HelloPharmacist Scorecard of Combination Potassium by Nature's Sunshine

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.

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 1 of its 8 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (2,080 mg) without saying how much of each component you get.

This capsule contains eight active ingredients. Potassium appears twice — once as potassium itself and again as dipotassium phosphate — and both forms carry the same interaction risks.

The other six active ingredients are alfalfa (a legume), horseradish (a pungent root), horsetail (a plant), white cabbage, kelp, and dulse (a seaweed). The product also contains inactive ingredients: the capsule itself, magnesium stearate, and silicon dioxide.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: maintain fluid and electrolyte balance.
  • We looked for evidence on: Hypertension, Cardiovascular disease (CVD), Metabolic syndrome, Diabetes, Impaired glucose tolerance (prediabetes), Electrolyte balance — and 2 related terms.
  • The closest evidence on file: Alfalfa is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Fucus Vesiculosus is rated "Insufficient Reliable Evidence To Rate" for Cardiovascular disease (CVD), Impaired glucose tolerance (prediabetes), Metabolic syndrome.
  • Also on file: Horsetail is rated "Insufficient Reliable Evidence To Rate" for Hypertension.

The evidence we hold doesn't establish that any of the ingredients in this product work for a specific health purpose. Alfalfa, horseradish, horsetail, white cabbage, kelp, and dulse all carry ratings of insufficient reliable evidence for the conditions they're traditionally used for—conditions range from diabetes to respiratory infections to heart health.

Potassium itself isn't rated for effectiveness here because it's an essential mineral your body needs for basic function, not a remedy for disease. If you're considering this product for a particular reason, chat with your pharmacist about what the evidence actually shows.

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 6 of the 7 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 7 of 7.
  • General safety write-ups exist for 7 of 7.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Potassium supplements can cause dangerously high blood levels in some people, especially those with kidney disease, even though dietary potassium is fine. Common side effects from potassium are abdominal pain, belching, diarrhea, nausea, and vomiting.

In rare cases, very high potassium can trigger heart rhythm problems, heart block, or even cardiac arrest. Alfalfa is generally well tolerated orally but can cause abdominal discomfort, diarrhea, and flatulence; a rare serious effect is a lupus-like syndrome after long-term use.

Horseradish in large amounts may cause bloody vomiting, diarrhea, and in rare cases fainting. Horsetail has limited safety research and may cause abdominal bloating, more bowel movements, and nausea; crude horsetail contains thiaminase, which can cause thiamine deficiency with prolonged use.

White cabbage is safe as a food but hasn't been well studied in concentrated supplement form. Kelp's high iodine can disrupt thyroid function and may concentrate heavy metals.

Dulse is rich in both potassium and iodine, both of which carry risks at high doses. For pregnancy, alfalfa and horsetail should be avoided; horseradish safety hasn't been established; white cabbage safety data is insufficient; and kelp and dulse are possibly unsafe.

For breastfeeding, the product facts note limited data for most ingredients—talk with your doctor before using.

Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 7 of the 7 matched ingredients can interact with medications — Alfalfa, Cabbage, Horseradish, Fucus Vesiculosus, Horsetail, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,331 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 Combination Potassium, double-check these medication types with your pharmacist: blood thinners like warfarin (Major severity from alfalfa); potassium-sparing diuretics, ACE inhibitors, and ARBs (Moderate from potassium); blood pressure and heart drugs including lithium, digoxin, and amiodarone (Moderate); thyroid and antithyroid drugs (Moderate from kelp and dulse); antidiabetes drugs (Moderate from alfalfa, horsetail, and white cabbage); contraceptive pills and estrogen therapy (Moderate from alfalfa); immunosuppressants (Moderate from alfalfa); photosensitizing drugs (Moderate from alfalfa); other diuretics (Moderate from horsetail); HIV antiretrovirals including nucleoside reverse transcriptase inhibitors and efavirenz (Moderate from horsetail); and liver-metabolized drugs including acetaminophen and oxazepam (Moderate from white cabbage and kelp).

