Doctor's Best Vitamin D3 and K2 Supplement for Men & Women - Vitamin D3 5000 IU + K2 as MK-7, Bone Health Support, Gluten-free, Non GMO, Vegetarian Capsules - 60 Veg Caps

Understanding the Synergy: How D3 and K2 Work Together

When you consume vitamin D3, it stimulates the production of calcium-binding proteins in the gut, enhancing calcium absorption. Vitamin K2 then activates two key proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium from depositing in blood vessels. This partnership supports both strong bones and cardiovascular health.*

Key Health Benefits

• Bone Strength: Vitamin D3 contributes to normal calcium absorption, while K2 helps incorporate calcium into bone tissue, supporting bone mineral density.
• Heart Health: By activating MGP, K2 helps maintain arterial flexibility and promotes normal calcium balance in the cardiovascular system.*
• Immune Support: Vitamin D3 is known to help support normal immune function, helping your body defend against seasonal challenges.*
• Dental Health: Proper calcium utilisation supports strong teeth and healthy tooth enamel.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 helps your body absorb calcium from food. But calcium needs proper direction—without guidance, it can accumulate in soft tissues. That’s where vitamin K2 steps in. K2 activates proteins that help direct calcium to bones and teeth, where it belongs, and supports healthy arterial flexibility. Together, they form a synergistic duo for overall wellness.

What to Look For in a D3 + K2 Supplement

Not all combinations are equal. This formula provides 5000 IU (125 mcg) of vitamin D3 as cholecalciferol and 100 mcg of vitamin K2 as menaquinone-7 (MK-7). MK-7 is the preferred form because it stays active in the body longer than MK-4, offering sustained support. The supplement is non-GMO, gluten-free, and vegetarian—suitable for a wide range of dietary preferences. Third-party testing ensures purity and potency.

Recommended Dosage

Take one capsule daily with food, or as directed by a health care professional. Each bottle provides a 60-day supply. As with any supplement, consult your doctor before starting a new regimen.
