30.5 milligrams of Ks, 2 milligrams Astaxanthin

Excellent product, possibly the best and cheapest on amazon for getting 30 mg of K1 plus MK4 plus 0.5 mg MK7. They shipped the product the next day, very fast and it arrived very fast too. Other vitamin K products cost 10-30 times more in dollars per gram of vitamin K. Only a few products have 15-30 mg of vitamin K. :-) Vitamin K lowers the harmful calcification of the arteries, heart, brain, eyes and increases healthy calcification of bones and teeth. Those lacking vitamin K can develop high coronary artery score and die prematurely of heart disease, besides having much more osteoporosis, fractures and poor enamel and teeth health. Teeth, bones are made of calcium too, and vitamin K regulates calcium metabolism. Most vitamin K in human diet comes from greens, and the bioavailability is often 20-25 times lower than that of vitamin supplements (kale, spinach, etc). This has dramatic consequences seen in clinical studies where vitamin supplements cause huge drops in calcification markers. We can say that low vitamin K can shorten some people's lifespan by 15 years due to a premature fatal heart attack. The current RDA is very low, in Japan they use 45 mg daily for osteoporosis. MK7 has blood half-life of 4 days, MK4 and K1 about 3-6 hours. Almost all people calcify heart and arteries as they age, possibly due to low vitamin K.

This is great stuff - after discovering plugged carotid arteries and multiple TIAs/mini-strokes corrected with one side surgically I decided to use this to clean up my whole system. Six months of regular daily use with other required supplements and no more TIAs - the makers website details much information and he is quick to reply to emails. i believe this is extending my life and it is much less expensive than intensive care, surgery and recovery time. Less than a dollar a day compared to pharmaceuticals all of which have severe side effects. I think wide spread use of this along with magnesium and D3 would make a huge difference in life expectancy. I hope so and consider it a five star company. It is costly but not expensive when compared apples to apples. There is no other source of multiple high dose K2 and I recommend his website for additional information plus there ae several books specifically on K2 - None of my doctors know anything about this and all confuse it with plain K - quite frustrating and required me to do much research to get to this point. Five stars and glad to have it available.One last thing - near instant delivery in a bright red package with a bright green label - not apt to get lost. Same day shipping each time I reordered! As fast as Prime in my experience !

It has lots of K2 in it and was well recommended.

I've had lingering chest pains and consequential EKG scans for over 30 years to no avail. Doctors and specialists have diagnosed my chest pains related to stress, anxiety, etc. but were never able to find the root cause for the pain. I eat a clean, plant based vegetarian diet and don't consume any junk foods or fried foods. I recently found an article by Red Foot Associates about the importance of consuming Vitamin K. I figured I had nothing to lose so ordered their product and within a week of taking their Vitamin K, my chest pains started to subside. I contribute the MK-7 in their product to removing the calcium buildup I had in my veins which was causing the chest pains and placing it back into my bones where it belongs. I went back to their site and read all of their (lengthy) articles which I could relate to because it is written by the founder/inventor, not a physician. Is it expensive? Yes, but when you convert their serving size into what the human body needs to combat arteriosclerosis and heart disease, compared to similar Vitamin K products, the price is worth it for not having repeat visits to physicians or far worse...death!

My husband has a high calcium score and had 2 stents put in. He swears by this supplement ever since last summer. Takes his numbers down.

As prescribed by my wonderful doctor, Ward Dean, MD, I took this product for almost a year bf having my coronary artery calcium score measured. It was an amazing "0". Can't beat that. I will continue useing Koncentrated K & I put my husband on it as well. He's a believer too. I will also continue taking Serrapeptase daily as well as Mg orotate, as I have been doing for almost 20 years. I do believe that they have also helped to clean my arteries.

I do not know how effective this is, but it has rather high levels of Vitamin K2. The rice flour in the capsule causes a sugar spike, I wish they can fix this, and remove the carbs.
