The Mystery of X-Factor Butter Oil and Vitamin K2: Solved

Posted by Kayla Grossmann

“People of the past obtained a substance that modern generations do not have” -Weston A. Price

Traveling the world in search of the secrets of optimal health and immunity, Dr. Weston A Price noted a radiant wellness and unmistakable brilliance in the indigenous peoples of cultures unexposed to a modern diet. After a decade of carrying out the most compelling cross-cultural research around the globe, Price conducted groundbreaking research in his laboratory where he was able to pinpoint particular nutrients responsible for this remarkable robust health. It was through this detailed analysis that he isolated a critical unnamed fat-soluble vitamin he called the X-Factor or Activator X. For years people have searched for this mysterious super nutrient, desirous of its health-giving potential. Well, it turns out the X-factor now has a name: it’s vitamin K2.

The Curious Tale of K2

Vitamin K2 has an interesting history in modern science. A fat-soluble nutrient, it was originally isolated along with its partner, vitamin K1, in a 1943 Nobel Prize winning experiment involving sickly chickens on a low-fat, low-cholesterol diet. While K1 was immediately heralded for its importance in maintaining appropriate blood clotting and coagulation patterns, it's distinctive relative, K2, remained an elusive “mystery vitamin” and was largely forgotten about. It wasn’t until a study published in 1997 that researchers began to understand that vitamin K2 is required for two crucial physiological processes: the delivery of calcium to the bones for appropriate deposition and removal of excess minerals from soft tissues to prevent calcification of vulnerable areas such as the arteries and kidneys. Today, a full understanding of the role of vitamin K2 is still being explored, though building information demonstrates that it is far more critical to bone and cardiovascular health than initially presumed. And what’s more, new studies are revealing that most of the population in modern industrialized cultures are significantly deficient in this essential nutrient.

At the same time that the popular science community was floundering around in a messy process of disjointed scientific studies, an extensive body of innovative work on the subject of K2 was being compiled by a rather non-suspect researcher. This luminary work, published in 1939, was none other than “Nutrition and Physical Degeneration” by Dr. Weston A Price. While Dr. Price did not mention vitamin K2 by name, he wrote extensively about the fat soluble nutrient Activator X, or the X-Factor. He noted that this substance, found namely in the butterfat and organs of grass fed animals, was key to proper bone development, immunity, sound neurological function and dental strength. In 2007, modern research about vitamin K2 and Price's lengthy documentation of the X-Factor were finally linked, bridging a longtime gap in the mainstream understanding of physiological nutrition.

The table below compares Price's discoveries about the X-Factor with modern scientific knowledge about vitamin K2, explaining in a more technical light the processes underlying his novel observations.

Where Has All The Vitamin K2 Gone?

As described by Dr. Price, vitamin K2 is traditionally found in animal products such as meat, fat, dairy and eggs. In an American diet dense with fast food burgers, jiggling egg substitutes and crunchy orange cheez-its, isn’t it shocking that we have such rampant K2 deficiency? Not at all when you consider the quality of our intake. Since the advent of industrialized agriculture our food supplies have become sadly nutrient bereft, and vitamin K2 is among the elements which have been almost completely obliterated. This travesty occurred primarily in the 1940s when farmers realized that livestock could be cheaply fed a diet of grains fortified with synthetic vitamins A and D, and could thus survive without ever having to see the sunlight. With all of the animals raised neatly in massive commercial buildings, production capacity skyrocketed as did profit. Vitamin K2 is synthesized from the chlorophyll ingested by cows, chickens or pigs when grazing in lush green pastures, which means that they must be in the sunshine to get it! When animals are left confined to dark spaces without movement and fed processed grains, there is absolutely no chance for K2 to be created. Today, we unfortunately need to make a highly conscious effort to get K2 into our diet and there are several ways to do so:

  1. Meat, Eggs and Dairy from Grass-fed Animals- Words like “organic,”“free-range,” and “cage-free” don’t mean a thing when it comes to ensuring the nutrient content of these foods. Make sure that animal products are labelled with terms such as "grass-fed" and "pastured." Better yet, find a local farm so that you can visit and ask questions about the treatment of their livestock. The specific type of vitamin K2 found in grass-fed animal products is called MK-4 and it is extremely expensive to replicate. Therefore, all MK-4 supplements are totally synthetic and do not provide the same benefit as these precious foods. Artificial MK-4 is metabolized very quickly in the body and several doses are required per day to maintain K2 levels within a desirable range. The only way to get usable MK-4 is through whole foods. Try making your own raw butter or indulging in beautiful golden grass-fed ghee. Unfortunately, even with these robust foods in your diet, a quality source of supplementation may still be needed to make up for the extremely poor quality in modern soils. 
  2. High Vitamin Butter Oil- This is a precious superfood found extracted by centrifusion from the rich creamy raw milk of grass-fed cows. Its nutrient levels are believed to be many times more concentrated than those in butter and thus less quantities are required for similar health benefits. High quality is a necessity to ensure vitamin K2 content is left intact. Try X-Factor Gold High Vitamin Butter Oil or a High Vitamin Butter Oil/Fermented Cod Liver Oil Blend.
  3. Natto or MK-7 Supplements- Natto is a unique Japanese superfood made from non-GMO fermented soybeans that offers the highest natural concentration of vitamin K2 available. The form of vitamin K2 found in natto is MK-7, which is entirely different from the vitamin K1 found in other plant sources like green leafy vegetables. MK-7 is synthesized through a process of bacterial fermentation, making it a highly bioavailable source of K2. The human body is very receptive to MK-7 and vitamin K2 levels can be efficiently stabilized with lasting effect. Regrettably, the only food source of MK-7 is natto, which many people find difficult to get down due to its potent taste and dense, gooey texture. MK-7 supplements made from natto extract however offer a very effective, all-natural way to get vitamin K2 into a modern diet, requiring only one dose daily to support proper levels. If you are looking for a reliable and healthy way to get adequate amounts vitamin K2, MK-7 supplements may be the best option.
