MK-7 Plus with K1 & MK-4 - 90 Veg Capsules

How It Works in the Body

Think of calcium in your circulation like unguided cargo ships on a crowded waterway. Without trained harbor pilots to steer them into unloading docks, ships can drift into narrow canals and block traffic. Vitamin K acts as that team of harbor pilots, docking calcium securely inside skeletal bone docks while keeping circulatory shipping lanes open and clear [4].

The Molecular Relay: Gamma-Glutamyl Carboxylation

At the cellular level, all forms of Vitamin K serve as mandatory cofactors for an internal enzyme called gamma-glutamyl carboxylase [1]. This enzyme attaches a carbon dioxide molecule to glutamic acid residues on specific target proteins, transforming them from an inactive state into an active, calcium-binding state [1, 4]:

• ✓ Osteocalcin Activation: In bone tissue, carboxylation turns osteocalcin into a biological magnet that locks calcium ions (Ca²⁺) directly into the skeletal hydroxyapatite crystal lattice [3, 4].
• ✓ Matrix Gla Protein (MGP) Activation: In cardiovascular tissue, carboxylation activates MGP, forming a molecular shield along vascular walls that prevents calcium deposits from stiffening blood vessels [1, 4].

Tri-Phase Pharmacokinetics: Short, Intermediate & Long-Chain Action

Each form in this formula supports distinct biological compartments. Vitamin K-1 (chemical formula C₃₁H₄₆O₂) is absorbed via triglyceride-rich lipoproteins and taken up rapidly by the liver to support hepatic clotting factor synthesis [1]. Menaquinone-4 (MK-4, chemical formula C₃₁H₄₀O₂) provides specialized localized activity across non-hepatic peripheral tissues [2]. Finally, MenaQ7® Menaquinone-7 (MK-7, chemical formula C₄₆H₆₄O₂) incorporates into low-density lipoproteins (LDL), circulating throughout your systemic vascular network for more than three days to ensure sustained carboxylation of bone and arterial proteins [1, 3].

Daily Timing, Synergy & Realistic Timelines

Best Time to Take & Daily Schedule

Take 1 veg capsule daily with a meal. All forms of Vitamin K are fat-soluble nutrients that depend on dietary fats for proper micelle formation and intestinal uptake. Pair your capsule with foods containing healthy fats such as eggs, avocado, olive oil, or yogurt. Morning or midday intake alongside breakfast or lunch is ideal for consistent daily absorption.

Smart Pairings & Spacing Rules

• ✓ Vitamin D-3 Synergy: Pair with Vitamin D-3. Vitamin D stimulates the physical production of osteocalcin and MGP, while Vitamin K chemically activates them [4].
• ✗ 2-Hour Fat-Binder Spacing: Separate this capsule by at least two hours from fat-blocking compounds, bile acid sequestrants (such as cholestyramine), or large amounts of soluble psyllium fiber to avoid impaired absorption.

What to Expect Over Time

• ✓ Days 1–7: Rapid uptake of K-1 and MK-4 supports immediate cellular replenishment, while long-chain MK-7 begins building stable circulating plasma levels [1, 2].
• ✓ Weeks 3–4: Sustained blood concentrations of MK-7 continuously drive the carboxylation of osteocalcin in bones and MGP in vascular walls [1, 3].
• ✓ Months 2–3+: Long-term tissue saturation provides cumulative support for structural bone density retention and healthy cardiovascular flexibility [3, 4].

Physical Feel, Sensory Traits & Clean Ingredients

Pill Format & Ease of Use

Supplied in a compact, two-piece Size #1 vegetarian capsule. The plant-based hypromellose shell becomes slick when moistened with water, sliding down smoothly without throat friction. If you experience difficulty swallowing pills, you can gently pull the two capsule halves apart and stir the neutral powder directly into yogurt, applesauce, or a spoonful of culinary olive oil. Never mix into steaming liquids, as intense heat can damage sensitive fat-soluble vitamin bonds.

Natural Aroma, Taste & Color

These vegetable capsules are completely neutral in flavor with a faint, clean botanical aroma. The encapsulated powder displays an off-white to pale cream color. Natural color variation may occur from batch to batch, which is a normal characteristic of authentic, fermentation-derived ingredients free from artificial colorings.

Other Ingredients Explained

• ✓ Microcrystalline Cellulose & Mannitol: Purified plant-derived fibers that serve as inert, non-allergenic carriers to guarantee precise microgram dosing across every capsule.
• ✓ Maltodextrin: A food-grade carbohydrate matrix used to protect and evenly disperse delicate fat-soluble vitamins throughout the blending process.
• ✓ Hypromellose (cellulose capsule): A 100% vegetarian capsule shell crafted from pine wood pulp that dissolves swiftly in gastric fluid.
• ✓ Ascorbyl Palmitate: A fat-soluble form of Vitamin C acting as an organic antioxidant shield to protect active menaquinones from oxidation.
• ✓ Silicon Dioxide: A naturally occurring mineral compound (silica) that prevents clumping and maintains uniform encapsulation density.

Proper Storage

Store in a cool, dry place after opening, away from high heat, excessive moisture, and direct sunlight. Keep the bottle tightly closed between uses. This container is manufactured from 100% post-consumer recycled (PCR) resin, protecting your supplements while reducing plastic waste.

Manufacturer Quality & Lab Testing Standards

Many mass-market and big-box store supplement brands rely on low-bid contract packers that omit rigorous raw material testing, leaving finished products susceptible to heavy metal impurities and sub-potent degradation. NOW Foods avoids these risks by operating comprehensive in-house analytical laboratories accredited under ISO/IEC 17025—the worldwide gold standard for testing and calibration competence. Their analytical team performs tens of thousands of tests each month across state-of-the-art platforms:

• ✓ ICP-MS Heavy Metal Testing: Inductively Coupled Plasma Mass Spectrometry inspects raw materials and finished lots for lead, arsenic, cadmium, and mercury down to parts-per-billion (ppb) thresholds, surpassing strict California Proposition 65 guidelines.
• ✓ HPLC Potency Verification: High-Performance Liquid Chromatography rigorously confirms that every capsule delivers the precise labeled amounts of 120 mcg K-1, 360 mcg MK-4, and 90 mcg MenaQ7® MK-7 through its expiration date.
• ✓ Solvent & Contaminant Screening: Tandem chromatography systems verify the complete absence of harmful chemical residues, synthetic processing aids, and industrial adulterants.
• ✓ Microbiological Pathogen Clearance: Automated assays confirm zero contamination from biological pathogens, including Salmonella species, Escherichia coli, and mold.
