Muscles, in everyday life
Walking, climbing stairs and training all require your muscles to contract and respond to stimuli. Potassium contributes to normal muscle function, taking part in the mechanisms that make these contractions possible.





Micronised potassium bicarbonate to dissolve in water. Neutral taste, no added sugars, with 1729 mg of potassium per dose.
300 g about 33 days
For those who walk, train or spend many hours on the move and want to support the normal function of their muscles. Potassium also plays a part in the transmission of nerve signals, which are involved in the movements you make every day.
Powerday suits those who prefer a supplement they can drink and want to avoid added sugars: you prepare the water in the morning with the scoop provided and drink it gradually during the morning. The Neutral version is sweetened with xylitol and contains no added flavourings.
From everyday steps to training, potassium plays a part in essential functions of the body. Powerday provides 1729 mg per dose, equal to 86% of the nutrient reference value.

It is advisable to seek medical advice regarding potassium intake. Taking certain medicines at the same time may interfere with potassium retention in the body. Consult your doctor before use if you have kidney disease, are pregnant or breastfeeding, or take ACE inhibitors, sartans, potassium-sparing diuretics or anti-inflammatory NSAIDs.
Micronisation reduces the size of the powder particles. Potassium bicarbonate dissolves in water and is the source of the mineral in the formula. Each 9 g scoop contains 4.43 g of potassium bicarbonate, which provides 1729 mg of potassium.
The sweetness comes from xylitol, obtained by fermentation from a plant-based raw material. Powerday Neutral has no added sugars, no colourings and no added flavourings.
The scoop helps you prepare the daily dose. The 300 g jar is made of plant-based bioplastic, in line with Swiss Natural Med’s choice of materials.

A powder to dissolve, three ingredients and a scoop to prepare the daily dose.

One 9 g scoop provides 86% of the nutrient reference value for an average adult. The potassium is supplied in the form of micronised bicarbonate.
Xylitol from fermentation gives the drink its sweetness without adding sugar. The Neutral version contains no added flavourings.
Dissolve one scoop in at least one litre of water and drink it during the morning. The 300 g pack includes the measuring scoop.
One 9 g scoop provides 1729 mg of potassium, equal to 86% of the nutrient reference value for an average adult.
The dose contains 4.43 g of potassium bicarbonate: this is the amount of the compound, while 1729 mg is the amount of the mineral it provides.
It is a water-soluble form of potassium. Swiss Natural Med uses it in micronised form, that is, processed into fine particles, for preparing the drink.
In solution it has a slightly alkaline pH: this is a characteristic of the compound.
Yes, it can be included in the diet of an adult who is physically active. Potassium contributes to normal muscle function and is involved in the mechanisms of contraction.
Follow the directions: one scoop a day in at least one litre of water, to drink during the morning.
The label says to take it during the morning. Dissolve one 9 g scoop in at least one litre of water and drink it gradually. Do not exceed the recommended daily dose.
It contains no added flavourings. Xylitol gives the drink a sweet note: neutral means unflavoured, not unsweetened.
Powerday Orange also contains natural orange flavouring. The two versions have the same 300 g pack size, the same daily dose and the same potassium content.
It is a sweetener from the polyol family. The xylitol used in Powerday is obtained by converting a sugar of plant origin, xylose, through a fermentation process.
It is the ingredient that gives the drink its sweetness, without adding sugar.
Powerday has no added sugars and is sweetened with xylitol. Xylitol is a polyol, different from ordinary sugar.
If you follow a prescribed diet to control your blood sugar, discuss with the professional who looks after you how to include it in your diet.
Xylitol provides sweetness without being used by tooth decay bacteria the way ordinary sugar is. Replacing sugar with xylitol thus avoids the production of the acids produced when bacteria ferment sugar.
It is one of the reasons why Swiss Natural Med chose it for Powerday.
Yes: as stated on the label, excessive consumption of polyols may produce laxative effects. Tolerance varies from person to person; keep to the recommended dose and also take into account any other foods with polyols you eat during the day.
Fruit, vegetables, pulses and potatoes are among the dietary sources of potassium. A varied diet remains the starting point; Powerday lets you supplement your intake of this mineral with a defined amount per dose.
Consider your total potassium intake if you already use other supplements that contain it. Regarding potassium intake, the label advises seeking medical advice.
If you take blood pressure medicines, diuretics or medicines that affect kidney function, consult your doctor or pharmacist before starting.
In particular, anyone with kidney disease or reduced kidney function, anyone taking ACE inhibitors, sartans, potassium-sparing diuretics or anti-inflammatory NSAIDs, and women who are pregnant or breastfeeding. Not recommended for children.
You will find the full warnings in the How to use section.
