HelloPharmacist Scorecard of Potassium by Solgar

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 is a single-ingredient supplement: potassium. The tablet contains one active ingredient — potassium — along with inactive ingredients (dicalcium phosphate, microcrystalline cellulose, vegetable stearic acid, silica, vegetable cellulose, and vegetable magnesium stearate) that give the tablet its form and stability.

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, electrolyte balance.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

We don't hold effectiveness ratings for potassium in our data. What we do know is that potassium is an essential mineral your body needs for heart rhythm, muscle function, and blood pressure regulation.

Most people get enough from food — fruits, vegetables, beans, and dairy are all rich sources. Whether a supplement is right for you depends on your individual needs and kidney function, so that's a conversation to have with your doctor or pharmacist.

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, though, are a different story.

High blood potassium levels can cause serious heart problems — irregular heartbeat, low blood pressure, heart block, and even cardiac arrest — especially in people with kidney disease or those taking certain medications. On the milder side, some people experience belly pain, gas, diarrhea, nausea, and vomiting.

Slow-release tablets have rarely been linked to bleeding ulcers. For pregnancy and breastfeeding, dietary potassium is fine, but supplements need medical guidance.

There isn't enough data on file about supplement safety in lactation — talk it through with your doctor or pharmacist before starting one while breastfeeding.

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 Solgar Potassium, double-check with your doctor or pharmacist if you take any potassium-sparing diuretics, ACE inhibitors, or angiotensin receptor blockers (ARBs) — all carry a Moderate risk of raising blood potassium to unsafe levels. These are common medications for blood pressure and heart conditions, so this is an important conversation to have before you start.

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 only for people whose doctor or pharmacist says they need one — they're not for general wellness. If you take a blood pressure or heart medication, especially ACE inhibitors, ARBs, or potassium-sparing diuretics, check with your doctor or pharmacist before taking this product; the risk of dangerously high blood potassium is real.

Even without medications, if you have kidney disease or heart disease, you need clearance before starting. Have this conversation with your healthcare provider.

Formula

Potassium is an essential mineral needed by the body. It is vital for muscle activity. As an important electrolyte, it regulates nerve signals from the brain and spinal column to muscles, thus promoting healthy neuromuscular function. It also promotes proper fluid balance in the body and helps to attract nutrients into cells.

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 by Solgar: Common Questions

Does Potassium by Solgar interact with any medications?
Yes. Based on its ingredients, Potassium 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 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 on blood pressure medication?
It depends on which one. If you take an ACE inhibitor (like lisinopril), an ARB (like losartan), or a potassium-sparing diuretic, this supplement can raise your blood potassium to dangerous levels. Talk to your doctor or pharmacist first — don't start it on your own.
Is potassium supplement safe for everyone?
No. It's risky if you have kidney disease, heart disease, or take certain medications. Even in healthy people, high doses can cause serious heart rhythm problems. This isn't a supplement for general wellness — only take it if your doctor says you need it and gives you the dose.
What side effects might I get?
Most common are belly pain, gas, diarrhea, nausea, and vomiting. Serious ones are rare but real — high potassium can cause irregular heartbeat, low blood pressure, heart block, or even cardiac arrest. Slow-release tablets have occasionally caused bleeding ulcers.
Is it safe to take while pregnant or breastfeeding?
Potassium from food is fine during pregnancy and breastfeeding. Supplements are different — they should only be used under medical guidance in pregnancy. For breastfeeding, there's not enough safety data on file, so ask your doctor or pharmacist before starting one.
Why would someone need a potassium supplement?
Most people get plenty of potassium from food — fruits, vegetables, beans, and dairy are all good sources. Supplements are for people whose doctor has found they genuinely need one, usually because of certain medications or health conditions that lower blood potassium.
