone strength, making it a vital piece of your detox and longevity toolkit.

Vitamin K1 vs Vitamin K2

There are two main forms of vitamin K:

• Vitamin K1 (phylloquinone) – found in leafy greens and most plant foods. This form ensures normal blood clotting and vessel integrity.

• Vitamin K2 (menaquinones) – found in fermented foods (like natto) and certain animal products. K2 goes further, supporting bone health, reducing inflammation, and even protecting cardiovascular function by helping calcium go where it belongs—into bones, not arteries.

While deficiency in adults is rare, low K2 intake is surprisingly common in Western diets. This is why Flush highlights vitamin K2—not as a “bonus nutrient,” but as a critical cofactor for detox, repair, and long-term resilience.

The Role of Vitamin K in Bone & Cardiovascular Health

• Stronger bones: Vitamin K2 activates osteocalcin, a protein that locks calcium into bone tissue. Without it, calcium can linger in the blood and fail to strengthen your skeleton.

• Heart protection: By activating matrix Gla protein, vitamin K2 helps keep calcium out of arteries—reducing calcification and protecting vessel elasticity. This is why higher K2 intake is linked to lower risk of cardiovascular disease.

• Synergy with Vitamin D: Flush emphasises how vitamins work together. Vitamin D boosts calcium absorption, but vitamin K2 directs calcium to the right place. Without K2, extra calcium can actually do more harm than good.

Flush Perspective

From a detox and cellular renewal standpoint, vitamin K is about flow and direction. It keeps blood vessels elastic, bones strong, and ensures minerals are channelled into tissues where they’re most needed. That’s why we consider vitamin K2 a quiet but powerful ally in any Flush protocol.

While K1 is easily obtained from greens like spinach, kale, and broccoli, K2 requires more intention—coming mainly from fermented foods or targeted supplementation. For most people, topping up with K2 can make all the difference in sustaining repair and avoiding hidden imbalances.

Key Sources of Vitamin K

• K1 (phylloquinone): kale, spinach, broccoli, Brussels sprouts, cabbage

• K2 (menaquinones, especially MK-7): natto, aged cheeses, fermented foods, egg yolks, liver

Supplements often use MK-7, as it is stable and highly bioavailable.

Flush takeaway: Vitamin K isn’t just about clotting—it’s about balance. With the right intake of K1 and K2, your body can heal, detox, and protect itself with far greater efficiency.
