Potassium is one of the body’s most important minerals, present inside every cell at a concentration around 30 times higher than outside it, where it controls nerve impulse transmission, muscle contraction and blood pressure via the sodium-potassium pump. Despite its importance, dietary intake often falls short due to modern lifestyles and fruit and vegetable consumption below recommended levels.

Among the various potassium salts, citrate stands out for superior bioavailability and excellent digestive tolerance. Unlike potassium chloride, which is often bitter and can irritate the stomach, citrate has a neutral taste and dissolves readily in water, delivering a meaningful share of daily potassium needs in just two measuring scoops. Citrate also has a mild alkalising effect, appreciated by athletes and by anyone whose diet, rich in animal protein and refined grains, tends toward metabolic acidity.

At the muscular level, potassium is essential for the contraction and relaxation of muscle fibres, including the heart muscle — a deficiency typically shows up as cramps, unusual fatigue and muscle weakness. At the nervous level, potassium supports the transmission of electrical signals between neurons, backing concentration and reflexes. Its role in blood pressure regulation is well documented, acting as sodium’s counterpart to support renal sodium elimination, and it also plays a part in the body’s acid-base balance. Athletes, older adults and people who sweat heavily have higher potassium needs.

The powder format allows a flexible, personalised dose using the supplied measuring scoop, adjustable to your day’s activity, heat, sweating or diet. It dissolves instantly in water or any other cold drink without significantly altering the taste — easy to fit into your morning routine or after a workout. Each dose requires just 2 measuring scoops (2,500mg of tripotassium citrate) to deliver 875mg of elemental potassium.

Food supplement. Not a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Consult a healthcare professional before use if you have kidney issues, are on medication, or are pregnant or breastfeeding.

What are the signs of low potassium intake?

Unusual fatigue, repeated muscle cramps (particularly at night or after exercise), difficulty concentrating and heart palpitations are classic signs. Athletes, older adults and people on diuretics are particularly exposed. We recommend medical advice to confirm any deficiency.

Does potassium citrate cause digestive discomfort?

Citrate has notably better digestive tolerance than potassium chloride or gluconate. Taken with meals as recommended, it generally causes no discomfort; particularly sensitive individuals can start with half a dose and increase gradually.

Can potassium citrate be combined with magnesium?

Yes, the potassium-magnesium pairing is well documented and works in synergy for muscle, nerve and heart function. Dynveo offers several magnesium forms (bisglycinate, ATA Mg, L-threonate) that combine well with potassium citrate.
