    Production process: A highly complex 17 step process using 3 stages of bacterial fermentation.
  • Mk4 Starting Material: K2(20) side chain natural, from Geraniol.
    Production process: A highly complex 23 step process using 4 stages of bacterial fermentation. 

K2-Mk4 Properties and Benefits:

  • Easily Absorbed.
  • Rapidly distributes through the body in 2-4 hours.
  • Has a very short half life in the blood. Only 2-4 hours.
  • Most abundant form in the body.
  • Frequent dosing (2-3 times per day) required for best results.
  • Works best at doses above 10mg per day.
  • The only form active in the nervous system.
  • Helps regulate nerve cell membrane structure through vitamin K dependent proteins.
  • Helps regulate nerve inflammatory response, particularly in the brain.
  • Reduces oxidative stress in the nervous system.
  • MK-4 crosses the placental barrier and may be important in neurological, bone and dental development of the fetus.
  • Human breast milk only contains Mk-4.
  • The most scientifically studied for bone health.

 K2-Mk7 Properties and Benefits:

  • Absorbs faster than Mk4.
  • The body can convert Mk7 into Mk4, Mk8, Mk9 and Mk10.
  • Studies have shown that Mk7 supplementation is more effective than Mk4 supplementation at increasing liver Mk4 levels.
  • Fourth most abundant form in the body.
  • Most abundant form in the blood.
  • Has a long half life in the blood of 2-3 days.
  • Low doses (50-500mcg per day) needed to see benefits.
  • Mk7 more effectively activates the carboxylation of osteocalcin and does so in a more stable way.
  • Studies suggest Mk7 may be more effective than Mk4 for bone density and the maintenance of blood calcium.
  • Studies suggest Mk7 may have a more significant impact on reversing arterial sclerosis and arterial stiffness than Mk4. 

It took me 4 years of research, searching and rejected samples that didn't pass testing to find this beautiful vitamin K2. I thought finding a K2 would be simple to source, but I was astounded at the shear volume of low quality vitamin K2 on the market to the point I'm convinced this is a systemic problem. Over 90% of the samples tested did not contain any Trans isomer or had significantly less Trans isomer than stated by the manufacturer. The only raw material we accept is 98% or higher in Trans isomer. The second problem common in the industry is stability, or the degradation of the Trans isomer over time. Over 60% of the retail K2 supplements tested had degraded below 50% of the stated label value less than a year after manufacture. So even if the starting K2 concentrate is of high quality, how it is handled during the manufacturing process is VERY important. Through our own research we have developed a strict production process that delivers a guaranteed yield of Trans isomer vitamin K2, up to 3 years from the date of manufacture.

Care and Storage:
Use within 1 year of opening.
After opening, keep tightly sealed and store at room temperature in a dry location away from light.
Do not refrigerate after opening; doing so will increase the uptake of moisture and spoil this product. This product may be refrigerated if the original manufacturer's seal has not been broken.

    HN is Superb Company!

    Posted by terry on May 22nd 2023

    I'm an old fart and been taking supplements for a long time. It's my belief that Health Natura is probably the best company I've ever dealt with. If all companies were trying to present the best products possible and had as much integrity as HN it would be a much better supplement world.

    Best K2 (Mk4/Mk7)

    Posted by Marie Stumphauzer, FNTP on May 13th 2023

    Outstanding product, well made. I love to rub a bit on my gums several nights a week before bed. My oral health is exceptional, thanks in part to this practice. This is also a great way to balance aspirin use (I get my aspirin powder from HealthNatura, too!).

    Great product

    Posted by Helen on Dec 26th 2022

    I give this to my 3 year old to get k2 in his diet. Love that it’s liquid based! I tell him it’s our strong vitamin and he usually takes it. Wonderful product.

    Really Works!

    Posted by Gayle on May 18th 2022

    I had been using another highly recommended brand of Vitamin K for two years but did not notice much of a difference in my spider veins. Since using this product there has been a substantial reduction in the veins. Plus I love that this is liquid and can add to my other liquid supplements in one glass of water as I don't like taking capsules. Thank you Health Natura!
