Nature Made Vitamina K2 100 mcg Cápsulas blandas 30 unidades (Paquete de 3)

What is vitamin K2 and why is it important?

Vitamin K2, also known as menaquinone, is a fat-soluble form of vitamin K that plays a key role in the body. Unlike vitamin K1 (phylloquinone), found in leafy green vegetables, K2 is found in fermented foods and animal products, and has superior bioavailability. This essential nutrient contributes to the activation of vitamin K-dependent proteins, such as osteocalcin and matrix GLA proteins, intervening in fundamental processes for bone and cardiovascular health.

This Nature Made supplement offers 100 mcg of vitamin K2 per softgel, in a convenient 3-bottle pack with 30 capsules each, providing up to a 90-day supply. Each softgel is designed for easy swallowing and optimal absorption.

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. Vitamin K2, in particular, helps activate osteocalcin, a protein that fixes calcium in the bone matrix, promoting bone density and strength. It also contributes to cardiovascular health by preventing arterial calcification, maintaining vascular elasticity.

These benefits are backed by a broad scientific consensus and by authorized health claims in the European Union. The consumption of vitamin K2 as a food supplement can be especially useful for people with diets low in fermented foods, those over 50 years old, or those seeking additional support for their bone and circulatory system.

How much vitamin K2 do you need? Recommended dose

The recommended daily dose of vitamin K varies according to age and sex. For adults, the adequate intake is around 70-80 mcg per day for women and 70-80 mcg for men. However, there is no specific reference value for vitamin K2, and many people opt for higher doses to optimize their levels. This product provides 100 mcg per softgel, an amount that meets or exceeds estimated daily needs.

It is recommended to take one softgel daily, preferably with a meal containing fats to improve absorption. Each bottle contains 30 softgels, equivalent to a one-month supply. With the 3-bottle pack, you will have a complete supply for three months.

Differences between vitamin K1 and K2

Vitamin K comes in two main forms: K1 (phylloquinone) and K2 (menaquinone). K1 is found in leafy green vegetables such as spinach, broccoli, and kale, and is primarily used by the liver for the synthesis of coagulation factors. K2, on the other hand, is found in fermented foods such as natto, cheese, and sauerkraut, as well as in animal products. K2 has a longer side chain, which allows it to circulate longer in the blood and reach peripheral tissues such as bones and arteries.

This biological difference makes K2 more effective in activating proteins outside the liver, especially osteocalcin and MGP protein. For this reason, many experts consider that supplementation with K2 is more beneficial for bone and cardiovascular health than with K1.

How to choose the best vitamin K2 supplement

When selecting a vitamin K2 supplement, it is important to look at the specific form: menaquinone-7 (MK-7) is the most studied and has the highest bioavailability. Nature Made uses MK-7, derived from natto, a natural and well-absorbed source. In addition, the softgel format facilitates dosing and absorption, as it is dissolved in a carrier oil.

Also check the purity of the product: this supplement does not contain gluten, soy or other common allergens, and is manufactured under strict quality controls in certified facilities. The package design may vary, but the content and concentration remain consistent.

Possible side effects and contraindications

Vitamin K2 is generally safe at recommended doses. No significant adverse effects have been established for doses up to 100 mcg per day. However, people taking anticoagulants such as warfarin should consult their doctor before using this supplement, as vitamin K can interfere with medication. Pregnant or breastfeeding women should also seek professional advice.

This product is a food supplement and should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of children.
