Vitamin K1 Vs K: What You Should Know

Why Vitamin K2 is so important (and how to get it)

Vitamin K is well known for its role in blood clotting, but supplements containing vitamin K are growing in popularity for other uses. Some people, especially older women, are taking vitamin K as a supplement to improve bone strength and reduce fractures. While there is evidence to support this use, itâs important to help patients pick the right supplement to ensure they are taking the right form of vitamin K.

Vitamin K1 and vitamin K2 are available in North America as supplements. Vitamin K1 is the most common form of vitamin K found in the diet, so the recommended daily intake for vitamin K is based mainly on vitamin K1. Most people following a Western diet can easily achieve the RDI for vitamin K by eating leafy greens like kale and spinach. A cup of raw spinach contains 145 mcg of vitamin K, which is more than 180% the daily value.

Vitamin K2 intake, on the other hand, is generally lower in the Western diet. For instance, a 3-ounce serving of chicken breast or ground beef contains vitamin K2, but only in amounts ranging from 6-13 mcg. Recently, it has been suggested that K1 and K2 be split into separate RDIs to ensure adequate intake of both. This might be important because vitamin K2 is distributed throughout the body, whereas vitamin K1 is absorbed by the liver. And vitamin K2 appears to be most promising for some of the more popular uses, including bone health.

More Leafy Greens High In Vitamin K

  • 740% DV in 1 cup of cooked spinach
  • 644% DV in 1 cup of cooked collards
  • 581% DV in 1 cup of cooked beet greens
  • 441% DV in 1 cup of cooked turnip greens

Note: Cooking only concentrates the vitamin K in these greens. The raw uncooked forms are also high in vitamin K.

  • 55% DV in 1 cup of kimchi
  • 15% DV in 1 cup of sauerkraut

Should You Take A Vitamin K Supplement

Vitamin K1 is found widely in foods. If you are eating enough food and especially if your diet includes a decent amount of leafy vegetables you will almost certainly get more than you need. But vitamin K2 is a bit more tricky. Some people are able to convert vitamin K1 to vitamin K2. But not everyone has the ability to. And since the main sources of vitamin K2 in the modern diet are certain fermented soy products, and animal products , many people, and especially vegans, may want to consider a supplement.

A word of caution: People who are taking anticoagulant medications need to consciously maintain a consistent and specific intake of vitamin K from food and supplements. Sudden changes in how much vitamin K theyre getting can impact the anticoagulant effect of their medication, either amplifying or reducing its activity.

Bronson Vitamin K Triple Play is another take on the triple-sourced vitamin K combination. This isnt the highest dose version on the market, but youll still get 550 mcg of vitamin K all together.

The capsules are gelatin-based, which wont please strict vegetarians and vegans, but the bigger issue is the presence of fillers and additives that you wont find in some other competitors. Its not a dealbreaker the vitamin K content is still good enough to make up for it.

Vitamin K Guidelines For Warfarin

11 Amazing Health Benefits of Vitamin K
  • A PT measures how quickly your blood clots. For people taking blood thinners, the results are expressed as a ratio called INR
  • A low INR means you have increased risk of clotting
  • A high INR means you have an increased risk of bleeding
  • Warfarin increases INR, Vitamin K decreases it
  • Most doctors aim to keep INR around 2-3, but can range to 2.5-3.5 for heart valves or other extreme cases
  • Regularly check your PT/INR levels
  • Take the same amount of Warfarin at the same time each day
  • Keep your intake of vitamin K consistent from day to day because when a doctor prescribes Warfarin, they are trying to balance it with how much vitamin K you habitually eat

Vitamin K-dependent proteins that require the intake of vitamin K to function properly dont just affect your bone modeling, though.

The VKDPs not associated with bone growth or blood clotting are involved with the metabolism of sphingolipids, a class of lipids commonly found in brain cell membranes that are involved with cellular events.

Changes in sphingolipid metabolism have been linked with not only age-related cognitive decline but also neurodegenerative conditions like Alzheimers .

Recent research suggests that vitamin K antagonists, which are used as anticoagulants, may have a negative effect on visual memory, verbal fluency, and brain volume. But it doesnt appear to go in just one direction .

Higher vitamin K levels, specifically phylloquinone , are associated with improved verbal episodic memory, though no difference was observed with non-verbal episodic memory .

