Jarrow Formulas MK-7 90 mcg - Vitamin K2 (MK-7) Supplement for Bone and Cardiovascular Health - 90 Softgels

Why Choose Vitamin K2 MK-7?

Vitamin K2, specifically the MK-7 form, has become a popular choice for those looking to support bone density and arterial health. Unlike its cousin vitamin K1, which mainly helps with blood clotting, K2 activates proteins that guide calcium into bones and away from arteries. Jarrow Formulas MK-7 delivers 90 mcg of naturally sourced MK-7 from natto (fermented soy), providing a potent dose in a convenient once-daily softgel.

How Does MK-7 Differ from Other Vitamin K Forms?

Many people wonder whether to take vitamin K1 or K2. While K1 is abundant in leafy greens and essential for liver clotting factors, K2 (especially MK-7) has a longer half-life and activates extra-hepatic proteins like osteocalcin and matrix Gla protein. This makes MK-7 the superior form for bone and cardiovascular support. When choosing a supplement, opt for naturally sourced, Non-GM, and allergen-free options like Jarrow Formulas MK-7, which is also gluten free, vegan, and free from common allergens. The softgel includes a small amount of olive oil to enhance absorption of this fat-soluble vitamin.

Recommended Dosage and Usage

The suggested dose for adults is one softgel daily, providing 90 mcg of vitamin K2 as MK-7. This aligns with general recommendations for maintaining bone and heart health. As always, consult your healthcare professional to determine the right dose for your needs, particularly if you are taking blood-thinning medication.

Safety and Potential Interactions

Vitamin K2 is generally well tolerated. However, individuals on anticoagulants like warfarin should avoid vitamin K supplements unless advised by a doctor, as K can interfere with these medications. Other possible interactions include antibiotics and certain cholesterol-lowering drugs. If you are pregnant, breastfeeding, or have allergies to soy—note that this product is derived from natto (soy) but processed to remove most soy protein—consult your healthcare provider before use.

Frequently Asked Questions

Can I take vitamin K2 with other supplements?

Absolutely. Vitamin K2 pairs well with vitamin D3, magnesium, and calcium for comprehensive bone support. Just avoid high-dose vitamin E, which can reduce K activity.

What is the difference between MK-4 and MK-7?

MK-4 is synthetic with a short half-life, requiring multiple doses. MK-7 is natural, has a half-life of about three days, and maintains steady levels with one dose daily.

Is this product safe for long-term use?

Yes, 90 mcg daily is considered safe long-term. It's a food-based nutrient found in traditional diets like natto.

Understanding the Science Behind Vitamin K2

Vitamin K is a fat-soluble vitamin essential for blood clotting and bone metabolism. Vitamin K1 (phylloquinone) is mainly involved in coagulation, while vitamin K2—specifically MK-7—offers unique benefits for bone and cardiovascular health. Jarrow Formulas MK-7 provides 90 mcg of naturally derived vitamin K2 as MK-7, sourced from natto. This bioactive form has a longer half-life, allowing for steady plasma levels with once-daily dosing.
