Product Information

Natural Factors Vitamin K2 features vitamin K2 as menaquinone-7 (MK-7), an advanced, fat-soluble form of vitamin K that serves multiple functions in the body. The K family consists of a trio of vitamins: K1 (phylloquinone), naturally occurring in leafy green vegetables and plant oils; K2 (mena-quinone) present in butter, cows liver, eggs, certain cheeses and natto, a fermented soybean food; and K3, a synthetic form of the vitamin. K3 has been shown to have toxic effects on the liver and K1 doesn’t have adequate benefits for calcium metabolism to dramatically improve osteoporosis or atherosclerosis. Only K2 in the form of MK-7 has been shown to offer 24-hour protection from a single daily dose. Other commercially available subtypes of K2, such as MK-4, only last four to six hours in the body and are required in much larger dosages to be effective. 

Vitamin K1 is easy to obtain from green leafy vegetables. The bacteria in our intestines will convert some of that to K2, but not enough to prevent or treat atherosclerosis and osteoporosis. K2 is found in the diet in natto, a fermented soybean food popular in Japan, as well as in butter, meat, egg yolks, and organ meats from animals that are fed grass instead of grain. As grass-fed animal products are rare nowadays and a taste for natto is difficult to acquire for most Westerners, a vitamin K2 supplement is the best way to ensure you are getting an optimal daily dose of this important nutrient. 

Researchers worldwide are only beginning to uncover the many essential roles that vitamin K2 plays in our health. Our growing understanding of this nutrient is rapidly redefining cardiovascular disease as an illness of nutritional deficiency. In addition, a vitamin K2 deficiency appears to be an underlying factor in the development of diabetes and other cellular disease. Vitamin K2 also plays an essential role in bone metabolism and promoting healthy teeth. Vitamin K2 is naturally occurring in certain fermented foods such as Natto, but for most people, diet alone will not help them meet their daily requirement of vitamin K2. Additionally, medications such as statins (Cholesterol Lowering Drug) and Warfarin (Blood Thinning Drug) further lower the body's level and/or production of vitamin K2. Daily use of Natural Factors Vitamin K2 makes it easy to get optimum levels of this important nutrient.

Conditions associated with K2 deficiency 

  • Osteoporosis
  • Atherosclerosis
  • Diabetes
  • Varicose veins
  • Wrinkles
  • Dental cavities
  • Narrow, crowded dental arch
  • Crohn’s disease
  • Kidney disease

Durable
Color: S6-muti-color
The balls are great for chewers. The squeaky didn’t last long but they are perfect for the ball launcher.

The squeeker isn't durable, but the balls themselves are.
Color: S6-muti-color, Color: S6-muti-color
I have two 70+lb, ball obsessed dogs (a field bred Golden Retriever, and an Old Time Scotch Collie), and these balls are living up to the abuse they're receiving. In the fall we always lose a ball or two in the yard due to getting lost in leaves or longer grass, so I always try and buy a multi pack at the start of the season, so went with these this year. I'm glad I did. Great price for a 6 pack, they fit the medium Chuck-It launcher (a little loosely, but they throw just fine), have great bounce, they FLOAT (which means I didn't lose any at the beach), and they're super durable to the dreaded "mouth squish." The squeaker dies pretty quick, like, within a day, but it isn't the kind that can fall out or choke your dog, so no worries there. The boys are happy, I'm happy, my wallet is happy - I've already ordered another pack.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...
