Smarter Vitamin K2 MK7 100mcg with K2VITAL and Kale – 180 Liquid Softgels (3-Pack)

Health Benefits of Vitamin K2

• Bone Health: Vitamin K2 activates osteocalcin, a protein that binds calcium to the bone matrix. This contributes to the maintenance of normal bones, supporting bone density as you age.
• Cardiovascular Support: By activating matrix Gla-protein, vitamin K2 contributes to normal blood clotting and helps maintain healthy blood vessels by directing calcium away from arteries.
• Dental Health: Proper calcium distribution also benefits teeth, supporting enamel strength and overall oral health.
• Synergy with Vitamin D3: Many users combine this K2 with vitamin D3 supplements to maximise calcium utilisation. One reviewer noted that K2 is essential to prevent unwanted calcification when taking D3.

These benefits are supported by decades of research on MK-7, and the inclusion of kale powder adds a natural boost of phytonutrients and antioxidants to your daily regimen.

How to Choose a Vitamin K2 Supplement

When selecting a K2 supplement, look for the MK-7 form from a reputable source like K2VITAL®, which ensures the active trans isomer. This product uses natural fermentation (not synthetic) and includes kale powder for additional nutritional value. The softgels are liquid-filled for better absorption and are free from unnecessary fillers. Smarter Vitamins’ commitment to quality is reflected in the positive feedback from users who appreciate the convenience and reliability of this formulation.

What Is Vitamin K2 (MK-7)?

Vitamin K2, specifically the menaquinone-7 (MK-7) form, is a fat-soluble vitamin that plays a vital role in calcium metabolism. Unlike vitamin K1, which is primarily involved in blood clotting, K2 helps activate proteins that direct calcium to the bones and teeth while preventing it from depositing in soft tissues like arteries. This particular supplement uses K2VITAL®, a premium form of MK-7 that is naturally produced through fermentation and contains the active trans isomer—not the inactive cis form. Each liquid soft gel capsule delivers 100 mcg of bio-available K2, enhanced with kale powder for added nutrients and antioxidants.

Vitamin K2 vs. K1: Key Differences

Both forms of vitamin K are essential, but they serve distinct functions. Vitamin K1 (phylloquinone) is found in green leafy vegetables and is quickly used by the liver for clotting factor synthesis. Vitamin K2, particularly the MK-7 variant, remains active in the bloodstream longer and is more effective at delivering calcium to bones and teeth. K2 also supports normal blood clotting by activating matrix Gla-protein. If you are supplementing with vitamin D3, pairing it with K2 is often recommended because D3 increases calcium absorption, and K2 ensures that calcium is properly utilised—a synergy many users mention in their feedback.

Recommended Dosage

Each soft gel capsule provides 100 mcg of vitamin K2 (as MK-7). The typical recommended dosage is one soft gel capsule per day, taken with a meal that contains fat for optimal absorption. This 3-pack includes three bottles of 60 softgels each, giving you a total of 180 servings—a full six-month supply. As always, consult your health care provider before starting any new supplement, especially if you are on medication.

Potential Side Effects & Interactions

Vitamin K2 is generally well tolerated at recommended doses. However, it can interfere with blood-thinning medications like warfarin (Coumadin) because of its role in clotting. If you are taking anticoagulants, speak with your doctor before using this product. Other potential side effects are rare but may include mild digestive upset. The liquid soft gel capsule form is easy to swallow and gentle on the stomach.
