Vitamin K2 MK-7 – 100 µg – Osavi

Vitamin K2 MK-7 is a highly active form of menaquinone that plays a recognised role in normal bone maintenance and physiological calcium balance. Osavi provides this nutrient in a convenient capsule format using naturally fermented trans-form MK-7 sourced from plant-based natto fermentation. The capsules are designed for easy daily intake and are suitable for vegetarians, offering a clean-label formula with minimal additives.

What Is Vitamin K2 MK-7?

Vitamin K2 exists in several forms known as menaquinones, identified by chain length (MK-4, MK-7, etc.). MK-7 is widely studied due to its longer activity time in the body and its naturally occurring trans configuration when derived from fermentation. The 100 µg capsule format from Osavi is made using controlled fermentation processes that produce a stable and bioactive nutrient. The capsule design ensures accurate dosing for individuals following a consistent supplementation plan.

Technical Features – Vitamin K2 MK-7 (100 µg, Osavi)

Natural Trans MK-7 from Fermentation

The MK-7 used in this formula is obtained through a natural fermentation process from natto-derived bacterial cultures. This ensures a high proportion of the trans form, considered the physiologically relevant configuration. Osavi maintains strict quality standards to ensure purity, identity, and batch-to-batch consistency.

100 µg Precisely Standardised Content

Each capsule delivers 100 micrograms of menaquinone-7. The standardisation helps support predictable daily intake, making it suitable for long-term supplementation routines. This precision aligns with Osavi’s clean-label formulation strategy.

Vegetarian Capsules with Minimal Additives

Osavi uses a plant-derived hydroxypropyl methylcellulose (HPMC) capsule shell. The internal formulation contains only the active nutrient blended with necessary capsule-supporting excipients, keeping the ingredient list simple and clean. The capsules contain no unnecessary binders, artificial colours, or preservatives.

Highly Stable Menaquinone Form

MK-7 is valued for its structural stability and extended presence in the bloodstream compared to certain other menaquinone types. This extended half-life allows for consistent once-daily usage without rapid fluctuations in nutrient levels.

Scientific Context – Menaquinones in Human Nutrition

Vitamin K is a fat-soluble nutrient family that includes phylloquinone (K1) and menaquinones (K2). MK-7 has attracted considerable interest in nutritional science due to its longer biological activity and its presence in fermented foods. Its relevance in supporting normal calcium utilisation is widely acknowledged, and scientific research continues to explore its biochemical behaviour across different tissues.

Investigative Research Areas

• Menaquinone transport and distribution in human physiology
• Comparative stability of MK-7 versus shorter-chain menaquinones
• Role of vitamin K-dependent proteins in calcium-binding pathways
• Interactions between menaquinones and dietary fat absorption
• Fermentation-based production of trans-form MK-7
• Bioavailability variations across different vitamin K2 formulas

Documented Usage Contexts

Vitamin K2 MK-7 supplements are frequently used as part of various nutritional regimens where controlled intake of fat-soluble vitamins is supported. Common usage contexts include:

• Daily supplementation for maintaining adequate vitamin K intake
• Combination with calcium or vitamin D supplements within nutrition plans
• Inclusion in vegetarian and plant-based supplement programmes
• Use in targeted routines focusing on bone maintenance and structural health
• Standardised micronutrient intake programmes monitored by nutrition professionals

FAQ – Vitamin K2 MK-7

Is this product suitable for vegans?

Yes. The capsules are made from plant-based cellulose and contain no animal-derived ingredients.

Should it be taken with food?

A meal containing healthy fats is ideal, as vitamin K2 is fat-soluble and is best absorbed with dietary lipids.

Is MK-7 different from MK-4?

Yes. MK-7 has a longer activity time in the body and is derived from fermentation, whereas MK-4 is shorter-chain and commonly found in animal foods.

Can this be combined with vitamin D?

Combination is common in nutritional planning, but individuals on medication or with specific conditions should seek professional guidance.

Does it contain allergens?

The formula is free from common allergens such as gluten, lactose, and soy. Always check the label for the most current allergen information.
