True K2 Mk7 is guaranteed fully active Trans isomer. 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.

Serving size: 10 drops (500 mcg)
Servings per container: 120
Other ingredients: MCT oil.

Starting Material: Soy. - Soy free by the end of of production; determined by HPLC and Spectrographic testing. See bottom of page for a detailed explanation.
Production process: A highly complex 17 step process using 3 stages of bacterial fermentation.

What is the difference between Mk7 and Mk4?

The Mk7 fraction of vitamin K2 has a longer half life in the blood, lasting 1-3 days, compared to Mk4 which has a half life in the blood of 2-4 hours. It is believed that this longer half life accounts for its increased activity in the blood, removal and reduction of calcification of the arterial wall and more potent impact on bone and tooth calcium density.

Because Mk4 is so rapidly absorbed from circulation it is speculated that it is more active on an intracellular and neurological level.

If you can't decide which one is best for you, try our True K2 Spectrum, which has both Mk4 and Mk7.

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 (50-500 mcg 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.

Production process summary: Our Mk7 is produced through a highly complex 17 step process using 3 stages of bacterial fermentation and 4 stages of vacuum distillation. Once we are done, there is no remaining traces of soy and no signatures that would indicate soy on the spectrographic and HPLC testing that is done on completion. Quality control testing utilizing either spectrographic or HPLC is also done after each extraction and fermentation step to ensure that the refinement went as planned.
Summery: No soy remains in the final product.
