Vitamin K deficiency as a cause of autistic symptoms

Postby Josie » Thu May 28, 2015 1:13 pm

If you have not read this paper yet, I think it has some good information on oxalic acid, Vitamin K and managing calcium.

Vitamin K deficiency as a cause of autistic symptoms

Here is a quote from page 9

The human body seems to have a reason for producing oxalic acid: to control and manage calcium. It also has the means to dispose of it once the diet contains adequate Vitamin K again: the Vitamin K triggers carboxylation of bone proteins, which can then chelate the calcium from the crystals and put the calcium where it belongs. Meanwhile the oxalic acid will be disposed of, via secretion either through the kidney tubules or across the intestinal membrane. However, if the kidney tubules are not filtering well due to the presence of CaOx crystals, or if the intestines do not contain oxalate-degrading bacteria, then the oxalic acid will remain in the body and re-crystallize. Disposal of any other waste product or toxin will be compromised also.
The Low Oxalate Diet is a poor method of addressing the problem of CaOx crystals. LOD uses dietary manipulation and citrate minerals to dissolve CaOx stones, but as the child has low Vitamin K the calcium influx is unmanaged and causes additional damage to the nervous system. The avoidance of Vitamin K1-containing vegetables means that the child’s stores of Vitamin K will be depleted and yet the liver will continue to produce oxalates.
There exists the distinct possibility that the heavy metal chelators (e.g. DMPS, DMSA, EDTA) cause dissolution of CaOx stones. The regressions and problems that children experience when undergoing heavy metal chelation are consistent with the effects from the release of uncontrolled calcium into circulation. Therefore perhaps heavy metal chelation should be halted while Vitamin K deficiencies are addressed and calcium, including the calcium bound to oxalates, is brought under control.
It is possible that the leaky gut cannot be closed until controlled calcium is brought to the tight junctions.
In conclusion, Vitamin K has a number of essential roles in the human body and it would appear its importance has been overlooked thus far. Vitamin K deficiency may be a cause of chronic neuronal hyperexcitement, which could manifest as autistic symptoms; it may also be a cause of the development of calcium oxalate crystals and stones, which may well be found in abundance in all autistic children. The administration of pharmacological doses of Vitamin K to children with autism disorders would appear to hold great promise in turning around some of the symptoms of the disease.

Vitamin K2: The Missing Nutrient

A study recently published by the European Prospective Investigation into Cancer and Nutrition (EPIC) has revealed that increased intake of vitamin K2 may reduce the risk of prostate cancer by 35 percent. The authors point out that the benefits of K2 were most pronounced for advanced prostate cancer, and, importantly, that vitamin K1 did not offer any prostate benefits.

The findings were based on data from more than 11,000 men taking part in the EPIC Heidelberg cohort. It adds to a small but fast-growing body of science supporting the potential health benefits of vitamin K2 for bone, cardiovascular, skin, brain, and now prostate health.

Unfortunately, many people are not aware of the health benefits of vitamin K2. The K vitamins have been underrated and misunderstood up until very recently in both the scientific community and the general public.

It has been commonly believed that the benefits of vitamin K are limited to its role in blood clotting. Another popular misconception is that vitamins K1 and K2 are simply different forms of the same vitamin – with the same physiological functions.

New evidence, however, has confirmed that vitamin K2’s role in the body extends far beyond blood clotting to include protecting us from heart disease, ensuring healthy skin, forming strong bones, promoting brain function, supporting growth and development and helping to prevent cancer – to name a few. In fact, vitamin K2 has so many functions not associated with vitamin K1 that many researchers insist that K1 and K2 are best seen as two different vitamins entirely.

A large epidemiological study from the Netherlands illustrates this point well. The researchers collected data on the vitamin K intakes of the subjects between 1990 and 1993 and measured the extent of heart disease in each subject, who had died from it and how this related to vitamin K2 intake and arterial calcification. They found that calcification of the arteries was the best predictor of heart disease. Those in the highest third of vitamin K2 intakes were 52 percent less likely to develop severe calcification of the arteries, 41 percent less likely to develop heart disease, and 57 percent less likely to die from it. (Geleijnse et al., 2004, pp. 3100-3105) However, intake of vitamin K1 had no effect on cardiovascular disease outcomes.

