Vitamin D-3 25000 IU w/ K2 MK-7 (60 capsules) by Metabolic Maintenance

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. 

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.

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.*

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.

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]
