HelloPharmacist Scorecard of Potassium 99 mg by Meijer

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, the mineral your body needs for heart rhythm, nerve signals, and muscle function. The dose is 99 mg per serving — a modest amount intended to top up your dietary intake.

The other ingredients listed are inactive: potassium gluconate (a form of the mineral itself within the tablet structure), stearic acid (a binder), and minor additives.

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

The product facts we hold do not include effectiveness ratings for potassium supplementation. We cannot tell you from this data alone whether 99 mg per serving is enough to address a deficiency or support your health goals — that depends on your individual needs and current intake.

Talk with your doctor or pharmacist about whether supplementing makes sense 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 for everyone. Supplements are a different story: they're generally well-tolerated by mouth, but they can cause dangerously high blood potassium levels in certain people — especially those with kidney disease.

Common side effects include stomach pain, belching, diarrhea, gas, nausea, and vomiting. In rare cases, very high potassium can trigger irregular heartbeat, low blood pressure, heart block, or confusion.

During pregnancy, dietary potassium is appropriate; supplements should only be used under medical guidance. While breastfeeding, dietary potassium is fine, but check with your doctor before taking a supplement.

If you have kidney problems, heart disease, or take any blood pressure medication, talk with your doctor or pharmacist before starting this product.

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, check with your doctor or pharmacist if you take a potassium-sparing diuretic (a water pill that keeps potassium), an ACE inhibitor, or an angiotensin receptor blocker (ARB) — all three carry a Moderate risk of high blood potassium levels when combined with potassium supplements. Altogether, these interactions span 62 individual medications.

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 99 mg potassium supplement is a modest dose that works well for some people to fill a dietary gap — but only if your kidneys are healthy and you're not on certain blood pressure or heart medications. If you take an ACE inhibitor, an ARB, or a potassium-sparing diuretic, this supplement poses a real risk.

Talk with your own doctor or pharmacist before you start it.

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

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

Potassium 99 mg by Meijer: Common Questions

Does Potassium 99 mg by Meijer interact with any medications?
Yes. Based on its ingredients, Potassium 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 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 this safe during pregnancy?
Potassium from food is fine during pregnancy. Supplements are rated likely safe, but use them only under your doctor's guidance — don't start one on your own during pregnancy.
Can I take this while breastfeeding?
Dietary potassium is appropriate while breastfeeding. If you're thinking about a supplement, check with your doctor or pharmacist first to make sure it's right for you and your baby.
What are the most common side effects?
Taken by mouth, potassium is generally well-tolerated. The most common side effects are stomach upset — belching, gas, diarrhea, nausea, vomiting, and abdominal pain. Rare serious effects include irregular heartbeat and low blood pressure from very high potassium levels.
Does this really work to fix low potassium?
The product facts we have don't include effectiveness ratings for potassium supplementation. Whether 99 mg per serving will help depends on your actual potassium level and how much you get from food. Your doctor can check your blood potassium and advise whether you need a supplement and how much.
Why is this dose only 99 mg?
That's just under 100 mg — a modest amount. Many potassium supplements are dosed this way to stay under certain regulatory limits. Your body also gets potassium from bananas, spinach, beans, and other foods; this supplement tops up your dietary intake but isn't meant to be your only source.
Is this safe if I have kidney disease?
No — potassium can build to dangerous levels in your blood if your kidneys don't work well. If you have kidney disease or any kidney problems, do not take this supplement without your doctor's approval. This is one of the most important safety concerns with potassium supplements.
