K-Right: Bone Health, Cardiovascular Health and Optimal Coagulation – The Synergy of Vitamin D₃ and Advanced Forms of Vitamin K for Metabolic Balance and Longevity

K-Right from Jarrow Formulas is an advanced dietary supplement, formulated to support bone system health, cardiovascular system and essential coagulation functions. This synergistic combination of Vitamin D₃ (cholecalciferol) and the three forms of Vitamin K – K₁ (phylloquinone), K₂ in the form of MK-4 (menaquinone-4) and K₂ in the form of MK-7 (menaquinone-7) – offers a complete and modern approach for maintaining calcium homeostasis, protecting arteries and strengthening bone structure.

Vitamin D₃ plays a central role in calcium absorption at the intestinal level and in immune system functioning. However, without the adequate presence of K vitamins, absorbed calcium can be incorrectly directed to soft tissues (such as blood vessels), instead of reaching where it is truly needed – in bones. K-Right optimizes this essential relationship between D₃ and K, ensuring a correct distribution of calcium, reducing the risk of vascular calcification and supporting bone system resistance in the long term.



 

Detailed Benefits of the K-Right Formula – Vitamin D₃ + Vitamin K₁ + Vitamin K₂ (MK-4 & MK-7)

 

• Support for cardiovascular health and prevention of vascular calcifications

One of the most important recent discoveries in nutritional medicine is the role of vitamin K₂ in preventing vascular calcifications – a common problem with advancing age. When vitamin D₃ increases calcium absorption, it is essential that this calcium is efficiently transported to bone tissues and not to blood vessel walls. This is where the advanced forms of Vitamin K come in, especially MK-4 and MK-7, which activate proteins such as Matrix Gla-Protein (MGP) – a natural inhibitor of arterial calcification.

✅ MK-7 and MK-4 help reduce calcium accumulation in arteries
✅ Vitamin K activates proteins necessary for maintaining vessel elasticity
✅ D₃ + K synergy prevents endothelial dysfunctions associated with cardiovascular diseases
✅ Protects the circulatory system and supports normal blood flow

Through this concerted action, K-Right becomes a valuable ally in preventing premature aging of blood vessels, maintaining blood pressure within optimal parameters and reducing the risk of major cardiovascular events.

 

• Strengthening the bone system and calcium metabolism

To build strong and durable bones, the body needs not just calcium, but also a finely balanced regulatory system, in which Vitamin D₃ facilitates calcium absorption, and Vitamin K fixes it in the bone structure. The active forms MK-4 and MK-7 of vitamin K₂ activate osteocalcin, an essential protein for bone mineralization.

✅ Vitamin D₃ increases calcium absorption at the intestinal level
✅ Vitamin K₂ activates osteocalcin, directing calcium into bones
✅ Combining MK-4 and MK-7 provides rapid action (MK-4) and long-lasting effect (MK-7)
✅ Support in preventing osteoporosis and bone fragility

Studies show that adequate vitamin K₂ intake reduces the risk of fractures, increases bone mineral density and supports maintaining a healthy bone structure long-term – especially in postmenopausal women, the elderly and athletes.

 

• Regulation of natural coagulation processes

Vitamin K₁ (phylloquinone), present in the K-Right formula in a concentrated dose, is the main nutrient responsible for supporting the blood coagulation process. It activates several essential coagulation factors in the liver, helping to maintain vascular integrity and prevent internal hemorrhages.

✅ Support for proper blood clot formation
✅ Prevention of excessive or uncontrolled bleeding
✅ Balance between blood fluidity and vessel protection

The combination of Vitamin K₁ and the two forms of K₂ ensures a complete spectrum of coagulation benefits, without disrupting cardiovascular or bone functions.

 

• Metabolic synergy and support for cellular longevity

Through the combined action of vitamins D₃ and K (K₁ + K₂), K-Right positively influences not just the bone and cardiovascular systems, but also fundamental metabolic processes. Vitamin D₃ acts as a hormone, influencing the expression of over 1000 genes involved in immune, metabolic and cellular processes. In parallel, vitamin K activates enzymes involved in cellular stability, anti-inflammatory processes and tissue regeneration.

✅ Supporting phospho-calcium metabolism and mineral balance
✅ Cellular protection against oxidative stress
✅ Reducing chronic inflammation – a major factor in accelerated aging
✅ Support for endocrine and immune functions

Through these mechanisms, K-Right contributes to maintaining an efficient metabolism, protecting cells against premature degeneration and supporting vital functions of the body.

 

• Formula optimized for maximum absorption and bioavailability

Another important aspect that differentiates K-Right is the careful selection of bioactive forms with increased bioavailability. MK-7, for example, has a long half-life (up to 72 hours), which allows a constant and sustained action on calcium metabolism. MK-4, although having a shorter action time, offers rapid absorption and immediate beneficial effects.

✅ 180 mcg MK-7 – long-lasting action
✅ 1500 mcg MK-4 – rapid and efficient effect
✅ 500 mcg K₁ – immediate support for coagulation
✅ 50 mcg D₃ – efficient calcium absorption and immunity support

This well-balanced combination offers a complete spectrum of nutritional support for the key systems of the body, in a form that allows optimal utilization by cells.

 

• Extended benefits for general health

In addition to effects on bone, circulatory and metabolic systems, K-Right brings a series of additional benefits for daily health:

✅ Support for cognitive function and prevention of neurological decline
✅ Maintaining skin health and blood vessel elasticity
✅ Improving muscle function by balancing calcium levels
✅ Reducing the risk of hormonal imbalances associated with vitamin D deficiency

This formula is suitable for all age categories, especially for people at risk of vitamin D or K deficiency, for those with a vegan diet or mineral imbalances, and for anyone who wants a complete approach to health and longevity.
