How are we different?

With 35% pure potassium, our potassium citrate delivers a high dose of plant-based potassium derived from fermentation, making it unique in a market saturated with synthetic products. The raw ingredient for our potassium citrate is 100% non-GMO corn. Microbes metabolise the corn into potassium citrate that, as a final product, is free from corn, histamine, and yeast. Our potassium citrate is also completely vegan, well-tolerated, and free from chemical residues. Auxiliary materials are avoided to the greatest extent possible and fully disclosed.

For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass jars.

Potassium is the third most common mineral in the body and an essential electrolyte. Sports as well as daily stress can increase bodily requirements for minerals such as potassium. Approximately 98% of all potassium in the body can be found inside the cells while its major counterpart, sodium, is mostly concentrated outside of cells. A balanced ratio of these minerals lays an important foundation for a number of bodily reactions including enzymatic metabolic processes. Modern diets, which are often heavy in salt, can easily bring this system out of balance so that the body has insufficient plant-based potassium to counterbalance an excess of sodium. In fact, too much sodium can even lead to the expulsion of potassium from the body via the kidneys. Since potassium cannot be stored in the body, daily intake is required to maintain balance within the body.

Potassium citrate is the potassium salt of citric acid (citrate), a naturally occurring intermediate product in energy metabolism. Citrate is metabolised in the citric acid cycle and is thus a central component of energy production in cells. Neither citric acid nor its salt citrate triggers allergic reactions in people who are allergic to oranges and citrus fruits. Due to their weakly alkaline pH, citrates are readily available and well-tolerated, without neutralising stomach acid or alkalinising the intestinal environment.

Health Benefits of Potassium According to the European Food Safety Authority (EFSA)

Potassium contributes to:

  • Normal functioning of the nervous system
  • Normal muscle function
  • The maintenance of normal blood pressure


Recommended Dosage

Take 2 capsules (400mg elemental potassium per capsule) daily with 200ml water, ideally spread throughout the day.

Daily Requirements

Sodium-rich diets can contribute to a potassium deficiency. The recommended daily potassium intake has been increased in recent years from 2,000mg to 4,000mg.


Caution is necessary in cases of limited potassium excretion as a result of kidney disease or certain medications (such as diuretics, antihypertensives, and painkillers). Even slight fluctuations in (extracellular) blood potassium levels can lead to serious neuromuscular and muscular disorders.

Food Supplement

Do not exceed the recommended dose. Food supplements cannot replace a balanced and varied diet. Keep out of reach of children.


Store in a cool, dry place away from direct sunlight and heat.
