Super K con Complejo Avanzado K2 - 90 cápsulas

What is the vitamin K complex and why is it important?

Vitamin K is a fat-soluble nutrient essential for the body. It comes in two main forms: vitamin K1 (phylloquinone), found in leafy green vegetables, and vitamin K2 (menaquinone), found in fermented foods and animal products. However, many people do not get enough through their diet, especially vitamin K2, which is key to directing calcium to the bones and preventing it from depositing in the arteries.

Super K with Advanced K2 Complex from Life Extension combines these two forms of vitamin K in an easy-to-absorb supplement. It is designed for those seeking bone and cardiovascular support, offering superior bioavailability thanks to its blend of K1 and K2 (as menaquinone-4 and menaquinone-7).

Benefits of vitamin K for health

According to the European Food Safety Authority (EFSA), vitamin K contributes to:

• Normal blood clotting.
• The maintenance of bones under normal conditions.

In addition, the Super K complex is formulated to promote calcium transport to bone tissue, helping to maintain bone density within normal ranges. Vitamin K2 activates proteins such as osteocalcin, which fixes calcium in the bone matrix, and MGP (matrix Gla protein), which prevents arterial calcification. Although EFSA has not approved a specific claim for cardiovascular health, various studies suggest that an adequate intake of vitamin K2 can support arterial elasticity and heart function.*

How much vitamin K do you need? Recommended dose

The recommended daily allowance (RDA) of vitamin K for adults in the EU is 70 micrograms (mcg). However, this amount may be insufficient to maintain optimal blood levels, especially of K2. Super K with Advanced K2 Complex provides a significant amount of vitamin K1 and K2 in each dose, far exceeding the RDA but within established safety limits. It is recommended to take 2 capsules daily with a meal containing fat to improve absorption. If you are taking anticoagulants such as warfarin, consult your doctor before using this supplement.

Differences between vitamin K1 and K2

Vitamin K1 is found mainly in vegetables such as spinach, broccoli, and kale. Its main function is to activate clotting factors in the liver. Vitamin K2, on the other hand, has a longer half-life and is better distributed in extrahepatic tissues. Within K2, there are several subtypes: menaquinone-4 (MK-4) is fast-acting, while menaquinone-7 (MK-7) remains active in the body for up to 24 hours, providing a sustained effect. Life Extension's advanced complex includes both forms of K2 to take advantage of their complementary benefits, along with K1 to ensure complete coverage.

How to choose the best vitamin K supplement

When selecting a vitamin K supplement, it is important to consider the form and bioavailability. Vitamin K2 in the form of naturally occurring MK-7 (such as that extracted from natto) is better absorbed than synthetic forms. Life Extension uses high-quality ingredients and conducts purity and potency tests. This product is suitable for vegetarians (the capsules are plant-based) and contains no gluten, GMOs, or common allergens. In addition, its softgel presentation facilitates swallowing and protects nutrients from oxidation. Store the bottle in a cool, dry place, and keep it out of the reach of children.

Possible side effects and contraindications

Vitamin K is generally safe at recommended doses. However, very high doses can cause mild digestive upset. People taking anticoagulants should avoid vitamin K supplements without medical supervision, as they can interfere with medication. Pregnant or breastfeeding women should consult a healthcare professional before using this product.
