Koncentrated K features high therapeutic doses of Vitamin K1, Vitamins MK4 and MK7 and Astaxanthin, a powerful antioxidant, and is the only brand that offers these ingredients.  Koncentrated K is significantly lower priced than other brands.

How does Koncentrated K support health?
Koncentrated K provides more vitamin Ks than you could ever eat in a day...with their health benefits supported by scads of scientific research.

Scientific studies show that K1, MK7 and MK4 are important for heart health, bone health, have anti-cancer properties, and appear to be anti-aging.  Research shows most people are deficient in vitamin K and taking Koncentrated K ensures you have enough for the health needs of your body.

Vitamin K is non-toxic and there are no upper limits to how much you take, making our high dosage Koncentrated K a great value.  To read more view the Supplement Facts tab below…

Koncentrated K a Brief Overview:

The Koncentrated K capsule has 25 mg of MK-4, 0.5 mg of MK-7, 5 mg of K1 and 2 mg of Astaxanthin.

Why this combination?  We chose one pill to do it all because the K vitamins are a “team” in the body, especially when it is recognized that the A to D to K ratio (developed and championed by the author) is critical to sustain in your body for 24 hrs per day.  All K vitamins are similar in structure, but differ in the length of the “side chain”.  The longer the side chain, the better effect and efficiency.  Consequently, the long chain menaquinones, especially MK-7, are important as they are nearly completely absorbed and stay in the blood for the longest time, and then remain available for tissues outside the liver, namely bones, arteries and soft tissues (organs).  Research has also found that Mk7, Mk4 and K1 show up in different tissues within the body, making it important that the Koncentrated K capsule offers the most important K vitamins that research has substantiated as vital to body functioning.  When food derived from different forms of phylloquinone and menaquinones were ingested in equal microgram quantities, menaquinones were found to have a concentration 10 times higher than the phylloquinone (Schurgers & Vermeer, 2000).  Research also shows that MK-7 has a dramatically longer half-life relative to vitamin K1, so the Koncentrated K supplement provides a more stable bioavailability of K in your body over a 24 to 72 hour period  (Schurgers et al., 2007).

Here is what the four natural chemicals look like and as you can easily see, they are in an odd way similar.

 Keep it simple  - - - (the kiss principle hard at work)!!!!!!!!

Lets keep K1 simple:  K1 (phylloquinone) is involved in clotting and bone formation.  Basically that is its job.  It has “backup” duties, but clotting is #1.

Lets keep Astaxanthin simple:  this is a natural product and is the pink in pink salmon, or the pink in rainbow trout, or the pink in pink flamingos.  It is also fat soluble, with a chemical structure similar to K.  Astaxanthin is carried on your neutraphils and leukocytes, which are both types of white blood cells.  Astaxanthin, inhibits the production of MMP-2 and MMP-9 which are chemicals produced by those white blood cells and which tend to induce heart disease (they are chemical irritants to an artery).  Thus, Astaxanthin is a potent antioxidant and opponent to those elements which promote atherosclerosis.  And Astaxanthin is far superior to C as an antioxidant per the literature.  (When one looks at vitamin C, this natural chemical appears to be primarily a virus and bacteria “killer” when taken in sufficient amounts, approximately 6 to 20 grams per day).

Lets keep MK-7 simple:  MK-7 is involved with many of the same things as K1 and MK-4 but is unique in that MK-7 “hangs around” your system for 48 to 72 hrs.  Why?   Most likely to cover for the depletion of K1 and MK-4.   A good way to look at MK-7 is that it is the backup to K1 and MK-4,  kind of a ready reserve of “K” just in case the others are depleted.  The body is just amazing as to the backup systems in place.

Lets keep MK-4 simple:  MK-4 is the plough horse of the K vitamins.  This chemical is quickly processed and distributed.  Why?  Most likely because the body is in constant demand for this natural and friendly chemical.  So, what are the implications for this plough horse?  Research from Canada implicates MK-4 in the prevention of Alzheimer’s.  Research from Japan implicates MK-4 as a preventer and reverser of Osteoporosis.  Other research indicated the potential for MK-4 to stop, reverse, and then prevent atherosclerosis.  MK-4 coupled with Vitamin D and Magnesium, are in theory, a potent “cocktail” that speeds bone healing.  Additionally, MK4 is implicated in kidney stone prevention - just to name a few possibilities.  The advances in vitamin K analysis of tissues in the body have implicated MK-4 as having particular physiological importance.  This vitamer (aka, a natural chemical) is not synthesized in significant amounts by bacteria in the gut and its concentration in nutrients is relatively low.  Nonetheless, MK-4 is abundant in tissues such as brain, pancreas, salivary glands, kidney and sternum.  (Thijssen and Drittij-Reijnders, 1994: Davidson et al.  1998: Thijssen et al.  1996).  This MK-4 tissue distribution is quite distinct from that of the chemically similar vitamins such as phylloquinone (K1).  (For example, in rats the tissue concentration ratios of phylloquinone to MK-4 vary from 24:1 in the liver to 0.1:1 in the brain.  (Davidson et al, 1998).

So, there you have it.  The simple “why” behind Koncentrated K.  We encourage you to read the literature contained in this site so as to “get up to speed” with regard to K and how it may impact your life in a positive mode.  Again, each component has a role to play and basically they are good and good for you.
