HelloPharmacist Scorecard of Potassium Citrate by SuperiorLabs

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: potassium. The supplement also includes two inactive ingredients — cellulose and rice husk — which serve as a capsule filler and binder.

Does it work?

Couldn't assess
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: kidney health and normal urine acidity.
  • We looked for evidence on: kidney function, urinary pH, uric acid metabolism.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The product facts do not include an effectiveness rating for potassium in this form or for a specific health purpose, so we cannot tell you from our data whether it works for the reason you're considering it.

The evidence, ingredient by ingredient Potassium

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Potassium from food is safe in normal amounts, but supplements carry real risks, especially if you have kidney disease — they can cause dangerously high blood potassium levels. The most common side effects from oral potassium are mild and digestive: abdominal pain, belching, diarrhea, gas, nausea, and vomiting.

Rare but serious effects include heart rhythm problems, low blood pressure, and confusion — all tied to high potassium levels. For pregnancy and breastfeeding: dietary potassium is appropriate, but if you're pregnant or nursing, talk with your doctor or pharmacist before taking a potassium supplement.

The data rates potassium as likely safe in pregnancy and lactation, but supplements need individualized medical guidance.

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Potassium.
  • The most serious interaction on file is rated Moderate.
  • For scale: 62 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, ask your pharmacist to check your medications against potassium-sparing diuretics (Moderate severity), ACE inhibitors (Moderate severity), and ARBs (Moderate severity). Altogether, these interactions span 62 individual medications.

If you take any of these drug types, do not use this supplement without clearance from your doctor or pharmacist.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Potassium supplements work best for people whose doctors have confirmed low blood potassium and cleared them for supplementation. If you take blood pressure medications — especially diuretics, ACE inhibitors, or ARBs — check with your pharmacist first; these drugs and potassium supplements together can be risky.

Never start a potassium supplement on your own, especially if you have kidney disease.

Potassium3 drug types · 62 drugs

Ace Inhibitors (Aceis)

Using ACEIs with high doses of potassium increases the risk of hyperkalemia.
ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Angiotensin Receptor Blockers (Arbs)

Using ARBs with high doses of potassium increases the risk of hyperkalemia.
ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with potassium supplements increases the risk of hyperkalemia. However, concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels.

Likelihood Likely Evidence C
Potassium-Sparing Diuretics

Concomitant use increases the risk of hyperkalemia.

Potassium Citrate by SuperiorLabs: Common Questions

Does Potassium Citrate by SuperiorLabs interact with any medications?
Yes. Based on its ingredients, Potassium Citrate has a known interaction with 62 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Potassium Citrate contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I have kidney disease?
No — talk to your doctor first. Potassium supplements can build up to dangerous levels if your kidneys don't filter it well. This is a serious safety concern and requires medical guidance.
What are the side effects?
Common ones are digestive: stomach pain, belching, diarrhea, gas, nausea, or vomiting. Rare but serious effects — from dangerously high potassium levels — include heart rhythm problems, low blood pressure, and confusion.
Is potassium safe during pregnancy?
Dietary potassium is fine, but supplements are a different story. The data rates potassium as likely safe in pregnancy, but supplements need your doctor's approval because individual situations vary. Talk to your pharmacist or doctor before taking this.
What is potassium citrate used for?
The product facts don't specify a health purpose, so we can't tell you from our data what this supplement is intended to treat or support. Your pharmacist or the product label can clarify that for you.
Can I take this with my blood pressure medication?
It depends on which one. Some blood pressure drugs — especially diuretics, ACE inhibitors, and ARBs — don't mix safely with potassium supplements because they keep potassium in your body and raise the risk of dangerous high blood potassium levels. Run your exact medication through the checker on this page before you start.
