Mason Natural Vitamina K1 100 mcg – 100 Comprimidos (Fitomenadiona)

What is vitamin K1 and why is it important?

Vitamin K1, also known as phylloquinone or phytomenadione, is a fat-soluble vitamin essential for the body. Its main function is related to normal blood clotting, as it is involved in the synthesis of clotting factors in the liver. In addition, vitamin K1 contributes to the maintenance of bones under normal conditions, facilitating the fixation of calcium in the bone matrix. Although it is found naturally in green leafy vegetables such as spinach, broccoli, or kale, many people do not reach the recommended daily intake only through diet, so a supplement can be a practical option.

Benefits endorsed by the EFSA

According to the European Food Safety Authority (EFSA), vitamin K contributes to normal blood clotting and the maintenance of bones under normal conditions. These statements are supported by scientific studies that demonstrate the role of vitamin K in activating proteins such as prothrombin (clotting) and osteocalcin (bone mineralization). It is important to note that these benefits refer to the normal functioning of the body and do not imply the prevention or treatment of diseases. Mason Natural Vitamin K1 provides 100 mcg per tablet, which represents 80% of the reference intake established in the EU.

How to take vitamin K1 correctly?

The recommended dose for adults is one tablet a day, preferably with a meal containing some fat to improve its absorption (for example, with breakfast or the main meal). Do not exceed the indicated dose. Since vitamin K1 is not stored in large quantities in the body, a constant daily intake helps maintain adequate levels. If you are taking anticoagulants (such as warfarin or acenocoumarol), consult your doctor before taking this supplement, as vitamin K1 can interfere with the action of these medications.

Frequently asked questions about vitamin K1

What is the difference between vitamin K1 and K2?

Vitamin K1 (phylloquinone) is found mainly in green vegetables and is primarily used for blood clotting.

Both are important, but K1 is the predominant form in the diet and in most supplements.

Can I take this supplement if I am pregnant or breastfeeding?

It is recommended to consult a healthcare professional before taking any supplement during pregnancy or breastfeeding, although vitamin K1 is generally safe at recommended doses.

How should I store the tablets?

Store in a cool, dry place, at room temperature, and keep the container tightly closed. Avoid direct exposure to sunlight and keep out of reach of children.
