This product is an excellent representation of a high-quality Vitamin K supplement, featuring 100mcg of the superior Menaquinone-7 (MK-7) form. It offers a potent and highly bioavailable option for fulfilling Vitamin K requirements.
Goals
With 100 mcg of MK-7, this product strongly supports bone health by activating osteocalcin, a protein crucial for integrating calcium into the bone matrix. This promotes healthy bone mineralization and contributes to overall bone strength and density.
The MK-7 in this supplement is highly effective for heart health by activating matrix Gla protein (MGP), which actively prevents calcium from depositing in arterial walls. This mechanism is vital for maintaining arterial elasticity and plays a significant role in reducing cardiovascular risk factors.
By preventing the calcification of soft tissues and arteries, this Vitamin K2 supplement provides robust cardiovascular support. It helps ensure that calcium is utilized properly by the body, supporting the integrity and function of the circulatory system for overall vascular health.
