What to Look For in a D3 + K2 Supplement
Not all vitamin D3 and K2 supplements are created equal. When choosing a product, consider the following factors:
-
Form of K2: Look for MK-7 (menaquinone-7), which has a longer biological half-life than MK-4 and requires only once-daily dosage. Micro Ingredients uses premium MK-7.
-
Dosage Ratio: A common effective ratio is 5,000 IU of D3 to 100 mcg of K2. This provides a potent dose of D3 while ensuring enough K2 to activate calcium-directing proteins.
-
Delivery Vehicle: Because D3 and K2 are fat-soluble, a carrier oil like virgin coconut oil aids absorption. This product’s coconut oil softgels provide that advantage.
-
Purity & Testing: Third-party lab testing ensures the supplement is free from contaminants and matches label potency. Micro Ingredients is non-GMO and free from soya, dairy, gluten, preservatives, and artificial flavours.
Why Take Vitamin D3 and K2 Together?
Vitamin D3 and vitamin K2 are two essential fat-soluble nutrients that work in concert to support your body’s calcium metabolism. While vitamin D3 helps increase calcium absorption from the digestive tract, vitamin K2 helps direct that calcium to the bones and teeth where it belongs — and away from soft tissues like arteries. This synergistic partnership makes the combination far more effective than taking either nutrient alone.
Many people supplement with vitamin D3 without considering K2, but emerging research suggests that without adequate K2, calcium absorbed thanks to D3 may not be properly utilised. By taking both together, you help ensure calcium supports strong bones and a healthy cardiovascular system. Micro Ingredients combines 5,000 IU of vitamin D3 (as cholecalciferol) with 100 mcg of vitamin K2 (as menaquinone-7) in a single, convenient soft gel capsule.
Key Health Benefits
Bone Health & Teeth Support: Vitamin D3 contributes to normal absorption and utilisation of calcium and phosphorus, while vitamin K2 contributes to the maintenance of normal bones. This duo helps maintain strong, dense bones and healthy teeth.
Immune Function: Vitamin D3 is well-known for its contribution to the normal function of the immune system. By helping maintain healthy vitamin D levels, this supplement may help your immune system respond effectively to seasonal challenges.
Heart Health: Vitamin K2’s role in activating matrix GLA protein supports arterial flexibility and normal calcium balance in the cardiovascular system. This may contribute to long-term heart health.
Joint Health: By supporting calcium utilisation in bone and cartilage, the D3 + K2 combination may help maintain comfortable joint function and mobility.

Understanding the Synergy: How D3 and K2 Work Together
The synergy between D3 and K2 is rooted in their complementary roles at the molecular level. Vitamin D3 stimulates the production of calcium-binding proteins in the intestines, which help transport calcium into the bloodstream. Vitamin K2, on the other hand, activates two key proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which may help prevent calcium from depositing in blood vessel walls.
Without sufficient K2, the calcium mobilised by D3 can remain in circulation instead of being incorporated into bone. This is why the combination is so important for long-term bone health and arterial flexibility. The MK-7 form of vitamin K2 used here is particularly effective because it has a longer half-life in the body compared to MK-4, allowing for more sustained activation of these proteins.
Micro Ingredients enhances absorption by including virgin coconut oil as a carrier. Since vitamins D and K are fat-soluble, taking them with a healthy fat source like coconut oil helps ensure optimal bioavailability. Each soft gel capsule delivers D3 and K2 in a base of pure virgin coconut oil, making the nutrients readily available for your body to uses.
Recommended Dosage
Adults take one (1) soft gel capsule daily with a meal, or as directed by a health care professional. Each soft gel capsule provides 5,000 IU of vitamin D3 (as cholecalciferol) and 100 mcg of vitamin K2 (as menaquinone-7). Do not exceed the recommended dose. Keep out of reach of children.

Frequently Asked Questions
What is the best time to take vitamin D3 and K2?
Since these vitamins are fat-soluble, take them with a meal that contains healthy fats for maximum absorption. Many people take them with breakfast or lunch. The coconut oil in the softgels already provides fat, but taking with food enhances it further.
Can I take vitamin D3 and K2 if I am on blood thinners?
If you are taking anticoagulant medications like warfarin (Coumadin), consult your health care provider before taking vitamin K2, as it may interfere with the medication’s mechanism. K2 is generally considered safe for most people, but medical guidance is essential.
Is MK-7 safe for long-term uses?
Yes, MK-7 is widely studied and considered safe for long-term supplementation at doses up to 100 mcg per day. Always follow the recommended dosage and consult your health care provider for personalized advice.
