Source Naturals Vitamina K2 Advantage, 2200 mcg - 120 Comprimidos

What is Vitamin K2 and why is it important?

Vitamin K2, also known as menaquinone, is a fat-soluble nutrient essential for the body. Unlike vitamin K1 (phylloquinone), found in green vegetables, K2 is found in fermented foods and animal products, and plays a key role in activating proteins that regulate blood coagulation and calcium metabolism. In particular, vitamin K2 contributes to the normal utilization of calcium, helping to direct it to bones and teeth and preventing its accumulation in soft tissues. This Source Naturals dietary supplement combines three potent forms of vitamin K2 in a dose of 2200 mcg per tablet, designed to support bone and cardiovascular health.

Health benefits of vitamin K2

According to the European Food Safety Authority (EFSA), vitamin K contributes to normal blood clotting and the maintenance of normal bones. These benefits are backed by decades of scientific research. Vitamin K2 activates osteocalcin, a protein that binds calcium to the bone matrix, and matrix Gla protein (MGP), which inhibits arterial calcification. In this way, K2 promotes bone mineral density and vascular flexibility. In addition, it contributes to the normal functioning of the immune system, as it participates in the regulation of inflammatory responses.

How much vitamin K2 do you need? Recommended dosage

The recommended daily dose for adults may vary depending on age, health status, and sun exposure. However, many experts suggest an intake of between 100 and 300 mcg per day to maintain adequate levels. This product provides 2200 mcg per tablet, a high dose that may be suitable for people with specific needs or low absorption. It is recommended to take 1 tablet daily with a meal, preferably one containing fats to improve absorption. It is always advisable to consult a healthcare professional before starting any supplementation, especially if pregnant, breastfeeding, or taking anticoagulant medications.

Differences between forms of vitamin K2

Vitamin K2 encompasses several forms of menaquinone, the most studied being menaquinone-4 (MK-4) and menaquinone-7 (MK-7). MK-4 is found in animal foods such as liver and egg yolk, while MK-7 comes from bacterial fermentation, such as natto (fermented soybeans). MK-7 has a longer half-life in the blood, allowing for more sustained activation of K2-dependent proteins. Source Naturals Vitamin K2 Advantage combines three forms of menaquinone to offer a complete profile and complementary action. This exclusive formula is designed to maximize bioavailability and efficacy.

Possible side effects and contraindications

Vitamin K2 is generally safe and well tolerated. However, very high doses can interact with anticoagulant medications such as warfarin, as vitamin K counteracts their effect. Therefore, people taking anticoagulants should consult their doctor before using this supplement. The maximum intake levels have not been established by EFSA, but it is recommended not to exceed the indicated dose. In case of experiencing any adverse reaction, discontinue use and consult a healthcare professional.
