This mineral is classified as an electrolyte due to the fact that it’s extremely reactive in water. When liquified in water, the produces positively fee ions.

You are watching: Which of the following is the principal positively charged ion inside body cells?

This unique property enables it to conduct electricity, which is necessary for many processes transparent the body.

Interestingly, a potassium-rich diet is attached to many an effective health benefits. It may assist reduce blood pressure and water retention, protect against stroke and aid prevent osteoporosis and kidney stones (1, 2, 3, 4).

This write-up provides a detailed review that potassium and what that does for your health.

What Is Potassium?

Share ~ above Pinterest
Potassium is the 3rd most numerous mineral in the human body (5).

It help the body regulate fluid, send nerve signals and regulate muscle contractions.

Roughly 98% that the potassium in her body is discovered in her cells. Of this, 80% is discovered in her muscle cells, if the other 20% can be uncovered in her bones, liver and red blood cells (6).

Once inside your body, it features as one electrolyte.

When in water, one electrolyte dissolves right into positive or an unfavorable ions that have the ability to conduct electricity. Potassium ions lug a optimistic charge.

Your body offers this electrical energy to regulate a range of processes, including liquid balance, nerve signals and muscle contractions (7, 8).

Therefore, a short or high quantity of electrolytes in the body can influence many vital functions.

Summary: Potassium is an essential mineral that features as one electrolyte. It help regulate fluid balance, nerve signals and also muscle contractions.
It help Regulate fluid Balance

The body is do of around 60% water (9).

40% the this water is uncovered inside your cells in a substance dubbed intracellular fluid (ICF).

The remainder is discovered outside her cells in areas such as your blood, spinal fluid and between cells. This liquid is referred to as extracellular liquid (ECF).

Interestingly, the quantity of water in the ICF and ECF is affected by their concentration that electrolytes, specifically potassium and also sodium.

Potassium is the main electrolyte in the ICF, and also it identify the quantity of water within the cells. Conversely, salt is the key electrolyte in the ECF, and it determines the quantity of water external the cells.

The number of electrolytes loved one to the lot of liquid is dubbed osmolality. Under typical conditions, the osmolality is the very same inside and outside her cells.

Simply put, yes sir an equal balance the electrolytes outside and also inside her cells.

However, when osmolality is unequal, water native the side through fewer electrolytes will move into the next with much more electrolytes to equalize electrolyte concentrations.

This may cause cells come shrink together water moves out of them, or puffy up and burst as water moves into them (10).

That’s why it’s necessary to make sure you consume the ideal electrolytes, including potassium.

Maintaining good fluid balance is important for optimal health. Negative fluid balance have the right to lead come dehydration, which consequently affects the heart and also kidneys (11).

Eating a potassium-rich diet and also staying character language can assist maintain an excellent fluid balance.

Summary: liquid balance is impacted by electrolytes, largely potassium and sodium. Eating a potassium-rich diet can assist you preserve a good fluid balance.

The nervous mechanism relays messages between your brain and body.

These messages are ceded in the type of nerve impulses and assist regulate your muscle contractions, heartbeat, reflexes and many other body attributes (12).

Interestingly, nerve impulses are generated by sodium ions moving into cells and also potassium ions relocating out of cells.

The activity of ions alters the voltage of the cell, which activates a nerve advertise (13).

Unfortunately, a drop in blood level of potassium can affect the body’s capability to generate a nerve impulse (6).

Getting enough potassium from her diet can assist you maintain healthy and balanced nerve function.

Summary: This mineral plays an important role in activating nerve impulses throughout her nervous system. Nerve impulses assist regulate muscle contractions, the heartbeat, reflexes and also many various other processes.

The nervous system helps control muscle contractions.

However, altered blood potassium levels can affect nerve signals in the worried system, weakening muscle contractions.

Both low and also high blood level can impact nerve impulses by altering the voltage that nerve cells (6, 14).

The mineral is likewise important for a healthy heart, together its motion in and out of cell helps keep a continuous heartbeat.

When blood level of the mineral are too high, the heart may come to be dilated and also flaccid. This have the right to weaken the contractions and produce one abnormal heartbeat (8).

Likewise, low levels in the blood can likewise alter the heartbeat (15).

When the love does no beat properly, the cannot successfully pump blood come the brain, organs and also muscles.

In part cases, love arrhythmia, or an rarely often rare heartbeat, deserve to be fatal and also lead come sudden fatality (16).

Summary: Potassium levels have actually a far-reaching effect ~ above muscle contractions. Altered levels can cause muscle weakness, and in the heart, they may cause an rarely often, rarely heartbeat.

Consuming a potassium-rich diet is linked to countless impressive health benefits.

May assist Reduce Blood Pressure

High blood press affects nearly one in 3 Americans (17).

It’s a risk variable for love disease, the leading reason of death global (18).

A potassium-rich diet might reduce blood press by help the body remove excess sodium (18).

High sodium levels deserve to elevate blood pressure, particularly for human being whose blood pressure is already high (19).

An analysis of 33 studies found that when civilization with high blood pressure enhanced their potassium intake, their systolic blood pressure decreased by 3.49 mmHg, while your diastolic blood pressure reduced by 1.96 mmHg (1).

