FAQ:

Q: How much vitamin K2 is in Thorne liquid?

A: Thorne’s Vitamin K2 Liquid supplies 1 mg of vitamin K2 per drop. Vitamin K2 liquid can be mixed with a food or a beverage for ease of use for all ages. Thorne has been trusted by health-care practitioners, U.S. National Teams, and families around the world for more than 30 years.

Q: What’s the difference between vitamin K2 and MK-4?

A: Vitamin K2 from animal sources is known as MK-4 while Vitamin K2 produced by bacterial fermentation as found in natto is known as MK-7.

Q: Where does the MK-4 in supplements come from?

A: The MK-4 in supplements is synthetic. It is extracted from tobacco, most likely of GMO origin (90% of tobacco crops are genetically modified). It is not the same MK-4 as found in grassfed butter, eggs, goose liver, gouda cheese or emu oil. The MK-4 in supplements is not derived from grass-fed dairy as this would be prohibitively expensive.

Q: Which is better Mk 4 or Mk 7?

A: Another plus is that MK-7 stays in therapeutic doses in the blood much longer than synthetic MK-4. As a result, a once a day supplement of MK-7 is sufficient to supplement the natural MK-4 that one is getting from a diet high in grassfed dairy and other sacred foods.
