Jarrow Formulas MK-7 90 mcg Vitamin K2 MK-7 - Bone & Heart Support

In this review of Jarrow Formulas MK-7, the bottom line is simple: this supplement is best for adults who want a focused, bioactive form of vitamin K2 to support bone and cardiovascular health. The product stands out because each softgel supplies a consistent 90 mcg of naturally fermented MK-7, a form shown to be better absorbed than vitamin K1, making it a reliable daily option for directing calcium to bones and supporting arterial health. It is a single-ingredient formula that avoids common allergens, which is a key reason to consider it.

Key Features

• Bioactive MK-7: Provides vitamin K2 as menaquinone-7 derived from natto fermentation, which is absorbed more effectively than K1 for long-term support.
• Consistent dosing: Each softgel delivers 90 mcg of MK-7 so users get a predictable daily amount for bone and cardiovascular maintenance.
• Clean formulation: Made with medium chain triglycerides and olive oil, which support absorption while keeping the ingredient list simple.
• Allergen friendly: Gluten free and free of wheat, soy, dairy, egg, fish/shellfish, peanut/tree nut, and sesame, suitable for many restricted diets.
• Single-ingredient focus: No added vitamins or minerals, which makes it easy to combine with vitamin D3 or calcium regimens without overlap.

Who It's For

This supplement is well suited for adults concerned about bone density or cardiovascular maintenance who already take vitamin D3 or calcium, because MK-7 helps direct calcium to bones. It is also a good choice for people who prefer a minimal, single-ingredient product free of common allergens and unnecessary additives.

Those who should look elsewhere include people seeking a multivitamin or a combined D3+K2 product, and anyone advised by a healthcare professional to avoid vitamin K due to anticoagulant medication or specific medical conditions. Pregnant or nursing individuals should consult a clinician first.
