GNC Vitamina K 100mcg, 180 Comprimidos

Vitamin K, an essential nutrient for your body

Vitamin K is a fat-soluble vitamin essential for various bodily functions. Although often overlooked compared to other vitamins, its role in blood clotting and bone health is crucial. The GNC Vitamin K 100mcg supplement offers you a precise dose of this nutrient in a convenient 180-tablet format, ideal for maintaining optimal levels day after day.

What is vitamin K for?

Vitamin K plays two main functions supported by the European Food Safety Authority (EFSA):

• Contributes to normal blood clotting. Vitamin K is necessary for the synthesis of coagulation factors in the liver, helping the blood clot properly.
• Contributes to the maintenance of bones under normal conditions. It activates osteocalcin, a protein that fixes calcium in the bone matrix, promoting bone density and strength.

Thanks to this double action, vitamin K is especially relevant for people concerned about their bone health, such as postmenopausal women or athletes, and for those who want a healthy circulatory system.

What type of vitamin K to choose?

There are two main forms of vitamin K: K1 (phylloquinone), found in leafy green vegetables, and K2 (menaquinone), of bacterial origin and present in fermented foods. Both are active in the body, although K2 has a longer half-life and is associated with better absorption in bone tissues. This GNC supplement provides vitamin K in its standard form (phylloquinone), offering a reliable and concentrated source to meet your daily needs.

Recommended daily dose

The adequate intake of vitamin K for adults in Spain is around 70-140 mcg per day. Each GNC Vitamin K tablet provides 100 mcg, which represents a moderate dose that suits most people well. It is recommended to take one tablet a day, preferably with a meal that contains some fat to facilitate its absorption. Do not exceed the recommended daily dose.

Synergistic combinations

Vitamin K works closely with other nutrients. Calcium and vitamin D are its main allies: while vitamin D promotes calcium absorption, vitamin K ensures that it is deposited in the bones and not in soft tissues. Magnesium also participates in the activation of vitamin K. Therefore, many people combine this supplement with calcium, magnesium, and vitamin D for a comprehensive approach to bone health.

Possible side effects and precautions

Vitamin K is generally safe, even at higher than recommended doses. However, it can interact with anticoagulant medications such as warfarin (Sintrom). If you are taking these drugs, consult your doctor before starting supplementation. Other possible interactions include broad-spectrum antibiotics and epilepsy medications. As with any supplement, it is important to keep it out of the reach of children and not exceed the indicated dose.

Frequently asked questions

When is the best time to take vitamin K?

It is recommended to take the tablet with the main meal of the day, especially if it contains healthy fats (olive oil, avocado, nuts) to optimize its absorption.

Can I take vitamin K during pregnancy or breastfeeding?

If you are pregnant or breastfeeding, consult your healthcare professional before using any supplement. Needs may vary and personalized advice is important.

Does vitamin K help prevent osteoporosis?

Vitamin K contributes to the maintenance of bones, but it cannot prevent osteoporosis on its own. A balanced diet, exercise, and a healthy lifestyle are essential. Supplementation should complement, not replace, these habits.

Food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose. Keep out of reach of children.
