HelloPharmacist Scorecard of Chelated Potassium Gluconate by Foster Regal

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 supplement contains one active ingredient: potassium, a mineral your body needs for nerve and muscle function, including your heartbeat. It's delivered here as potassium gluconate in chelated form, which is a binding method meant to aid absorption.

The tablet also contains inactive ingredients — calcium carbonate, cellulose, stearic acid, magnesium silicate, and silica — which are fillers and binders that hold the tablet 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.

We hold no effectiveness data for potassium supplements in our records, so we can't tell you whether this product is proven to work for any particular purpose. If you're considering it to correct a potassium deficiency, that's a medical decision — your doctor can check your blood levels and recommend whether you need supplementation.

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 necessary. Supplements are a different story: they can raise your blood levels dangerously, especially if you have kidney disease.

The facts advise caution because supplements pose risks that food does not. Common side effects when taken by mouth include abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting.

Rare but serious effects from very high potassium levels include irregular heartbeat, heart block, low blood pressure, and confusion. Slow-release potassium tablets have also been linked to bleeding ulcers in the small intestine.

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

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.

If you take potassium-sparing diuretics, ACE inhibitors (like lisinopril or enalapril), or ARBs (like losartan or valsartan), double-check with your pharmacist or doctor before adding this supplement — all three drug classes raise your risk of dangerously high blood potassium when combined with potassium supplements.

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 potassium supplement, not a multivitamin or general wellness product — it's meant for people with confirmed potassium deficiency, usually prescribed by a doctor. If you take a blood pressure medication (especially ACE inhibitors, ARBs, or potassium-sparing diuretics), or if you have kidney disease, you need to talk with your doctor or pharmacist before starting it.

Even if you don't take those drugs, your own healthcare provider should be in the loop, since potassium imbalance can affect your heart.

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.

Chelated Potassium Gluconate by Foster Regal: Common Questions

Does Chelated Potassium Gluconate by Foster Regal interact with any medications?
Yes. Based on its ingredients, Chelated Potassium Gluconate 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?
Chelated Potassium Gluconate 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'm pregnant or breastfeeding?
Potassium from your regular diet is fine during pregnancy and breastfeeding, but supplements should only be used under medical guidance in both cases. Talk with your doctor or pharmacist before starting this product if you're pregnant, trying to become pregnant, or breastfeeding.
What are the most common side effects?
The most common ones are stomach and digestive — abdominal pain, belching, diarrhea, gas, nausea, and vomiting. These happen because potassium tablets can irritate your digestive tract.
Who shouldn't take this?
Anyone with kidney disease needs to be especially careful, since damaged kidneys can't regulate potassium levels well and supplements can build up to dangerous amounts. If you take a blood pressure medication, particularly ACE inhibitors, ARBs, or potassium-sparing diuretics, you should check with your doctor before starting — these combinations risk high blood potassium that can affect your heart.
What's the difference between potassium from food and a potassium supplement?
Food potassium is fine for everyone because your body regulates it naturally — you only absorb what you need and excrete the rest. Supplements deliver a concentrated dose that your kidneys have to handle all at once, so they carry real risk of buildup, especially if your kidney function is compromised or you're on certain medications.
Can this cause serious problems?
Yes, though they're rare. Very high potassium levels can trigger irregular heartbeat, heart block, low blood pressure, or confusion. Slow-release potassium tablets have also been linked to bleeding ulcers in the small intestine, so talk with your doctor about the safest form for you.
