What is vitamin K2?
There are three types of vitamins in the K complex:
- Phytomenadione, also called K1, which can be found in dark green leafy vegetables.
- Menaquinone, known as K2, which is present in fermented foods.
- Menadione, vitamin K3, produced in the laboratory.
Among the three types, vitamin K2 stands out for three reasons: it is completely absorbed by the body (bioavailable), acts for a longer time in the body (bioactive) and has numerous benefits.
Vitamin K2 is produced naturally by healthy intestinal bacteria. However, in addition to low absorption, production falls over the years, causing deficiency in the body.
So it is essential to consume foods that are sources of the vitamin (some types of cheese, meat, eggs and fermented foods) and include a supplement.
What are the benefits of vitamin K2?
This vitamin started to attract the attention of scientists, when it was discovered that vitamin K2 potentiates the effects of vitamin D3 (when they are used together).
Among the effects are: production of new bone cells, strengthening of bones, control of calcium levels, increase in bone mass and density. Such benefits help to prevent osteoporosis and bone fractures.
Vitamin K2 also prevents calcium from being directed to inappropriate areas of the body such as arteries, joints, kidneys, eyes and gallbladder. When they are absorbed in these regions they can cause atherosclerosis, arthrosis, kidney stones, cataracts and vesicular stones, respectively.
Vitamin K2 is important for producing the osteocalcin (GLA) protein that is part of the bone structure and is responsible for preventing the accumulation of minerals in the veins and arteries.
Another function is to prevent calcium from mineralizing in the arteries that lead to the heart, which can cause hardening of the heart valves, clogging of the arteries and a possible infarction.
But vitamin K2 has other benefits besides those mentioned above, such as helping blood clotting, activating the vascular system, inhibiting the development of varicose veins, preventing infectious diseases and brain problems.
The vitamin also helps to rule out some types of cancer, as it suppresses the genes that can develop these diseases and strengthens the genes that synthesize healthy cells and fight cancer.
Prevention of cardiovascular diseases
Vitamin K2 also helps to strengthen the cardiovascular system, inhibiting the development of cardiovascular diseases, decreasing the risk of stroke and stroke.
- Promotes blood clotting
- Strengthens veins and arteries
- Strengthens the heart muscle
- Prevents vascular calcification
Improves physical performance
Vitamin K2 supplementation can also improve your performance in sports, as it increases the body’s ability to use the energy produced by the body itself to move.
This is because vitamin K2 acts on the pancreas and promotes the production of insulin, which among other effects, increases energy and promotes cell nutrition.
Prevention of obesity and diabetes
Vitamin K2 prevents and prevents the advance of type 2 diabetes, as it increases insulin sensitivity, which helps to stabilize blood glucose levels, and prevents the accumulation of visceral fat.
These benefits also prevent the development of an increasingly common metabolic problem in our society: obesity.
Improves sexual health
Vitamin K2 also helps improve sexual health by optimizing the function of testosterone, which causes a drop in estrogen levels, increasing male fertility.
Another benefit is that the supplement increases sperm production. In women with Polycystic Ovary Syndrome, vitamin K2 helps to regulate testosterone levels.
Another benefit is the improvement in blood supply to the genitals of men and women.
When there is a low concentration of vitamin K in the body and a high concentration of cytokines, the likelihood of developing inflammation is greatly increased. Vitamin K2 reduces the rates of cytokine in the body.
This benefit makes the vitamin K2 supplement ideal for people with inflammatory diseases such as Lupus, Crohn’s disease, diabetes, among others.
Improves teeth health
As with bones, vitamin K2 helps to strengthen teeth. This is because the vitamin facilitates the absorption of calcium by the teeth and stimulates the dentin, which helps to structure the teeth and make them healthier.
Stimulates mitochondrial function
Vitamin K2 helps to stimulate mitochondrial function, as it assists in the transport of electrons to mitochondria, which accelerates mitochondrial function, generating more energy.
Because of this benefit, the possibility of using the vitamin K2 supplement to treat liver problems and degenerative diseases in the central nervous system is already being studied.

Purchasing Criteria: Factors to compare the different models of vitamin K2
There are few differences between vitamin K2 supplements. But, although few, these distinctions can make all the difference in the effectiveness and durability of the product. When buying yours, review the following criteria:
- MK4 or MK7?
- Number of capsules
We will explain each of the items below.
MK4 or MK7?
When you are looking for a vitamin K2 supplement you will find many products with the indication MK7 and others with the indication MK4 on the label. This creates doubts in many people, so let’s explain what this information is about.
Vitamin K2 has four variations: MK4, MK7, MK8 and MK9. The difference between them is the length of the side chain, the longer the better the efficiency.
The two variations used in the composition of vitamin K2 supplements are MK4 and MK7, we explain the differences between them in the table below:
|Time remaining in the organism||Shortly stays in the bloodstream||About three days|
|Absorption||Effective||Fully absorbed by the body|
|Concentration||Between 100 and 1300 mcg||From 65 to 120 mcg|
You can find vitamin K2 supplements in the following concentrations: 65 mcg, 100 mcg and 120 mcg (MK7), or in higher doses, which reach 1300 mcg (MK4).
According to experts, the recommended daily dose is 120 mcg of vitamin K2 type MK7, which is the most effective, due to the ease of absorption and bioavailability (the time the substance remains in the body).
When buying a vitamin K2 supplement, it is essential that you look at the bottle of the product. Vitamin K2 is sensitive to light, so the bottle must be dark or at least opaque to prevent the capsules from contacting the light.
Number of capsules
Vitamin K2 supplement is sold in capsules. The recommended daily dose is always one capsule a day, either in the morning or during one of the main meals.
The amount of capsules per bottle varies between 60, 90 or 100 units. The vitamin K2 supplement can be purchased ready-made or you can have it handled (in this case, look for a reliable handling pharmacy).
