5.0 out of 5 stars K2 is scientifically proven to transport away Calcium from Arteries by activating Matrix GLA Protein
From my research;K2 complexes (K4-10) are produced by the bacteria in your gut, and are also contained in the right typesof mainly fermented fatty dairy (as its a fat soluble vitamin) like cheese, whole yogurt, fermented vegetables, such as sauerkraut, and beans. Its fermented beans that produce the most K2-MK7. But the human form we, and all animals produce is K2-MK4. MK4 is utilized instantly and probably activates more functions than MK7 (which has a long half life). Nevertheless MK7 is proven to have biological effect.Its estimated you need about 50-100μg of K2 per day.Antibiotics can wipe gut production of K2 out as it wipes out your gut bacteria.The major source of K2 intake is estimated to be from fermented foods.Typically something like harder Edam cheese contains upto 10μg/100g of K2mk7. But softer semi crumbly cheeses like Cheshire tend to be higher (upto 29.1 μg/100 g). There are a range of K2 subtypes (MK4-10). MK4 is what is produced by all animals, other types by bacteria. Fermented Dairy is higher in MK8-10 rather than MK4-7. MK10 is higher in very hard cheese. Because of the various fermentation methods there is a spectrum of K2 types in cheeses. For example Jarlsberg has 62 μg/100g of K2-MK9. Non fermented dairy foods (eg; Eggs, Milk) contain - eg; Eggs vary and contain about 7-20μg/100g. Milk has 2μg/100g. Kefir/Yogurt, seem to be about 10μg/100 g.But it's fermented Beans, contains the most astonishing amounts of K2 - upto 1000 μg/100 g - in natto. About 5μg/100g in sauerkraut. Both of type K2-MK7.But whats the big deal? Cardiovascular disease (calcified arterial plaque) is the main cause of death. K2 prevents the the calcification of arteries by activating proteins in the bloodstream, which then collect calcium. These are called Matrix GLA proteins.=======================There is scientific evidence from rat studies (the rat warfarin K2-mk7 study) that it can reverse calcification of arteries.The study of this vitamin is very recent and is just starting, so the scientific studies are sparce, but there is overwhelming evidence that it prevents calcification of arteries in patients with chronic kidney disease, which is a major problem for them, or patients on warfarin (a drug which destroys K2 and thus calcification of arteries is common).But the effect of K2 is limited by how much matrix protein and other calcium (Ca+) loving proteins there are available to be activated by K2 in your blood. So taking 600μg of K2-MK7 when your body only has a pool of proteins for 100μg is not going to give you 6 times the effect.The pool of these proteins available to be activated is increased by taking vitamin D3 - and also by exercise.However, with heart disease and atherosclerosis, it is not calcification which kills, it is the sudden blood clots which kill - blood coming into contact with EXPOSED soft plaque. NOT the calcification itself, which is a repeated healing 'scar tissue' process which forms a hard plaque cap over dangerous soft plaques (although it also narrows and stiffens the artery).Based on the above I would NOT do mega doses of both D3 (which ramps up the amount of Ca+ loving proteins for K2 to activate) and K2 to decalcify arteries, but would instead keep it in the normal range of 100-200μg Vitamin K2 and 1000-2000IU Vitamin D (25-50μg) daily. The D3->increased Ca+ collecting Proteins + K2 activation will be within normal limits, a process which should normally go on within a healthy body with the right amount of sunlight and diet so there should be no adverse effects of arterial decalcification exposing soft plaque staying in these limits.The Rotterdam K2 study (about 4800 people, age over 55 - based on self reported diet-sheets, medical followups) , seemed to show a substantial drop in heart disease event risk, in those with higher K2(MK4,8,9 from eggs and cheese) intake. The population subset that had over 40μg of K2 daily had about half the heart attacks. Further, aortic calcification (from chest xrays at 2 angles) were logged and the over 33μg K2 intake group again had half the rate of severe aortic calcification. (no effect on moderate aortic calcification).*** UPDATE: I now have bought an electric pressure cooker to make actual natto (an instantpot, but many others will do as long as they have a yogurt setting), and bought bags of 'natto starter' (you can get this easily and very cheaply online).I now make large batches of natto with beans (any tinned drained beans, even chickpeas will do fine) it takes only a few minutes to setup and its ready the next day, lasts a week in the fridge and costs next to nothing. A single tablespoon of natto beans will give 300μg of K2-MK7 - easier than taking a tablet!I like the 'coffee' taste of the natto beans, but you are best using seasoning like soy or mustard etc... to add more complexity to the flavor when enjoying a proper bowl.
