NOW Supplements, Vitamin D3 and K2, 1,000 IU/45 mcg, Cardiovascular Support*, Supports Bone Health*, 120 Vegetarian Capsules

Vitamin D3 and K2 work together to help your body uses calcium effectively. This supplement from NOW Foods provides a convenient daily dose of both nutrients in one capsule.

How Vitamin D3 and K2 Work Together

Vitamin D3 (cholecalciferol) helps the body produce calcium-binding proteins in the gut, improving calcium absorption. Meanwhile, vitamin K2 (menaquinone) activates osteocalcin, which attaches calcium to the bone matrix, and matrix GLA protein, which helps keep calcium out of blood vessels. That's why many health care professionals suggest taking D3 and K2 as a combination. This formula uses MK-7, a form of K2 with a longer half-life than MK-4, ensuring steady support throughout the day.

Key Health Benefits

• Bone Health: Vitamin D3 contributes to normal calcium absorption, while vitamin K2 helps incorporate calcium into bone tissue, supporting strong and dense bones.
• Calcium Metabolism Support: By aiding proper calcium distribution, K2 supports normal utilisation of calcium, benefitting both bone and cardiovascular health.
• Immune Function: Vitamin D3 is known to help maintain a healthy immune response.
• Dental Health: Both nutrients play a role in supporting strong teeth and oral health.

Why Take Vitamin D3 and K2 Together?

Taking vitamin D3 and K2 together makes sense because they complement each other. Vitamin D3 boosts calcium absorption from the gut, and K2 then directs that calcium to bones and teeth, preventing it from depositing in arteries. This teamwork is key for maintaining strong bones and a healthy cardiovascular system.

Many people take D3 on its own, but without enough K2, calcium may not be used correctly. Combining them ensures your body puts calcium to good uses.

Recommended Dosage

The suggested serving is one capsule per day, delivering 1,000 IU of vitamin D3 and 45 mcg of vitamin K2 (as MK-7). This dose is appropriate for most adults aiming to maintain healthy bones and cardiovascular function.
