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.

    My negative feedback and BIG Disappointment

    Posted by CECCARELLI Andréas on Feb 11th 2019

    My feedback I want to express my regret and my GREAT disappointment! I have never receveid my item :.... My parcels has not been greatly and correctly delivered cause it has been lost while shipping. I wasted and lost 50 dollars. I purchased an item that I would not ever use. I will probably not be refunded... I m really confused. I really hesitate buy again on your site considering I don t have any guarantee and any trust on the reliability, tracking and safety of the shipping (anymore). By the way, I know that your items, product line is of high quality and is high valued in comparison that we can find on the market. I m really really annoyed about this situation... I want to know what you think about it? Thank you for reading and considering my issue. Kind regards your French client CECCARELLI Andréas
