Health Benefits of Vitamin K2
Vitamin K2, in the form of menaquinone-7 (MK-7), is a fat-soluble vitamin that supports healthy calcium metabolism. By activating key proteins like osteocalcin and matrix Gla-protein, it helps direct calcium to your bones and teeth while preventing arterial calcification. This supplement delivers 100 mcg of K2VITAL® MK-7 per liquid softgel, enhanced with kale powder for added phytonutrients.
-
Bone Health: K2 activates osteocalcin, which binds calcium to the bone matrix. Over time, this helps maintain bone density and reduce fracture risk.
-
Cardiovascular Support: Matrix Gla-protein activation helps prevent calcium buildup in arterial walls, supporting healthy blood vessels and circulation.
-
Dental Health: Proper calcium distribution also strengthens tooth enamel and contributes to overall oral health.
-
Synergy with Vitamin D3: Many Canadians combine this K2 with vitamin D3 to optimize calcium utilization—ensuring calcium goes where it’s needed most.
How to Choose a Vitamin K2 Supplement
Quality matters when selecting a K2 supplement. Look for the MK-7 form from a reputable source like K2VITAL®, which guarantees the active trans isomer. This product is naturally fermented (not synthetic) and includes kale powder for extra nutritional value. The liquid softgels are designed for better absorption and contain No unnecessary fillers. Positive consumer feedback highlights the convenience and reliability of this formulation from Smarter Vitamins.
What Is Vitamin K2 (MK-7)?
Vitamin K2, specifically menaquinone-7, is a fat-soluble vitamin that plays a critical role in calcium metabolism. Unlike vitamin K1 (phylloquinone), which is primarily used for blood clotting, K2 stays active in the bloodstream longer and helps direct calcium to bones and teeth. This supplement uses K2VITAL®, a premium MK-7 derived from natural fermentation that contains only the active trans isomer. Each softgel provides 100 mcg of bioavailable K2, with kale powder for added antioxidants.
Vitamin K2 vs. K1: Key Differences
Both forms of vitamin K are essential, but their functions differ. Vitamin K1 is found in green leafy vegetables and is rapidly used by the liver for clotting factor synthesis. Vitamin K2, especially MK-7, remains active longer and is more effective at delivering calcium to bones and teeth. By activating matrix Gla-protein, it also supports cardiovascular health by preventing arterial calcification. Pairing vitamin D3 with K2 is common because D3 boosts calcium absorption; K2 then ensures proper calcium distribution.
Recommended Dosage
Take one softgel per day with a meal containing fat for optimal absorption. Each softgel contains 100 mcg of vitamin K2 (as MK-7). This 3-pack includes three bottles of 60 softgels each, providing a total of 180 servings—a convenient six-month supply. Always consult your healthcare provider before starting a new supplement, particularly if you are on other medications.
Potential Side Effects & Interactions
Vitamin K2 is generally well-tolerated at recommended doses. However, it may interfere with blood-thinning medications such as warfarin because of its role in clotting. If you take anticoagulants, speak with your doctor before use. Other side effects are rare but might include mild digestive upset. The liquid softgel form is easy to swallow and gentle on the stomach.
