Over the last 20 years, research studies suggest that vitamin K2 plays a significant part in cardiovascular health – protecting against osteoporosis (K2 aids create solid bones) and also assisting minimize danger of prostate cancer. It might likewise be useful in stopping wrinkles and early aging.
The two faces of vitamin K
There are two kinds of the fat-soluble vitamin K: K1 as well as K2.
Vitamin K1, or phylloquinone, is made use of by the liver as well as plays an important duty in keeping healthy and balanced blood clot feature. Discovered largely in dark, leafy greens, leading sources of K1 consist of kale, spinach, mustard eco-friendlies, collard environment-friendlies, Swiss chard, turnip greens, parsley, broccoli, Brussels sprouts as well as romaine lettuce.
Vitamin K2 goes straight to vessel walls, bones and soft cells. Generated by grass-fed pets and also lactic acid bacteria, vitamin K2 is normally present in fermented foods such as sauerkraut, cheese and Japanese natto (soybeans fermented with bacillus subtilis, a soil microorganism) – a remarkably high source of K2 (regarding 1,103 mcg each 3-1/2 ounce offering).
An intimate connection: Vitamin K2, vitamin D and calcium
If you are supplementing with high doses of calcium as well as vitamin D – without vitamin K2 – you go to danger for calcium-related osteoporosis and arthrosclerosis.
In her book Vitamin K2 and the Calcium Paradox, Dr. Kate Rhéaume-Bleue, a naturopathic medical professional and Canadian radio as well as television health specialist, explains this phenomenon called the calcium mystery: ‘a mysterious concurrent calcium shortage (in the skeletal system) and calcium extra (in the arteries) that underlies 2 major health concerns of our time, weakening of bones and also heart condition.’
How it works: Vitamin D promotes bone health and wellness by assisting you absorb calcium. You need vitamin K2 to obtain calcium to where your body requires it as well as to stop it from being deposited in the wrong areas. K2 turns on an unique healthy protein called osteocalcin, which directs the calcium to the ‘appropriate’ locations, like your bones as well as teeth. K2 likewise activates an additional protein called matrix Gla-protein (MGP), which brushes up calcium out of the ‘wrong’ restaurants – such as soft tissues, including capillaries and also arteries – thus preventing calcification, or ‘setting’ of the arteries.
Adequate consumption of K2 guarantees solid bones and clear arteries, Rhéaume-Bleue recommends concerning 150-200 micrograms of K2 for the ‘average healthy and balanced person.’ (More K2 might be called for if you are supplementing with high dosages of vitamin D). Without enough K2 in our diet plan to trigger K2 healthy proteins, like osteocalcin as well as MGP, we are – gradually – prone to the calcium paradox, increasing our risk for weakening of bones, heart disease and also cancer.
Under study: Vitamin K2
Heart health: In the Rotterdam research, scientists in the Netherlands tracked the vitamin K consumption of topics in between 1990 and 1993 and also measured the level of cardiovascular disease and also failing (fatality from heart problem) in each subject, and how it pertaining to K2 consumption as well as arterial calcification. Scientist located calcification of the arteries to be the ideal forecaster of cardiovascular disease. Those in the highest 3rd of vitamin K2 intakes were 52 percent less most likely to develop serious calcification of the arteries, 41 percent less likely to develop heart problem, and 57 percent much less likely to die from it. Intake of vitamin K1 had no impact on cardio outcome.
Bone health: Vitamin K2 assists to trigger vitamin K-dependent proteins responsible for healthy cells and also bones. Several Japanese tests have actually revealed that K2 protected against more bone loss in postmenopausal females and, in many cases, enhanced bone mass in females with osteoporosis.
Prostate cancer: Research outcomes of the European Possible Examination right into Cancer and also Nutrition (LEGENDARY) recommend that boosted intake of vitamin K2 may reduce the danger of prostate cancer by 35 percent.
The X factor
In 1945, Dr. Weston Price, a dental professional and writer of the spots book Nutrition and also Physical Weakening, described a brand-new vitamin-like activator – which he called ‘Activator X’ – that played an important duty in the assimilation of minerals, shielding versus dental caries as well as protecting against calcification of the arteries bring about heart problem. His screening disclosed that ‘Activator X’ was existing in butterfat, the organs as well as in the fat of pets grazing on eco-friendly grass.
Activator X was later on identified as vitamin K2.
Why are grass-fed pets a crucial resource of K2? Since vitamin K1 is located in the eco-friendly tissues of swiftly growing eco-friendly plants, consisting of lawn. When animals eat yard, their cells – consisting of mammary glands (assume milk) – convert component of K1 right into vitamin K2 (though the ability to make this conversion differs among varieties).
As a fat-soluble vitamin, K2 functions synergistically as well as is most reliable when taken in with two other fat-soluble activators: vitamins An as well as D. For instance, Price found the combination of cod liver oil (high in vitamins An as well as D) and also grass-fed butter (high in vitamin K2) to be remarkable to that of taking just cod liver oil.
Best food resources of vitamin K2
According to researcher Christopher Masterjohn, the following fermented foods and also grass-fed pet or milk items include the highest quantities of vitamin K2:
- Goose liver pâté
- Hard cheeses – Gouda consists of the highest amount
- Soft cheese – Brie is a good choice
- Egg yolk (from pastured hens)
- Butter from grass-fed or pasture-raised cows (commercial butter from grain-fed cows will certainly include especially reduced degrees of K2)
- Chicken liver (ideally from free-roaming, natural hens)
- Chicken breast
- Chicken leg
- Ground beef (medium-fat)
- Calf liver
