Powerday is a food supplement based on Potassium Bicarbonate. Potassium contributes to the normal functioning of the nervous system, normal muscle function and the maintenance of normal blood pressure.
Potassium Bicarbonate is naturally occurring and has an alkaline pH. International nutritional guidelines indicate that potassium intake in the general population is often below recommended levels, while sodium intake is generally higher.
Distinctive product features
- Potassium Bicarbonate, useful for regulating the Sodium:Potassium ratio.
- Natural Xylitol extracted from birch bark, considered to be of superior quality due to its purity, as natural extraction does not require chemical processes, which preserves its beneficial nutritional characteristics.
- Measuring spoon to simplify the use of the correct daily amount of powder to dissolve in water.
- 100% plant-based container (bioplastic)
Powerday, a high-quality natural micronized potassium bicarbonate supplement
To make our supplement even easier to use, we provide a measuring spoon to help you measure the right daily amount of powder to dissolve in water.
Not only is it formulated with micronized potassium bicarbonate for rapid assimilation, but it also has a delicious taste thanks to the addition of natural xylitol and a measuring spoon for precise dosing.
Frequently asked questions:
1. What is Powerday and what does it contain?
Powerday is a food supplement based on Potassium Bicarbonate and Xylitol from fermentation, in equal proportions. The recommended daily dose is 9g and provides 1729 mg of potassium - 86% of the daily nutritional reference value. It is free of added sugars, artificial flavors, and colorings.
2. Why did you choose Potassium Bicarbonate and not other forms?
Among the available forms of potassium, Potassium Bicarbonate has a distinct technical characteristic: in aqueous solution, it has a weakly alkaline pH, unlike Potassium Chloride (KCl), which is neutral. It contains about 39% elemental potassium by weight and dissolves easily in water. It is the form we chose to combine purity, bioavailability, and a chemical profile consistent with the philosophy of the Swiss Natural Med line.
3. How does potassium support the nervous system?
Potassium is the main mineral found inside the cells of our body. The nervous system uses potassium to generate and transmit nerve impulses: every time a neuron transmits a signal, potassium moves in and out of the cell to restore the membrane potential. Without an adequate supply of potassium, the speed and precision of this process are compromised.
Potassium contributes to the normal functioning of the nervous system.
4. What is the connection between potassium and muscles?
Just as in neurons, in muscle cells, potassium also regulates the membrane potential that allows contraction. During every muscle contraction, potassium moves between the inside and outside of the cell: the rapid restoration of this balance is what allows the muscle to respond to the next stimulus. An adequate intake of potassium is therefore relevant both in daily life and during physical activity with sweating.
Potassium contributes to normal muscle function.
5. How does potassium affect blood pressure?
Potassium and sodium work in opposite ways in our body: while an excess of sodium tends to raise blood pressure, an adequate intake of potassium promotes the elimination of sodium through the kidneys, thus contributing to the maintenance of normal values. Recent research, including a review published in Nature Reviews Nephrology in 2026 (Hoorn et al.), confirms that diets rich in potassium promote natriuresis - i.e., the kidneys' ability to eliminate sodium - with documented positive effects on arterial blood pressure.
Potassium contributes to the maintenance of normal blood pressure.
6. What is Xylitol from fermentation?
Xylitol is a natural sweetener present in small quantities in strawberries, plums, and cauliflower. The xylitol used in Powerday is produced by fermentation: selected microorganisms transform xylose - a vegetable sugar - into xylitol enzymatically, without resorting to the high-pressure chemical hydrogenation processes typical of conventional production. We use a more sustainable process consistent with our philosophy of clean production. Each dose of Powerday provides 4.5g of xylitol.
7. Is xylitol good for teeth?
Yes, and that's one of the reasons we chose xylitol as the second ingredient in Powerday. The bacteria responsible for tooth decay - primarily Streptococcus mutans - cannot ferment xylitol as they do with common sugar. This means that xylitol does not produce the acids that demineralize tooth enamel. A review published in Frontiers in Cellular and Infection Microbiology in 2026 (Katrak et al., University of Florida) describes xylitol among the agents that actively interfere with the metabolism of cariogenic bacteria, contributing to the maintenance of a balanced oral biofilm.
The consumption of Powerday containing xylitol instead of sugar helps maintain tooth mineralization.
8. Does Powerday contain sugar? Does it affect blood sugar?
No, Powerday contains no added sugars. Xylitol has a very low glycemic index (about 7, compared to glucose = 100) and does not stimulate insulin secretion to the extent that sucrose does. This is a feature particularly appreciated by those who monitor their glycemic response - including people who exercise or follow low glycemic index diets.
9. Why do many people not get enough potassium?
The main dietary sources of potassium are fresh fruit, leafy vegetables, legumes, and potatoes - foods that in modern diets, often rich in packaged and processed products, tend to be underrepresented. A meta-analysis published in 2025 in F1000Research (Farapti et al.) which analyzed data from over 62,000 people worldwide found that the ratio of sodium to potassium in the population's diet is on average much more unbalanced towards sodium than recommended by international nutritional guidelines. With 1729 mg of potassium per daily dose, Powerday covers 86% of the nutritional reference value.
10. Is Powerday suitable for athletes?
Yes. Potassium is one of the electrolytes lost through sweating during physical activity. During intense exercise, muscles release potassium into the space between cells: restoring this balance is part of the normal muscle recovery process. Powerday, with its high potassium intake (86% NRV per dose) and complete absence of sugars, is suitable for those who want to support normal muscle function without introducing added sugars before, during, or after training.
Potassium contributes to normal muscle function.
11. Can excessive consumption of xylitol have laxative effects?
Like all polyalcohols, xylitol is only partially absorbed in the small intestine: at very high doses, the unabsorbed portion can have an osmotic laxative effect. The dose of Powerday provides 4.5g of xylitol per day - an amount well below the thresholds that have been associated with this effect in clinical studies (generally over 40-50g per day).
12. Is Powerday suitable for vegetarians and vegans?
Yes. Potassium Bicarbonate is an inorganic compound. Xylitol from fermentation is produced from plant substrates. Neither ingredient contains components of animal origin. Powerday is fully compatible with vegetarian and vegan diets and does not contain any major food allergens.
13. Can I take Powerday with other Swiss Natural Med supplements?
Powerday integrates well with other products in the line. Those already using Ultra Amino Veg - which provides 1280 mg of potassium per dose - should note that combining the two products on the same day brings the total potassium intake to approximately 3000 mg, in line with the adequate intake values indicated by the EFSA for the adult population (3500 mg/day).
If you are taking medication for blood pressure, kidney function, or diuretics, consult your doctor before starting any potassium supplementation.
14. Who should consult a doctor before using Powerday?
Powerday is a safe food supplement for healthy adults. We recommend consulting your doctor before use if: you have kidney disease or reduced kidney function; you are taking ACE inhibitors, sartans, potassium-sparing diuretics, or anti-inflammatory drugs (NSAIDs); you are pregnant or breastfeeding. As with all supplements, keep it out of reach of children and do not exceed the recommended daily dose.
15. How should Powerday be used and what is the recommended dose?
The recommended daily dose is 9g, to be taken according to the instructions on the label, preferably dissolved in 1-1.5 liters of water to be drunk throughout the day. Food supplements do not replace a varied and balanced diet and a healthy lifestyle.
