HelloPharmacist Scorecard of Potassium Chelate 99 mg by Cooper Complete

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

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, delivered as a chelate form at 99 mg per capsule. Potassium is a mineral your body needs to keep your heart rhythm steady, support muscle function, and maintain proper fluid balance.

The capsule also holds inactive ingredients—microcrystalline cellulose, gelatin, silica, and vegetable stearate—which are fillers and binders that hold the capsule together.

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

This is a single-ingredient Potassium product and its label doesn't state a use — see Potassium's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The product facts we hold do not include effectiveness ratings for potassium supplementation. Whether a potassium supplement is right for your situation depends on your individual diet, kidney function, and medical history—something your doctor or pharmacist is best positioned to assess.

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 generally safe, but supplements can cause dangerously high blood levels in some people, especially those with kidney disease. Common side effects from oral potassium are usually mild—abdominal pain, belching, diarrhea, flatulence, nausea, or vomiting—but rare serious effects include irregular heartbeat, heart block, low blood pressure, and mental confusion.

During pregnancy, dietary potassium is appropriate, but use supplements only under medical guidance. The same caution applies while breastfeeding—check with your doctor before taking a potassium supplement.

The data we hold rates potassium as likely safe in pregnancy and lactation when used appropriately, but that's different from an open green light to self-supplement.

Side effects, ingredient by ingredient Potassium

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 you take this product, check with your pharmacist or doctor if you're on potassium-sparing diuretics (like spironolactone), ACE inhibitors (like lisinopril), or angiotensin receptor blockers (like losartan)—all Moderate-severity concerns. These medication types all raise potassium levels, and adding a supplement can push yours dangerously high.

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 are not a casual addition to your routine—they work against several major medication classes and can cause serious heart problems if your blood level gets too high. If you take a blood pressure or heart medication, have kidney disease, or aren't sure whether you actually need more potassium, talk it over with your doctor or pharmacist before starting.

This is one where personalized guidance matters more than the supplement itself.

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 Chelate 99 mg by Cooper Complete: Common Questions

Does Potassium Chelate 99 mg by Cooper Complete interact with any medications?
Yes. Based on its ingredients, Potassium Chelate 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 Chelate 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.
Is it safe to take potassium supplements if I have kidney disease?
No. The safety data specifically cautions that potassium supplements can cause dangerously high blood levels in people with kidney disease. Talk to your doctor before considering any potassium supplement.
What are the most common side effects?
The most common side effects are gastrointestinal: abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting. Most people tolerate potassium well when taken by mouth, but if you notice any of these, let your pharmacist know.
Can I take this while pregnant or breastfeeding?
Dietary potassium is fine, but supplements require medical guidance during both pregnancy and breastfeeding. The data rates potassium as likely safe when used appropriately, but that means you need your doctor's go-ahead first—not a self-directed choice.
What are the serious side effects I should watch for?
Rare but serious: irregular heartbeat, heart block, low blood pressure, and mental confusion. These are signs of dangerously high potassium in your blood. Stop and seek medical attention right away if you notice any of them.
Why is this supplement so restricted with blood pressure medications?
Many blood pressure and heart medications reduce how your kidneys excrete potassium. Adding a supplement on top raises your blood potassium to dangerous levels. Your medications are already managing your potassium balance—this supplement can disrupt that.
