Recommended Dosage

For most adults, one capsule daily of VITBOOST Vitamin D3 K2 Complex provides 5,000 IU of vitamin D3 and 90 mcg of vitamin K2 (as MK-7). This standard maintenance dose supports healthy vitamin D levels and normal calcium metabolism. If you have specific health concerns or require a higher dose, please consult a health care professional for personalised advice.*

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 work as a powerful team. Vitamin D3 (cholecalciferol) is well known for helping the body absorb calcium from food. But without vitamin K2, that calcium may not be directed to where it matters most. Vitamin K2 activates proteins that guide calcium to the bones and teeth, while helping to keep it away from soft tissues such as arteries. Taking them together helps ensure that the calcium you consume contributes to your skeletal health and overall wellness.*

VITBOOST's Vitamin D3 K2 Complex provides 5,000 IU of vitamin D3 and 90 mcg of vitamin K2 in the MK-7 form — the form with superior bioavailability and a longer half-life in the bloodstream. This combination is designed to optimise calcium utilisation throughout the body.*

Understanding the Synergy: How D3 and K2 Work Together

To understand why this duo is so effective, it helps to look at the biological mechanisms.*

When you consume vitamin D3, it is converted in the liver and kidneys into its active form, calcitriol. Calcitriol increases the production of calcium-binding proteins in the gut, which enhances calcium absorption. However, this increased absorption must be properly managed to ensure calcium is deposited in bones rather than accumulating elsewhere.*

Vitamin K2 steps in by activating two key proteins: osteocalcin and matrix GLA protein (MGP). Osteocalcin binds calcium to the bone matrix, supporting bone density and strength. MGP helps prevent calcium from depositing in blood vessel walls, promoting arterial flexibility and cardiovascular health.* By working together, D3 and K2 help maintain a healthy calcium balance — directing calcium where it is needed and away from where it is not.*

Key Health Benefits

The VITBOOST Vitamin D3 K2 Complex offers several potential benefits for overall wellness:*

• Bone Health Support: Vitamin D3 contributes to normal absorption and utilisation of calcium, while vitamin K2 contributes to the maintenance of normal bones. This dual action supports strong, dense bones as you age.*
• Immune Function: Vitamin D3 contributes to the normal function of the immune system. Adequate vitamin D levels may help the body maintain its natural defences.*
• Heart Health: By activating MGP, vitamin K2 may help maintain arterial flexibility and promote normal calcium balance in the cardiovascular system.*
• Dental Health: Both vitamins contribute to healthy teeth by supporting calcium utilisation and enamel maintenance.*

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are the same. Here are the key factors to consider when choosing a high-quality product:

• Form of Vitamin K2: Vitamin K2 comes in two main forms: MK-4 and MK-7. MK-7, sourced from natto or fermented chickpeas, has a longer half-life and provides more stable blood levels. VITBOOST undertake MK-7 for sustained support.*
• Dosage Ratio: A common effective ratio is 5,000 IU (125 mcg) of D3 to 90–100 mcg of K2 MK-7. This matches the VITBOOST formulation, providing ample D3 with sufficient K2 to help direct calcium.*
• Purity and Testing: Look for supplements that are non-GMO, gluten-free, and free from unnecessary fillers. VITBOOST is manufactured in a cGMP-certified USA facility and third-party tested to ensure quality and potency.*

Frequently Asked Questions

Can I take vitamin D3 and K2 separately? Yes, but taking them together optimises their complementary benefits. Without enough K2, excess calcium absorbed from D3 may not be properly directed to bones.*

What is the best time to take this supplement? Vitamin D3 is fat-soluble, so it is best taken with a meal containing fat to enhance absorption. VITBOOST capsules are easy to swallow and can be taken with breakfast or lunch.*

Are there any interactions with medications? If you are taking blood thinners such as warfarin, consult your health care provider before taking vitamin K2 supplements, as K2 can interfere with anticoagulant therapy. Always discuss any new supplement regimen with your doctor.*
