DAVINCI Labs ADK - Vitamin A, D3 & K2 (MK-7) Supplement - 30 Capsules

Understanding the Synergy: How D3, K2 and A Work Together

Vitamin D3 stimulates the production of calcium-binding proteins in the gut, enhancing calcium absorption. Vitamin K2 then activates osteocalcin, a protein that helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which may help prevent calcium deposition in blood vessels. Vitamin A plays a complementary role by supporting bone remodelling and immune cell function.

This triad of nutrients helps maintain proper calcium balance and supports bone density, heart health and immune resilience. DAVINCI Labs ADK delivers each vitamin in clinically relevant forms and doses, ensuring optimal absorption and activity.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 work synergistically to optimise calcium utilisation in the body. While vitamin D3 increases calcium absorption from the gut, vitamin K2 helps direct that calcium to the bones and teeth—where it belongs—and away from soft tissues like arteries. This partnership is essential for maintaining strong bones and a healthy cardiovascular system. Without sufficient K2, calcium absorbed thanks to D3 may accumulate in unwanted areas.

DAVINCI Labs ADK combines vitamins A, D3 and K2 in one convenient capsule, making it easier to support these critical processes. The formula includes vitamin K2 as MK-7, known for its bioavailability and long-lasting activity. This ensures steady support throughout the day.

Key Health Benefits

• Bone Health: Supports calcium absorption, bone density and proper bone remodelling. Vitamin A contributes to the maintenance of normal bone structure.
• Heart Health: Helps maintain arterial flexibility by supporting normal calcium balance. Vitamin K2’s activation of MGP may help keep calcium out of arterial walls, supporting circulatory function.
• Immune Support: Vitamin D3 helps support normal immune function, while vitamin A contributes to the normal function of the immune system.
• Dental Health: By directing calcium to teeth, this combination helps support strong tooth enamel and overall oral health.

Together, these nutrients work synergistically to maintain optimal calcium homeostasis, which is crucial for long-term bone and cardiovascular health. The inclusion of vitamin K2 as MK-7 ensures prolonged activation of vitamin K-dependent proteins, supporting these processes throughout the day.

What Makes This ADK Formula Unique?

DAVINCI Labs ADK stands out for its thoughtful formulation and quality commitment. Each serving provides 1,500 mcg of vitamin A (as palmitate), 25 mcg (1,000 IU) of vitamin D3 (as cholecalciferol), and 45 mcg of vitamin K2 (as menaquinone-7). These specific forms are chosen for their superior absorption and biological activity. The K2 is present as MK-7, the form with a longer half-life that supports sustained activation of vitamin K-dependent proteins.

The capsule itself is vegetarian—no gelatine—and the product is certified gluten-free and soya-free. Since 1973, DAVINCI Labs has been a leader in nutritional research, emphasising quality and innovation. The tiny capsule size makes it easy to swallow, even for those who struggle with larger pills. Users appreciate that the capsules have no unpleasant taste or aftertaste.

What to Look For in a D3 + K2 Supplement

When choosing a combined D3 and K2 supplement, consider the form and dosage of each nutrient. For vitamin K2, MK-7 is preferred over MK-4 because it remains active in the body longer, requiring fewer daily doses. A typical effective dosage ranges from 45–100 mcg of MK-7 paired with 1,000–5,000 IU of vitamin D3. DAVINCI Labs ADK provides a balanced 45 mcg of MK-7 with 1,000 IU of D3, making it suitable for daily maintenance.

Also check for third-party testing, vegetarian/vegan certifications, and absence of common allergens. DAVINCI Labs’ formula is free from gluten, soya and artificial additives, and is manufactured in a GMP-certified facility. This product is manufactured without the uses of artificial colours, flavours or preservatives. Each batch undergoes rigorous quality control to ensure purity and potency.
