Description
What is Vitamin K2 MK-7 Crystal 98%?
Vitamin K2 MK-7 Crystal 98% refers to a high-purity (98%) crystalline form of menaquinone-7 (MK-7), a key subtype of Vitamin K2. Naturally derived via fermentation (typically from Bacillus subtilis natto),
its 98% crystal purity ensures minimal impurities and optimal bioactivity.
Unlike other Vitamin K2 variants, MK-7 boasts a long half-life in the body, supporting sustained effects. It primarily promotes bone mineralization by directing calcium to bones and teeth, while reducing vascular
calcification for cardiovascular health.

Food Industry:As a natural nutrient fortifier, it is widely added to functional foods (e.g., fortified milk, yogurt, health drinks, and nutritional bars) and dietary supplements. Targeting populations like the elderly,
osteoporosis-prone groups,adults needing cardiovascular support, it regulates calcium metabolism to enhance bone mineralization and reduce vascular calcification, with 98% high purity ensuring optimal efficacy.
Cosmetics Industry:as a natural active ingredient in cosmeceuticals (e.g., anti-aging creams, serums, and skin-nourishing products). Its antioxidant properties and ability to support collagen synthesis help improve
skin elasticity, mitigate age-related dullness, and protect skin from oxidative damage, aligning with the demand for "natural and effective" skincare ingredients.
Pharmaceutical Industry:as a key raw material for pharmaceutical formulations, primarily used in drugs for bone health (e.g., medications for osteoporosis, bone fracture repair, and osteoarthritis) and cardiovascular
health supplements. Compliant with pharmaceutical-grade purity standards, it ensures stable bioactivity and safety for clinical applications, supporting the treatment and prevention of age-related chronic diseases.
High Purity & Quality Consistency: 98% purity verified by HPLC, minimal impurities, stable batch-to-batch performance, compliant with USP/EP/FCC standards.
Natural & Safe Production: Advanced fermentation technology, no harmful solvents/residues, excellent bioactivity and biocompatibility.
Global Regulatory Compliance: Manufactured in GMP-certified facilities, backed by ISO quality management systems, meets food/cosmetic/pharmaceutical regulations worldwide.
Superior Stability & Compatibility: Crystalline form ensures strong stability, easy storage, and high compatibility with supplements, functional foods, and cosmeceutical formulations.
Flexible Supply Capacity: Scalable production lines, reliable inventory, supports small-batch trials and bulk orders, providing efficient supply chain solutions for global partners.
Q1:How does it differ from other Vitamin K2 (e.g., MK-4, MK-9)?
A1: Compared to MK-4 and MK-9, MK-7 has a longer half-life (72 hours) in the human body, enabling sustained regulation of calcium metabolism. Additionally, the crystalline form enhances storage stability and compatibility with various formulations, making it more suitable for long-term use products.
Q2: What is the bioavailability of Vitamin K2 MK-7 Crystal 98%?
A2: The combination of crystalline structure and natural fermentation origin ensures excellent bioavailability. It is well-absorbed in the intestines after oral intake, with no significant first-pass metabolism in the liver, efficiently converting to active forms to support health.
Q3:Is safe for long-term use?
A3:Yes, it is safe for long-term use at the recommended dosage. It is a naturally derived ingredient with no reported severe side effects. It complies with global safety standards for food, cosmetics, and pharmaceuticals, suitable for long-term formulation applications.
