HelloPharmacist Scorecard of Potassium 99 mg by Country Life Target-Mins

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 99 mg per tablet. Potassium is a mineral your body needs for muscle function, heart rhythm, and nerve signaling.

The tablet also contains inactive ingredients — cellulose, stearic acid, glycerin, silica, magnesium stearate, and vegetable glaze — which are standard binders and coatings.

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: neuromuscular function and nerve signal regulation.
  • We looked for evidence on: Muscle function, Nerve conduction, 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, so I can't tell you from our monograph whether this dose is proven to correct a deficiency or support any particular health outcome. What the science shows about potassium's role in the body is established — but whether a 99 mg supplement dose is right for you depends on your individual needs and blood levels, which your doctor can 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 safe for almost everyone. Supplements are different — they can raise your blood potassium to dangerously high levels, especially if you have kidney disease.

High blood potassium can cause irregular heartbeat, low blood pressure, and heart block. Common mild side effects from oral potassium include stomach pain, belching, diarrhea, gas, nausea, and vomiting.

The facts note that slow-release potassium tablets have rarely been linked to bleeding ulcers in the duodenum (part of the small intestine). For pregnancy and breastfeeding, dietary potassium is fine, but use supplements only under your doctor's guidance — the data rates it likely safe in pregnancy and lactation, yet medical supervision is still advised.

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, double-check with your pharmacist if you're on potassium-sparing diuretics, ACE inhibitors, or ARBs (all Moderate risk for high blood potassium). Also mention any kidney disease or medications that affect kidney function.

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 supplement is for people whose doctor has identified a potassium shortfall and approved supplementation. If you take a blood pressure or heart medication, especially ACE inhibitors, ARBs, or potassium-sparing diuretics, talk to your pharmacist or doctor before starting — your kidney function and current potassium level are critical to safety.

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.
