Vitamin D-A-K 60 Capsules by Natura Health Products

Vitamin D-A-K by Natura Health Products is a professional-grade fat-soluble vitamin formula designed to support healthy bone density, promote normal cardiovascular function, and maintain balanced immune activity. This 60-capsule formula delivers clinically relevant doses of Vitamins D3, A, and K2 in their most bioavailable forms, working synergistically to direct calcium to the right tissues and support whole-body structural and metabolic health.

Key Benefits of Fat-Soluble Vitamins and Synergistic Cofactors

• Vitamin D3 (as Cholecalciferol): The most bioavailable form of Vitamin D, supporting healthy calcium absorption, promoting normal immune cell function, and maintaining healthy bone mineralization and muscle function.
• Vitamin A (as Retinyl Palmitate): A preformed, highly bioavailable source of Vitamin A that supports healthy vision, promotes normal immune barrier function, and maintains healthy skin and mucosal tissue integrity.
• Vitamin K2 (as Menaquinone-7, MK-7): The most bioavailable and longest-acting form of Vitamin K2, supporting healthy calcium utilization by activating osteocalcin for bone matrix deposition and matrix Gla-protein (MGP) for vascular tissue protection.
• Calcium Metabolism Support: The D3-A-K2 combination works synergistically to promote healthy calcium absorption from the gut, direct calcium into bone tissue, and maintain normal calcium clearance from soft tissues and vascular walls.
• Bone Structural Support: Vitamins D3 and K2 together support healthy osteoblast activity and normal bone remodeling, maintaining bone density and structural integrity across the lifespan.
• Cardiovascular Function Support: Vitamin K2 as MK-7 activates MGP, a key protein that supports healthy vascular flexibility and promotes normal calcium metabolism in arterial tissue.
• Immune System Modulation: Vitamin D3 supports healthy innate and adaptive immune cell activity, and Vitamin A promotes normal mucosal immune barrier function, together maintaining a balanced immune response.
• Skin and Mucosal Tissue Integrity: Vitamin A supports healthy epithelial cell turnover and promotes normal mucosal tissue function throughout the respiratory, digestive, and urinary tracts.

Why This Formula Matters

Vitamins D3, A, and K2 are fat-soluble nutrients that function as a coordinated system rather than independent compounds, and supplementing D3 without adequate K2 may allow calcium to accumulate in soft tissues rather than being directed to bone. The use of MK-7, the long-chain form of Vitamin K2, ensures sustained activity over a 24-hour period, providing consistent support for calcium routing and vascular tissue protection that shorter-acting forms such as MK-4 cannot maintain. By combining all three fat-soluble vitamins in their most bioavailable forms at clinically informed doses, Vitamin D-A-K provides a complete and balanced approach to bone, cardiovascular, and immune support that isolated Vitamin D supplements cannot replicate.

Frequently Asked Questions

What is Vitamin D-A-K used for?

Vitamin D-A-K is a fat-soluble vitamin formula designed to support healthy bone density, promote normal cardiovascular function, and maintain balanced immune activity. It is intended for adults seeking comprehensive support for calcium metabolism, bone structural health, and immune function through a synergistic combination of Vitamins D3, A, and K2.

How do I take Vitamin D-A-K?

The recommended use is 1 capsule once per day, or as directed by a qualified healthcare practitioner. Because Vitamins D, A, and K are fat-soluble, this product is best taken with a meal containing dietary fat to support optimal absorption.

Why does this formula include Vitamin K2 with Vitamin D3?

Vitamin D3 promotes calcium absorption from the digestive tract, and Vitamin K2 activates the proteins responsible for directing that calcium into bone tissue and away from soft tissues such as arterial walls. Taking D3 without adequate K2 may result in calcium being absorbed but not properly routed, which is why this combination is considered clinically important by many integrative practitioners.

What is the difference between MK-4 and MK-7 forms of Vitamin K2?

MK-7 is a long-chain form of Vitamin K2 derived from fermented natto that remains active in the body for approximately 72 hours, compared to MK-4 which has a much shorter half-life of a few hours. This extended activity makes MK-7 more effective for maintaining consistent support for bone and vascular calcium metabolism with once-daily dosing.

Is Vitamin D-A-K safe for long-term use?

Fat-soluble vitamins accumulate in the body over time, and long-term use at higher doses should be monitored by a healthcare provider. At the doses provided in this formula, daily use is generally well tolerated for most adults. Periodic assessment of Vitamin D serum levels is recommended for individuals using Vitamin D supplements on an ongoing basis.

Can Vitamin D-A-K be taken with other supplements or medications?

Vitamin K2 may interact with anticoagulant medications such as warfarin. Individuals taking blood thinners or other medications that affect clotting should consult their healthcare provider before using this product. Vitamin A at high cumulative doses may also interact with certain medications, so professional guidance is recommended for individuals on complex medication regimens.
