Shopping guide

Vitamin K supplements can help maintain bone structure in good condition and improve the blood coagulation process, being very important for the proper functioning of the cardiovascular system. However, there are many options on the market, so we have prepared this guide to buy the best vitamin K, so that you can choose a good product.


When making a comparison of vitamins K, it is important to check the label of each product to find out which ingredients have been used in its composition. In this sense, it is good to know that there are two fundamental types of vitamin K, one is phylloquinone or vitamin K1, the other type is called menaquinone or vitamin K2. However, the latter can be found in two forms, MK-4 and MK-7.

Vitamin K2 MK-4 is of animal origin and is the one that the body can absorb more easily, while MK-7 is found in fermented foods, especially derived from soybeans. Its advantage is that it can last longer in the body. Both versions of vitamin K2 are important for properly fixing calcium in the bones, thereby reducing the risk of fractures.

There are very complete products that bring a combination of vitamin K1 and vitamin K2 in its two versions. However, not all supplements include these forms of vitamin K, so it’s important to check the label carefully before making a purchase. In addition, there are products that only have the MK-7 form, so they do not include K1 or K2 MK-4. For this reason, it is good to consult your doctor to find out which is the most appropriate according to the state of your body.

On the other hand, it is important to make sure that the supplement does not contain allergenic ingredients, such as gluten, fructose, lactose and soy. Also, if you have a vegan or vegetarian diet, it must not contain gelatin or substances derived from bees. It is worth mentioning at this point the importance of selecting a quality product that complies with international regulations.


Before asking how much vitamin K costs, it is important to check the product label to find out the concentration, which is nothing more than the amount of nutrients concentrated in each pill. Generally, this measurement is expressed in micrograms (µg) and is listed in the Nutrition Facts box.

There are products that only contain vitamin K2 in its MK-7 form, with a concentration of 100 to 200 µg, depending on the model. Other supplements only incorporate 100 µg of phytomenadione or vitamin K1, which may seem like a low concentration, so it is good to decide with your doctor which is the most appropriate option according to the needs of each person.

As for vitamin complexes that include 2 or 3 forms of vitamin K, it is even more important to analyze the concentration of each nutrient in detail. In these cases, it is possible that the jar expresses, for example, 2200 µg for each capsule, but they can be distributed among the different types of vitamin; 1000 µg of K1, 1000 µg of K2 MK-4 and 200 µg of K2 in its MK-7 form.

In addition, the level of concentration can influence the price of the supplement, so it is good to be sure of what is the real need of our body to make an adequate investment.


As for the presentation, manufacturers usually choose plastic jars with pills, however, we can find some differences that can facilitate the consumption of vitamins K depending on the user’s taste. For example, there are products that come in small tablets, so they are very easy to swallow, while others come in soft capsules that can promote the absorption of nutrients without negatively affecting digestion.

Another good and cheap option to consider is the liquid version of vitamin K, which is very useful for patients with swallowing difficulties. Also, the drops can be placed directly in the mouth or on food and usually have lemon oil or another ingredient that gives them a pleasant flavor.

As for the amount of product, the jars of vitamin K can have between 60 and 360 units, which means that you have enough supply for a period of 2 to 12 months, depending on the concentration and daily dose indicated by the doctor.

Frequently asked questions

Q1: How to use vitamin K?

The use of vitamin K varies according to patients, who can generally be divided into two groups, newborns and adults.

Secondly, by having a direct influence on the bone system, its deficit can cause bone weakening, drastically increasing the risk of suffering from osteoporosis during adulthood and increasing the chances of having fractures.

There are some foods or vegetables that should be avoided when you want to increase the amount of vitamin K through food, since their contribution is too low compared to others. Among the vegetables that provide very little vitamin K are mushrooms, onions, radishes, corn, potatoes, lentils, pumpkins, eggplants, chickpeas, zucchini, red pepper, white beans, among others.

Q5: What is vitamin K for in the newborn?

Vitamin K is of vital importance in newborns, especially when they have problems with blood coagulation, because it prevents bleeding or internal or external bleeding that can occur when there is a deficit of this nutrient. This occurs because until six months of age, when the intestinal bacteria begin their production, babies have very little of this vitamin, which is why doctors and specialists usually recommend the application of an intramuscular injection that allows compensating the lack of vitamin K and balance its levels.

Q6: How long should I take vitamin K?

Treatment with vitamin K varies according to the patient and the severity of their condition, so its duration should be determined by a specialist doctor. However, some manufacturers suggest that in the case of oral consumption in adults to treat osteoporosis, intake should be daily, in case of bleeding disorder, consumption 2 to 3 times per week may be necessary.

Also, to stop the effect of its interaction with other medicines, it should be a single dose but with a high dose. In the case of children, when vitamin K is administered orally to prevent bleeding problems, experts suggest taking 3 doses in a period of 8 weeks and in the case of intramuscular administration, they recommend a single dose.

Q7: Where is vitamin K synthesized?

Vitamin K can be found mainly in green vegetables such as spinach, broccoli, lettuce, cabbage, turnip, among others, but they are also present in foods of animal origin such as eggs, beef and pork liver. Likewise, dairy products, cereals and fruits also provide vitamin K, although in less quantity, so it is important to maintain a balanced diet to guarantee the necessary daily consumption for the body.

On the other hand, it is worth mentioning that the body has its own system to synthesize vitamin K, mainly in the case of menaquinone or MK7, which is synthesized by intestinal bacteria and occurs during fermentation.
