Vitamin K2 supports blood clotting and bone health
Vitamin K2, also known as menaquinone, supports several important processes in the body. It contributes to normal blood clotting and supports calcium incorporation into bones. This function helps maintain strong bones.
Different forms of vitamin K
Vitamin K exists mainly as vitamin K1 and vitamin K2. Vitamin K1 occurs mainly in leafy vegetables such as kale, endive, and spinach. Vitamin K2 occurs in small amounts in animal products such as meat, eggs, and dairy, and in fermented foods such as natto.
Why combine vitamins D and K
Vitamin D3 and K2 work together in calcium metabolism. Vitamin D3 increases calcium absorption from food but does not control where calcium is stored. Vitamin K2 helps direct calcium into bones where it is needed. Together, vitamin D3 and K2 help maintain strong bones and support proper calcium use in the body.
Best absorbed form of vitamin D
Vitamin D occurs as ergocalciferol (D2) from plant sources and cholecalciferol (D3) from animal sources. Vitamin D3 matches the form the body produces in the skin under sunlight exposure and is therefore efficiently absorbed. The vitamin D3 in these tablets comes from wool of living sheep in Australia and New Zealand, which allows a vegetarian-friendly source while maintaining high absorption.
Vitamin K2 in the best absorbed MK-7 form
Vitamin K2 appears in several forms labeled MK-4 through MK-14. These tablets use menaquinone-7 (MK-7), which is stable and efficiently absorbed. Vitamin K1 remains active in the body for only a few hours, while MK-7 remains active for more than 72 hours. This allows distribution to bones, blood vessels, and other tissues.
Naturally produced vitamin K2
The vitamin K2 comes from natural fermentation using Bacillus subtilis natto. Standardization ensures each tablet provides 40 mcg vitamin K2, which guarantees consistent quality and dosage.
