HelloPharmacist Scorecard of Organic Dulse Seaweed Strawberry Flavor by TerraVita

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
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.

This product contains one active ingredient: dulse seaweed glycerite liquid extract. Dulse is a type of edible red seaweed that's been used as a whole food for centuries and is naturally high in iodine and potassium.

The extract is suspended in glycerin (a sweet liquid used as a preservative and base) and flavored with strawberry. That's it—no added fillers or binders beyond what you see here.

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 Dulse product and its label doesn't state a use — see Dulse'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 evidence on dulse seaweed for lowering cholesterol or treating iodine deficiency is insufficient to rate in our data. We can't tell you whether this product works for those purposes based on what we have on file.

If either of those is why you're considering it, talk it over with your doctor or pharmacist about whether the evidence supports it for you.

The evidence, ingredient by ingredient Dulse

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Dulse is generally well tolerated as a whole food in normal amounts. However, as a concentrated supplement, it carries real caution flags.

The iodine and potassium levels in supplements can be unpredictable and potentially high—higher than what you'd get eating seaweed at the dinner table. We don't have much safety data on long-term use of dulse supplements at high doses.

During pregnancy or breastfeeding, there isn't enough information to know whether this product is safe; excess iodine can pass into breast milk. Talk with your doctor before using it if you're pregnant, planning to become pregnant, or nursing.

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 — Dulse.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 85 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 this product, check with your doctor or pharmacist if you take thyroid hormone replacements or antithyroid drugs (worst risk), amiodarone, digoxin, potassium-sparing diuretics, ACE inhibitors, or ARBs. The dulse's high iodine and potassium content could interfere with how these medications work.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Dulse seaweed is a traditional food, but this supplement form—with its concentrated iodine and potassium—is not for everyone. If you take any thyroid medication, heart medication (especially digoxin or amiodarone), water pills, or blood pressure drugs, run this by your doctor or pharmacist first.

It's also worth checking if you're pregnant, nursing, or planning to become pregnant.

Dulse Seaweed Glycerite Liquid Extract7 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.

Organic Dulse Seaweed Strawberry Flavor by TerraVita: Common Questions

Does Organic Dulse Seaweed Strawberry Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Organic Dulse Seaweed Strawberry Flavor has a known interaction with 85 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Dulse Seaweed Strawberry Flavor 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.
Is dulse seaweed safe to eat if I take thyroid medication?
Dulse is naturally high in iodine, and iodine can alter how thyroid medications work. This product is a concentrated supplement, not food amounts—so caution applies. Talk with your doctor or pharmacist before starting it if you're on thyroid medication; they can advise whether it's okay for you specifically.
What's the difference between eating dulse as food and taking this supplement?
Food portions of dulse contain much less iodine and potassium than a concentrated supplement extract. This liquid is a supplement dose, so the amounts are higher and less predictable. If you're just looking for culinary seaweed, this isn't the same thing.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to say yes or no. Excess iodine can pass into breast milk, and we don't know enough about dulse supplement use in pregnancy. Talk with your doctor before taking this if you're pregnant, planning to become pregnant, or nursing.
Does this product actually lower cholesterol or treat iodine deficiency?
We don't have reliable evidence in our data that it does either. If that's why you're interested in it, ask your doctor or pharmacist whether dulse supplements are backed by solid research for your situation.
What are the side effects of dulse seaweed?
Our data doesn't list specific side effects reported in trials. Dulse is generally well tolerated as a food, but the safety information for supplements at higher doses is limited. If you experience any unexpected reactions, let your doctor or pharmacist know.
