Vitamin K 90
Within the Vitamin K category, this product excels by offering a comprehensive and high-potency blend of various K forms. This approach addresses the diverse roles of Vitamin K in the body more effectively than single-form supplements. It's a top-tier option for those seeking maximum Vitamin K coverage.
Goals
The broad-spectrum nature of this Super K supplement provides comprehensive general health benefits. By supporting optimal blood clotting, bone health, and cardiovascular function, it addresses multiple vital physiological processes, contributing significantly to overall well-being and longevity. It is an ideal daily supplement for holistic health maintenance.
The inclusion of both MK-4 and MK-7 (inferred from blend) at high dosages makes this product highly effective for bone health. MK-4 helps activate osteocalcin quickly, while MK-7 provides sustained support for calcium integration into bones. This comprehensive approach ensures robust support for bone mineral density.
With both MK-4 and especially MK-7 likely present in significant amounts, this supplement offers excellent heart health benefits. MK-7's long half-life is crucial for activating Matrix Gla Protein, effectively preventing arterial calcification and promoting arterial flexibility. The blend provides a multi-pronged approach to cardiovascular wellness.
