Vitamin Shoppe Vitamin K2 MK-7 100 mcg – Bone Maintenance & Calcium Regulation – 60 Vegan Capsules

Why Choose Vitamin K2 MK-7?

Vitamin K2, specifically the MK-7 form, is essential for directing calcium to your bones and teeth while helping to prevent its accumulation in soft tissues. This 100 mcg per capsule formula from The Vitamin Shoppe provides a highly bio-available, long-acting version of menaquinone-7 to support your body's natural calcium regulation. Unlike vitamin K1, which is primarily involved in blood clotting, K2 plays a crucial role in bone metabolism and overall health.

Health Benefits of Vitamin K2 MK-7

Vitamin K2 supports several key systems. Its most notable benefits include:

• Bone Health: Activates osteocalcin, which binds calcium to the bone matrix. Adequate K2 intake is linked to higher bone mineral density and reduced fracture risk.
• Calcium Utilisation: Activates matrix Gla protein (MGP), which helps the body direct calcium appropriately, supporting normal calcium balance.
• Dental Health: May contribute to stronger teeth by promoting proper calcium usage.
• Synergy with Vitamin D: Works alongside vitamin D to ensure calcium ends up in bones rather than soft tissues.

Each capsule delivers 100 mcg of pure MK-7 from a vegan source, making it simple to add to your daily routine.

Vitamin K1 vs. K2: Key Differences

Whilst both are forms of vitamin K, they serve distinct purposes. Vitamin K1 (phylloquinone) is found in green leafy vegetables and is primarily used by the liver for blood clotting. Vitamin K2 (menaquinone) is produced by gut bacteria and found in fermented foods like natto. K2 is further divided into MK-4 and MK-7. MK-7, as in this supplement, has a longer half-life, remaining active in the body for up to 72 hours, which allows for once-daily dosage. MK-7 is also more effective at activating osteocalcin (for bone mineralisation) and matrix Gla protein (for calcium regulation).

Recommended Dosage

The typical recommended dosage of vitamin K2 MK-7 for adults is 90–120 mcg per day. This supplement provides 100 mcg per capsule, aligning with standard guidelines. Take one capsule daily with a meal containing fat for optimal absorption. As with any supplement, consult your health care provider before starting, especially if you are on blood-thinning medications like warfarin.

How to Choose a Vitamin K2 Supplement

When selecting a vitamin K2 product, consider these factors:

• Form: MK-7 offers superior bioavailability and duration compared to MK-4.
• Dosage: 100 mcg is an effective daily dose for maintenance and support.
• Purity: Third-party testing ensures the product is free from contaminants and accurately labelled.
• Vegan Certification: This supplement uses a plant-based source of MK-7, suitable for vegans.
• Brand Reputation: The Vitamin Shoppe is a trusted name with rigorous quality control.

Potential Side Effects & Interactions

Vitamin K2 is generally well tolerated. However, because it influences blood clotting, individuals taking anticoagulants should only uses K2 under medical supervision. Excess K2 may reduce the effectiveness of warfarin. Other potential interactions include antibiotics (which reduce gut bacteria that produce K2) and orlistat (which can impair fat absorption). Reported side effects are rare but may include mild digestive upset. Always speak with a physician before combining supplements with prescription medications.

Frequently Asked Questions

Can I take vitamin K2 with vitamin D?

Yes, they work synergistically. Vitamin D promotes calcium absorption, while K2 directs it to bones and away from soft tissues. Many people take them together.

Is MK-7 better than MK-4?

MK-7 has a longer half-life and requires once-daily dosage, whereas MK-4 needs to be taken multiple times daily. MK-7 is also more effective at activating vitamin K-dependent proteins.

What if I’m on blood thinners?

Consult your doctor. Vitamin K can interfere with anticoagulant medications, so it is essential to monitor your intake and keep consistent levels.

How long does it take to see results?

Benefits for bone health and calcium regulation may take several months of consistent uses. Vitamin K2 helps maintain long-term health, not provide immediate effects.
