Have you ever had sudden, painful cramps that just don’t seem to go away? One potential cause is that you are low in potassium. Low potassium levels can also cause muscle weakness, fatigue, muscle spasms, tingling, or numbness. Heart palpitations or skipped heartbeat can be more severe symptoms of low potassium levels.
It’s possible to fight leg cramps and other issues that stem from low potassium levels by simply increasing your potassium intake. The amount of time it takes to correct low potassium levels depends on how low they are.
Symptoms Of Low Potassium
The only real way to know if your potassium levels are low is to take a blood test. You will get a more accurate reading of your levels via this route. That said, there are a few telltale symptoms of potassium deficiency that you should be aware of. These symptoms include:
- Muscle cramps, twitching, or severe weakness
- Heart palpitations
- Constipation
- Tingling and numbness
If potassium levels are very low, you may need to take a potassium supplement, or get an IV to elevate them back to a normal range. The quickest way to increase potassium levels in emergency situations is via an IV, which should be administered by a professional in a controlled setting. One report found that an IV can raise potassium levels within 20 to 30 minutes. If you have borderline potassium levels after a sweaty workout, you can use various foods to help bring them back up quickly. Continue reading to learn what foods and drinks may help you do that.
Sip An Electrolyte Drink
Electrolyte-rich drinks can help replenish minerals, vitamins, and water lost via sweat or periods of diarrhea and vomiting. Not all electrolyte drinks are high in potassium, though. And you should not simply resort to sugary sports drinks to replenish electrolytes, as the preservatives, dyes, and added sugars do more harm than good. Coconut water, for example, is a great electrolyte-rich beverage, but make sure to buy one that is free of added sugars.
Drink Some Orange Juice
Just as we said previously, the quality of the beverage matters. Many store bought orange juices contain added sugars and preservatives. Go directly to the source by juicing oranges! One cup of orange juice provides nearly 500 milligrams (mg) of potassium, which equates to 11% of the recommended daily intake (RDI). Orange juice may be a convenient way to raise potassium levels, but it tends to be high in sugar. You can also eat oranges to get the same nutrients, plus the fiber that will help the body absorb the natural sugars more slowly. You would need to eat two oranges to get the same amount of potassium as one cup of OJ.
Eat A Banana
This is a classic potassium-rich food, so eat a banana or two next time you are dealing with leg cramps. One medium banana contains 422 mg of potassium, and the potassium in bananas can increase levels within 30 to 60 minutes, per a 2012 health journal. In one study, researchers tested whether eating one or two bananas would increase potassium levels in adult athletes prone to leg cramps. Although there were mild increases in potassium levels in both groups after 30 to 60 minutes, the time it took to increase levels would not benefit an athlete experiencing cramps during competition. To avoid cramps, health experts recommend consuming potassium-rich foods regularly, especially before exercise.
Eat Some Watermelon
Researchers note that one wedge of watermelon has 320 mg of potassium, making it a great choice for raising potassium levels. Watermelon is also a water-rich fruit (91% water), so it helps to enhance your hydration efforts. It is also rich in vitamins A & C, magnesium, and offers some iron and calcium. According to research, eating watermelon after a workout can help replace water, magnesium, and potassium that you lose via sweat. Drinking watermelon juice after a workout has been associated with reduced muscle soreness after 24 hours.
Consider Supplementation
If you consume all of the aforementioned items and your potassium levels remain low, you may want to consider a potassium supplement. Before you start supplementing, consult your healthcare professional to determine whether the supplement is right for you, and to understand proper dosage. The potassium you get via diet and what you supplement should not exceed the RDI, unless directed by your doctor.
