Below is general information about the safety of the known ingredients contained in the product Dulse Liquid. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in food amounts. Dulse has a long history of use as a food ingredient in various parts of the world (103315,103317,103321).
POSSIBLY SAFE ...when used topically and appropriately (103322). There is insufficient reliable information available about the safety of dulse when used in amounts greater than those found in foods.
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of dulse when used in medicinal amounts during pregnancy or lactation; avoid amounts greater than those found in foods.
LIKELY SAFE ...when used orally and appropriately. Iodine is safe in amounts that do not exceed the tolerable upper intake level (UL) of 1100 mcg daily (7135,103070). Higher doses can be safely used with appropriate medical monitoring (2197,7080). In some regions of the world, such as Japan, daily dietary intake is estimated to be as high as 5,280-13,800 mcg without adverse outcomes (16747). ...when used topically and appropriately, as a 2% solution. A 2% iodine solution is an FDA-approved prescription product (15).
POSSIBLY UNSAFE ...when used orally in high doses. Tell patients to avoid prolonged use of doses exceeding the UL of 1100 mcg daily without proper medical supervision. There is concern that higher intake can increase the risk of side effects such as thyroid dysfunction, as well as thyroiditis, thyroid papillary cancer, thyrotoxicosis, and atrial fibrillation (7135,55962,56013). However, in some regions of the world such as Japan, daily dietary intake is estimated to be as high as 5,280-13,800 mcg without adverse outcomes (16747).
CHILDREN: LIKELY SAFE
when used orally and appropriately (7135).
Iodine is safe in amounts that do not exceed the tolerable upper intake level (UL) of 200 mcg daily for children 1-3 years, 300 mcg daily for children 4-8 years, 600 mcg daily for children 9-13 years, and 900 mcg daily for adolescents (7135). ...when used topically as a 2% solution (15). Iodine is an FDA-approved prescription product.
CHILDREN: POSSIBLY UNSAFE
when used orally in doses exceeding the UL (7135,108709).
Higher intake can cause thyroid dysfunction (7135) and may be associated with a modest reduction in intelligence (108709).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Iodine is safe in amounts that do not exceed the tolerable upper intake level (UL) of 1100 mcg daily in those 18 years and older or 900 mcg daily in those 14-18 years of age (7135,103070). Iodine needs increase during pregnancy and lactation and adequate intakes should begin as soon as a patient is aware of the pregnancy, or earlier in areas of potential deficiency (17920). ...when used topically as a 2% solution (15). Iodine is an FDA-approved prescription product.
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in doses exceeding the UL.
Higher intake can cause thyroid dysfunction (7135). Also, higher intakes during pregnancy cause increased iodine levels in breast milk and infant blood samples. Higher iodine intake during pregnancy has also been associated with an increased risk of congenital hypothyroidism and reduced mental and physical development in the offspring (56089,91390,91394,91395).
Below is general information about the interactions of the known ingredients contained in the product Dulse Liquid. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Dulse is rich in potassium (103317). ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion (95628). Concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels (95628). 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 (103319). Theoretically, concomitant use of these drugs with dulse might increase their effects and side effects. However, these effects have not been demonstrated in humans.
Details
The ACE inhibitors include benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), moexipril (Univasc), perindopril (Aceon), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).

Dulse is rich in potassium (103317). ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion (95628). Concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels (95628). 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) (103319). Theoretically, concomitant use of ARBs with dulse might increase their effects and side effects. However, these effects have not been demonstrated in humans.
Details
Some ARBs include losartan (Cozaar), valsartan (Diovan), irbesartan (Avapro), candesartan (Atacand), telmisartan (Micardis), eprosartan (Teveten), and others.
|
Dulse is rich in potassium (103317). Therefore, concomitant use of digoxin with dulse might increase the risk of hyperkalemia. This has not been demonstrated in humans.
|
Dulse is rich in potassium (103317). Therefore, concomitant use of potassium-sparing diuretics with dulse may increase the risk of hyperkalemia. This has not been shown in humans.
Details
Some potassium-sparing diuretics include amiloride (Midamor), spironolactone (Aldactone), and triamterene (Dyrenium), and others.
|
Dulse is rich in iodine (103315,103323). 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 (103315,103323). Theoretically, dulse might interfere with drugs used to treat thyroid dysfunction.
Details
Some thyroid hormones include levothyroxine (Synthroid, Levoxyl, Levothroid), liothyronine sodium (Cytomel), desiccated thyroid (Armor Thyroid), and others.
|
Combining iodine with amiodarone might cause excessively high iodine levels.
Details
|
Iodine might alter the effects of antithyroid drugs.
Details
|
Combining iodine with lithium might have additive hypothyroid effects.
Details
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 (17574). Monitor thyroid function.

Below is general information about the adverse effects of the known ingredients contained in the product Dulse Liquid. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General ...Orally, dulse seems to be well tolerated. No adverse effects have been reported. However, a thorough evaluation of safety outcomes has not been conducted.
General
...Orally, iodine is well tolerated when taken in amounts that do not exceed the tolerable upper intake level (UL) or when used therapeutically with appropriate medical monitoring (2197,7080,7135).
