Jarrow Formulas MK-7

Need an extra boost of vitamin K? Jarrow Formulas MK-7 has got you covered with an ultra-absorbable form of vitamin K2!*

Did you know that vitamin K comes in multiple forms? K1 is the most common, and it’s found in green veggies like spinach. K2 occurs in animal products or fermented foods (think sauerkraut, kombucha, yogurt, or raw dairy products). Both types are also produced in your own digestive system! However, Jarrow Formulas MK-7 uses a synthetic version of vitamin K2 because it stays active for longer within your body, and it is more easily absorbed than vitamin K1.*

  • Vitamin K2 (known as Menaquinone-7)*
  • Easy to absorb*
  • Builds stronger bones*
  • Prevents arterial calcification*
  • Promotes proper formation of blood clots*
  • Protects the brain and nervous system from oxidative stress*

Bones: We all know that calcium helps strengthen our bones. Vitamin K plays a role as well! It directly increases the protein that is responsible for maintaining calcium in your bones. Pair Jarrow Formulas MK-7 with a calcium supplement for extra bone support!* 

Heart health: Flexible veins and arteries keep your blood flowing smoothly. Vitamin K helps remove and prevent rigid calcification buildup on your arteries so your heart beats strongly!*

Blood: What happens when you get a small cut? It bleeds, and then it magically stops! What is actually happening is that your blood clots and a small scab forms. Vitamin K plays a role in this process by encouraging healthy blood clotting and coagulation.*

Brain: Vitamin K contributes to healthy mobility and cognition, and offers your brain and nervous system antioxidant protection!* 

Jarrow Formulas® MK-7 is naturally made via fermentation by Bacillus subtilis subsp. natto and is much better absorbed than K1 from spinach.* MK-7 is a longer-acting form of vitamin K vs. K1 and MK-4, and better supports carboxylation of specific proteins needed to build bones and support cardiovascular health.*

Suggested Use: Take 1 softgel per day or as directed by your qualified healthcare professional.

Cautions: Keep out of the reach of children. Consult a physician before taking this product if you are trying to conceive, pregnant, or lactating, under the age of 18, taking any medications (especially anticoagulants [e.g. warfarin/Coumadin]), or have a medical condition.

Jarrow Formulas began in 1977 when Jarrow L. Rogovin would personally deliver his self-made herbal supplements to local health food stores. By the 1980s, Jarrow expanded his small operation into his own health food store in West Hollywood, California. Jarrow set his company apart from the competition by focusing his efforts on formulating supplements based on innovative scientific research. What once began as a small, local service has expanded into an internationally renowned health supplement company. 

Jarrow Formulas centers its mission around scientific research, even funding research studies on their own products such as Bone-Up, Co-Q10 Ubiquinol, JarroSil, and more. In 2000, Jarrow Formulas established Jarrow Industries, Inc. as their main manufacturer, allowing for the manufacturing of each product to be supported and verified for quality from start to finish. Jarrow Formulas’ state-of-the-art laboratories enlist a staff of specialists to ensure their products meet the highest standards of quality assurance. 

For nearly two decades, Jarrow Formulas has garnered the interest of the health industry and has even accumulated 37 awards for their innovative supplements! Some awards include:

  • Consumer Lab #1 Probiotics for Customer Satisfaction: 2019, 2021
  • Taste For Life Magazine Essentials Award: 2017, 2019
  • Better Nutrition Magazine Best of Supplements Award: 2008, 2009, 2010, 2011, 2013, 2015, 2016, 2017
  • Vitamin Retailer Magazine Vity Award: 2004, 2005, 2006, 2007, 2008, 2010, 2013
  • NutraIngredients USA Awards, Probiotic Product of the Year: 2008
