Vitamin K deficiency – take care of it in time

Vitamin K is a fat-soluble substance that remains relatively unknown to the general public compared to other vitamins. However, its role in maintaining vital functions in the body is more than significant. There are different forms of this vitamin, the most important of which are K1 (phylloquinone) - found mainly in green leafy vegetables, and K2 (menaquinone) - found in animal products and fermented foods. 

Vitamin K deficiency is not among the most common deficiencies in the body, but it can seriously affect health under certain conditions. The risk group includes people with chronic intestinal diseases that make it difficult to absorb fats, people taking long-term antibiotics or anticoagulants, as well as elderly people who eat an unbalanced diet.

Vitamin K – what it helps with, its essence and role in the body

Vitamin K is involved in complex biochemical mechanisms that maintain balance in a number of vital systems. It activates specific proteins that regulate blood clotting, bone mineralization, and cellular metabolic activity. This vitamin is also indispensable in processes related to heart health and calcium metabolism.

• Blood clotting – supports the synthesis of proteins necessary for proper blood clotting.
  
• Healthy bones – activates osteocalcin, or a protein that binds calcium in bone tissue.
  
• Cardiovascular health – reduces calcium accumulation in the arteries, preventing calcification.
  
• Metabolic balance – participates in the regulation of insulin sensitivity and other metabolic functions.
  
• Skin health – promotes wound healing and reduces the appearance of bruises.
  

Vitamin K deficiency - symptoms

Vitamin K deficiency may go unnoticed in its early stages, as symptoms appear gradually. However, with a longer-term deficiency, the body shows clear signals that should not be ignored:

• Frequent and easy bruising;
  
• Prolonged bleeding from cuts;
  
• Bleeding from the nose or gums;
  
• Heavy menstrual bleeding;
  
• Blood in the urine or stool;
  
• Reduced bone density and frequent fractures;
  
• Delayed wound healing.
  

Vitamin K deficiency – potential problems

The ongoing shortage of vitamin K can lead to serious health complications. Blood clotting disorders increase the risk of internal bleeding and heavy bleeding even from minor injuries. 

Weakening of bone structure increases the likelihood of osteoporosis and bone fractures, especially in older people. The accumulation of calcium in soft tissues, including the arteries, is associated with an increased risk of cardiovascular disease. 

Furthermore, if not compensated for in time, vitamin K deficiency in pregnant women can affect blood clotting in the newborn.

How to drink vitamin K

Vitamin K intake depends on the form and purpose of use. For optimal results, it is important to consider both the daily dose and the food with which it is taken. Individual needs and health status also affect the amount needed and the duration of intake.

With or without food: Because it is fat-soluble, vitamin K is best absorbed when taken with food containing fat – such as olive oil, avocados or nuts.

At what time of day: There is no strictly fixed time, but for optimal effect it is recommended to take it with a main meal.
 

Recommended daily dose: for adults ranges between 90-120 micrograms, depending on gender and health condition. For specific needs (e.g. osteoporosis), the doctor may recommend a higher dosage.

Forms of administration: It is available in the form of drops, tablets and capsules – both alone and as part of complex formulas.

Attention: In people taking anticoagulants, vitamin K intake should be coordinated with a specialist to avoid disrupting the effect of the therapy.

Vitamin K - combinations with other vitamins and minerals
 

Vitamin K is often included in synergistic formulas because its effects are enhanced when properly combined with other nutrients. Combinations support multiple physiological processes simultaneously and increase overall bioavailability.

Vitamin K + Vitamin D

This combination is extremely important for bone and cardiovascular health. Vitamin D helps absorb calcium, and vitamin K directs calcium to the bones and prevents it from depositing in the arteries.

Vitamin K in complex with A, D and E

The combination of vitamin K with other fat-soluble vitamins creates complete antioxidant and metabolic support. Together, they enhance cell defenses, immune response, and maintain healthy hormonal balance.

Calcium and magnesium + vitamin K

They are often included together in bone density supplements. Calcium builds structure, magnesium aids in enzymatic reactions, and vitamin K regulates proper mineral deposition.

The balance that should not be underestimated

Vitamin K is a vital element, the importance of which for health is often underestimated. Its regular intake, especially in risk groups, supports the functions of the body and provides protection for the bone and cardiovascular system. Combined with a balanced diet and appropriate supplements, vitamin K contributes to the long-term maintenance of physiological balance.
