Source Naturals Vitamina K1 500 mcg - 100 Tabletas de Filoquinona

What is vitamin K1?

Vitamin K1, also known as phylloquinone, is a fat-soluble vitamin naturally found in green leafy vegetables such as spinach, kale, and broccoli. It is essential for the synthesis of proteins involved in blood clotting and bone metabolism. This supplement provides 500 mcg of phylloquinone per tablet, a pure and effective form of vitamin K1.

EFSA-backed benefits

According to the European Food Safety Authority (EFSA), vitamin K contributes to normal blood clotting. In addition, it contributes to the maintenance of normal bones. These benefits are scientifically supported and officially recognized. Phylloquinone acts as a cofactor in the carboxylation of vitamin K-dependent proteins, such as prothrombin and osteocalcin, which explains its role in coagulation and bone health.

How to take vitamin K1 correctly?

The recommended dose is one tablet daily, preferably with a meal containing fats to optimize its absorption. Each tablet provides 500 mcg of phylloquinone, an amount that covers the daily needs of an adult according to European reference intakes. Do not exceed the recommended dose. This supplement is suitable for vegetarians and does not contain yeast, dairy, egg, soy, starch, preservatives or artificial colors.

Possible side effects and contraindications

However, people taking anticoagulants (such as warfarin) should consult their doctor before taking vitamin K supplements, as it may interfere with medication. No significant adverse effects have been reported with proper use. In case of doubt, consult a healthcare professional.
