HelloPharmacist Scorecard of Potassium Plus Iodine by Douglas Cooper Co.
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
Full disclosure
Potassium Plus Iodine contains 4 active ingredients. Sodium alginate and sodium provide supplemental sodium; potassium supplies supplemental potassium; and iodine rounds out the mineral profile.
The tablet also contains several inactive ingredients—cellulose, croscarmellose sodium, stearic acid, silica, and magnesium stearate—which are fillers and binders that give the pill its form and help it dissolve properly.
Does it work?
Strong evidence
The evidence on this product's active ingredients is mixed. Sodium is Likely Effective for cystic fibrosis and Possibly Effective for amphotericin B nephrotoxicity (kidney damage from a specific antifungal).
Claims about sodium for bipolar disorder and congestive heart failure lack sufficient reliable evidence to rate. Iodine is Likely Effective for preventing radiation exposure and treating iodine deficiency, and Possibly Effective for oral sores and gum disease.
We hold no effectiveness data for potassium alone in the facts we have on file.
How safe is it?
Well-documented data
Sodium is well tolerated at normal dietary amounts but carries real risks in excess—high intake is linked to high blood pressure, heart strain, and in rare cases, worsened cardiovascular or kidney disease. Iodine is well tolerated within normal intake limits but can cause thyroid problems, abdominal upset, diarrhea, headache, metallic taste, and in rare cases, serious allergic reactions.
Potassium from food is fine, but supplements can cause dangerously high blood levels, especially in people with kidney disease, leading to heart rhythm problems or even cardiac arrest in rare cases. The safety notes advise that while sodium and iodine are essential in small amounts, you should avoid high-dose supplementation without your doctor's guidance.
During pregnancy and lactation, sodium and iodine are rated Likely Safe, though iodine is also rated Possibly Unsafe—talk with your doctor about what's right for you and your baby. Potassium from diet is appropriate during pregnancy, but supplements require medical supervision.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you take any of these: potassium-sparing diuretics (water pills that save potassium), ACE inhibitors or ARBs (blood pressure medications), blood pressure drugs in general, corticosteroids (steroids), lithium (mood stabilizer), didanosine (HIV treatment), sodium phosphate (bowel cleansing agent), tolvaptan (for low sodium), antithyroid medications, or amiodarone (heart rhythm drug). All of these carry documented Moderate-severity interactions.
The bottom line
Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product is a mineral supplement combining sodium, potassium, and iodine. It may have a role if your doctor advises supplementation for a specific mineral deficiency, but the ingredient list carries multiple Moderate-severity interactions with common blood pressure, heart, and psychiatric medications.
Anyone taking diuretics, ACE inhibitors, ARBs, lithium, steroids, thyroid drugs, or amiodarone should not take this without clearing it first with their own doctor or pharmacist. Discuss your full medication list and whether supplementation makes sense for you.

For each ingredient in Potassium Plus Iodine with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Sodium Alginate
Antihypertensive Drugs
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
High intake of dietary sodium can increase systolic and diastolic blood pressure. Also, high intake of sodium may necessitate increased use of antihypertensive medications to achieve blood pressure control in some patients, such as those with chronic kidney disease.
Corticosteroids
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone.
Didanosine (Videx)
Concomitant use of didanosine with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia.
Didanosine formulations contain a significant amount of sodium.
Lithium
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion. Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate. Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L. Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
Sodium Phosphates
Theoretically, concomitant use of sodium phosphate with sodium supplements might increase the risk of hypernatremia.
Use of high doses (> 45 mL in 24 hours) of sodium phosphate, such as those used for bowel cleansing before surgery, can lead to serious electrolyte disturbances, including hypernatremia. The risk of hypernatremia is highest in the elderly and people with other risk factors for electrolyte disturbances.
Sodium-Containing Drugs
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population. Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
Tolvaptan (Samsca)
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia. Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.
Potassium
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.
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.
Potassium-Sparing Diuretics
Concomitant use increases the risk of hyperkalemia.
Using potassium-sparing diuretics with potassium supplements increases the risk of hyperkalemia.
Iodine
Amiodarone (Cordarone)
Combining iodine with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with iodine might increase the risk of having excessive iodine levels and adversely affecting thyroid function. Monitor thyroid function.
Antithyroid Drugs
Iodine might alter the effects of antithyroid drugs.
Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking iodine while using antithyroid drugs could alter the effects of the antithyroid drugs.
Lithium
Combining iodine with lithium might have additive hypothyroid effects.
Lithium can inhibit thyroid function. Several case reports suggest that concomitant use of lithium and potassium iodide can reduce thyroid function in otherwise healthy adults. Monitor thyroid function.