In one more study consisting of 1,285 participants aged 25–64, scientists discovered that civilization who ate the most potassium had diminished blood pressure, compared to people who ate the least.

Those who consumed the most had systolic blood pressure that to be 6 mmHg lower and also diastolic blood pressure that was 4 mmHg lower, on mean (20).

May help Protect against Strokes

A hit occurs when there is a absence of blood circulation to the brain. The the reason of death for much more than 130,000 Americans yearly (21).

Several researches have uncovered that eat a potassium-rich diet may help prevent strokes (1, 22).

In an evaluation of 33 studies consisting of 128,644 participants, scientists found that civilization who ate the most potassium had actually a 24% reduced risk of stroke than people who ate the least (1).

Additionally, an analysis of 11 researches with 247,510 participants found that people who ate the most potassium had a 21% lower risk of stroke. They also found that eating a diet affluent in this mineral was connected to a reduced risk of heart condition (22).

May help Prevent Osteoporosis

Osteoporosis is a condition defined by hollow and also porous bones.

It’s often connected to short levels of calcium, an important mineral because that bone wellness (23).

Interestingly, studies present that a potassium-rich diet may assist prevent osteoporosis by reducing exactly how much calcium the body loses with urine (24, 25, 26).

In a study in 62 healthy women aged 45–55, scientists uncovered that world who ate the many potassium had actually the greatest total bone fixed (2).

In one more study v 994 healthy and balanced premenopausal women, scientists discovered that those that ate the most potassium had much more bone fixed in your lower earlier and hip bones (27).

May assist Prevent Kidney Stones

Kidney stones room clumps of product that may form in focused urine (28).

Calcium is a usual mineral in kidney stones, and several studies display that potassium citrate lowers calcium level in urine (29, 30).

In this way, potassium may assist fight kidney stones.

Many fruits and vegetables contain potassium citrate, therefore it’s straightforward to include to your diet.

In a four-year examine in 45,619 men, scientists found those that consumed the many potassium daily had a 51% lower risk the kidney stones (3).

Similarly, in a 12-year examine in 91,731 women, scientists uncovered that those that consumed the most potassium everyday had a 35% lower risk that kidney stones (31).

It may Reduce Water Retention

Water retention happens once excess fluid builds up inside the body.

Historically, potassium has been provided to act water retention (32).

Studies imply that a high potassium input can help reduce water retention by enhancing urine production and reducing salt levels (4, 33, 34).

Summary: A potassium-rich diet may reduce blood pressure and also water retention, protect against strokes and assist prevent osteoporosis and kidney stones.

Potassium is abundant in countless whole foods, especially fruits, vegetables and also fish.

Most wellness authorities agree that obtaining 3,500–4,700 mg the potassium daily appears to be the optimal amount (35, 36).

Here’s just how much potassium girlfriend can gain from eating a 3.5-ounce (100-gram) serving of foods items rich in this mineral (37).

Beet greens, cooked: 909 mgYams, baked: 670 mgPinto beans, cooked: 646 mgWhite potatoes, baked: 544 mgPortobello mushrooms, grilled: 521 mgAvocado: 485 mgSweet potato, baked: 475 mgSpinach, cooked: 466 mgKale: 447 mgSalmon, cooked: 414 mgBananas: 358 mgPeas, cooked: 271 mg

On the other hand, over-the-counter supplements room not a good way to boost your potassium intake.

In many countries, food authorities limit potassium in over-the-counter supplements to 99 mg, which is much less than the amount girlfriend can obtain from simply one serving of the potassium-rich entirety foods over (38).

This 99-mg border is likely since many studies have uncovered that high doses of potassium native supplements may damages the gut and also even command to fatality by love arrhythmia (38, 39, 40).

However, human being who experience from a potassium deficiency may receive a prescription from their doctor for a higher-dose supplement.

Summary: Potassium is found in a variety of fruits, vegetables and also fish choose salmon. Most health authorities suggest acquiring 3,500–4,700 mg that potassium daily.

Less than 2% that Americans meet the US references for potassium (41).

However, a short potassium intake will rarely reason a deficiency (42, 43).

Instead, deficiencies mostly take place when the body suddenly loses too lot potassium. This may happen with chronic vomiting, chronic diarrhea or in other instances in which you’ve shed a many water (44).

It’s likewise uncommon to acquire too lot potassium. Despite it may take place if you take it too many potassium supplements, over there is no strong evidence that healthy and balanced adults can acquire too lot potassium from foods (45).

Excess blood potassium largely occurs once the body cannot remove the mineral v urine. Therefore, it greatly affects world with bad kidney duty or chronic kidney condition (46).

Additionally, certain populations might need to limit your potassium intake, consisting of those through chronic kidney disease, those acquisition blood push medications and also elderly people, as kidney duty normally declines with age (47, 48, 49).

However, there is some evidence that acquisition too many potassium supplements have the right to be dangerous. Their tiny size renders them easy to overdose on (39, 40).

Consuming too plenty of supplements in ~ once might overcome the kidneys’ ability to remove excess potassium (50).

Nevertheless, it’s crucial to make certain you get sufficient potassium day-to-day for optimal health.

This is particularly true because that older people, because high blood pressure, strokes, kidney stones and osteoporosis are an ext common among the elderly.