Who Should Take A Vitamin K Supplement

Newborn babies are at risk of being deficient in vitamin K due to the poor transport through the placenta. This risk is increased in infants exclusively breastfed as breast milk is a poor source of this vitamin. As low vitamin K levels can cause vitamin K deficiency bleeding , its recommended that newborns are given 0.5 to 1 mg of vitamin K1 at birth.

Another group likely to develop a vitamin K deficiency includes people with malabsorption disorders. Those who may have problems with vitamin K absorption are people with:

Helps With Blood Coagulation

This may be the most well-known role of vitamin K in your body. Remember, vitamin K was named after the German word koagulation. Both vitamins K1 and K2 are involved in blood clotting, which is what keeps you from bleeding to death when you get a cut. Specifically, vitamin K is needed to manage proteins involved in the blood clotting process. If you dont get enough vitamin K, you are more likely to experience hemorrhaging, or excessive bleeding, from a wound.

How You Cook Counts

How to Get Enough k2 on a Plant Based Diet

The amount of vitamin K you get from foods depends on how you prepare it. Frozen foods — that you cook — often have more than raw forms. This is probably because frozen vegetables lose some of their water, which concentrates the vitamins. For example, a half cup of boiled frozen turnip greens nets you more than 425 micrograms. But eating raw turnip greens gives much less than that.

The Abcs Of Vitamin K1 K2 And K3

Researchers have identified three main forms of vitamin K: Vitamin K1, vitamin K2, and vitamin K3. Furthermore, there are two principal forms of vitamin K2. Each has slight differences in chemical structure, but all seem to be used by the body. Vitamin K3 is not used in supplements for people, so the important forms are vitamins K1 and K2.

Vitamin K1. Known also as phylloquinone, Vitamin K1 is naturally found in leafy green vegetables, such as dark lettuce varieties, spinach, kale, and broccoli. It promotes normal blood coagulation and bone strength.1 Its available as a supplement, but does not appear to be as potent as vitamin K2.

Vitamin K2 occurs in several forms, but two appear to have the most biological activity: MK-4 and MK-7 . Both forms seem to have advantages, but in different ways.

The MK-4 form of vitamin K is naturally found in egg yolk, egg mayonnaise, chicken thighs, and dairy products. Substantial research shows that very high supplemental doses of the MK-4 form of vitamin K2 can prevent and reverse osteoporosis. The MK-7 form of vitamin K is naturally found in natto, a type of fermented soybean food. One ounce of natto provides about 250 mcg of MK-7.1 The MK-7 form of vitamin K2 is absorbed much better than vitamin K1. Its unclear at this point whether MK-7 is absorbed better than MK-4, but the MK-7 form does seem to stay in the blood longer.

Meat Eggs And Dairy From Grass

These animal products must come from grass-fed and pastured raised animals. Dont trust marketers who use words like cage-free or organic as that doesnt necessarily mean the animals got the necessary life to give you proper nutrition. Your best option, if possible, is to find local farms where you can actually see and discuss their farming practices.

Even supplementing can be tricky as the specific type of vitamin K2 found in grass-fed animal products is very expensive to replicate and synthetic MK-4 is all youll be able to find. Because the synthetic form is metabolized quickly youll have to take several doses to keep your K2 levels in range.

This is why my family always tries to get our nourishment from whole foods. The body just knows what to do with it better plus, Im guessing there are even more complex things happening in our food than our scientists know. Mother nature has been doing this whole nourishing thing for a lot longer than any lab. Some whole food options include: making your own raw butter or indulging in beautiful golden grass-fed ghee.

Vitamin K: Benefits, Side Effects &  Dosage

Vitamin K isnt likely to cause toxicity.

Theres no known toxicity for vitamin K1 or K2 from food or supplements. Thats why theres no established tolerable upper intake level set for it.

Q: I Heard That The Vitamin K Shot Might Cause Cancer Is This True

A: No. In the early 1990s, a small study in England found an association between the vitamin K shot and childhood cancer. An association means that two things are happening at the same time in the same person, but doesnt tell us whether one causes the other. Figuring out whether vitamin K might cause childhood cancer was very important because every newborn is expected to get a vitamin K shot. If vitamin K was causing cancer, we would expect to see the same association in other groups of children. Scientists looked to see if they could find the same association in other children, but this association between vitamin K and childhood cancer was never found again in any other study.
