Nature's Blend Vitamina K1 100 mcg, 100 comprimidos

What is Vitamin K1?

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin essential for the body. It is found naturally in green leafy vegetables such as spinach, broccoli, and kale. This Nature's Blend supplement provides 100 mcg of vitamin K1 per tablet, a suitable dose to meet the recommended daily needs for adults.

Vitamin K1 plays a fundamental role in key physiological processes. Its primary function is related to the activation of vitamin K-dependent proteins, which are involved in blood clotting and bone metabolism.

Benefits backed by EFSA

The European Food Safety Authority (EFSA) has evaluated and approved specific health claims for vitamin K. According to EFSA, vitamin K contributes to normal blood coagulation and the maintenance of normal bones.

These claims are based on solid scientific evidence. Vitamin K activates prothrombin and other clotting factors in the liver, allowing for proper clot formation when an injury occurs. In addition, it intervenes in the carboxylation of osteocalcin, a protein that binds calcium in the bone matrix, helping to maintain bone density and strength.

It is important to note that this product is not intended to diagnose, treat, or prevent any disease. Health claims are approved only in the context of a balanced diet and a healthy lifestyle.

How to take vitamin K1 correctly?

The recommended dose for adults is one tablet per day, providing 100 mcg of vitamin K1. This amount aligns with the reference intake established by European authorities (75 mcg/day for women and 90 mcg/day for men, although some sources recommend up to 120 mcg).

For optimal absorption, it is recommended to take the tablet with a meal that contains some fat, as vitamin K1 is fat-soluble. It can be taken with breakfast, lunch, or dinner. Do not exceed the recommended daily dose unless a healthcare professional advises otherwise.

This supplement is suitable for adults who wish to supplement their dietary intake, especially if they follow restrictive diets or have increased needs. However, it is always preferable to obtain nutrients from food.

Possible contraindications and warnings

Vitamin K1 is generally safe at recommended doses. No significant adverse effects have been established for intakes of up to 100 mcg daily. However, there are situations where caution should be exercised.

People taking anticoagulant medications, such as warfarin (Sintrom®), should consult their doctor before taking any vitamin K supplement. Vitamin K can interfere with the action of these drugs, altering clotting time. The doctor will adjust the anticoagulant dose if necessary.

Likewise, pregnant or breastfeeding women should consult a healthcare professional before using this product. Its use in children is not recommended without medical supervision.

Frequently asked questions

What is the difference between vitamin K1 and K2?

Vitamin K1 (phylloquinone) comes mainly from plant sources and has a shorter half-life in the body. Vitamin K2 (menaquinone) is found in fermented foods and produced by intestinal bacteria, and remains active longer. Both forms perform similar functions, but K1 is the main form used for liver coagulation.

Can I get enough vitamin K1 from diet alone?

A diet rich in green leafy vegetables can provide adequate amounts of vitamin K1. However, people with unbalanced diets, absorption disorders (celiac disease, Crohn's disease), or who take certain medications (broad-spectrum antibiotics) may have deficiencies. In these cases, a supplement may be useful under supervision.
