HelloPharmacist Scorecard of Sea Moss by Ambrosia Collective

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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: sea moss, a type of seaweed that's a natural source of iodine and minerals. The capsule also holds cellulose and brown rice flour as inactive ingredients that help form and fill out the capsule.

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 — see Sea Moss's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Thyroid support, digestive aid, energy boost.
  • We looked for evidence on: Fatigue, Iodine deficiency, Thyroid function, Digestive health.
  • The closest evidence on file: Sea Moss is rated "Insufficient Reliable Evidence To Rate" for Fatigue (Natural Medicines).
  • Also on file: Sea Moss is rated "Insufficient Reliable Evidence To Rate" for Iodine deficiency.

The evidence we hold doesn't establish whether sea moss works for fatigue, muscle strength, chronic pain, quality of life, or iodine deficiency — the data just isn't there yet to say it does or doesn't. If you're considering this for one of those reasons, talk with your pharmacist about what the current research actually supports.

The evidence, ingredient by ingredient Sea Moss

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 1 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.

Sea moss is generally seen as a food, but here's the catch: the amount of iodine and any heavy metals in it can vary widely depending on where it's sourced and how it's processed, so caution is warranted. One observational study reported that some people experienced constipation or diarrhea.

The safety data advises against using sea moss during pregnancy because iodine levels are unpredictable and excess iodine can affect the baby. For the same reason — too little safety data and the risk to a nursing infant — it's best avoided while breastfeeding.

Side effects, ingredient by ingredient Sea Moss

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 — Sea Moss.
  • The most serious interaction on file is rated Moderate.
  • For scale: 22 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.

Check sea moss with your pharmacist if you take antithyroid drugs, thyroid hormone replacement (like levothyroxine), or amiodarone (Cordarone). All three can be affected by the iodine in this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Sea moss may appeal to you if you're looking for a natural mineral source, but it's mainly a medication concern, not an ingredient to use lightly. If you take any thyroid or heart medication, you need to check this with your pharmacist first — the iodine content really matters here.

Sea Moss3 drug types · 22 drugs

Amiodarone (Cordarone)

Theoretically, combining sea moss with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with sea moss, which contains approximately 4-7 mcg of iodine per gram, might increase the risk of adverse effects from iodine, including altered thyroid function.

Likelihood Possible Evidence D
Antithyroid Drugs

Due to its iodine content, sea moss might alter the effects of antithyroid drugs.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of antithyroid drugs.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, sea moss might alter the effects of thyroid hormone.
Sea moss contains approximately 4-7 mcg of iodine per gram. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking sea moss could theoretically alter the effects of thyroid hormone.

Sea Moss by Ambrosia Collective: Common Questions

Does Sea Moss by Ambrosia Collective interact with any medications?
Yes. Based on its ingredients, Sea Moss has a known interaction with 22 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 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.
Does sea moss really give you energy?
The data we have doesn't establish whether it does — there's not enough reliable evidence to say. If fatigue is your main concern, your pharmacist can help you figure out what might actually help.
What are the side effects?
One study reported that some people had constipation or diarrhea. Beyond that, the big safety flag is iodine and potential heavy-metal content, which can vary a lot from batch to batch.
Is it safe to take while pregnant?
No — the safety data advises against it during pregnancy because iodine levels in sea moss are unpredictable and excess iodine can affect the baby. Talk with your doctor or pharmacist about whether you need an iodine source during pregnancy.
Can I take it while breastfeeding?
The safety data advises against it — there's too little data to know it's safe, and excess iodine can reach a nursing baby. Ask your pharmacist about safer alternatives if you're concerned about iodine intake.
What is sea moss exactly?
It's a type of seaweed that naturally contains iodine and minerals. In this product, it comes in capsule form.
