Now Foods is a name that carries weight in the supplement world, and this potassium citrate formulation lives up to it. The 99mg elemental potassium per capsule is the gold standard dose, and the 360-capsule count means you get nearly a year’s supply if you take one daily. Users consistently report that it nails the two most common use cases: stopping nocturnal leg cramps and supporting steady heart rhythm. One review noted that consistent use for about two weeks was the sweet spot before feeling a real difference in muscle recovery.

The citrate form here is well-absorbed and gentle enough to take on an empty stomach, though pairing it with a meal reduces any mild gastric sensitivity. Now Foods packages this in a vegetarian capsule with no soy, gluten, or dairy, making it a clean option for anyone with multiple dietary restrictions. The NPA A-rated GMP certification means the manufacturing process is regularly audited for potency and stability — a level of quality assurance that matters when you are relying on the supplement for something as critical as heart function or pH balance.

Taking this at dinner or before bed aligns with the body’s natural electrolyte dip during sleep, which is exactly when those middle-of-the-night cramps hit. For daytime use, taking it with lunch helps maintain electrolyte levels through the afternoon slump. It is not the cheapest option upfront, but the cost per serving is very low, making it a smart long-term investment for daily use.

BulkSupplements has built a reputation on stripping away the fluff and delivering pure, single-ingredient supplements at volume. This potassium citrate capsule comes in a 500-count bottle with the standard 99mg elemental dose per capsule. The standout feedback here comes from users dealing with kidney stones — multiple verified reviews mention that the product helped break down existing stones faster than expected. That makes sense, given that potassium citrate is clinically prescribed for calcium oxalate stone prevention, and the high citrate load in this supplement likely supports urinary alkalinization.

The capsules are small and easy to swallow, with no taste or aftertaste. BulkSupplements manufactures this in a cGMP-compliant facility, so you get production quality without paying for fancy branding. The packaging is straightforward — a white bottle with a simple label — but the focus is on what is inside. One reviewer noted that their doctor was happy with the choice, which is a reassuring data point for anyone managing a condition like hypocitraturia.

Timing-wise, splitting the dose across two meals works well here because the bottle lasts so long that you will not mind using two capsules a day. For kidney stone prevention, taking one capsule with breakfast and one with dinner keeps citrate levels elevated throughout the day. For general electrolyte support, a single capsule with lunch is sufficient. The absence of magnesium in the formula is worth noting if you also need magnesium — you will need a separate supplement for that.

Captek takes a different approach by labeling the compound weight rather than just the elemental potassium. Two capsules deliver 1000mg of potassium citrate, which translates to roughly 200mg of elemental potassium per serving. This makes it a good choice for people who need a higher potassium intake without swallowing four separate capsules. The serving size of two small capsules (0.82 inches each) is manageable, and the company specifically formulates it to be gentle on the stomach — a claim backed by user feedback that mentions no bloating or cramping.

The price point per bottle is slightly above the others, but the 45-day supply (at two capsules per day) is reasonable for a mid-range product. Captek manufactures this in a GMP-certified facility in the USA, using vegan, non-GMO, and gluten-free ingredients. One review pointed out that it is less expensive than a prescription equivalent, which is a meaningful comparison for anyone currently paying for a doctor-prescribed potassium citrate.

Because the serving size is two capsules, timing is flexible — take both at the same meal or split them between lunch and dinner. The higher dose per serving works well for people who want to take it specifically before bed to combat nocturnal leg cramps without needing a second dose. Just be careful not to exceed the recommended serving unless your doctor advises otherwise, as potassium overload is a real risk for those with compromised kidney function.

Nutricost has a loyal following for good reason — they deliver consistent quality at a fair price, and this potassium citrate capsule is a textbook example. One user review stood out as a perfect case study for timing: the reviewer specifically takes this at bedtime and reports that it completely eliminated nightly leg cramps and charley horses. They even tested it by stopping for two nights, and the cramps came right back. That kind of direct A/B testing is rare in supplement feedback and strongly suggests that taking potassium citrate close to sleep is the optimal window for people prone to nocturnal leg cramps.

Each capsule provides 99mg of elemental potassium in a small, flavorless pill. The 240-count bottle gives you exactly 240 servings at one per day, so you are looking at an eight-month supply. The capsules are made in a GMP-compliant facility and are free of gluten and GMOs. A few users mentioned the seal on the bottle top could be more secure, but that is a packaging issue rather than a quality concern. The product itself is consistent and reliable.

Beyond leg cramps, Nutricost works well for general electrolyte replenishment after exercise or during hot weather. Taking it with dinner or an hour before bed appears to be the sweet spot based on community feedback. If you are using it during the day, pairing it with a meal helps with absorption and reduces the chance of any gastric discomfort.

NatureBell positions itself as a high-volume, low-cost entry point, and for the price, the 500-capsule bottle is hard to beat. Each capsule contains 99mg of elemental potassium in the citrate form, and the company emphasizes that it is non-GMO, gluten-free, and made without common allergens like wheat, soy, and dairy. Third-party lab testing adds a layer of trust that is not always present at this price tier. Users describe the capsules as easy to swallow with no aftertaste, and the one-capsule-per-day serving size means a single bottle stretches to nearly a year and a half.

The feedback is positive but leans heavily on the value angle — people appreciate the quantity for the cost, and several mention that a physician recommended potassium citrate over gluconate for kidney-related concerns. That is an interesting point because the citrate form’s ability to alkalinize urine makes it preferable for certain kidney conditions. NatureBell is a newer player (product first available in August 2024), so long-term consistency data is thinner than for brands like Now Foods, but the early reviews are uniformly strong.

For timing, the low dose per capsule (99mg) makes it ideal for a single daily intake with a meal. Because the bottle is so large, it is also a great option for families or couples who both take potassium. Just store it in a cool, dry place to keep the capsules from sticking together over the many months they will last. If you are new to potassium supplementation, this is a risk-free way to start without a big financial commitment.
