Key Health Benefits
Taking vitamin D3 and K2 together offers a range of benefits for your body. This dynamic duo helps maintain strong bones by ensuring calcium is absorbed and directed to where it's needed most. It also supports healthy muscle function, which is vital for everyday movement and coordination. Additionally, the combination promotes cardiovascular wellbeing by keeping arteries flexible, and it gives your immune system a helpful boost.*
-
Bone Health Support: Vitamin D3 boosts calcium absorption, while vitamin K2 helps bind calcium to the bone matrix. Together they help maintain normal bone density and structure.*
-
Healthy Muscle Function: Adequate vitamin D levels are linked to muscle strength and coordination. K2 also plays a role in muscle cell metabolism, helping promote healthy muscle function and mobility.*
-
Calcium & Phosphorus Balance: Vitamin D3 helps maintain the proper balance of calcium and phosphorus in the blood, essential for many body processes.*
-
Cardiovascular Wellbeing: By activating matrix GLA protein (MGP), vitamin K2 helps maintain arterial flexibility, supporting a healthy circulatory system.*
-
Immune Support: Vitamin D3 is well-known for its role in normal immune function.*
Why Take Vitamin D3 and K2 Together?
Vitamin D3 and K2 are often talked about separately, but they work best as a team. Vitamin D3 (cholecalciferol) helps your body absorb calcium from food. But without enough vitamin K2, that calcium might end up in soft tissues like arteries instead of your bones and teeth. Vitamin K2, especially as menaquinone-7 (MK-7), activates proteins that guide calcium to your skeleton. Taking them together maximises calcium use, helping keep bones strong and muscles working properly.*
This combination is especially valuable as you age to support bone density, maintain cardiovascular health by keeping arteries flexible, and promote overall wellbeing. Nordic Naturals Vitamin D3 + K2 Gummies are a convenient, great-tasting way to get both nutrients in one serve.
Understanding the Synergy: How D3 and K2 Work Together
To really appreciate how they work together, let's look at the cellular level. Vitamin D3 binds to receptors in the intestines, telling them to make calcium-binding proteins that increase calcium absorption. This raises blood calcium levels, but without K2, there's no clear direction for where that calcium should go.
Vitamin K2 activates two key proteins: osteocalcin (in bones) and matrix GLA protein (MGP) (in blood vessels). Osteocalcin helps incorporate calcium into the bone matrix, strengthening your skeleton. MGP helps stop calcium from building up in arterial walls. So D3 increases calcium availability, and K2 ensures it's used safely and effectively. This teamwork supports both bone density and cardiovascular flexibility.*
Nordic Naturals uses vitamin D3 as cholecalciferol (the most bioavailable form) and vitamin K2 as MK-7 (the most bioactive form with a longer half-life than MK-4). This gives you sustained action throughout the day.
What to Look For in a D3 + K2 Supplement
When choosing a vitamin D3 and K2 supplement, a few things matter. Look for cholecalciferol (D3) rather than ergocalciferol (D2), because D3 is used more effectively by the body. For K2, menaquinone-7 (MK-7) is preferred because it lasts longer and is more bioavailable than MK-4.
Dosage is also important. Nordic Naturals provides 1000 IU of vitamin D3 and 45 mcg of vitamin K2 (as MK-7) per serve – a well-researched ratio. Third-party testing ensures purity and potency. This product is Non-GM, gluten free, dairy-free, and contains no artificial colors or flavours. The pomegranate flavour comes from natural sources, making the gummies enjoyable to take every day.
Ethical sourcing counts too. Nordic Naturals is committed to sustainable practices and rigorous quality standards, verified by third-party testing.
Recommended Dosage
For adults, take one gummy daily, preferably with a meal. Each gummy gives you 1000 IU (25 mcg) of vitamin D3 and 45 mcg of vitamin K2 (as MK-7). This aligns with general wellbeing recommendations for maintaining healthy bones, muscles, and immune function. Don't exceed the recommended serve unless your healthcare professional tells you to.
Always read the label and follow the directions for use. If symptoms persist, talk to your health professional.
Frequently Asked Questions
Can I take vitamin D3 and K2 with other medications?
If you're taking blood thinners (like warfarin), check with your doctor before taking vitamin K2, as it can affect how they work. Vitamin D3 may also interact with some medications. Always discuss new supplements with a medical professional.
What's the best time to take these gummies?
Vitamin D3 is fat-soluble, so taking the gummies with a meal containing fat may help absorption. But the gummy format is convenient, and you can take them any time. Being consistent is what matters most.
Are these gummies suitable for vegans?
The gummies are gelatine-free and vegetarian, but they may contain ingredients from animal sources (like vitamin D3 from lanolin). Check the label if you need vegan certification.
