HelloPharmacist Scorecard of Potassium 99 mg by Nature's Life

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 at 99 mg per capsule. Potassium is an electrolyte your body needs for muscle and nerve function, heart rhythm, and fluid balance.

The capsule also holds inactive ingredients—gelatin, cellulose, magnesium stearate, and silica—which are standard binders and fillers.

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 this product in our database. Potassium supplements are used to prevent or correct low potassium levels, but any claims about how well this formulation works at that dose would need to come from your doctor or the product's own clinical evidence.

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. Supplements, however, can raise blood levels dangerously in people with kidney disease or other conditions that limit potassium clearance.

Common mild side effects taken by mouth include stomach pain, belching, diarrhea, gas, nausea, and vomiting. Rare but serious effects of high potassium are irregular heartbeat, heart block, low blood pressure, and confusion.

The product notes say dietary potassium is appropriate during pregnancy and breastfeeding, but supplements should only be used under medical guidance in both cases. Talk with your doctor or pharmacist before taking this if you're pregnant, nursing, or have kidney problems.

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 taking this, check with your doctor or pharmacist if you're on potassium-sparing diuretics (water pills that keep potassium), ACE inhibitors, or angiotensin receptor blockers (ARBs)—all carry a Moderate risk of high potassium levels. The same goes for any other medication that might affect your potassium balance or 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 useful only if your doctor has found you're low in potassium and recommends supplementing. If you take blood pressure medication, a diuretic, or have kidney issues, you need your healthcare provider's input before starting—don't add this on your own.

Potassium imbalance is a real safety risk. Check with your doctor or pharmacist to see if this product is right for you.

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

Potassium 99 mg by Nature's Life: Common Questions

Does Potassium 99 mg by Nature's Life 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.
Can I take this while pregnant or breastfeeding?
Potassium from food is fine during pregnancy and breastfeeding. However, supplements should only be used under medical guidance—there isn't enough data to know either way on your own. Talk with your doctor or pharmacist for personalized advice.
What side effects might I notice?
Common ones taken by mouth are stomach pain, belching, diarrhea, gas, nausea, and vomiting. Serious effects are rare but can include irregular heartbeat, low blood pressure, and confusion—usually from high potassium levels.
Is this safe if I have kidney disease?
No, not without close medical oversight. Kidney disease limits how much potassium your body can clear, so supplements can push levels dangerously high. Check with your doctor before taking this.
Why can't I just take this with my blood pressure medication?
Many blood pressure drugs (ACE inhibitors and ARBs) slow how your body removes potassium. Adding a supplement stacks that effect and raises the risk of dangerously high potassium, which can cause heart problems. Your doctor needs to know if you're supplementing.
What exactly does potassium do?
It's an electrolyte your body needs for muscle and nerve signals, heart rhythm, and keeping fluids balanced. You usually get enough from food, so supplements are only for people with confirmed low levels.
