What to Look For in a D3 + K2 Supplement

When you're shopping for a D3 and K2 combo, it's important to check the dosages and forms. Our Aussie-friendly formula provides 5,000 IU of vitamin D3 (as cholecalciferol from lanolin) and 120 mcg of vitamin K2 (as menaquinone-7, MK-7), plus 55 mg of calcium to help absorption. The MK-7 form of vitamin K2 has a longer half-life than MK-4, giving you consistent support throughout the day. These tablets are manufactured in the USA in an FDA-registered facility and have been third-party tested for purity and potency, so you're getting a high-quality product.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 work hand in hand to support your body's calcium handling. D3 helps absorb calcium from food, while K2 directs that calcium to your bones and teeth rather than letting it settle in soft tissues. This teamwork helps keep your bones strong and your heart healthy by promoting proper calcium distribution. Taking them together maximises the benefits of your supplement routine.

Key Health Benefits

Strong Bones: By helping your body use calcium effectively, this combo supports bone mineral density and keeps your skeleton strong.*

Immune Support: Vitamin D3 is well known for its role in immune defence, helping your body fight off seasonal nasties.*

Heart Health: Vitamin K2 helps maintain arterial flexibility and keeps calcium where it belongs, supporting overall cardiovascular wellbeing.*

Dental Health: Proper calcium distribution also means stronger tooth enamel and healthier gums.*

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) is crucial for calcium absorption. It boosts the production of calcium-binding proteins in the intestine, so your body can use dietary calcium. Vitamin K2, specifically as MK-7, activates osteocalcin, a protein that binds calcium to the bone matrix. It also activates matrix GLA protein (MGP), which helps keep arteries flexible by preventing calcium deposits in blood vessels. This coordinated action promotes optimal bone density and heart health.

Frequently Asked Questions

Can I take D3 and K2 separately? You can, but taking them together optimises calcium utilisation. Many studies show the combination offers better benefits for bone and heart health.

What is the best time to take this supplement? Since vitamin D is fat-soluble, taking it with a meal containing healthy fats improves absorption. Take one tablet daily with food.

Are there any interactions with medications? If you're on blood thinning medication (e.g., warfarin), speak to your GP before use, as vitamin K can interact. Also, if you have any medical conditions or are pregnant or breastfeeding, consult your healthcare professional before starting any new supplement.

Recommended Dosage

Take one (1) tablet daily with a meal. Don't exceed the recommended dose. Store in a cool, dry place. Keep out of reach of children. Always read the label and follow the directions for use.