While K1 is preferentially used by the liver to activate blood clotting proteins, K2 is preferentially used by other tissues to deposit calcium in appropriate locations, such as in the bones and teeth, and prevent it from depositing in locations where it does not belong, such as the soft tissues.(Spronk et al., 2003, pp. 531-537) In an acknowledgment of the different roles played by vitamins K1 and K2, the United States Department of Agriculture (USDA) finally determined the vitamin K2 contents of foods in the U.S. diet for the first time in 2006. (Elder, Haytowitz, Howe, Peterson, & Booth, 2006, pp. 436-467)

Another common misconception is that human beings do not need vitamin K2 in their diet, since they have the capacity to convert vitamin K1 to vitamin K2. The amount of vitamin K1 in typical diets is ten times greater than that of vitamin K2, and researchers and physicians have largely dismissed the contribution of K2 to nutritional status as insignificant.

However, although animals can convert vitamin K1 to vitamin K2, a significant amount of evidence suggests that humans require preformed K2 in the diet to obtain and maintain optimal health. The strongest indication that humans require preformed vitamin K2 in the diet is that epidemiological and intervention studies both show its superiority over K1. Intake of K2 is inversely associated with heart disease in humans while intake of K1 is not (Geleijnse et al., 2004, pp. 3100-3105), and vitamin K2 is at least three times more effective than vitamin K1 at activating proteins related to skeletal metabolism. (Schurgers et al., 2007) And remember that in the study on vitamin K2’s role in treating prostate cancer, which I mentioned at the beginning of this article, vitamin K1 had no effect.

All of this evidence points to the possibility that vitamin K2 may be an essential nutrient in the human diet. So where does one find vitamin K2 in foods? The following is a list of the foods highest in vitamin K2, as measured by the USDA:

Foods high in vitamin K2
•Hard cheese
•Soft cheese
•Egg yolk
•Chicken liver
•Chicken breast
•Ground beef

Unfortunately, precise values for some foods that are likely to be high in K2 (such as organ meats) are not available at this time. The pancreas and salivary glands would be richest; reproductive organs, brains, cartilage and possibly kidneys would also be very rich; finally, bone would be richer than muscle meat. Fish eggs are also likely to be rich in K2.

It was once erroneously believed that intestinal bacteria are a major contributor to vitamin K status. However, the majority of evidence contradicts this view. Most of the vitamin K2 produced in the intestine are embedded within bacterial membranes and not available for absorption. Thus, intestinal production of K2 likely makes only a small contribution to vitamin K status. (Unden & Bongaerts, 1997, pp. 217-234)

On the other hand, fermented foods, however, such as sauerkraut, cheese and natto (a soy dish popular in Japan), contain substantial amounts of vitamin K2. Natto contains the highest concentration of K2 of any food measured; nearly all of it is present as MK-7, which research has shown to be a highly effective form. A recent study demonstrated that MK-7 increased the percentage of osteocalcin in humans three times more powerfully than did vitamin K1. (Schurgers & Vermeer, 2000, pp. 298-307)

It is important to note that commercial butter is not a significantly high source of vitamin K2. Dr. Weston A. Price, who was the first to elucidate the role of vitamin K2 in human health (though he called it “Activator X” at the time) analyzed over 20,000 samples of butter sent to him from various parts of the world. As mentioned previously in this paper, he found that the Activator X concentration varied 50-fold. Animals grazing on vitamin K-rich cereal grasses, especially wheat grass, and alfalfa in a lush green state of growth produced fat with the highest amounts of Activator X, but the soil in which the pasture was grown also influenced the quality of the butter. It was only the vitamin-rich butter grown in three feet or more of healthy top soil that had such dramatic curing properties when combined with cod liver oil in Dr. Price’s experiments and clinical practice.

Therefore, vitamin K2 levels will not be high in butter from grain-fed cows raised in confinement feedlots. Since the overwhelming majority of butter sold in the U.S. comes from such feedlots, butter is not a significant source of K2 in the diet for most people. This is yet another argument for obtaining raw butter from cows raised on green pasture.

