I honestly don't know. Sorry that I can't be of any further help.Does this oil Vitamin K works as potent as Kuinone on the scrotum?
I used waybackmachine to dig up the detailed explanation of why your product is better (than whose?) And now your new trace mk7 form contradicts your own claims that puryifying the mk7 etc out damages the mk4? You made these interesting and important claims and then the product changed and the old page went offline because why? I dont get a good gut feeling. Cynic me thinks you lost access to old formula ans new one is inferior so you removed the page with your own words explaining why. But im willing to learn.
Wait, don't you mean trans isomer? I thought cis is the one we don't want?
Thank you for the detailed reply, in any case. I would like to know more about your sourcing and refining process without prying into private business details, if i may. Are you saying you do the extraction process now from plant to supplement? How do you confirm the quality of the finished product? The jump from mixing and bottling a manufacturer's product to now doing the refinement (and it sounds like extraction and synthesis maybe) seems like a big jump, but your background explanation of your experience is sure in support of that. You previously claimed other companies use your material for their own brand, is this true now for k2?
You being threatened to take the page down sounds terrible. Can you really be sued for making such claims? I do not recall you naming any one company.
Do you think the reason Thorne and AOR charge so much for their mk4 is because simply they can or is their own sourcing somehow so much more expensive? It sounds like your old source now has an agreement with a higher volume company only to deal with them.
Much appreciated
Such a great reply! I know natto is a rich source of mk7 but never heard it mentioned to contain mk4 before. Thorne says theirs is from Geraniol. 45g of natto supposedly contains approx 0.4-0.5mg mk7 iirc, do you know how much mk4 would be in there? I would like to be able to be accurate when I reccomend foods as sources for particular nutrients, plus I just find this fascinating.
I am looking to source products for our health store brand and my own use. I had never heard of your company before and this exchange has given me confidence in your reputability. I have some other products than k2 mk4 I want to have for retail sale as well. I am going to make an order for my own use and then contact you for further business after trying out the products on myself.
We do offer wholesale, private labeling and contract manufacturing for a variety of supplements. It is true, Natto contains mostly Mk7, but it is also the only viable source material for Mk4 for us. The other options are all animal sources. Geraniol is a terpene oil and I have never heard of it being a source of vitamin K. Is it possible you are using a wrong name for the material?
- Commentary on method for detection of menaquinone-7 in dietary supplementsIdentification of cis/trans isomers of menaquinone-7 in food as exemplified by dietary supplements.
Szterk A1, Zmysłowski A2, Bus K2.
For the first time, the cis/trans isomer content of menaquinone-7 in food products has been identified and marked. A novel method of marking isomers of vitamin K2MK-7 in dietary supplements was developed and validated. Five different isomers of cis/trans vitamin K2MK-7 were identified. Identification of cis/trans isomers was performed by HRMS-QTOF, whereas their quantities were determined by using CAD and DAD detectors. In the majority of cases, the content of biologically active all trans vitamin K2MK-7 was below its declared content. The content of all trans K2MK-7 was in the range between 5.5 and 49 µg in pills. In one of the studied supplements, this vitamin was not found, regardless of the claim on the product label. The content of cis/trans isomers in certain dietary supplements exceeded the content of all trans K2MK-7 by up to 3.7 times.

Have you considered offering your True K2 in its raw form (i.e., in no solvent)? Some may want to experiment with their own solvents or supplement blends.We do offer wholesale, private labeling and contract manufacturing for a variety of supplements.
