HelloPharmacist Scorecard of Potassium 85 mg by Dr. Clark Store

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.

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 at 85 mg per capsule. The capsule itself is gelatin.

Potassium is a mineral your body needs for nerve and muscle function, including heart rhythm. Your diet normally provides enough — fruits, vegetables, and dairy are loaded with it.

This supplement is meant for people whose doctors have determined they need extra, often because of certain medications or kidney issues.

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: Bone and muscle support.
  • We looked for evidence on: Muscle function, Electrolyte balance, Bone health.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't hold effectiveness ratings for potassium supplementation in our data. What the science shows about potassium's role in the body is well-established — it's essential for heart, nerve, and muscle function — but whether this particular dose works for any specific condition isn't rated in the facts we have.

Talk with your doctor about whether you actually need a supplement and what dose is right for you.

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 and normal. Supplements are a different story — they can raise your blood levels to dangerous highs, especially if you have kidney disease or take certain medications.

The most common side effects from oral potassium are stomach issues: abdominal pain, belching, diarrhea, nausea, and vomiting. Rarely, high potassium causes serious problems like irregular heartbeat, heart block, low blood pressure, and confusion.

In pregnancy, dietary potassium is fine, but supplements should only be used under medical guidance. The same goes for breastfeeding — check with your doctor first.

Because potassium supplements carry real risks, they're not something to take on your own — your doctor needs to monitor your blood levels.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
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.

Before taking this product, double-check with your pharmacist if you use potassium-sparing diuretics, ACE inhibitors, or angiotensin receptor blockers — all carry Moderate risk of dangerous potassium buildup. These drug types reduce how your kidneys clear potassium, so a supplement on top puts you at real risk of heart rhythm problems.

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.

This is a supplement that requires a conversation with your doctor or pharmacist, not a self-care item. If you've been told by your healthcare provider you need potassium supplementation and you don't take blood pressure medications, this might be for you — but your doctor will likely want to track your blood levels.

If you take any heart or blood pressure drug, especially for high blood pressure, check first.

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

Potassium 85 mg by Dr. Clark Store: Common Questions

Does Potassium 85 mg by Dr. Clark Store interact with any medications?
Yes. Based on its ingredients, Potassium 85 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 85 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.
Can I take this if I have kidney disease?
No — talk to your doctor first. Kidney disease makes it harder for your body to clear potassium, so supplements can build up to dangerous levels. This is a situation where medical guidance is essential before you start.
What are the common side effects?
Most people who take oral potassium experience stomach issues: abdominal pain, gas, belching, diarrhea, nausea, or vomiting. These are usually mild, but if they don't settle, let your pharmacist know.
Is potassium safe during pregnancy?
Potassium from food is fine during pregnancy. Supplements are rated likely safe, but the facts advise using them only under medical guidance. Talk with your doctor or midwife about whether you need supplemental potassium.
Why do I need to avoid this with blood pressure medications?
Blood pressure drugs like ACE inhibitors and ARBs work by changing how your kidneys handle potassium — they make your body hold onto more of it. Add a supplement and your blood potassium can climb too high, which causes heart rhythm problems and other serious effects.
Can I just take this without a doctor's say-so?
We wouldn't recommend it. Potassium supplements carry real risks if your levels go too high, and they interact with common medications. Your doctor needs to know you're taking it and ideally should check your blood potassium levels to make sure you're in a safe range.
