While supplements can help you reach your dietary goals, it’s best to load up on vitamins and minerals from fresh foods, such as vegetables, fruits, and whole grains.
It’s a good idea to know what foods are high in magnesium and potassium.
The best sources of both magnesium and potassium are whole grains, leafy greens, and foods high in healthy fats. Such foods are not only rich in these two minerals but also other crucial vitamins and nutrients that help you stay healthy. As a result, it’s a good idea to add a couple of these foods to your diet.
A healthy adult should consume around 4700mg of potassium and between 310-420mg of magnesium, depending on your age and gender.
Since many people don’t take in enough of these minerals, it’s a good idea to familiarize yourself with foods high in magnesium and potassium and include them in your diet.

What do magnesium and potassium do in your body?
Magnesium is involved in hundreds of biochemical reactions in your body, including energy creation, protein formation, gene maintenance, and muscle contractions.
Consuming a good amount of magnesium may also boost exercise performance and your immune system. Unfortunately, studies show that nearly 50% of the population takes in too little of this mineral.
So, since these are all very important processes, it’s vital to consume high-magnesium foods.
Potassium helps regulate fluid balance, muscle contractions, and nerve signals. A diet high in potassium also helps reduce blood pressure and prevent water retention by stopping kidney stones from forming.
What’s more, potassium may protect your body against stroke, both by lowering blood pressure and ensuring good fluid balance. The lack of potassium in your diet might lead to an irregular heartbeat and muscle weakness, so it should be avoided.
Together, magnesium and potassium are responsible for regulating blood pressure and keeping it at a stable level.
Because of that, they also help manage hypertension in adults, especially when they’re absorbed from fresh, natural foods, such as vegetables, fruits, and whole grains. As a result, consuming foods that are rich in both of these nutrients at the same time is very beneficial.
Is it bad to consume too many foods high in potassium and magnesium?
Depending on your dietary requirements, you may need to consume foods that are lower in potassium. This is especially true if you suffer from renal issues as your kidneys may not be able to remove excess amounts of this mineral.
In that case, you can still consume high-magnesium foods since it’s an essential mineral, and it’s nearly impossible to take in too much. But you might need to be careful about high-potassium foods and listen to the recommendations of your doctor.
A diet high in magnesium and potassium is incredibly beneficial for maintaining healthy blood pressure. These minerals also help regulate blood sugar levels and even create protein, making them a wonderful addition to a healthy, balanced diet.