5.0 out of 5 stars No side effects, easy to swallow, improved vasodilation?
Swallowing:First of all, the pills arent too big, and still some people might have trouble swallowing them. I opened one pill (easy to do) and poured the contents into water to find whether it mixes. It mixed really quick and well. The flavour of the water was not altered. So if you have trouble with big pills you can easily do this.Secondly, I have heard of people experiencing heart palpitations from K2, particularly from K2-7 because of its longer half-life. This is speculated to be because K2 causes hypocalcemia by taking serum calcium and depositing it into bone tissue. I have been using for a week (1 per day) and have had no issues. This K2-7 is high dose so I am taking 500-1000mg of magnesium glycinate daily and 50 000 iu of D3 to make sure the calcium levels and calcium to magnesium ratio are maintained. I am also taking 45-60 mg (not mcg) of K2-4 per day.As a rule of thumb K2, D3 (at least 4 000 iu /day) and magnesium citrate/glicanate/oxide or any other form should be taken together as they are incredibly synergistic.I have always had an issue where I'd get lightheaded (almost passing out) <from low blood pressure> when I stand up after ive been in a squatting/sitting/lying position for a while. Now, blood pressure is regulated by your blood vessels expanding and constricting, but if they are damaged (e.g. calcified or plaqued) this function of theirs would be impaired. My D3 was 104 nmol/l before I started this protocol (so it wasn't anything that would be considered low.Today I noticed that I haven't experienced that lightheadedness in 2-3 days. I will keep an eye on it consciously over the next couple of days and see how it is. I wasn't aiming to fix that problem but if it does get resolved that's wonderful. (I'm 20).Another thing - my digestion and joint pain/stiffness seems to be much better but it could be caused by something else so I will wait before I comment further on that.I will most likely update in a few weeks.If you found this helpful, please click the 'helpful' button below so others can see it too!

4.0 out of 5 stars Very good value
The dosage of each capsule is very high, perhaps undesirably so. Only100 to 200 micro grams daily is needed; however, this means that a third or sixth of a capsule daily, or, as vitamin K is fat solluable, one full capsule evey 3 or 6 days is fine. This makes them outstandingly good value and vety cheap. I will buy again.If you are thinking about taking a full capsule evey day, do research it first.
5.0 out of 5 stars Review
Great products
5.0 out of 5 stars The high dose of a single capsule is a good thimg.
I am experimenting with dosage.. and think the high dose in this single cap' is better than taking handfuls at a time of smaller dose capsules..So far I have felt no adverse effects at all from taking two or three cap's daily.. and may increase this to four cap's or more in time.I haven't read of anyone having any bad side effects (yet..) from K2.. and so feel that my agressive aim to reduce my calcium score is going well.. and safely.I'm satisfied now that the K2 really is helping to reduce the knee pain I have had for a long time, along with shoulder pain.. which is great.For about seven months I haven't been able to stand up on my hind legs.. the pain in my knees was unbearable.To cut a long story short, I can now at least stand up, with far less pain... and the knees can bear my full weight.. this is a big deal to me.I was pretty sure that these joint pains were caused by excess calcium deposits.. and this seems to confirm my thougjhts.But my major concern is my overall 'calcium score'..I am very pleased with these K2 capsules and can happilly reccomend them, and this company, to others.They arrived promptly, were very well packaged.. and I have no complaints.I will definitely be re-ordering shortly.
Works well, trying new smaller size.
I have been pleased with this product, I have been using it for 2 over years. It's the highest potency I've been able to find for a reasonable price. I was a little concerned when I opened the bottle to find the pills were half the size so I emailed their support. They responded almost immediately last night at midnight. They said they want to assure me the quality remains excellent, the difference in size was carefully implemented as they have upgraded to a more potent form of Vitamin K2. Part of their goal was to make the pills easier to swallow as well as improving their efficacy. I will update if I notice anything different.