Kelp9 drug types · 891 drugs

Amiodarone (Cordarone)

Theoretically, combining Fucus vesiculosus with amiodarone might cause excessively high iodine levels.
Fucus vesiculosus contains high concentrations of iodine. Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.

Likelihood Probable Evidence D
Antithyroid Drugs

Due to its iodine content, Fucus vesiculosus might alter the effects of antithyroid drugs.
Fucus vesiculosus contains high concentrations of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Fucus vesiculosus while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Lithium

Concomitant use of Fucus vesiculosus and lithium has resulted in hyperthyroidism.
There is a case of hyperthyroidism occurring in a patient taking Fucus vesiculosus and lithium. Monitor thyroid hormones closely in patients taking lithium and Fucus vesiculosus concomitantly.

Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant in humans.

Likelihood Possible Evidence D
Alfalfa full monograph & interactions

White Cabbage6 drug types · 325 drugs

Acetaminophen (Tylenol, Others)

Cabbage might increase clearance and reduce the effects of acetaminophen.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases acetaminophen levels by as much as 16%, with some evidence suggesting that this effect is due to increased elimination through glucuronide conjugation.

Likelihood Probable Evidence B
Antidiabetes Drugs

Theoretically, cabbage might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal and in vivo research suggests that cabbage might have hypoglycemic effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, cabbage might decrease levels of drugs metabolized by CYP1A2.
Some animal research suggests that cabbage or its constituent indole-3-carbinol might increase drug metabolism and elimination by stimulating CYP1A2 activity.

Likelihood Possible Evidence D
Glucuronidated Drugs

White Cabbage full monograph & interactions

Horsetail5 drug types · 188 drugs

Antidiabetes Drugs

Theoretically, taking horsetail with antidiabetes drugs might increase the risk of hypoglycemia.
Equisetum myriochaetum has demonstrated hypoglycemic activity in clinical research. In an animal diabetic model, Equisetum giganteum had hypoglycemic effects. It is unclear whether other horsetail species have hypoglycemic effects.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, taking horsetail with diuretic drugs might increase potassium loss and the risk of hypokalemia.
Laboratory research shows that various species of horsetail have diuretic properties. Due to its diuretic effects, there has been concern that taking horsetail along with potassium-depleting diuretics might increase the risk for hypokalemia. However, pharmacokinetic research in humans shows that taking horsetail 900 mg daily for 4 days does not affect urinary excretion of electrolytes, including potassium and sodium, despite having a diuretic effect similar to taking hydrochlorothiazide 25 mg daily. It is unclear if taking horsetail for a longer duration would affect electrolyte levels. Until more is known, use with caution.

Likelihood Possible Evidence D
Efavirenz (Sustiva)

Theoretically, horsetail might decrease the levels and clinical effects of efavirenz.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral regimen that included efavirenz. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing horsetail, the viral loads became undetectable in both cases. The exact mechanism of this interaction is unknown. It is also unclear if this interaction is specific to efavirenz or if it is related to various components of antiretroviral therapy.

Likelihood Possible Evidence D
Lithium

Theoretically, horsetail might increase the levels and adverse effects of lithium.
Animal research suggests that horsetail has diuretic properties. Theoretically, due to these potential diuretic effects, horsetail might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Nucleoside Reverse Transcriptase Inhibitors (Nrtis)

Theoretically, horsetail might decrease the levels and clinical effects of NRTIs.
In two case reports, patients were found to have detectable viral loads when taking horsetail-containing supplements along with an antiretroviral therapy. In one case, the antiretroviral regimen included zidovudine, lamivudine, and efavirenz; in the other case, the regimen consisted of emtricitabine, tenofovir disoproxil fumarate, and efavirenz. One month after discontinuing the supplement, the viral loads became undetectable in both cases. The exact mechanism of these interactions is unknown. It is also unclear if these interactions are specific to NRTIs or if they are related to various components of antiretroviral therapy.

