What is the normal potassium level?
Normal serum concentrations of potassium range from about 3.6 to 5.0 mmol/L and are regulated by a variety of mechanisms [ 3, 7 ]. Diarrhea, vomiting, kidney disease, use of certain medications, and other conditions that alter potassium excretion or cause transcellular potassium shifts can cause hypokalemia (serum levels below 3.6 mmol/L) or hyperkalemia (serum levels above 5.0 mmol/L) [ 3, 5, 7, 8 ]. Otherwise, in healthy individuals with normal kidney function, abnormally low or high blood levels of potassium are rare.

Severe potassium deficiency can cause hypokalemia, (serum potassium level less than about 3.6 mmol/L) [ 3, 7, 8 ]. Hypokalemia affects up to 21% of hospitalized patients, usually because of the use of diuretics and other medications [ 29, 30 ], but it is rare among healthy people with normal kidney function.
How much potassium is in the body?
The total amount of potassium in the adult body is about 45 millimole (mmol)/kg body weight (about 140 g for a 175 pound adult; 1 mmol = 1 milliequivalent [mEq] or 39.1 mg potassium) [ 3 ]. Most potassium resides intracellularly, and a small amount is in extracellular fluid [ 2-4 ]. The intracellular concentration of potassium is about 30 times higher than the extracellular concentration, and this difference forms a transmembrane electrochemical gradient that is maintained via the sodium-potassium (Na+/K+) ATPase transporter [ 4 ]. In addition to maintaining cellular tonicity, this gradient is required for proper nerve transmission, muscle contraction, and kidney function.

How to measure sodium intake?
Assessing people’s sodium intakes can be tricky, and the most accurate method known is to measure 24-urine samples over several days. This is the method Harvard researchers used when pooling data from 10,709 generally healthy adults from six prospective cohorts including the Nurses Health Studies I and II, the Health Professionals Follow-up Study, the Prevention of Renal and Vascular End-Stage Disease study, and the Trials of Hypertension Prevention Follow-up studies. [17] They looked at both sodium and potassium intakes in relation to cardiovascular disease (CVD) risk (as noted by a heart attack, stroke, or procedure or surgery needed to repair heart damage), and measured two or more urine samples per participant. After controlling for CVD risk factors, they found that a higher sodium intake was associated with higher CVD risk. For every 1,000 mg increase of urinary sodium per day, there was an 18% increased risk of CVD. But for every 1,000 mg increase of potassium, there was an 18% lower risk of CVD. They also found that a higher sodium-to-potassium ratio was associated with higher CVD risk, that is, eating a higher proportion of salty foods to potassium-rich foods such as fruits, vegetables, legumes, and low-fat dairy.
What foods can help lower blood pressure?
People can make a key dietary change to help lower their risk: Eat more fresh vegetables and fruits, which are naturally high in potassium and low in sodium, but eat less bread, cheese, processed meat, and other processed foods that are high in sodium and low in potassium. Hypertension.
How does potassium affect blood pressure?
Both are essential nutrients that play key roles in maintaining physiological balance, and both have been linked to the risk of chronic diseases, especially cardiovascular disease. High salt intake increases blood pressure, which can lead to heart disease, while high potassium intake can help relax blood vessels and excrete sodium while decreasing blood pressure. Our bodies need far more potassium than sodium each day, but the typical U.S. diet is just the opposite: Americans average about 3,300 milligrams of sodium per day, about 75% of which comes from processed foods, while only getting about 2,900 milligrams of potassium each day. [3,4]
Why does calcium cause bone loss?
According to another theory called “acid-base balance” or “acid-alkaline theory” a high dietary acid load (such as that caused by a high meat and low fruit/vegetable intake) may lead to bone loss if calcium is pulled from bones to help neutralize the acid. It is believed that the breakdown of animal proteins and grains that are high in phosphorus and sulfates generates acid in the body. This causes the kidneys to flush out acid and calcium in the urine.
How much potassium is needed to eat a day?
diet is just the opposite: Americans average about 3,300 milligrams of sodium per day, about 75% of which comes from processed foods, while only getting about 2,900 milligrams of potassium each day. [3,4] A study in the Archives of Internal Medicine found that:

[5]

How to lower blood pressure with potassium?
Try to eat more produce. Higher potassium consumption from foods, especially fruits and vegetables, may lower blood pressure and the risk of heart disease and strokes.
Does potassium help with strokes?
High blood pressure is a leading risk factor for strokes, so it's no surprise that higher potassium is also associated with a lower stroke incidence. One prospective study that followed more than 43,000 men for eight years found that men who consumed the highest amounts of dietary potassium (a median of 4,300 mg per day) were 38% less likely to have a stroke as those whose median intake was just 2,400 mg per day. However, a similar prospective study that followed more than 85,000 women for 14 years found a more modest association between potassium intake and the risk of strokes. Additional research has mostly upheld these findings, with the strongest evidence to support high dietary potassium seen in people with high blood pressure and in blacks, who are more prone to high blood pressure than whites.
Can potassium supplements cause high blood pressure?
Higher potassium consumption from foods, especially fruits and vegetables, may lower blood pressure and the risk of heart disease and strokes. Never take potassium supplements without a doctor's prescription, as this can easily cause high blood potassium levels that are dangerous.
