Vitamin K is a nutrient that the body needs to stay healthy. It's important for blood clotting and healthy bones and also has other functions in the body. If you are taking a blood thinner such as warfarin (Coumadin®), it's very important to get about the same amount of vitamin K each day.
Vitamin K is used by the body to help blood clot. Warfarin (Coumadin) is used to slow blood clotting. By helping the blood clot, vitamin K might decrease the effectiveness of warfarin.
One study showed that a single serving of natto rich in vitamin K2 altered measures of blood clotting for up to four days. This was a much larger effect than foods high in vitamin K1 ( 10 ).
Some foods and other substances that may act as natural blood thinners and help reduce the risk of clots include the following list:
- Turmeric. Share on Pinterest.
- Ginger. Share on Pinterest.
- Cayenne peppers. Share on Pinterest.
- Vitamin E. Share on Pinterest.
- Garlic.
- Cassia cinnamon.
- Ginkgo biloba.
- Grape seed extract.
Vitamin K normally helps your blood clot so wounds don't bleed too much. Warfarin works against vitamin K, making your blood clot more slowly.
Vitamin K helps to regulate the process of blood coagulation by assisting in the conversion certain coagulation factors into their mature forms. Without vitamin K, our bodies would be unable to control clot formation.
Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury. Typically, your body will naturally dissolve the blood clot after the injury has healed.
Kidney disease: Too much vitamin K can be harmful if you are receiving dialysis treatments due to kidney disease. Liver disease: Vitamin K is not effective for treating clotting problems caused by severe liver disease. In fact, high doses of vitamin K can make clotting problems worse in these people.
Juice from potassium-rich fruit is also a good choice: Orange juice. Tomato juice. Prune juice.
The short answer is no, you should not take potassium supplements unless your doctor prescribes them. Let me outline why below. To start with, you're much better off getting potassium from foods instead of potassium supplements.
Vitamin D3 tended to increase retention of both potassium and sodium in the body.
Citrus fruits like oranges are well known for being high in vitamin C, but they're also a good source of potassium. One cup (248 grams) of orange juice provides 496 mg of potassium. It's also rich in folate, vitamin A, thiamine, and antioxidants ( 34 , 35 , 36 ).
Potassium chloride is the most common type used to treat deficiency. The recommended daily intake (RDI) for potassium is 4,700 mg. Most supplements come in 90 mg to 99 mg doses of potassium. Higher-dose pills are available, but they usually contain smaller “active” amounts.
In hypokalemia, the level of potassium in blood is too low. A low potassium level has many causes but usually results from vomiting, diarrhea, adrenal gland disorders, or use of diuretics. A low potassium level can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop.
The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart.
Potassium is a mineral on the periodic table represented by the letter K, and an electrolyte. Your body needs electrolytes to conduct electricity. Potassium also functions along with sodium to help your body maintain water balance.
Adults should consume about 3,500mg of potassium per day, according to the UK's National Health Service. The average banana, weighing 125g, contains 450mg of potassium, meaning a healthy person can consume at least seven-and-half bananas before reaching the recommended level.
cup of black coffee has 116 mg of potassium3. This is considered a low potassium food. However, many people drink more than one cup of coffee each day. Three to four cups of coffee a day is considered high in potassium and could raise your potassium levels.
Drinking too much water can cause side effects that range from mildly irritating to life-threatening — and overhydration can lead to an imbalance of electrolytes in the body. Electrolytes such as potassium, sodium, and magnesium help regulate everything from your kidneys to your heart function.
It can cause:
- Muscle fatigue.
- Weakness.
- Paralysis.
- Abnormal heart rhythms (arrhythmias)
- Nausea.
Professor Fiona Karet, co-founder of Kalium and professor of nephrology at the University of Cambridge said: “Currently, there is no medically approved, accurate blood potassium test available for use outside of hospital or centralised lab settings.
Meat, fish, poultry and eggs are moderate to high sources of potassium. These foods are also good sources of high-quality protein, which you need for normal body functions. Follow the guidelines for protein needed in your diet. Some fruits and vegetables can also add a lot of potassium to your diet.
Low-potassium foods (less than 50 mg per serving):1 ounce of cheese (20 to 30)
However, when kidneys do not work well, they may not be able to remove enough potassium. This means that potassium can build up in your blood to harmful levels. Eat a diet high in potassium. Eating too much food that is high in potassium can also cause hyperkalemia, especially in people with advanced kidney disease.
Low-Potassium Foods
- Apples (plus apple juice and applesauce)
- Blackberries.
- Blueberries.
- Cranberries.
- Fruit cocktail.
- Grapes and grape juice.
- Grapefruit.
- Mandarin oranges.
Some of the vitamins found in
honey include ascorbic acid, pantothenic acid, niacin and riboflavin; along with minerals such as calcium, copper, iron, magnesium, manganese, phosphorus,
potassium and zinc.

A healthy adult should aim to consume 3,500–4,700 mg daily from foods. To increase your intake, incorporate a few potassium-rich foods into your diet such as spinach, yams, avocados, bananas, and fish, such as salmon.
Potassium citrate side effects
- confusion, anxiety, feeling like you might pass out;
- uneven heartbeat;
- extreme thirst, increased urination;
- leg discomfort;
- muscle weakness or limp feeling;
- numbness or tingly feeling in your hands or feet, or around your mouth;
- severe stomach pain, ongoing diarrhea or vomiting;
Getting too little potassium can increase blood pressure, deplete calcium in bones, and increase the risk of kidney stones. Prolonged diarrhea or vomiting, laxative abuse, diuretic use, eating clay, heavy sweating, dialysis, or using certain medications can cause severe potassium deficiency.
Severe dehydration from prolonged diarrhea and vomiting can be dangerous. You are losing more than moisture as time goes on if you are fighting chronic diarrhea. Along with the fluids you are losing, your body can lose minerals such as potassium.
A low potassium level has many causes but usually results from vomiting, diarrhea, adrenal gland disorders, or use of diuretics. A low potassium level can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop.
The more potassium you eat, the more sodium you lose through urine. Potassium also helps to ease tension in your blood vessel walls, which helps further lower blood pressure. Increasing potassium through diet is recommended in adults with blood pressure above 120/80 who are otherwise healthy.
