Understanding the Synergy Between D3 and K2
Vitamin D3 and vitamin K2 work together at a molecular level. D3 (cholecalciferol) promotes the production of calcium-binding proteins in the gut, which helps increase calcium uptake. Meanwhile, K2, specifically as menaquinone-7 (MK-7), activates two crucial proteins: osteocalcin and matrix Gla protein (MGP). Osteocalcin helps bind calcium into the bone matrix, while MGP helps prevent calcium from depositing in blood vessel walls. This coordinated action contributes to the maintenance of normal bones and normal blood clotting, as recognized by the European Food Safety Authority (EFSA).
The MK-7 form of vitamin K2 is particularly effective because it remains active in the bloodstream for longer than MK-4. This sustained activity provides consistent support for calcium metabolism. Micro Ingredients uses MK-7 derived from natto (fermented soya), but the final product is processed to remove soya, dairy, and gluten, making it suitable for many dietary requirements. The inclusion of coconut oil in the soft gel capsule provides a convenient fat source that aids the absorption of these fat-soluble vitamins.
Why Take Vitamin D3 and K2 Together?
Vitamin D3 and K2 are fat-soluble nutrients that work in tandem to support several key functions. Vitamin D3 helps increase calcium absorption from the digestive tract, while vitamin K2 helps direct that calcium to the bones and teeth, where it is needed, and away from soft tissues. This synergistic relationship is why many health-conscious individuals choose a combined supplement like Micro Ingredients Vitamin D3 + K2. Taking them together ensures that calcium is properly utilised, supporting strong bones and a healthy cardiovascular system.
Without adequate K2, calcium absorbed thanks to D3 may not reach the bones efficiently. By pairing D3 with the highly bio-available MK-7 form of K2, this supplement helps maintain normal calcium balance. Each soft gel capsule delivers 2,000 IU of vitamin D3 and 50 mcg of vitamin K2 MK-7, a ratio that aligns with current research on optimal co-supplementation.

What to Look For in a D3 + K2 Supplement
When choosing a vitamin D3 and K2 supplement, consider the form and dosage of each nutrient. Micro Ingredients provides 2,000 IU of D3—a common maintenance dose—and 50 mcg of K2 MK-7, which research suggests is effective for supporting calcium metabolism. The MK-7 form is preferred due to its longer half-life, allowing once-daily dosage. Additionally, the softgels are made with coconut oil to enhance absorption. The product is non-GMO, third-party tested for purity and potency, and free from soya, dairy, and gluten. These attributes reflect a commitment to quality and transparency, making it easier to incorporate into a daily wellness routine.
Recommended Dosage and Usage
The suggested serving is one (1) soft gel capsule daily. Simply take with water and a meal. This provides 2,000 IU of vitamin D3 and 50 mcg of vitamin K2 MK-7. For most adults, this dosage supports healthy vitamin D levels and calcium balance without exceeding the tolerable upper intake levels. As with any supplement, it is wise to consult a health care professional before starting, especially if you have existing health conditions or are pregnant or nursing.
Always read the label and follow directions for uses.
Frequently Asked Questions
Can I take vitamin D3 and K2 if I am on blood thinners?
If you take anticoagulant medications like warfarin, consult your health care provider before using a vitamin K2 supplement. K2 can interfere with the action of these medications.
What is the best time of day to take these softgels?
Take one soft gel capsule daily with a meal that contains some fat, as vitamins D and K are fat-soluble. The coconut oil in the soft gel capsule helps with absorption, but taking it with food can further enhance uptake.
How long does one bottle last?
Each pouch contains 300 softgels, providing a 10-month supply at the suggested serving of one soft gel capsule per day.
