HelloPharmacist Scorecard of Sea Moss+ by NutriFlair

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

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 3 of its 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (1,600 mg) without saying how much of each component you get.

Sea Moss+ contains 3 active ingredients: organic Irish moss powder, bladderwrack extract powder (from Fucus vesiculosus seaweed), and burdock root extract powder. The product is housed in a vegetable capsule.

Bladderwrack and burdock are both traditional seaweed and root plants used in herbal medicine. Bladderwrack is particularly high in iodine, which plays a role in thyroid function, while burdock has been used historically in foods and folk remedies.

The exact amounts of each ingredient aren't broken out on the label — they're combined in a proprietary blend.

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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold doesn't establish that Sea Moss+ works for any of the conditions it may be marketed for. For bladderwrack, we rate the evidence insufficient for aging skin, heart disease, constipation, diarrhea, and indigestion.

For burdock, evidence is similarly insufficient for acne, aging skin, breast cancer, colds, and eczema. This doesn't mean these ingredients don't work — just that reliable human studies backing their use aren't in our data.

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.

Bladderwrack is the safety concern here. Because of its high and variable iodine content, it can disrupt your thyroid and may concentrate heavy metals from seawater.

The product is not safe in pregnancy or while breastfeeding — excess iodine passes into breast milk and can affect your baby's thyroid, and pregnancy safety data advise against it. When taken orally, bladderwrack may cause goiter (enlarged thyroid), high thyroid function (hyperthyroidism), or low thyroid function (hypothyroidism).

Rare serious side effects include thyroid cancer. There's also a reported case of heart palpitations and fainting in someone taking a weight-loss blend containing bladderwrack, though it's unclear whether bladderwrack alone was responsible.

Burdock is generally well tolerated as a food and short-term supplement in healthy adults, though allergic reactions including contact dermatitis and rarely anaphylaxis have been reported, and one case of liver damage was linked to a burdock-containing detox tea.

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.

Before taking Sea Moss+, check with your pharmacist or doctor if you're on lithium (moderate-severity risk of high thyroid levels), antithyroid drugs, amiodarone, or thyroid hormone replacement (all moderate-severity due to iodine). Also confirm if you're taking blood thinners or antiplatelet drugs like warfarin or aspirin (moderate-severity bleeding risk from burdock, minor-severity theoretical risk from bladderwrack).

If you're on other prescription medications, use the interaction checker on this page to see your exact drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Sea Moss+ is only for adults without thyroid disease, and absolutely not for pregnancy or breastfeeding. If you take lithium, any thyroid medication, amiodarone, blood thinners, or certain other prescription drugs, you need to check with your doctor or pharmacist before starting — the iodine content creates real risks.

If your thyroid is normal and you're not on interacting drugs, talk it over with your own healthcare provider to see if this supplement makes sense for you.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in 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.

Bladderwrack Extract, Powder9 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

Burdock Root Extract, Powder1 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.

Sea Moss+ by NutriFlair: Common Questions

Does Sea Moss+ by NutriFlair interact with any medications?
Yes. Based on its ingredients, 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?
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 Sea Moss+ safe to take while pregnant or breastfeeding?
No. The safety data advise against it during pregnancy because of excess iodine and possible heavy metal content. While breastfeeding, you should also avoid it — iodine passes into breast milk and may affect your baby's thyroid. Talk with your doctor or pharmacist before taking this product if you're pregnant, planning pregnancy, or nursing.
What does bladderwrack do in this product?
Bladderwrack is a seaweed rich in iodine, traditionally used for thyroid and general wellness support. In this product it's listed as an extract powder. The evidence we hold doesn't establish it works for any specific condition — the rated uses (aging skin, heart disease, constipation, diarrhea, indigestion) all have insufficient evidence.
Can Sea Moss+ cause thyroid problems?
Yes. Bladderwrack's high iodine content can cause or worsen goiter, hyperthyroidism (overactive thyroid), and hypothyroidism (underactive thyroid), depending on your individual history. This is especially risky if you're already taking thyroid medications, antithyroid drugs, or lithium. If you have any thyroid condition, check with your doctor before taking this.
Will Sea Moss+ make my blood thinner?
Not directly, but it may increase your bleeding risk if you're already taking blood thinners or antiplatelet drugs. This is a theoretical concern from lab studies — it hasn't been reported in actual patients yet. If you're on warfarin, aspirin, or similar drugs, ask your pharmacist before starting this supplement.
Does this product have any fillers or inactive ingredients?
Yes, the capsule itself is made from vegetable material. That's the only inactive ingredient listed on the label — the rest is the proprietary blend of the three active ingredients.
What's the difference between sea moss and bladderwrack in this product?
Sea moss (Irish moss) and bladderwrack are both seaweeds, but they're different species. The facts here don't break out their individual roles or how much of each is in the blend. Both are high in iodine, which is why the thyroid safety concerns apply to the whole product.
