Potassium is important
to keep blood pressure under control

How does potassium work?

Together with sodium chloride, potassium works to regulate the water balance of the body and to soothe transmission of nerve impulses. Sodium and potassium are both necessary to keep your blood pressure under control.

Potassium is also important for the conduction of nerve impulses, muscle contraction and energy metabolism in muscles.

Potassium in the diet

The potassium is present in almost all foods. Potatoes, bread, dairy products, meat and vegetables are important sources of potassium.

If potatoes and vegetables are cooked with plenty of water, some of the content of potassium is lost. Therefore take care not to use more water than necessary when cooking.

Lack of potassium

A deficiency of potassium is rare, but may still occur in the event of excessive losses of this mineral due to prolonged diarrhea or vomiting. This deficiency can also be caused by the use of laxatives or diuretics.

Excess potassium

There is no fixed safe upper limit for the intake of potassium. As a rule, in fact, our body is able to maintain the correct levels of potassium through kidney function. If the availability of potassium in the body is reduced, however, the excretion of this mineral will be minimal. About 90% of excess potassium is excreted in the urine and the remainder is instead removed from the body through the faeces. The excretion of potassium by the kidneys is strongly influenced by the amount of sodium in the body. In the face of a substantial excretion of potassium, sodium excretion will be reduced and vice versa. When sweating we only lose a small amount of potassium.

There are no guidelines nor a safe upper limit for the intake of potassium. To regulate blood pressure in the correct way, however, it is suggested that a significant contribution of potassium in combination with a reduced content of sodium in the diet can help. The amount of potassium recommended daily in adults is between 3.1 and 3.5 g.

Potassium supplements

Usually the intake of potassium supplied to the body through diet is adequate. For this reason FitForMe decided not to add potassium to their products.
