Vitamin D3 25,000 IU with Vitamin K2 MK-7 is high potency vitamin D3 (25,000 IU or 625 mcg) and vitamin K2 (MK-7) designed to support bone health, heart function, and immune balance.*  This pairing ensures calcium is efficiently absorbed and properly utilized where it’s needed most.* Formulated for purity and efficacy. 

Diminished time outside, frequent use of sunscreen, and living at latitudes with scarce winter sunlight can all negatively affect vitamin D levels. Vitamin D’s role in helping the body absorb and retain both calcium and phosphorus is critical to building bone.* It also plays a role in mood balance and immune health.* Monitoring of vitamin D blood levels (25-OH vitamin D) is recommended with higher potency vitamin D3. 

High-potency support for bone, cardiovascular, and immune health.*

What It Does

This formula combines a clinically relevant dose of vitamin D3 with vitamin K2 (MK-7) to promote optimal calcium utilization, supporting healthy bones, heart function, and immune balance.* The nutrients work together to help direct calcium to bones and teeth while maintaining vascular integrity and balanced cytokine signaling.*

How It Works

Vitamin D3 (25,000 IU as Cholecalciferol): Supports calcium and phosphorus absorption for bone mineralization, immune modulation, and musculoskeletal strength.* [1,3] Vitamin D is labeled as both activity (25,000 IU) and mass (625 mcg).

Vitamin K2 (as MK-7, 45 mcg): Activates osteocalcin and matrix Gla protein to help guide calcium to bone and away from soft tissues, supporting cardiovascular elasticity and arterial health.* [2,4]

Dual-Action Formula: The combination of D3 and K2 helps maintain the balance between bone density and vascular integrity, optimizing overall calcium homeostasis.* [2,4]

Who It’s For

Ideal for adults seeking high-potency vitamin D3 support under healthcare practitioner supervision, particularly those with limited sun exposure, higher nutrient requirements, or targeted bone and cardiovascular health goals.*

Special Features

Formulated for professional use with bioactive MK-7 for longer half-life and stability. Manufactured without common allergens or unnecessary additives, ensuring purity and clinical precision.
