Vitamin K2¶
Key Purpose¶
The Vitamin K2/MenaQ7 Axis: This is the cornerstone of the structural side. While many focus on blood flow, MenaQ7 activates Matrix Gla Protein, which physically prevents calcium from depositing in the arterial walls.
Dosage and Frequency¶
-
Currently 180 microgram per day
-
In the future, here are the values for clinical-grade cardiovascular support:
| Standard Dosage (General Health) | Clinical Dosage (Heart Health) | "2026 Updated ""Optimal"" Dose" |
|---|---|---|
| 90 mcg / day | 180 mcg / day | 320 mcg to 360 mcg / day |
Why the 2026 Recommendation Increased¶
-
The shift toward 320–360 mcg (often delivered as two 180 mcg doses) is based on newer longitudinal data regarding "arterial stiffness."
-
Vascular Elasticity: 2026 protocols suggest that while 180 mcg is enough to activate Matrix Gla Protein (MGP) to stop new calcification, the higher 360 mcg dose is more effective at supporting the body’s ability to maintain existing arterial flexibility.
-
Half-Life Optimization: Because MK-7 has a long half-life (about 72 hours), the higher 2026 dose ensures that "saturation levels" remain constant in the bloodstream, even if a day is missed.

Vitamin K2 Interaction with Protocol¶
There is no known negative interaction between iodine and Vitamin K2 (MenaQ7). In fact, they are synergistic for longevity:
- K2 manages calcium distribution (keeping it out of arteries).
- Iodine supports the metabolic rate and antioxidant status required for healthy vascular signaling.
Structural Protocol Considerations¶
Cardiovascular Synergy¶
Iodine supports the production of T3, which is a major regulator of systemic vascular resistance.
- Benefit: Proper iodine levels help maintain the elasticity of the vascular system, which aligns with your goals for cardiovascular support.
- Precaution: If you are taking any medication for blood pressure alongside your herbal teas (like Hawthorn, which has mild ACE-inhibitory effects), introducing high doses of iodine should be done gradually to ensure your heart rate remains stable.
Potency Rule for MenaQ7¶
For MenaQ7 to be effective, it must be fat-soluble.
Action: Do not take your MenaQ7 with your morning Hibiscus tea on an empty stomach. It is best taken with your a meal containing healthy fats to ensure that the MK-7 actually reaches your arterial tissues.
Brand Recommendations¶
| Brand | Product Name | Key Features | Dosage Strategy |
|---|---|---|---|
| Doctor's Best | Natural Vitamin K2 MK-7 with MenaQ7 | Most widely available; often bundled with Vitamin D3 (1,000 IU). | Take 2 caps daily (1 morning / 1 evening) to hit 360 mcg. |
| Ortho Molecular | Vitamin K2 180 mcg | Clinically focused; uses MenaQ7 PRO (higher purity standard). Often sold via physicians. | Take 2 caps daily. Highly stable formulation. |
| Carlson Labs | Vitamin K2 as MK-7 (180 mcg) | Trusted legacy brand; 100% MenaQ7 source. No added D3 (good if you take D3 separately). | Take 2 caps daily. Softgel or veggie cap options. |
| RetzlerRx | Vitamin K2 180 mcg (MenaQ7 PRO) | Physician-formulated for longevity and vascular health. Focuses on the "MK-7 saturation" protocol. | Take 2 caps daily. Minimal fillers. |
| HormoneSynergy | Vitamin K2 180 mcg | Uses the specific MenaQ7 PRO version tested for arterial elasticity. | Take 2 caps daily. High stability in warm climates. |
Buying Guide¶
The "PRO" Distinction: Brands like Ortho Molecular and RetzlerRx often use MenaQ7 PRO. This is the highest-grade version of the patent, specifically processed to be more stable when combined with minerals like Magnesium or Calcium in the stomach.
MCT Oil Carrier: If possible, look for the Carlson Labs softgels or liquid versions. Since Vitamin K2 is fat-soluble, being suspended in MCT oil can slightly improve initial absorption if you aren't taking it with a heavy meal.
Check for the Logo: In 2026, many brands use "generic" MK-7 to save costs. Always verify the MenaQ7 logo is on the physical label to ensure you're getting the chickpea-fermented, soy-free version that matches your clinical goals.
Important Storage Needs¶
- Newer stability testing for MenaQ7 in 2026 confirms that it is remarkably stable at room temperature, but sensitive to humidity.
Action
Keep your MenaQ7 bottle in a cool, dry cabinet—avoid the bathroom or kitchen counter near the stove—to prevent the capsules from clumping and degrading.