Most Common Adverse Effects:
Orally: Abdominal upset, diarrhea, goiter, headache, hyperthyroidism, hypothyroidism, metallic taste, nausea, rhinorrhea, thyroid adenoma.
Topically: Burns, dermatitis, irritation.
Serious Adverse Effects (Rare):
All ROAs: Hypersensitivity reactions such as anaphylaxis and angioedema.
Dermatologic
...Orally, taking iodine chronically or in large amounts has been reported to cause acneform skin lesions called iododerma (2138).
In one case, a patient developed iododerma after consuming a specific product (Hoxsey's Brown Tonic) containing an unspecified quantity of potassium iodide. After several months of consumption, the patient developed acneform skin lesions on the nose, cheeks, and upper back and presented with a urine iodine level of 7,455,647 ug/L (reference range: 34-523 ug/L). After discontinuation of potassium iodide, the lesions resolved gradually over the course of several weeks (95431).
Topically, iodine may stain skin, irritate tissues, and cause sensitization in some individuals (15,56106). Iodine burns are associated with application of 7% hydroalcoholic solution (15). Povidone-iodine may cause contact dermatitis or irritant reactions in some people. However, patch testing with potassium iodide is usually negative in these patients, indicating that contact dermatitis caused by topical iodine does not indicate a propensity for reaction to oral potassium iodide (93001).
Endocrine
...Prolonged use and/or large oral doses of iodine intake can cause thyroid gland hyperplasia, thyroid adenoma, goiter, and hypothyroidism (15,56013,56089,91397,91398,99793,99795).
In another case report, an infant presented with reversible hypothyroidism at birth because the mother had consumed excessive seaweed soup during and after pregnancy, which resulted in excessive iodine consumption (99795). Iodine has also been linked to rare cases of adverse events. In one case report, a 56-year-old male developed thyrotoxic hypokalemic paralysis thought to be related to excessive intake of iodine (91401).
Topically, using povidone-iodine (PI) 1% solution as a gargle and nasal spray, in addition to intranasal application of PI 10% ointment over 5 days, can precipitate subclinical hypothyroidism, with elevated thyroid stimulating hormone (TSH) and normal thyroid hormone levels. TSH levels seem to normalize about 7-12 days after stopping topical PI application (105877).
Gastrointestinal
...Orally, the commonly reported adverse effects of a saturated solution of potassium iodide (SSKI) are nausea (14%), abdominal pain (14%), metallic taste (4%), and diarrhea (4%) (17561).
These side effects can be minimized by avoiding quick dosage increases (17574). Taking iodine chronically or in large amounts has also been reported to cause soreness in teeth and gums, burning in mouth and throat, increased salivation, swelling of parotid and submaxillary glands, inflammation of the respiratory tract, gastric upset, and diarrhea (15,2138).
Intranasally, applying povidone-iodine 1% solution along with a 10% ointment can cause unpleasant nasal tingling (105877).
Immunologic ...People who are allergic to iodine-containing foods or drugs are sometimes stated to have "iodine allergy", but the actual allergen is another agent such as seafood proteins or radiocontrast media (93001). However, some people can be hypersensitive to iodine when used orally. Symptoms of hypersensitivity can include angioedema, cutaneous and mucosal hemorrhage, fever, arthralgia, lymph node enlargement, eosinophilia, urticaria, erythema, and thrombotic thrombocytopenic purpura (15,17561). Other reported side effects include potassium toxicity, metabolic acidosis, pustular psoriasis, and vasculitis (17574). However, such sensitivity is very rare (93001). Orally, iodine hypersensitivity can cause fatal periarteritis (15).
Neurologic/CNS
...Orally, common side effects of a saturated solution of potassium iodide (SSKI) have included headache (7%) (17561).
Side effects can be minimized by avoiding quick dosage increases (17574).
High intake of iodine may be associated with adverse cognitive outcomes in children. Observational research in children aged 7-14 years has found that those consuming drinking water with iodine concentrations above 900 mcg/L daily, which exceeds the tolerable upper intake level, is associated with a 1.6-point reduction in intelligence level when compared with those consuming water with iodine concentrations below 300 mcg/L (108709).
Ocular/Otic ...Orally, taking iodine chronically or in large amounts has been reported to cause eye irritation and eyelid swelling (15,2138).
Pulmonary/Respiratory ...Orally, common side effects of a saturated solution of potassium iodide (SSKI) included rhinorrhea (11%) (17561). Side effects can be minimized by avoiding quick dosage increases (17574). Taking iodine chronically or in large amounts has also been reported to cause coryza, sneezing, cough, and pulmonary edema (15,2138). Ophthalmically, povidone-iodine 5% solution 3 drops administered in each eye has been reported to slow respiration by about 18 seconds (range 4 to 96 seconds) when compared with saline control in children ages 2-17 years undergoing strabismus surgery (103077).
Renal ...When povidone-iodine was used in renal pelvic instillation sclerotherapy, one patient (2%) had significant flank pain during treatment (55970).
