When someone is diagnosed with high blood pressure, the same thing usually happens. First, fear runs through the body, and then we proceed to search on Saint Google or our new best friend ChatGPT and look for natural solutions, and there the magic word appears: potassium. Like a lifesaver. But is potassium really that good for blood pressure?
There are now several studies that say potassium helps, but only in certain cases. Taking it without knowing what your levels are or how your kidneys work can be dangerous.
What potassium does in the body
Potassium is a basic mineral that makes nerves work, keeps body fluids in balance, and allows muscles to function properly (that is why you see all the gym bros eating bananas).
When it comes to the heart and blood pressure, it helps relax blood vessels, meaning it allows blood to flow with less resistance.
It does not lower blood pressure in all cases
If your potassium levels are already normal, taking more will not lower your blood pressure. Specialists explain that the effect is mainly noticeable when there is a deficiency. In those cases, correcting it can help.
When potassium can be helpful
Potassium can be useful if hypokalemia exists (low potassium levels), and the main reasons are usually these:
- Diets low in fruits and vegetables
- Use of diuretics
- Sweating a lot on a regular basis
- Prolonged vomiting or diarrhea
In those situations, increasing potassium, but in a controlled way, can help the functioning of your cardiovascular system.
What about supplements?
Be careful, because we tend to think supplements do nothing, and any excess can cause heart rhythm disturbances.
The kidneys
The body eliminates potassium mainly through urine. If the kidneys do not work well, the mineral accumulates and kidney colic and other diseases begin to appear.
People with kidney disease, who take certain medications, or who are on dialysis should not take potassium without medical supervision!!!
What if I need to add potassium to my diet?
The best thing you can do is eat well. You will not need any supplements, and when you follow a balanced diet, potassium is supplied to your body in a reasonable and safe way.
- Legumes
- Leafy green vegetables
- Potatoes
- Bananas
- Pumpkin
- Dried fruits
How much potassium does the body need?
The general recommendation is around 4,700 milligrams per day for adults. Supplements, on the other hand, concentrate high doses in very little space. That is why they should only be used if a doctor indicates it and with blood tests involved.
A myth worth debunking
Potassium does not replace hypertension medications. It is not a miracle cure or a quick solution, so be very careful if you decide to self diagnose.
Maybe, to improve your blood pressure issues, you can move more, reduce salt in your food, and sleep more!
What if I want to take supplements?
First, you will have to talk to your doctor. If you need to correct some imbalance in your body, they will likely prescribe it and tell you how much to take.
The best decision for your heart
If you have high blood pressure and the idea of taking potassium is on your mind, the first step is to talk to your doctor so they can run tests and explain how to improve that deficiency, if it exists. If not, it is better to adjust your diet, which is much safer than asking ChatGPT!
