HelloPharmacist Scorecard of Irish Sea Moss by Her Own

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.

From our pharmacy team — supplement deep dive

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 0 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (500 mg) without saying how much of each component you get.

Her Own Irish Sea Moss is a 3-ingredient capsule. The active ingredients are burdock, bladderwrack (fucus vesiculosus), and Irish sea moss.

The capsules also contain inactive ingredients: hypromellose (a capsule material), bamboo shoot extract, and bamboo leaf extract.

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: thyroid health, metabolism and detoxification.
  • We looked for evidence on: Hypothyroidism, Iodine deficiency, Metabolic syndrome, Obesity, Constipation, Weight management — and 3 related terms.
  • The closest evidence on file: Burdock is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).
  • Also on file: Burdock is rated "Insufficient Reliable Evidence To Rate" for Metabolic syndrome.
  • Also on file: Fucus Vesiculosus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Hypothyroidism, Obesity, Metabolic syndrome, and more.

The evidence for what burdock and bladderwrack do isn't established in the data we hold. Burdock has been tested for acne, aging skin, breast cancer, common cold, and eczema — all came back with insufficient reliable evidence to rate.

Bladderwrack's effectiveness for aging skin, heart disease, constipation, diarrhea, and indigestion also lacks sufficient evidence. We have no effectiveness data on file for Irish sea moss itself.

The evidence, ingredient by ingredient Burdock Fucus Vesiculosus

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Burdock is generally well tolerated when eaten as food and used short-term in healthy adults, though human safety data are limited. Serious allergic reactions including anaphylaxis are rare.

One case of liver injury was reported after taking a herbal blend containing burdock, but it's unclear if burdock was the culprit. Contact dermatitis has occurred, especially with prolonged use of burdock root oil or plasters.

Bladderwrack may be unsafe orally because of its high iodine content, which can cause goiter, overactive thyroid (hyperthyroidism), or underactive thyroid (hypothyroidism). One case of thyroid cancer was reported.

A young adult taking a weight loss supplement containing bladderwrack developed heart palpitations and abnormal heart rhythm, though other ingredients in that product may have been responsible. Bladderwrack is not safe during pregnancy or breastfeeding due to excess iodine and possible heavy metal concentration.

Side effects, ingredient by ingredient Burdock Fucus Vesiculosus

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?
  • 2 of the 2 matched ingredients can interact with medications — Burdock, Fucus Vesiculosus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 892 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.

Double-check with your doctor or pharmacist if you take thyroid medications, antithyroid drugs, lithium, or amiodarone — bladderwrack's iodine content could significantly affect how these work. Blood thinners and antiplatelet drugs (like warfarin or aspirin) may carry a higher bleeding risk.

Several liver enzymes that metabolize medications — CYP2D6, CYP2C9, and CYP3A4 — may be affected by bladderwrack, though no human cases are documented.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

If you take any thyroid medication, lithium, amiodarone, blood thinners, or antiplatelet drugs, talk with your doctor or pharmacist before starting this product — the interactions could affect how these medications work. Burdock and bladderwrack are used traditionally but have limited modern safety data and no proven effectiveness for the conditions they're marketed for.

Run your medications through the checker on this page to see if there are specific concerns.

Each ingredient & the kinds of drugs it affects

For each ingredient in Irish Sea Moss 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.

Bladderwrack9 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.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Fucus vesiculosus might alter the effects of thyroid hormone.
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 thyroid hormone could alter the effects of thyroid hormone.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, taking Fucus vesiculosus with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro evidence suggests that a constituent of Fucus vesiculosus, known as fucoidan, has anticoagulant effects. However, in clinical research, fucoidan does not seem to have significant anticoagulant activity when taken orally, possibly due to poor absorption.

Likelihood Unlikely Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C8 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C8. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2C9 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP2C9. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP2D6 substrates might alter the effects of these substrates.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, both inhibits and induces CYP2D6. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, concomitant use of Fucus vesiculosus with CYP3A4 substrates might increase the risk for adverse effects.
In vitro research shows that fucoidan, a constituent of Fucus vesiculosus, inhibits CYP3A4. This interaction has not been reported in humans.

Likelihood Possible Evidence D

Burdock1 drug type · 122 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, taking burdock with anticoagulant or antiplatelet drugs might increase the risk of bleeding.

In vitro research shows that lignans from burdock reduce rabbit platelet aggregation by inhibiting platelet activating factor. This interaction has not been reported in humans.

Irish Sea Moss by Her Own: Common Questions

Does Irish Sea Moss by Her Own interact with any medications?
Yes. Based on its ingredients, Irish Sea Moss has a known interaction with 891 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Irish Sea Moss contains 3 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.
Is it safe to take this while pregnant or breastfeeding?
No. Burdock should be avoided in medicinal amounts during pregnancy due to lack of safety data and possible effects on the uterus, and shouldn't be used while breastfeeding. Bladderwrack is not safe in pregnancy because of its iodine and possible heavy metal content, and should be avoided while breastfeeding because iodine passes into breast milk and may affect the baby's thyroid. Talk with your doctor or pharmacist for personalized advice.
What does burdock do in this product?
We don't have established effectiveness data for burdock for any condition in the information we hold. It's been used traditionally and tested for acne, aging skin, breast cancer, common cold, and eczema, but the evidence isn't strong enough to rate.
What about the Irish sea moss ingredient — does it interact with any drugs?
We hold no interaction data for Irish sea moss itself, so we can't check it. Use the medication search tool on this page to confirm your specific drugs aren't affected by the burdock and bladderwrack in the product.
Can burdock or bladderwrack cause side effects?
Burdock is generally well tolerated but rare serious allergic reactions can occur, and contact dermatitis has been reported with prolonged root oil use. Bladderwrack may be unsafe orally due to its iodine — it can cause goiter, overactive thyroid, underactive thyroid, and in one rare case, thyroid cancer. One person taking a weight loss supplement with bladderwrack developed dangerous heart rhythm problems, though other ingredients may have been involved.
Is there anything I should know about how much iodine is in this?
Bladderwrack contains high concentrations of iodine, which can disrupt thyroid function. If you have thyroid disease, take thyroid medication, or are sensitive to iodine, you should discuss this product with your doctor or pharmacist before starting.
Has this product been proven to work?
The evidence we hold shows insufficient reliable data for burdock to rate its effectiveness for acne, aging skin, breast cancer, common cold, or eczema. Bladderwrack also lacks sufficient evidence for the conditions it's been tested for. We have no effectiveness data on file for Irish sea moss itself.
