Helps maintain normal blood pressure
Supports normal nervous system function
Supports normal muscle function

Overview

Potassium in a straightforward formula, without a blend of minerals or unnecessary extras. Potassium Citrate focuses on a key electrolyte found inside your cells. Potassium helps establish the electrical potential across cell membranes, allowing nerves to transmit signals and muscles to contract normally.

At the heart of the formula / Potassium Citrate

Thoughtful support. Clear purpose.

01Helps maintain normal blood pressure
02Supports normal nervous system function
03Supports normal muscle function
04Targeted supplementation with a single electrolyte
05A simple formula without a complex mineral blend
06Plant-based capsule suitable for a vegan diet
07Fits a routine focused on sodium–potassium balance

Doctor Life / 01

Potassium Citrate

Made for your daily routine.

Potassium also helps maintain normal blood pressure and plays a role in sodium–potassium balance. Its role in normal blood pressure is recognized in an authorized EU health claim.

We chose potassium citrate, an organic potassium salt studied in randomized human trials. The ingredient list contains potassium citrate and a plant-based pullulan capsule. The label describes the product as vegan, filler-free, and non-GMO.

This single-mineral formula makes it easy to see how much potassium you are taking without adding other vitamins or minerals. Consider it alongside your diet and any other supplements.

Potassium Citrate

Why does potassium matter?

Potassium is the main positively charged ion inside cells. It helps maintain the electrical differences across cell membranes needed for nerve signals and muscle function. It also contributes to fluid balance and the sodium–potassium balance involved in blood pressure regulation.

What does research say about Potassium Citrate?

Clinical research has examined potassium intake and blood pressure. A six-week randomized potassium citrate trial found reductions in mean, systolic, and diastolic blood pressure compared with placebo. A separate study of a moderate potassium intake in healthy volunteers also found blood pressure differences. EFSA recognizes potassium’s roles in normal blood pressure, muscle function, and nervous system function. These studies do not establish the effects of this finished product or make it a treatment for hypertension.

Science & sources

Understand the formula.

Maintaining normal blood pressure is one of potassium's best-documented roles. Clinical studies also examine the effects of increasing potassium intake. These publications include a direct study of potassium citrate, a low-dose potassium study in healthy adults, and the EFSA opinion underlying authorized European health claims.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01The effect of a dietary supplement of potassium chloride or potassium citrate on blood pressure in predominantly normotensive volunteers

Alessandro Braschi, Donald J. Naismith

British Journal of Nutrition (2008), 99(6), 1284-1292. DOI: 10.1017/S0007114507864853; PMID: 18053306.

This six-week randomized, double-blind, placebo-controlled study examined 30 mmol of potassium daily as potassium citrate in healthy adults, most of whom had normal blood pressure. Compared with placebo, mean arterial pressure fell by 5.22 mmHg, systolic pressure by 6.69 mmHg, and diastolic pressure by 4.26 mmHg. The study is relevant to this formula because it examined potassium citrate specifically.

02The effect of low-dose potassium supplementation on blood pressure in apparently healthy volunteers

Donald J. Naismith, Alessandro Braschi

British Journal of Nutrition (2003), 90(1), 53-60. DOI: 10.1079/BJN2003861; PMID: 12844375.

In a double-blind, placebo-controlled study, 59 healthy volunteers received 24 mmol of potassium daily, approximately 938 mg, for six weeks. In the supplemented group, mean arterial pressure fell by 7.01 mmHg, systolic pressure by 7.60 mmHg, and diastolic pressure by 6.46 mmHg. The study used a moderate amount of potassium, closer to everyday supplementation than the multigram doses used in some earlier research.

03Scientific Opinion on the substantiation of health claims related to potassium and maintenance of normal muscular and neurological function and maintenance of normal blood pressure

EFSA Panel on Dietetic Products, Nutrition and Allergies (NDA)

EFSA Journal (2010), 8(2), 1469. DOI: 10.2903/j.efsa.2010.1469.

EFSA confirmed a cause-and-effect relationship between potassium intake and three functions: normal muscle function, normal nervous system function, and maintenance of normal blood pressure. These well-documented roles provide the main basis for daily potassium supplementation.

FAQ / Potassium Citrate

Good questions. Clear answers.

Talk to us ↗

Does 1,900 mg of potassium citrate mean 1,900 mg of potassium?

No. The 1,900 mg figure is the weight of the complete potassium citrate compound. It provides 720 mg of elemental potassium, or 36% NRV. Compare elemental potassium amounts across products, rather than the weight of the mineral salt.

Why supplement potassium when it is found in food?

Potassium occurs in many foods, including vegetables, fruits, potatoes, seeds, and dairy products. EFSA sets an adequate adult intake of 3,500 mg daily. Supplements do not replace food and should be considered in the context of diet and individual needs.

Is potassium citrate better than potassium chloride?

Neither form is inherently best for everyone. Potassium citrate has been studied directly in humans: one six-week randomized trial used 30 mmol of potassium as citrate and found blood pressure changes compared with placebo. This does not establish superiority over potassium chloride.

Is potassium only relevant to blood pressure?

No. EFSA recognizes three roles: helping maintain normal blood pressure and supporting normal nervous system and muscle function. Potassium is relevant to all three areas.

Is Potassium Citrate suitable for physically active people?

Potassium is an electrolyte needed for normal muscle and nervous system function. Whether supplementation is useful depends on diet, sweat losses, and overall electrolyte intake. This single-mineral formula provides potassium without additional minerals; individual suitability still matters.

Can I take potassium with blood pressure medication?

Consult your doctor first. Some medicines, especially ACE inhibitors, angiotensin receptor blockers, and potassium-sparing diuretics, can reduce potassium excretion and increase the risk of high blood potassium. Medical advice is also needed if you have kidney disease.

Why does kidney function matter when taking potassium?

The kidneys regulate potassium levels. Impaired kidney function can reduce its excretion, and excess potassium can cause hyperkalemia. If you have kidney disease, do not increase potassium supplements without medical advice.
