HelloPharmacist Scorecard of Potassium Citrate 99 mg by Solaray

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 supplement contains one active ingredient: potassium, supplied as potassium citrate at 99 mg per capsule. The capsule also holds several inactive ingredients — rice flour, cellulose, parsley, celery, dandelion, magnesium stearate, watercress, and oat straw — which are fillers and binders used to form and fill the capsule.

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: electrolyte balance.
  • We looked for evidence on: hypokalemia, potassium deficiency, muscle function.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The product facts we hold do not include effectiveness ratings for potassium citrate, so we can't tell you from our data whether it works for any particular purpose. If you're considering this for a specific reason — kidney stones, bone health, muscle function, or any other concern — ask your pharmacist or doctor what the evidence shows for your situation.

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 fine, but supplements can cause dangerously high blood levels in some people, particularly those with kidney disease. The most common side effects from oral potassium are digestive: abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting.

Rarely, very high potassium levels can cause serious heart problems — irregular heartbeat, heart block, low blood pressure, or mental confusion — and slow-release tablets have been linked to bleeding ulcers in the small intestine. During pregnancy, dietary potassium is appropriate, but supplements should only be used under medical guidance.

Breastfeeding presents the same caution: dietary sources are fine, but check with your doctor before taking this supplement.

Moderate identified

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.

Double-check any blood pressure or diuretic medication before taking this. Potassium-sparing diuretics, ACE inhibitors, and angiotensin receptor blockers (ARBs) all raise the risk of dangerously high potassium levels when combined with this supplement.

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.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.

Potassium Citrate 99 mg by Solaray: Common Questions

Does Potassium Citrate 99 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Potassium Citrate 99 mg 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 99 mg 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.
What's the difference between potassium from food and this supplement?
Food potassium is generally safe because your body naturally excretes what it doesn't need. Supplements are more concentrated and can push your levels dangerously high, especially if your kidneys don't work well or you take certain medications. That's why supplements need medical oversight but food doesn't.
Can I take this if I have high blood pressure?
It depends entirely on what medication you take for it. If you're on an ACE inhibitor, ARB, or potassium-sparing diuretic, this supplement could be risky. Talk with your doctor or pharmacist — they'll know your exact drug and whether potassium is okay for you.
What are the common side effects?
Most people who take potassium orally experience digestive upset: stomach pain, belching, diarrhea, gas, nausea, or vomiting. These are usually mild and go away, but if they're strong or you feel chest discomfort or unusual heart symptoms, stop and call your doctor right away.
Is it safe to take while breastfeeding?
Dietary potassium is fine while breastfeeding, but we don't have enough data on supplements. Check with your doctor or pharmacist before starting — they can advise you based on your individual situation.
Who should not take this?
Anyone with kidney disease should be especially careful — high potassium levels are a major risk. If you take a blood pressure, heart, or diuretic medication, talk to your pharmacist or doctor first. They'll tell you whether it's safe for you.
