The active ingredient is potassium citrate, listed as 99 mg per capsule. The product uses vegetarian capsules, which can be helpful if you avoid gelatin or prefer plant-based capsule materials.
Why potassium citrate matters
Understanding why a specific form of potassium is used helps you make a more informed choice. Potassium citrate is often chosen because of its absorption profile and its potential to support acid-base balance.
Potassium itself is an essential mineral your body needs for maintaining whole-body and cellular fluid levels, supporting acid-base balance, and enabling healthy muscle contractions, heart function, and nerve impulse transmission. The citrate form is generally considered well absorbed and may be gentler on the stomach compared with some other potassium salts.

How potassium works in your body
This explains the physiological roles that potassium supports and why supplementing might matter if your intake is low or you have increased losses. You’ll get a practical perspective on the most important functions.
Potassium helps regulate fluid balance inside and outside your cells, ensuring proper cellular hydration and electrolyte equilibrium. It’s also a key player in nerve impulse conduction and muscle contractions, including cardiac muscle, which is why normal potassium levels are critical for heart rhythm and function.
Benefits you can expect
If you’re wondering what benefits this supplement could provide, this section lists likely outcomes based on the nutrient’s known functions. Benefits will vary based on your diet, health status, and whether you actually have low potassium.
Common reasons people take potassium supplements include supporting normal electrolyte balance after heavy sweating, helping maintain normal acid-base (pH) balance, reducing the likelihood of muscle cramps from low potassium, and supporting healthy heart function when dietary intake is insufficient. Keep in mind that benefits are most likely when the supplement corrects an actual deficiency or increased requirement.
Dosage and how to take it
Correct dosing and timing influence both efficacy and safety, so you’ll want to follow recommended guidelines and tailor them to your needs. This section clarifies practical points on how to take the product.
NOW Foods recommends 1 capsule 1 to 5 times daily, preferably with food. Taking potassium with food can reduce the chance of gastrointestinal upset and improves tolerability; if you need higher daily potassium, you should space doses throughout the day rather than taking many at once.

Bioavailability and absorption
You’ll learn why the citrate form matters and how that affects what your body actually gets. Absorption characteristics can affect whether a supplement is effective and how your stomach tolerates it.
Potassium citrate is described as a well absorbed and highly bioavailable form of potassium, meaning a significant portion is likely available to your system after oral intake. Citrate can also serve as an alkalinizing agent, which contributes to the product’s claim to support normal pH, but individual responses can vary.
Safety and potential side effects
Safety is a top priority when adding minerals to your regimen, so this section outlines common side effects and the situations where you should be cautious. You’ll get a sense of what to watch for and when to pause supplementation.
Typical mild side effects might include gastrointestinal discomfort, nausea, or diarrhea if you take higher doses or take capsules on an empty stomach. More seriously, excess potassium (hyperkalemia) can cause muscle weakness, irregular heartbeat, and other cardiac issues, so you should consult a healthcare provider if you have kidney problems, heart disease, or if you’re taking medications that affect potassium levels.
Drug interactions and contraindications
If you use prescription medications, check interactions before starting a potassium supplement. This section highlights the main drug categories that frequently interact with potassium.
Drugs that can raise potassium levels — for example, ACE inhibitors (like lisinopril), angiotensin receptor blockers (ARBs like losartan), potassium-sparing diuretics (like spironolactone or amiloride), and some NSAIDs — can increase the risk of hyperkalemia when combined with potassium supplements. If you’re on any medication that affects kidney function or potassium handling, you should discuss supplementation with your healthcare provider first.

Who should consider this supplement
This helps you decide whether you’re in the group that could benefit from potassium citrate. It outlines practical scenarios where supplementation may be warranted.
You might consider this supplement if you have a documented low potassium level, you lose a lot of electrolytes through heavy sweating (frequent intense exercise or work outdoors), or if your diet is low in potassium-rich foods (like fruits, vegetables, and legumes). People on certain diuretics or those recovering from conditions that cause significant fluid loss may also find supplementation helpful under medical supervision.
Who should avoid or use potassium with caution
There are important safety exclusions that you need to pay attention to before starting a potassium supplement. This section lists the main groups for whom potassium supplementation could pose risks.
Avoid or use potassium supplements cautiously if you have chronic kidney disease, adrenal insufficiency, untreated Addison’s disease, severe dehydration, or if you’re taking medications that increase potassium. Pregnant or breastfeeding individuals should consult their healthcare provider before starting any supplement, and children should only take them under medical guidance.

Real-world effectiveness and customer experience
Customer reports and real-world use provide practical insight into what you might actually notice when taking the supplement. This section synthesizes common experiences reported by users.
Many users report improved management of muscle cramping and better recovery after heavy workouts or long periods of sweating when they include potassium supplements alongside hydration and electrolytes. Others appreciate the convenience of a capsule you can take with meals, though results can depend heavily on baseline potassium status and whether dietary sources are adequate.
Comparing potassium forms and alternatives
This side-by-side look helps you understand how potassium citrate stacks up against other forms and what trade-offs exist. Use these comparisons to align your choice with your priorities (absorption, tolerability, cost).
- Potassium citrate: Often praised for good absorption and potential alkalinizing effects, which can support pH balance. It may be gentler on the stomach for some people.
- Potassium chloride: Frequently used to correct low potassium; it provides potassium without citrate’s alkalinizing effect and may be less expensive but can cause more gastrointestinal irritation in sensitive individuals.
- Potassium gluconate: Another common form; tends to be gentle and well tolerated but provides varying elemental potassium amounts depending on formulation.
- Whole foods (bananas, potatoes, spinach, beans): The safest source for most people and includes fiber and other nutrients, but you may need concentrated supplements if you have higher needs or losses.
