Superior Source Vitamina K2 MK-7 (Menaquinona-7), 300 mcg - 60 comprimidos sublinguales

What is vitamin K2 MK-7 and why is it important?

Vitamin K is a fat-soluble nutrient essential for various bodily functions. There are two main forms: K1 (phylloquinone), found in green leafy vegetables, and K2 (menaquinone), produced by bacteria and found in fermented foods. Menaquinone-7 (MK-7) is a subform of vitamin K2 with a prolonged half-life, allowing for sustained release in the body. This characteristic makes it a prominent option for those seeking continuous support for bone and cardiovascular health.

Vitamin K2 MK-7 acts by activating proteins that regulate calcium distribution in the body. Specifically, it activates osteocalcin, which helps bind calcium to bones, and matrix Gla protein (MGP), which prevents calcium accumulation in arteries. In this way, it contributes to maintaining strong bones and healthy cardiovascular function.

Key benefits of vitamin K2 MK-7

Vitamin K contributes to the maintenance of normal bones and normal blood clotting. These are the benefits supported by the European Food Safety Authority (EFSA). By ensuring that calcium is properly deposited in bones, vitamin K2 MK-7 promotes bone density and reduces the risk of fragility. In addition, by keeping arteries flexible and free of calcification, it supports the health of the circulatory system.

For people on vegan or vegetarian diets, vitamin K2 can be more difficult to obtain through food, as the main sources are fermented foods like natto or animal products. A high-quality MK-7 supplement effectively meets this need.

Different forms: MK-7 vs MK-4

Vitamin K2 comes in several forms, the most common being MK-4 and MK-7. MK-4 has a short half-life (a few hours) and is found in small amounts in foods such as liver or egg yolk. In contrast, MK-7, derived from natto, remains active in the body for up to 24 hours, allowing for a single daily dose with stable blood levels. Additionally, MK-7 is better absorbed in the intestine, making it especially suitable for people with delicate digestions.

Superior Source has selected the MK-7 form in its 300 mcg dose, an amount supported by studies to optimize the activation of vitamin K-dependent proteins.

Why choose sublingual tablets?

Sublingual tablets offer a unique advantage: they dissolve quickly under the tongue and nutrients pass directly into the bloodstream through the oral mucosa, bypassing the digestive tract. This is especially beneficial for people with intestinal absorption problems, bariatric surgery, or difficulty swallowing pills. Superior Source's rapid dissolution technology ensures that the active ingredient is immediately available, maximizing bioavailability.

In addition, these tablets are small, easy to transport, and do not require water. Simply place them under the tongue and wait a few seconds for them to dissolve.

Who can benefit from this supplement?

Vitamin K2 MK-7 is suitable for a wide range of people: those who wish to maintain bone health as they age, postmenopausal women, athletes looking to strengthen their musculoskeletal system, people with restrictive diets (vegans, vegetarians), and those who have undergone bariatric surgery or suffer from malabsorption. It is also a smart option for those taking antibiotics for prolonged periods, as these can alter intestinal vitamin K2 production.

It is important to consult a healthcare professional before starting any supplementation, especially if taking anticoagulants (warfarin, acenocoumarol), as vitamin K interferes with their mechanism of action.

Dosage and recommendations for use

It is recommended to take one sublingual tablet daily. Place the tablet under the tongue and hold it until it dissolves completely. Do not chew or swallow whole. For best results, take it at approximately the same time each day, preferably with a meal containing some fat to facilitate the absorption of vitamin K, which is fat-soluble.

Each pack contains 60 tablets, equivalent to a two-month supply. Store in a cool, dry place, out of reach of children.

Frequently asked questions (FAQ)

Can I take vitamin K2 MK-7 with other supplements?

Yes, vitamin K2 is often combined with vitamin D3 and calcium to enhance bone health. Vitamin D3 improves calcium absorption, while K2 directs it to the bones. However, it is always advisable to consult a professional to adjust doses.

Is it safe for people with allergies?

This product is gluten-free, lactose-free, and soy-free, and is suitable for vegans. However, check the complete ingredient list to ensure there are no specific allergens.

How long should I take it to see results?

Bone and cardiovascular benefits are seen with continued use. MK-7 accumulates in the body, so it is recommended to take it for at least three months to observe significant changes.

Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended dose. Keep out of reach of children. This product is not intended to diagnose, treat, cure, or prevent any disease.