Likelihood Possible Evidence D
Horsetail full monograph & interactions

Dulse7 drug types · 85 drugs

Amiodarine (Cordarone)

Theoretically, combining dulse with amiodarone might cause excessively high iodine levels.
Dulse is rich in iodine, and amiodarone contains 37.3% iodine and can increase iodine levels.

Likelihood Possible Evidence D
Antithyroid Drugs

Theoretically, due to its iodine content, dulse might alter the effects of antithyroid drugs.
Dulse is rich in iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, dulse might increase the risk of hyperkalemia when taken with digoxin.
Dulse is rich in potassium, and digoxin can increase potassium levels in the blood. This interaction has not been demonstrated in humans.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, due to its iodine content, dulse might alter the effects of thyroid hormone.
Dulse is rich in iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Although dulse has been associated with a statistically significant increase in thyroid stimulating hormone (TSH) levels in clinical research, clinically significant increases have not been documented.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, dulse might increase the risk of hyperkalemia when taken with ACEIs.
Dulse is rich in potassium. ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels. However, using these drugs while consuming dulse in quantities that provide larger amounts of potassium daily might increase the risk of hyperkalemia. Additionally, in vitro research suggests that dulse protein hydrolysates inhibit the activity of ACE. However, these effects have not been demonstrated in humans.

Likelihood Possible Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, dulse might increase the risk of hyperkalemia when taken with ARBs.
Dulse is rich in potassium. ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels. However, using these drugs while consuming dulse in quantities that provide higher amounts of potassium daily might increase the risk of hyperkalemia. Additionally, in vitro research suggests that dulse protein hydrolysates inhibit the activity of angiotensin converting enzyme (ACE). However, these effects have not been demonstrated in humans.

Likelihood Possible Evidence D
Potassium-Sparing Diuretics

Theoretically, dulse might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dulse is rich in potassium, and potassium-sparing diuretics can increase potassium levels in the blood. This interaction has not been shown in humans.

Combination Potassium by Nature's Sunshine: Common Questions

Does Combination Potassium by Nature's Sunshine interact with any medications?
Yes. Based on its ingredients, Combination Potassium has a known interaction with 1,330 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Combination Potassium contains 8 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 a blood pressure medication?
It depends which one. If you take an ACE inhibitor, ARB, or potassium-sparing diuretic, this product raises your risk of dangerously high blood potassium. If you take digoxin or amiodarone for your heart, there are concerns too. Don't start without checking with your pharmacist first—this is one to verify against your exact medications.
Can I take this if I'm on warfarin?
The alfalfa in this product contains a lot of vitamin K, which can interfere with how warfarin works. This is a Major-level interaction. You should not take this without your doctor's permission, and if you do, your anticoagulation (blood-thinning effect) will need to be monitored closely.
Is it safe to take while I'm pregnant or breastfeeding?
The product facts advise caution or avoidance for most ingredients during pregnancy and breastfeeding. Potassium from your normal diet is fine, but supplements should only be used under medical guidance during pregnancy. For breastfeeding, there isn't enough data on most of these ingredients. Talk with your doctor or pharmacist for personalized advice before using this product.
What are the most common side effects?
From the potassium itself, you might experience abdominal pain, belching, diarrhea, flatulence, nausea, or vomiting. Alfalfa and horsetail can cause similar digestive upset. In rare cases, very high potassium levels can cause serious heart rhythm problems or confusion.
Will this help my blood sugar or thyroid?
We don't have evidence that shows these ingredients work for blood sugar or thyroid conditions. What we do have is evidence that some of them—like alfalfa and horsetail—may affect blood sugar drugs you're taking, and kelp and dulse may interfere with thyroid medications. They're not established treatments for these conditions.
Is it safe for people with kidney disease?
No. Potassium supplements can cause dangerously high blood levels in people with kidney disease. If you have kidney problems, avoid this product and talk to your doctor or pharmacist before taking any potassium supplement.
