HelloPharmacist Scorecard of Liqui-Dulse Iodine by Bernard Jensen's
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
This product contains 2 active ingredients: iodine and dulse whole extract. Iodine is the essential mineral your thyroid needs to make hormones that control your metabolism and energy.
Dulse is a seaweed that naturally contains both iodine and potassium. The product also has glycerin and deionized water as inactive ingredients to keep it in liquid form.
Does it work?
Strong evidence
Iodine in this product is likely effective for protecting your thyroid if you're exposed to radiation and for treating iodine deficiency—a real concern in parts of the world where iodine is scarce. It's possibly effective for mouth sores (oral mucositis) and gum disease (periodontitis).
Dulse as a supplement, though, has insufficient evidence to rate whether it helps with cholesterol or iodine deficiency on its own; the research isn't clear enough yet.
How safe is it?
Well-documented data
Iodine is well tolerated in normal dietary amounts, but high doses can mess with your thyroid—causing either too much or too little thyroid hormone. The most common side effects at higher intakes are nausea, stomach upset, diarrhea, metallic taste, headache, and a runny nose.
In rare cases, iodine can trigger a serious allergic reaction. Chronic use of very large amounts has been reported to cause acneform skin lesions (a rash that looks like acne).
Pregnancy and early lactation call for caution: adequate iodine matters for your baby's brain development, but excess iodine passes into breast milk, so stick to the dose your doctor recommends and avoid high-dose products. Dulse as a food is generally safe, but concentrated supplements can contain unpredictable iodine and potassium levels with limited safety data, so they're best avoided in pregnancy and while breastfeeding unless your doctor approves.
Meds to double-check
Moderate interaction found
Before you take this product, check with your pharmacist if you're on lithium (a mood stabilizer), antithyroid drugs, amiodarone (a heart rhythm medicine), thyroid hormone replacement, digoxin (a heart medication), ACE inhibitors or ARBs (blood pressure drugs), or potassium-sparing diuretics. These are the main medication types that interact with the iodine and potassium in this product.
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 makes sense if you're iodine-deficient or your doctor recommends it for thyroid protection. Be very careful if you take lithium, heart medications, blood pressure drugs, thyroid medication, or antithyroid drugs—talk to your pharmacist or doctor before starting.
Avoid high doses on your own, especially in pregnancy and while breastfeeding.

Liqui-Dulse Iodine by Bernard Jensen's Drug Interactions
HelloPharmacist Interaction Report
Bernard Jensen's Liqui-Dulse Iodine contains two active ingredients—iodine and dulse whole extract—and together they interact with a number of medications, most notably those that affect thyroid function and potassium balance.
The most serious concern is with lithium, a mood stabilizer: iodine can add to lithium's effect of lowering thyroid function, and your doctor will want to monitor your thyroid blood work if you're on both.
Read the full breakdown — every affected drug type, severity by severity
Iodine also interacts moderately with antithyroid drugs (used to treat overactive thyroid) and with amiodarone, a heart rhythm medication that's itself very high in iodine—combining them risks pushing your iodine levels too high and damaging your thyroid. Dulse brings its own iodine content into the mix, so these same risks apply through the dulse ingredient as well.
Additionally, dulse is rich in potassium, which can interact with heart medications like digoxin and with blood pressure drugs including ACE inhibitors, ARBs, and potassium-sparing diuretics—the concern is high potassium levels in your blood, though these interactions haven't been proven in people yet.
Thyroid hormone replacement medication and antithyroid drugs may also have their effects altered by the iodine and dulse in this product. Altogether, these interactions span 86 individual medications.

For each ingredient in Liqui-Dulse 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.
Dulse Whole Extract
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.
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.
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.
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.
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.
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.
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.
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.
