Key Health Benefits

Strong Bones and Healthy Teeth

Vitamin D3 supports calcium absorption, and K2 helps deposit that calcium into bones and teeth. This teamwork supports bone density and dental health as you age.* For individuals concerned about age-related bone loss, D3 and K2 may be particularly beneficial.

Immune System Support

Vitamin D3 is essential for normal immune function. It helps regulate the activity of immune cells and supports a healthy inflammatory response. Adding K2 does not interfere with this role—instead, it complements D3 by managing calcium balance.*

Heart Health

By directing calcium away from arteries, vitamin K2 helps maintain arterial flexibility and supports cardiovascular function.* Many people take D3 and K2 specifically for heart health benefits, especially as part of a proactive wellness routine.

Why Take Vitamin D3 and K2 Together?

Many individuals take vitamin D for its well-known effects, but few recognise that adding vitamin K2 can significantly boost its efficacy. Vitamin D3 helps your body absorb calcium from food, while vitamin K2 directs that calcium towards your bones and teeth—and away from soft tissues like arteries. This synergy makes D3 and K2 a powerful combination for maintaining strong bones, supporting immune function, and promoting cardiovascular health.*

Without enough K2, calcium absorbed thanks to D3 may end up in the wrong places. In fact, research suggests that taking D3 alone could potentially contribute to arterial calcification if K2 levels are insufficient. Our Vitamin D3 K2 supplement provides an optimal ratio of 5000 IU D3 to 100 mcg K2 (as MK-7) to help you get the most out of both nutrients.

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) plays a key role in calcium metabolism by promoting the production of calcium-binding proteins in the intestines. This increases calcium absorption from your diet. However, calcium doesn't automatically go where it is needed most. That's where vitamin K2 comes in.

Vitamin K2 activates two crucial proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix Gla protein (MGP), which helps prevent calcium buildup in blood vessels and soft tissues. By activating these proteins, K2 ensures that calcium is deposited in bones and teeth, not in arteries. This complementary action is why many experts recommend taking vitamin D3 and K2 together for optimal skeletal and cardiovascular support.*

Our formula uses the MK-7 form of K2 (menaquinone-7), which is known for its longer half-life in the body compared to MK-4. This means it stays active longer, providing sustained support throughout the day.

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are created equal. Here are key factors to consider when choosing a product:

  • Form of K2: MK-7 (as used in our formula) is preferred over MK-4 because it remains active in the body for up to 24 hours, allowing for once-daily dosage. MK-4 requires multiple doses throughout the day.
  • Dosage Ratio: A common effective ratio is 5000 IU D3 to 100 mcg K2 (MK-7), which provides a meaningful amount of both nutrients without overdoing it. This is the ratio we uses.
  • Bioavailability: Fat-soluble vitamins like D3 and K2 are best absorbed when taken with a meal that contains healthy fats. Our chewable tablets are designed for convenience and can be taken with or without food—but for optimal absorption, we recommend taking them with a small amount of fat.
  • Purity: Our formula is non-GMO and free from common allergens. Always check labels for third-party testing or quality seals. (Our product is manufactured in a cGMP facility.)

What Makes Our Chewable Vitamin D3 K2 Special?

Many D3 and K2 supplements come in large capsules or softgels that are hard to swallow. We created a delicious chewable tablet with a natural berry flavour that makes taking your daily vitamins a pleasure, not a chore. Each bite-sized tablet delivers 5000 IU of vitamin D3 and 100 mcg of K2 (MK-7) in a tasty, convenient form. They're perfect for adults who dislike swallowing pills, or anyone who wants a more enjoyable supplement experience.

Our formula is carefully crafted to ensure maximum freshness and potency. We uses high-quality ingredients and rigorous testing to provide a product you can trust. Plus, being non-GMO and free from artificial colours or preservatives, this supplement aligns with a clean lifestyle.

Frequently Asked Questions

Can I take vitamin D3 and K2 separately? Yes, but taking them together in a balanced formula ensures you get the right ratio and simplifies your supplement routine. Our product combines both in one tablet for convenience.

What is the best time to take D3 and K2? Since they are fat-soluble, taking them with a meal that contains healthy fats (like avocado, nuts, or olive oil) can enhance absorption. Many people take them with breakfast or lunch.

Are there any side effects? Vitamin D3 and K2 are generally well tolerated. However, high doses of D3 can cause toxicity over time; do not exceed recommended dosages. If you are on blood-thinning medications (e.g., warfarin), consult your health care provider before taking K2 supplements, as K2 can interact with these drugs.

Is this product suitable for vegans? Our vitamin D3 is derived from lanolin (sheep's wool), so it is not vegan. The K2 (MK-7) is from a synthetic source, which is considered vegan-friendly. For a vegan option, look for a D3 from lichen.

Recommended Dosage

For adults, take one chewable tablet daily with food. Do not exceed the suggested uses. Each tablet provides 5000 IU (125 mcg) of vitamin D3 and 100 mcg of vitamin K2 (as MK-7). These amounts are appropriate for most adults looking to maintain healthy vitamin D levels and support calcium metabolism. If you have specific health concerns or are pregnant/nursing, consult your health care professional before uses.
