HelloPharmacist Scorecard of Irish Seamoss by Country Farms
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
Low disclosure
Irish Seamoss by Country Farms contains three active ingredients: burdock, bladderwrack (also called fucus vesiculosus), and Irish Sea Moss. The first two are delivered as a proprietary blend, so you won't see a breakdown of how much of each is in every capsule.
The product also contains inactive ingredients—hypromellose (a capsule material) and bamboo leaf and shoot extract (a filler).
Does it work?
Not established
The evidence backing these ingredients is limited. Burdock has insufficient reliable evidence for acne, aging skin, breast cancer, common cold, and atopic dermatitis (eczema).
Bladderwrack likewise shows insufficient reliable evidence for aging skin, cardiovascular disease, constipation, diarrhea, and indigestion. We hold no effectiveness data for Irish Sea Moss itself.
If you're considering this product for any particular health goal, talk it over with your doctor or pharmacist about what the science actually shows.
How safe is it?
Well-documented data
Burdock is generally well tolerated when eaten as food and used short-term by healthy adults, but human safety data are sparse. Rare serious allergic reactions including anaphylaxis have been reported, as has contact dermatitis, especially with prolonged use of the root oil.
There's also one reported case of liver injury in someone taking an herbal detox tea containing burdock and other ingredients, though it's unclear which ingredient caused it. Burdock should be avoided during pregnancy due to lack of safety data and possible effects on the uterus, and should not be used medicinally while breastfeeding.
Bladderwrack carries more significant safety concerns. Its high iodine content can disrupt thyroid function and the plant may concentrate heavy metals.
It's unsafe during pregnancy and should be avoided while breastfeeding because iodine passes into breast milk and may harm the baby's thyroid. The most common side effects are goiter, hyperthyroidism, and hypothyroidism.
Rare serious effects include thyroid cancer. One case reported palpitations and fainting after taking a weight-loss supplement containing bladderwrack, though it's unclear if bladderwrack alone was responsible.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your doctor or pharmacist if you take lithium—concomitant use can cause hyperthyroidism. Also watch out for antithyroid drugs, thyroid hormone replacements, and amiodarone, which may interact with bladderwrack's iodine content.
If you're on blood thinners or antiplatelet drugs, those should be discussed too. No interactions are documented for the liver enzymes we checked, but theoretically bladderwrack might affect how certain drugs are processed.
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 lithium, antithyroid drugs, thyroid hormone, amiodarone, blood thinners, or antiplatelet drugs, you should check with your doctor or pharmacist before taking this product. The evidence for what this supplement actually does is limited.
Because bladderwrack's iodine content poses real risks—especially if you have thyroid disease or take thyroid medication—talk it over with your own healthcare provider first.

Irish Seamoss by Country Farms Drug Interactions
HelloPharmacist Interaction Report
Irish Seamoss by Country Farms contains burdock and bladderwrack (fucus vesiculosus), both of which have documented interactions with medications.
The most serious concern involves bladderwrack's high iodine content, which can interfere with lithium and cause hyperthyroidism—a particularly important risk if you take lithium for bipolar disorder or other conditions.
Read the full breakdown — every affected drug type, severity by severity
Bladderwrack interacts with several medication types. It may alter how antithyroid drugs, thyroid hormone replacements, and amiodarone work due to its iodine content.
Additionally, it theoretically affects how your body processes drugs broken down by three liver enzymes (CYP2D6, CYP2C9, and CYP3A4 substrates), though these interactions haven't been confirmed in humans. Like burdock, bladderwrack may also increase bleeding risk if you're on blood thinners or antiplatelet drugs.
Burdock raises a moderate concern with blood thinners and antiplatelet medications—in theory, it could boost bleeding risk, though this hasn't been documented in humans. We could not check Irish Sea Moss itself because we hold no data for it.
Altogether, these interactions span 892 individual medications. Use the medication checker on this page to look up any prescriptions you're currently taking before you start this product.

For each ingredient in Irish Seamoss 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.
Bladderwrack
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.
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.
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.
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.
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.
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.
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.
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.
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.
Burdock
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.
