Vitamin K is a group of fat-soluble vitamins. This group of vitamins includes two natural vitamins: vitamin K1 and vitamin K2. These Vitamins are structurally similar and their name comes from the German word “klotting”.
Vitamin K1, is also known as phylloquinone.
Vitamin K assists with blood clotting, supports the K formation of bone and bone matrix, and aids in
glucose to glycogen conversion for storage in the
liver.

What does it mean if your Vitamin K1 (WBC) result is too low?
Dietary deficiency of vitamin K is extremely rare unless there has been significant damage to the intestinal lining, such as in inflammatory bowel disorders (Crohn’s, ulcerative colitis, etc), liver disease, cystic fibrosis, and fat malabsorption disorders.
Taking broad-spectrum antibiotics can reduce vitamin K production in the gut.
Individuals with chronic kidney disease are at risk for vitamin K deficiency. Individuals with ApoE4 genotype may be at greater risk for low vitamin K.
Since Vitamin K is a fat soluble vitamin, following a chronically low-fat diet can inhibit absorption.
Symptoms of vitamin K depletion or deficiency include: excessive bleeding, menorrhagia, bruises that form easily, or appearance of ruptured capillaries.

Food Sources:
The best sources of Vitamin K1 are plant foods, especially dark green leafy vegetables.
Note: the absorption of vitamin K1 from food is extremely low. Only 10 percent of the vitamin K, which is found in green leafy vegetables, is absorbed in your body. There’s no variable or modification of the consumption that will significantly increase the absorption.
Supplement Options:
The AI for vitamin K is set at 90 μg/day for women and 120 μg/day for men.
Individuals who are on certain anti-clotting medications should consult with their medical provider about their dietary vitamin K intake.
Individuals suffering from blood clotting disorders, osteoporosis, coronary artery disease, cancer, liver disease, celiac disease, Crohn’s disease, ulcerative colitis or cystic fibrosis should discuss dietary intake of vitamin K with their healthcare provider.

What Healthmatters Members Are Saying
I have been using Healthmatters.io since 2021. I travel all over the world and use different doctors and health facilities. This site has allowed me to consolidate all my various test results over 14 years in one place. And every doctor that I show this to has been impressed. Because with any health professional I talk to, I can pull up historical results in seconds. It is invaluable. Even going back to the same doctor, they usually do not have the historical results from their facility in a graph format. That has been very helpful.
