Carlson Labs Vitamina K2-7 45 mcg, 90 Softgels

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

Vitamin K2, also known as menaquinone, is a fat-soluble vitamin essential for the body. Specifically, the MK-7 form (menaquinone-7) is characterized by its high bioavailability and a longer half-life compared to other forms of vitamin K. This Carlson Labs supplement provides 45 mcg of vitamin K2-7 per softgel, a dose that supports key functions such as bone maintenance and circulatory health.

Vitamin K2 activates vitamin K-dependent proteins, such as osteocalcin (for bone mineralization) and matrix Gla protein (for arterial elasticity). By including K2-7 in your daily routine, you help your body efficiently use calcium, directing this mineral to bones and teeth, and preventing its inappropriate deposition in soft tissues.

Health benefits of vitamin K2-7

Vitamin K2-7 contributes to the maintenance of normal bones. This statement is supported by the European Food Safety Authority (EFSA). By activating osteocalcin, K2 facilitates the binding of calcium to the bone matrix, which helps maintain bone density and strength over time.

In addition, vitamin K2 supports cardiovascular health by maintaining the elasticity of blood vessels. The vitamin K-dependent matrix Gla protein helps prevent arterial calcification, thus contributing to healthy circulation. Adequate K2 levels also promote normal blood clotting, although this effect is more related to vitamin K1.

How much vitamin K2-7 do you need? Recommended dose

The recommended dose of this supplement is one softgel daily, preferably with a meal containing fats to optimize its absorption. Each capsule provides 45 mcg of vitamin K2-7 (menaquinone-7), an amount that aligns with the adequate intakes suggested by experts to support bone and cardiovascular health.

For specific populations, such as older people or those with low intake of leafy green vegetables (sources of K1), K2 supplementation may be particularly beneficial. However, it is always advisable to consult a healthcare professional before starting any supplementation, especially if taking anticoagulant medications.

Differences between vitamin K1 and K2, and forms of K2

Vitamin K exists in two main forms: K1 (phylloquinone) and K2 (menaquinone). K1 is found in leafy green vegetables and is primarily used for blood clotting. K2, on the other hand, plays a more prominent role in bone and cardiovascular health. Within K2, there are several subtypes: MK-4 and MK-7 are the most common. MK-7, present in this supplement, is obtained from the fermentation of soybeans (natto) and has a longer half-life, allowing for once-daily dosing. MK-4 has a shorter half-life and requires multiple daily doses.

Choosing the MK-7 form ensures stable blood levels and a sustained effect for 24 hours. In addition, K2-7 is well tolerated and usually does not present negative interactions at moderate doses.

How to choose the best vitamin K2 supplement

When selecting a vitamin K2 supplement, it is important to consider the form (MK-7 is the most effective), the dose (45 mcg is an adequate amount for general maintenance), and the quality of the product. Carlson Labs is a recognized brand that follows strict quality controls. These softgels come in a 90-count package, sufficient for three months of use.

In addition, the supplement is suitable for people looking for a non-GMO and gluten-free option, although this is not specified in the source. Always check the labeling to confirm allergens and certifications.

Possible side effects and contraindications

Vitamin K2-7 is generally safe at recommended doses. No significant adverse effects have been reported with 45 mcg per day. However, people taking anticoagulants (such as warfarin) should consult their doctor before taking vitamin K, as it may interfere with medication. Pregnant or breastfeeding women should also seek professional advice.
