Member's Mark Vitamin K2 180 mcg + D3 125 mcg, 150 Soft gel capsules

Key Health Benefits

Vitamin D3 and K2 work together to support your body’s calcium management. Vitamin D3 contributes to normal calcium absorption, whilst vitamin K2 helps direct that calcium to the bones and teeth where it’s needed, away from soft tissues. This synergistic pair is essential for maintaining strong bones and a healthy cardiovascular system. Each soft gel capsule provides 180 mcg of vitamin K2 (as MK-7) and 125 mcg (5000 IU) of vitamin D3, offering a balanced ratio for daily supplementation.

• Bone Health: Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, and vitamin K contributes to maintenance of normal bones.*
• Heart Health: Vitamin K2 supports normal calcium distribution, which may help maintain arterial flexibility.*
• Immune Support: Vitamin D contributes to the normal function of the immune system.*
• Dental Health: By directing calcium to teeth, vitamin K2 supports dental mineralisation.*

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) is well-known for its role in calcium absorption. It helps the body absorb calcium from food, making it available for undertake. However, without sufficient vitamin K2, that calcium may end up in the wrong places. Vitamin K2 activates proteins such as osteocalcin and matrix GLA protein (MGP). Osteocalcin helps bind calcium to the bone matrix, while MGP helps prevent calcium from depositing in the blood vessel walls. This teamwork helps maintain normal calcium balance and supports both bone density and arterial flexibility. The combination of 180 mcg of K2 (as MK-7, a form with a longer half-life) and 125 mcg (5000 IU) of D3 provides a balanced ratio optimised for daily supplementation. Member's Mark delivers these nutrients in a small, easy-to-swallow soft gel capsule.

Why Take Vitamin D3 and K2 Together?

Whilst you can take vitamin D3 and K2 separately, taking them together ensures optimum absorption and calcium routing. The pair is designed to work together for maximum benefit. Vitamin D3 is fat-soluble, so take with a meal containing healthy fats; the soft gel capsules contain a small amount of oil for absorption. When taken as directed, side effects are rare. However, high doses of D3 may cause toxicity over time, so always adhere to the recommended serving.
