Highest Vitamin K Foods and Recipes: A Practical Guide

Vitamin K is a fat-soluble vitamin that exists in its vitamin K1 and K2 forms.  Although both forms of vitamin K have different functions and are found in various foods, they have similar structures and some similar roles.

Vitamin K1 (phylloquinone) is an essential fat-soluble nutrient that makes up around 75-90% of all vitamin K consumed by humans.  It is mainly found in green and leafy vegetables.  

On the other hand, K2 (menaquinone) makes up the remaining 10 – 25% of vitamin K consumed by humans and can be found in fermented foods and animal products.  Vitamin K2 is also made up of several subtypes of its own.

What Does Vitamin K Do in Your Body?

Vitamin K1 is said to have a lower absorption rate than vitamin K2, with estimates as low as 10% of the vitamin being absorbed.  This could be because K2 foods are often rich in fat, whereas K1 sources are often leafy green vegetables.  For best results, put some butter on that kale!

Vitamin K1 vs Vitamin K2

It’s important to note that K1 (phylloquinone) is found in plant foods, while K2 (menaquinone) is found in animal and fermented foods.  Vitamin K2 is thought to be more critical for factors other than blood clotting. 

Unfortunately, only Vitamin K1 is quantified in the various nutritional databases, so it’s hard to know if you’re getting sufficient K2 using Cronometer.  However, Chris Masterjohn recommends getting 100 to 200 micrograms of K2 per day and has compiled The Ultimate Vitamin K2 Resource to help you determine if you are getting enough.

People on a strict vegan diet will get plenty of K1 but less K2.  On the contrary, people on a carnivorous diet may get K2 and little K1.  Although the conversion factor varies, most people can convert adequate K1 to K2.  It’s not as clear if we can convert K2 to K1. 

Vitamin K Foods

Although vitamins K1 and K2 look similar, they are found in different foods for the most part.  For this reason, we’ve provided a vitamin K foods list to see foods that contain vitamin K1 and vitamin K2.

Vitamin K1 Foods

Some of the more popular foods that contain higher levels of vitamin K1 include:

  • parsley
  • kale 
  • spinach 
  • coriander (cilantro)
  • mixed greens
  • lettuce
  • cabbage
  • broccoli 
  • Brussels sprouts
  • broccoli sprouts
  • asparagus 
  • celery 
  • dill pickles
  • sour pickles
  • green beans 
  • cucumber
  • sauerkraut
  • kiwifruit
  • black pepper
  • cauliflower
  • blackberries 
  • carrots
  • green peppers

Plants readily produce vitamin K1.  Subsequently, fresh fruits and vegetables are the best sources of vitamin K1. 

See top foods high in vitamin K1 on Nutrient Optimiser for more detail.  

Vitamin K2 Foods

Foods that are rich in vitamin K2 include:

  • cheese
  • yogurt
  • kefir
  • other dairy products
  • natto
  • sauerkraut
  • kimchi
  • eel
  • liver
  • egg yolks
  • beef
  • chicken
  • pork
  • butter

Bacteria can produce vitamin K2.  As a result, foods that are fermented are rich in vitamin K2.  Animal foods are also high in certain forms of K2.

Vitamin K1 Recipes

What Are the  Symptoms of Vitamin K Deficiency?

Inadequate vitamin K may cause bleeding, conditions of weakened bone density like osteoporosis, and potentially increase your risk of developing heart disease.

Other symptoms of vitamin K deficiency are:

  • bruising easily
  • bleeding excessively
  • small blood clots under nails
  • unexplained hemorrhaging
  • bleeding in mucous membranes inside the body, and
  • stools that are tar-coloured with some blood.

People at risk for vitamin K deficiency include:

  • someone on anticoagulants
  • people taking antibiotics
  • someone diagnosed with a condition affecting nutrient absorption, like irritable bowel syndrome (IBS), celiac’s disease, inflammatory bowel disease (IBD), or a disorder affecting bile production (liver, gallbladder, bile duct diseases)
  • someone diagnosed with cystic fibrosis
  • have a diet deficient in vitamin K, and
  • someone taking statins or osteoporosis medication (lowers conversion of K1 to K2).

Vitamin K is often given to counteract medications that thin the blood, like warfarin, and to newborns to protect from life-threatening bleeding in the skull

Vitamin K Toxicity

Vitamin K toxicity is extremely rare and has mainly been reported from taking synthetic vitamin K forms.  Toxicity has also been reported from the vitamin K shot delivered to newborns.  Symptoms of vitamin K toxicity can look like jaundice, hemolytic anemia, and high bilirubin levels.

Does Vitamin K Cause Blood Clots?

Because of vitamin K’s role in blood clotting, many assume that the vitamin can prompt blood clots to occur.  However, vitamin K is critical for synthesising proteins needed for blood clotting.  Therefore, simply consuming more does not necessarily result in more clotting activity.

However, if someone is taking a medication like warfarin, vitamin K can counteract its effects–even if it’s sourced from food!

Satiety Response to Vitamin K1 in Food

Our satiety analysis indicates that Vitamin K from food has a moderate influence on satiety.  People getting more Vitamin K1 in their food tend to consume 20% fewer calories than those consuming less vitamin K1.  However, this lower food intake may simply correspond to a nutrient-dense, low-energy-density diet loaded with non-starchy green veggies and satiating protein.

Not enough is known about levels of vitamin K that contribute to deficiency to set the DRI.  Subsequently, an Adequate Intake has been set based on the average Vitamin K intake in healthy populations.  

The average intake of Optimisers is 533 micrograms (mcg) per 2000 calories, which is significantly higher than the ‘Adequate Intakes’ of 60 mcg per day for men and 50 micrograms per day for women. 

Optimal Vitamin K1 Intake

Based on our satiety analysis, we have set a K1 stretch target of 1100 mcg for men and 880 mcg for women.  Once you have started to get the hang of nutrient density, you could ‘level up’ by targeting these stretch targets to optimise your nutrition.

Note:  While difficult to track in tools like Cronometer, Chris Masterjohn suggests it could be helpful to aim for at least 100 to 200 mcg of vitamin K2.

Synergistic Nutrients with Vitamin K1

Vitamin K works synergistically with vitamins A, B3, B6, C, calcium, D, E, and manganese.  In other words, vitamin K can’t carry out any of its fundamental processes without the help of these nutrients.  For this reason, we recommend consuming vitamin K from a nutrient-dense diet to ensure you’re consuming the complete profile of all of these vitamins and minerals.

Nutrient Profile of High Vitamin K Foods

The nutrient fingerprint chart below shows that it is straightforward to obtain adequate Vitamin K1 from a nutrient-dense omnivorous diet.  Because foods high in vitamin K1 are typically plant-based foods, they have plenty of protein and fibre and less fat.