New research which expands our understanding of the many important roles of vitamin K2 is being published at a rapid pace. Yet it is already clear that vitamin K2 is an important nutrient for human health – and one of the most poorly understood by medical authorities and the general public. ... -nutrient/

Vitamin K2 in electron transport system: are enzymes involved in vitamin K2 biosynthesis promising drug targets?

Kurosu M1, Begari E.

Author information


Aerobic and anaerobic respiratory systems allow cells to transport the electrons to terminal electron acceptors. The quinone (ubiquinone or menaquinone) pool is central to the electron transport chain. In the majority of gram-positive bacteria, vitamin K2 (menaquinone) is the sole quinone in the electron transport chain, and thus, the bacterial enzymes catalyzing the synthesis of menaquinone are potential targets for the development of novel antibacterial drugs. This manuscript reviews the role of vitamin K in bacteria and humans, and especially emphasizes on recent aspects of menaquinones in bacterial electron transport chain and on discoveries of inhibitor molecules targeting bacterial electron transport systems for new antibacterial agents.

Does menaquinone participate in brain astrocyte electron transport?

Lovern D1, Marbois B.
Author information


Quinone compounds act as membrane resident carriers of electrons between components of the electron transport chain in the periplasmic space of prokaryotes and in the mitochondria of eukaryotes. Vitamin K is a quinone compound in the human body in a storage form as menaquinone (MK); distribution includes regulated amounts in mitochondrial membranes. The human brain, which has low amounts of typical vitamin K dependent function (e.g., gamma carboxylase) has relatively high levels of MK, and different regions of brain have different amounts. Coenzyme Q (Q), is a quinone synthesized de novo, and the levels of synthesis decline with age. The levels of MK are dependent on dietary intake and generally increase with age. MK has a characterized role in the transfer of electrons to fumarate in prokaryotes. A newly recognized fumarate cycle has been identified in brain astrocytes. The MK precursor menadione has been shown to donate electrons directly to mitochondrial complex III.

Yes I am finding this interesting, the topic of k2. Recently I decided to give my apraxic daughter's sister Epsom salt baths containing magnesium. I thought this would help with her anxiety. While researching magnesium, I learned that these four things must always go together : magnesium, calcium, vitamin D3, and k2. I was quite upset to read this because I had read that children with low vitamin D at birth are more likely to develop schizophrenia as adults (I had a schizophrenic grandmother and so was trying to avoid this for my baby). I never read anything about balancing d3 though! Oh and I was breastfeeding at the same time as being pregnant, so took extra calcium in the form of a supplement. Again, I researched calcium too, but nowhere did I see that calcium supplementation can cause a magnesium deficiency. So lately I have been giving my child the magnesium Epsom salt baths and Brie cheese (which is said to have incredible levels of k2), and she has been getting good sunshine. Her speech has improved tremendously in just the past week. So, I believe this is real, k2 really does affect development, I think.

Just wanted to mention, it is not really realistic to even list Natto as a source of K2. Who is going to get their kid to eat that?

You can buy it as a vitamin supplement.

Natural Vitamin K2 (Menaquinone-7 from Natto) is the most biologically active form of vitamin K2, derived from 100% natural Japanese natto (a fermented soybean product). I give it with my son's liquid vitamin D3. I also add Pumpkin Seed Oil or Olive Oil for better absorption. It can be mixed in food or juice.

Vitamin K2 100 mcg

Build Strong Bones! Made from Menaquinone 7 (MK-7), this is the best-absorbed & non-toxic form of supplemental Vitamin K 2. Our bodies need vitamin K as a co-factor with calcium to build bone. Researchers found that people who have higher levels of vitamin K have greater bone density, while low levels of vitamin K have been found in those with osteoporosis. There is increasing evidence that vitamin K improves bone health and reduces risk of bone fractures, particularly in postmenopausal women who are at risk for osteoporosis. In addition, studies of male and female athletes have also found that vitamin K helps with bone health. Vitamin K2 is also an important nutrient for heart and arteries, supports immune health and is essential to adequate blood coagulation.

Prevent Drug-Induced Vitamin K 2 Deficiency

Medications that can lower Vitamin K2 levels in the body include*: Antibiotics (especially cephalosporins), anticonvulsants (such as phenytoin), Orlistat (Xenical, Alli) and Olestra (for weight loss), bile acid sequestrants (to lower cholesterol). ... itamin-k2/
