With the help of sunlight the body produces Vitamin D.
bacteria in the intestines
vitamin k can be produced in the intestines
Vitamin K is a fat-soluble vitamin produced by bacteria in the GI tract. In needs fat (lipids) to be absorbed by the intestines. You do not need to add extra Vitamin K.
Vitamin K is not found in food but rather is produced by the micro-fauna that inhabits your intestines. Studies on Vitamin K were first done by destroying the micro-fauna in the guts of animals and observing the symptoms they developed - like hemophilia.
The infants stomach/intestines are considered sterile and do not contain the natural flora that is responsible for the synthesis of vitamin K, which helps with the clotting factor so Vitamin K is given to newborn as prophylaxis better safe than sorry.
antibiotics, vitamin K (in the intestines), and synthetic insulin for diabetics.
E. coli are part of the normal flora of the gut. Meaning that they have a home there. They make vitamin K. They also prevent pathogenic bacteria from establishing themselves in the gut. They make it hard for them to get started.
You may not be able to absorb vitamin D if you have certain health conditions. This includes mucus buildup in the intestines and liver problems.
Sometimes antibiotics will cause vitamin K deficiencies. The antibiotic caused the bacteria in the intestines to go all sorts of crazy. When the good bacteria in the intestines is not right it can cause this deficiency.
Vitamin K is not destroyed by any specific vitamin in the intestines. However, certain medications or substances can interfere with the absorption or utilization of vitamin K in the body. These include: Vitamin K antagonists: Medications such as warfarin (Coumadin) and other anticoagulants work by inhibiting the function of vitamin K in the clotting process. They interfere with the activity of vitamin K-dependent clotting factors, which can reduce the blood's ability to clot effectively. However, they do not destroy vitamin K itself. Orlistat: Orlistat is a medication used for weight loss that works by blocking the absorption of dietary fat. Since vitamin K is a fat-soluble vitamin, the use of orlistat may potentially reduce the absorption of vitamin K from food. However, it does not directly destroy vitamin K. Broad-spectrum antibiotics: Some studies suggest that long-term use of broad-spectrum antibiotics may disrupt the balance of gut bacteria, potentially affecting the synthesis of vitamin K by the intestinal bacteria. This could reduce the availability of vitamin K in the body, but it does not destroy vitamin K. It's important to note that these substances do not destroy vitamin K itself but rather interfere with its utilization or absorption in the body. Vitamin K is essential for blood clotting, bone health, and other physiological functions, so it is important to ensure an adequate intake of vitamin K-rich foods or supplements when necessary. If you have concerns about your vitamin K levels or interactions with certain medications, it is best to consult with a healthcare professional or a registered dietitian who can provide personalized advice based on your specific situation and medical history.
The main purpose of Vitamin K is to aid in the clotting process. Vitamin K is important as part of the blood clotting mechanism of the body.
