Called "Activator X" by Dr. Weston Price, Vitamin K2 is a fat soluble vitamin that supports healthy dental, bone, heart, nerve and brain health. It also supports healthy aging and energy production in the cell. K2 in the MK-7 form is largely missing in the modern diet due to the absence of traditional animal foods, especially aged cheeses. Purely K contains an optimal dose of K2 to support every tissue in the body.
- Supports bone health*
- Supports metabolism*
- Supports exercise performance*
- Supports ATP production*
- Support cardiovascular function*
- Supports brain function*

- Supports cellular signaling*
- Supports electron transport chain and oxidative phosphorylation (ATP production)
- Mitochondrial electron carrier - alternative electron acceptor/donor (complex I-III bypass)
- Protects from complex I-V inhibition
- Supplies complex III cofactors/substrates
- Protects from mitochondrial dysfunction
- Supports mitochondrial morphology
- Upregulates AMP-activated protein kinase (AMPK) signaling
One of the primary roles of Vitamin K2 is to regulate calcium and guide it out of soft tissues like arteries to bones and teeth, where it should be.
Purely K is a synergistic blend of three forms of Vitamin K:
K1 or Phylloquinone
K2 in MK-4 form called Menaquinone-4
K2 in MK-7 form called Menaquinone-7
Each one has their strengths and weaknesses. Most vitamin K supplements will contain only K2, only in the MK-7 form, or in too small of amounts to have a substantial effect on the body.
K1, or phylloquinone, activates proteins in your blood that allow clots to form. When you see the green color in plants, you're seeing phylloquinone. It acts in plants like COQ10 does in humans to allow them to produce energy. It has a similar structure to ubiquinone.
The RDA for K1 is 120 mcg for men and 90 mcg for women. We all know that the Recommended Daily Allowance (RDA) levels are set ridiculously low to support life but not robust health. One capsule of Purely K contains 500 mcg of K1.
K1 is especially important if one is on an animal-based diet and restricting vegetable consumption, which may be a good idea anyway with the rampant NPK fertilizer and tap water use. There is a very small amount in fruit but K1 is mainly present in green vegetables.
While the body can recycle K1 and dietary deficiency is rare, conditions such as intestinal malabsorption or liver disease can inhibit the recycling process. Prolonged bleeding, nose bleeds, easy bruising bleeding gums and heavy menstrual periods are all symptoms of a K1 deficiency.
Vitamin K1, sourced from evening primrose, is primarily included to support healthy blood clotting, which is useful if one is taking systemic enzymes or aspirin therapeutically. Both of those substances thin the blood so K1 from a good source is helpful to balance them.
MK-4 is the form of K2 that we naturally receive from animal foods, namely grass-fed beef, butter and pastured egg yolks. The organ meat liver contains the highest source of MK-4.
Purely K contains 1000 micrograms per serving. The amount used therapeutically in clinical studies is 4500 micrograms. If you consume a balanced diet that includes high quality animal foods, plus take two Purely K daily, it is easy to reach this number. Mammals can synthesize MK-4 from K-1.
Intake of MK-4 has shown to be neuroprotective and help reduce the risk of prostate cancer.
MK-7 is the star of the show in Purely K. Exclusively found in fermented soy, or Natto, and aged cheese, this crucial nutrient is severely deficient in the majority of the western population.
While its primary role is to activate osteocalcin and matrix GLA protein to regulate calcium throughout your body, its benefits extend far beyond that. Dramatically reducing your risk for arthritis, osteoporosis and atherosclerosis is just the beginning!
K2 MK-7 has been shown to prevent and reverse arterial blockages, prevent heart attacks, increase bone density, prevent diabetes, reduce insulin production, reduce the risk of Alzheimer's disease, prevent wrinkles, prevent varicose veins, and even increase energy production in the cells.
Vitamin K1 and K2 MK-4 has a shorter half life than K2 MK-7, meaning that with K2 MK-7, taking it on a regular basis will yield the best results.
WHY NO VITAMIN D WITH IT?!
This issue is the main reason why this product was created!
Supplementing Vitamin (hormone) D can cause more problems and counteract or negate the benefits you're getting from your K2 supplement. This is because vitamins, minerals and amino acids are all on a see-saw. Take one and you deplete or decrease the absorption of another.
As you can see, vitamin D antagonizes vitamin A and B3, two vitamins that are already low in many people. Vitamin D also increases your requirement for Vitamin K2.
While hormone D increases the benefits that you get from K2 activated proteins, it is playing with fire to supplement it. Taking vitamin D in a magnesium-deficient state (everyone) will increase calcification. You can't take enough K2 to keep up with the calcification! It is a vicious circle.
The solution is to get your Vitamin D from light, either sunlight if the UV index is high enough where you live, or from a light device if you live far away from the equator. It is much safer to get it from ultraviolet light than it is from a supplement.
The optimal dose is at least two capsules daily, either together or split up with a meal. Note: Consider the suggested dose on the bottle a typo! Vitamin K2 MK-7 is very safe to supplement as supported by the clinical research.
The median lethal dose (LD50) is north of 2000 mg per kg of bodyweight. That is 2,000,000 micrograms (mcg) per kilogram! This means that a person that weighs 150 lb would have to take 136,363,636 micrograms or 681,818 capsules of Purely K in one day to get up to a dangerous dose! You'd go broke first! Don't sweat and take your Purely K!

I don't feel any different and there is really no way to know if this supplement is doing anything. However, the label indicates that is has the best combination of the forms of Vitamin K, so I will keep taking it.
After a few weeks of taking vitamin K2 I noticed a huge difference with my cycle, instead of 7 days two of those heavy my period changed to 4 days! It has always been 7 for as long as I can remember. Vitamin K2 is the only thing I’ve added to my supplements I take daily (shilajit, magnesium bicarbonate,vit. E, B power, whole food vit. C & boron) I’m nursing a 16 month old and my teeth seem good too. I love all mitolife supplements they are spendy but they work unlike others I’ve tried.
Keep up these amazing supplements!
Is amazing.. I ran out of it so I can’t wait to stock up on more next time it’s in stock.. Truly feel way better giving my body one of the most important vitamins/minerals. K is very important and I never knew that before coming across Matt’s instagrams. Learning a lot. Thanks Matt and mitolife. I will continue this healing journey with the help of you’re natural products
Love this stuff! My teeth sensitivity has gone way down since I started taking these. I can’t wait to see what my dentist says next month. Along with raw cheeses and milk, I also split a capsule between my two little sons. Vit K is crucial at this developing time in their lives.
Great Product! Definitely noticed a difference in my teeth and nails!
