NutriStart Naturally NutriStart Naturally - Quick K2 120 mcg, 50 ml
NutriStart Naturally Quick K2 - Vitamin K develops bones during growth by directing calcium where to go in the skeleton and in the cells. Vitamin K2 is not only necessary for growing bones but will rebuild and maintain bones in adults as well, and is one of the most important nutrients required to prevent osteoporosis.

Why people keep reordering it
- D3 paired with K2
- The combination that helps steer calcium toward your bones.
- Built for Canadian winters
- Tops up the vitamin D most of us run low on from October to April.
- Bone and immune support
- Foundational for immune function and long-term bone strength.
Best suited to: anyone taking 2000 iu or more of vitamin d, people on a daily calcium supplement, someone who wants k2 without a fixed d3 dose attached, anyone who never eats natto.
What the research supports
Six drops give 120 mcg of K2 as MK-7 in sunflower oil. There's nothing else in the bottle.
Bone density trials use 180 mcg of MK-7 a day.
- Bone density (evidence: moderate, from randomized controlled trial)
- MK-7 attaches to two proteins that decide where calcium in the blood ends up, sending it toward bone. Three years of 180 mcg a day slowed bone density loss in postmenopausal women.
- Arterial calcium (evidence: limited, from randomized controlled trial, mechanistic study)
- MK-7 also activates a protein outside the skeleton that keeps calcium out of soft tissue like blood vessel walls. Human data at these doses is still limited to blood markers.

Is it right for you
Worth it if
- Anyone taking 2000 IU or more of vitamin D
- More D means more calcium absorbed, and K2 is the step that activates the proteins deciding where that calcium lands.
- People on a daily calcium supplement
- 120 mcg of MK-7 is a real dose of the nutrient that carboxylates osteocalcin, which is what actually binds calcium into the bone matrix.
- Someone who wants K2 without a fixed D3 dose attached
- This is menaquinone-7 alone, so you set your vitamin D separately instead of having the two locked to a ratio.
- Anyone who never eats natto
- Fermented soy is the only concentrated dietary source of long chain menaquinones, and a typical Western diet supplies well under 20 mcg a day.
Look elsewhere if
- Someone whose vitamin D is low
- Fix D3 first at 1000 to 2000 IU daily. K2 directs calcium, but D3 is what gets calcium absorbed in the first place, and K2 alone has little to work with.
- Anyone whose vitamin K intake needs to stay constant
- Talk to a practitioner before starting if you take something every day, and once started do not add and drop it week to week.
- Someone shopping for a complete bone formula
- A combined product carrying calcium, magnesium, D3 and K2 covers the full set. This is one nutrient at one dose.
What to expect
Nothing you can feel, at any point. Undercarboxylated osteocalcin in blood falls within about four weeks of daily MK-7, and the bone density work was measured in years, not months.
How it compares
- Compared with vitamin K2 as MK-4
- MK-7's half life is measured in days rather than hours, so 120 mcg once a day keeps blood levels steady where MK-4 needs 45 mg split across the day to do the same job. The tradeoff: MK-4 has its own Japanese fracture data at that 45 mg dose and costs less per milligram. MK-7's long half life also means it lingers, so it is slower to clear if you need to stop.
