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.

Somaplex 11 Potassium contains one active ingredient: potassium gluconate, a form of potassium in liquid form. The product also contains water and ethyl alcohol as inactive ingredients.

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.

The product facts we hold do not include effectiveness data for potassium gluconate as a supplement ingredient.

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 a normal diet is fine, but this supplement can cause dangerously high blood levels in some people — especially those with kidney disease — so it should only be used under medical guidance. Most people tolerate potassium supplements well when taken by mouth.

The most common side effects are gastrointestinal: abdominal pain, belching, diarrhea, flatulence, nausea, and vomiting. In rare cases, very high potassium levels can trigger heart rhythm problems (arrhythmias), low blood pressure (hypotension), heart block, or even cardiac arrest — symptoms include mental confusion and severe chest discomfort.

For pregnancy and breastfeeding, dietary potassium is appropriate, but do not use supplements without checking with your doctor or pharmacist first. The safety data indicate likely safety, but that guidance applies only when use is medically appropriate for you.

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 Somaplex 11 Potassium, double-check if you're on any potassium-sparing diuretics, ACE inhibitors, or ARBs. All three drug types carry Moderate interaction risk and can raise your potassium to unsafe levels when combined with this supplement.

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 potassium supplement is for people whose doctor has determined they need extra potassium and confirmed their kidneys can handle it safely. Do not start it if you take blood pressure drugs — especially potassium-sparing diuretics, ACE inhibitors, or ARBs — without checking with your pharmacist first.

Talk to your doctor or pharmacist before using it during pregnancy or while breastfeeding.

Potassium Gluconate3 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.

11 Potassium by Somaplex: Common Questions

Does 11 Potassium by Somaplex interact with any medications?
Yes. Based on its ingredients, 11 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?
11 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.
What are the most common side effects?
Stomach and digestive upset — abdominal pain, belching, diarrhea, gas, nausea, and vomiting. These happen because potassium irritates the digestive tract.
Can I take this if I have kidney disease?
No — the facts specifically caution against it. Potassium supplements can cause dangerously high blood levels in people with kidney disease. Talk to your nephrologist or pharmacist before considering it.
Is it safe to take during pregnancy?
Dietary potassium is fine, but supplements need medical approval. The data show likely safety, but that applies only when your doctor says it's right for you. Check with your doctor or pharmacist before using it.
Can I take this while breastfeeding?
Potassium from food is appropriate, but check with your doctor before using supplements while breastfeeding. They can advise whether it's safe for both you and your baby in your situation.
What happens if potassium gets too high?
Very high potassium levels can cause irregular heartbeat, heart block, dangerously low blood pressure, and confusion. These are serious — call 911 or seek emergency care if you experience chest pain, severe shortness of breath, or fainting.
