4.7
Made by Micro Ingredients, a supplement brand built around clean, focused formulas that are third-party tested for purity and potency. This 2-in-1 formula delivers 10,000 IU of Vitamin D3 (as Cholecalciferol) and 200 mcg of Vitamin K2 (as MK-7 Menaquinone) in a single softgel made with Virgin Coconut Oil. At this potency, this product is intended for adults who have been advised by a healthcare provider to supplement at a higher Vitamin D3 dose. Consult your healthcare provider before use. Non-GMO, gluten-free, soy-free. Third-party tested. 300 softgels per bottle, a 300-day supply at one softgel per day.
Vitamin D3 helps the body absorb calcium from the digestive tract. However, absorbed calcium needs to be directed to the right place. Without sufficient Vitamin K2, calcium can circulate in the bloodstream and deposit in soft tissues rather than going to bones and teeth where it is needed. Vitamin K2 in the MK-7 form activates proteins that direct calcium to the bone matrix and away from arterial walls. The two vitamins work together as a system: D3 improves calcium availability, K2 ensures it is used appropriately. This is why the combination is increasingly preferred over D3 alone in higher-potency supplementation.
Vitamin K2 comes in several forms. MK-4 is absorbed quickly but has a short half-life in the body, meaning it needs to be taken multiple times per day to maintain consistent levels. MK-7 has a significantly longer half-life, remaining active in the body for up to 72 hours after a single dose. This makes MK-7 more practical for once-daily supplementation and means consistent blood levels are maintained with a single daily softgel. At 200 mcg of MK-7 per softgel, this formula delivers a meaningful and well-studied dose of the preferred K2 form.
Vitamin D3 and K2 are both fat-soluble vitamins, meaning they require dietary fat to be properly absorbed. Taking fat-soluble supplements without food or a fat carrier significantly reduces their bioavailability. Micro Ingredients uses Virgin Coconut Oil as the carrier in this softgel, providing a built-in fat source that supports absorption regardless of what the person has eaten. This removes the need to plan the supplement around a specific meal and ensures consistent absorption with every dose.

01
Why is K2 included at 200 mcg?
At higher Vitamin D3 doses, more calcium is absorbed. Vitamin K2 (as MK-7) helps ensure that absorbed calcium is directed to bones and teeth rather than depositing in soft tissues. The 200 mcg MK-7 dose in this formula is calibrated to complement the 10,000 IU D3 dose. At lower D3 doses (1,000 to 5,000 IU), 100 mcg of K2 is typically sufficient. At 10,000 IU, the higher K2 amount provides additional support for calcium direction.
02
Is 10,000 IU of Vitamin D3 safe to take daily?
10,000 IU per day exceeds Health Canada's tolerable upper intake level of 4,000 IU per day for adults. Higher doses can be appropriate for people with confirmed Vitamin D deficiency or specific clinical needs, but should be taken under healthcare provider supervision with periodic monitoring of blood Vitamin D levels. Do not start supplementation at this dose without first consulting your healthcare provider and ideally confirming your baseline Vitamin D level through a blood test.
03
How is MK-7 different from MK-4?
Both are forms of Vitamin K2. MK-4 is absorbed quickly but has a very short half-life of a few hours, requiring multiple daily doses to maintain consistent blood levels. MK-7 has a half-life of up to 72 hours, meaning a single daily dose maintains consistent activity throughout the day and into the following day. MK-7 is the preferred form for once-daily supplementation and is the form used in this formula.
04
Do I need to take this with food?
Yes. D3 and K2 are fat-soluble vitamins. They require dietary fat for absorption. This formula includes Virgin Coconut Oil as a built-in fat carrier to support absorption, but taking it with a meal containing fat improves absorption further. Do not take on a completely empty stomach.
05
How long is the supply?
At one softgel per day, the 300-count bottle is a 300-day supply, approximately 10 months. This is one of the more cost-effective high-potency D3+K2 formats available.
06
Can I take this with other supplements?
D3 and K2 are generally well tolerated alongside most supplements. However, Vitamin K2 may interact with blood-thinning medications such as warfarin. If you are taking any blood-thinning medication, consult your healthcare provider before adding K2 to your routine. Also note that Vitamin A (retinol) and Vitamin D interact at high doses, so if you are taking high-dose Vitamin A supplements, discuss combined use with your provider.
