## Questions & Answers

**Q: I would like to know the source of the K2 MK-4. Is it from dairy products or from animal source like eggs, meat etc?**
A: Any and all predicts that claim to be vegan and mk4 are SYNTHETIC. Derived from geraniol extract which is synthetic. The ONLY sources for NATURAL mk4 are from ANIMAL products.

Also, please note that this product is completely FALSE in the amounts listed. Consumer labs, a totally independent testing lab found that this product contains only 13,209 mcg, or 88.1% of the claimed potency.

I'm TICKED. I've been buying this for years and feel completely ripped off by falsified claims from the manufacturer!

**Q: are these synthetic?**
A: Lots of guesswork, misinformation, and bloviating in some of the old answers to this old question.
The (probably updated) product description says "derived from orange jasmin (Murraya paniculata), leaf geraniol extract".  Sounds good, but "derived" is ambiguous.  K2 MK4 has an exact chemical formula and structure, so, other than Isomers, synthetic is exactly the same as natural. The product text also says "The MK-4 in this product is < 1% CIS Form, pharmaceutical-grade purity", so negligible isomers.  >99% Trans suggests this is of natural origin and, if not, it is still bio-identical.
No, all MK4 is NOT synthetic.  It's the animal version of K2.  Animals make it from K1 if they are eating the way they are designed to. Since most humans don't eat that way, we need to supplement. 
The always synthetic version is MK0, also known as K3 or menadione. It's not especially good for you.  It is not allowed in the USA for human supplements.

**Q: I'm sensitve to mcc.  the old formula was good.  why was it changed?**
A: This material required a filler to run on the encapsulation machinery. Because of the (groundless) witch-hunt against magnesium stearate and silicon dioxide, I reformulated to remove those materials. MCC was the alternative.

**Q: What is the source of the magnesium stearate?**
A: I think that is a question you would need to ask the manufacturer. Yet, there is another brand of K2 Menatetrenone that does not contain magnesium stearate.  It is called Complementary Prescriptions - Ultra K2 15 mg. The capsules are smaller, and it is a bit more expensive. Yet, magnesium stearate is not in it.

### ⭐⭐⭐⭐⭐ Review
*by M***C on 17 April 2025*

Recently had to get some tests due to the doctors banging their heads as to why my heart rate elevated to 128 after a vaccination and would not go down for a week. At 64 years old they ran a camera on my arm to check my veins and vessels in my heart and I am no saint. I like bacon I like butter I put cream in my coffee I eat some snacks almost every night and apparently I have the heart of a 19 year old. Very minimum calcium buildup and restrictions in my heart vessels. Been supplementing myself with this MK4 this brand this dosage that was the only dosage that was actually studied with results and true testing. Can it's action scavenge stray calcium deposits back out of your bloodstream that have built up due to the lack of the actions that are supposed to occur naturally in this modern world i do not know, I am not a scientist. But I did slip from the edge of a high seat and land right on a wood floor right straight on my butt I swear I could hear it crack and don't forget I'm 64 and x-ray could not find anything but what they think may have been maybe a hairline hairline crack that they couldn't even be sure without lots of more intensive imaging but no break of my hip on my bone on my butt on my tailbone in a couple of weeks the medium to mild throbbing in pain from landing on the bone healed right up and is gone. My bones still very rocket and strong from using the supplement at 64 years of age I can't say for sure I am not a scientist. But no serious bone fracture from a very high forefoot from the ground right straight down no feet from butt on seat the butt on wood floor crash. I have read the research papers on MK4 they are available the actual research is available. I believe in penmanship. I have never felt ready to take more than one a day of these tablets the study to dosage in research was three of these a day not this brand but this vitamin. I had originally planned starting with one make sure there's no ill effects no nausea no this know that careful steady slow watchful and careful but have continued to just take the one and like others have said every morning when I wake up no gummy plaque all around my teeth. Stop taking this for 2 days wake up with a mouthful of plaque all around your teeth.
