Msd Manual
However, menadione (a synthetic, water-soluble vitamin K precursor) can cause toxicity (infants have developed hemolytic anemia, hyperbilirubinemia, jaundice, and kernicterus) and should not be used to treat vitamin K deficiency. Vitamin K1 (phylloquinone) is dietary vitamin K. Sources include green leafy vegetables (especially collards, spinach, and salad greens), soy beans, and vegetable oils. Vitamin K2 refers to a group of compounds (menaquinones) synthesized by bacteria in the intestinal tract; the amount synthesized does not satisfy the vitamin K requirement.
The vitamin K–dependent proteins, osteocalcin and matrix gamma-carboxy-glutamyl (Gla) protein, may have important roles in bone and other tissues. Forms of vitamin K are common therapy for osteoporosis in Japan and other countrie.
What Is Vitamin K?
Both vitamin K1 and vitamin K2 produce proteins that help the blood clot.
Blood clotting or coagulation prevents excessive bleeding internally and externally. If a person has a vitamin K deficiency, that means the person’s body cannot produce enough of these proteins, increasing the risk of excessive bleeding. Most adults obtain an adequate supply of vitamin K through the foods they eat and through what their body naturally produces.
Vitamin K deficiency is much more likely to occur in infants.
Benefits
Vitamin K benefits the body in various ways. Bone health There appears to be a correlation between low intake of vitamin K and osteoporosis.
In one study, healthy individuals over the age of 70 years with the highest blood levels of vitamin K1 had the highest verbal episodic memory performance. This enables the heart to pump blood freely through the body. Mineralization naturally occurs with age, and it is a major risk factor for heart disease.
Sources Vitamin K1 occurs in high amounts in leafy green vegetables, such as kale and Swiss chard. Sources of menanoquines, or K2, include meat, dairy products, eggs, and Japanese “natto,” made from fermented soy beans. Here are sample some food sources of vitamin K: 10 sprigs of parsley contains 90 micrograms (mcg)
a 3-ounce serving of natto contains 850 mcg
a half-cup serving of frozen and boiled collard greens contains 530 mcg
one cup of raw spinach contains 145 mcg
1 tablespoon of soybean oil contains 25 mcg
a half-cup serving of grapes contains 11 mcg
a hard-boiled egg contains 4 mcg Most adults in the U.S. Are believed to consume enough vitamin K. Recipe tips These healthy recipes have been developed by a registered dietitian.
Vitamin K
If you have a vitamin K deficiency, then you are more susceptible to osteoporosis. Osteoporosis is a loss of bone density that increases the risk of fracture.
