Fast-Acting Vitamin K2: MK-4 for Cognitive and Healthy Aging
- 1-5 mg per day
- Manufactured in Europe
- Healthy Aging
Vitamin K₂ (MK-4) is the short-chain menaquinone form of vitamin K known for its distinctive biological activity. It plays a key role in calcium metabolism and contributes to bone strength, vascular health, and cognitive wellness.
Why MK-4?
Vitamin K₂ (MK-4) is a highly bioavailable form of vitamin K₂ that supports calcium balance and cognitive performance. Compared to other menaquinones, MK-4 is rapidly absorbed and distributed to key tissues where it contributes to bone and neurological health.
Fast activity
Quickly absorbed and utilized to support vitamin K–dependent physiological processes.
Bone support
Activates proteins such as osteocalcin and matrix Gla protein (MGP), helping maintain bone strength and flexibility.
Cognitive support
Present in neural tissues, where it helps maintain cellular function and antioxidant balance.
Distinct mechanism
Contributes to the activation of proteins linked to vascular and nervous system integrity.
European quality
Produced under ISO 9001 and GMP standards for purity and consistency.
These features make MK-4 an ideal ingredient for formulations focused on bone maintenance, cognitive well-being, and healthy aging.
How It Works
Vitamin K₂ (MK-4) serves as a cofactor for vitamin K–dependent proteins that regulate calcium utilization and tissue integrity. Through this mechanism, MK-4 helps to:
