HelloPharmacist Scorecard of Ocean Plant Extract by Body Ecology

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 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: laminaria extract, a concentrated form of a brown seaweed. Laminaria is included for its mineral content, particularly iodine and potassium.

The capsule also holds rice extract and a vegetarian capsule shell as inactive ingredients.

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

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: detoxification and thyroid support.
  • We looked for evidence on: thyroid function, iodine deficiency, detoxification.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for laminaria is sparse. Our data shows it rated as possibly ineffective for two obstetric uses — preventing miscarriage and aiding labor.

For weight loss, high blood pressure, cancer, and acute radiation exposure, the evidence isn't established well enough to rate one way or the other.

The evidence, ingredient by ingredient Laminaria

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.

Laminaria concentrated from seaweed is generally well tolerated orally when the iodine content is controlled, but many supplements contain very high and variable amounts of iodine that can affect your thyroid. The seaweed also concentrates arsenic from ocean water; one person taking a laminaria supplement for several months developed arsenic poisoning with headache, weakness, memory loss, rash, nail damage, diarrhea, and vomiting.

Arsenic levels vary between batches and regions. In pregnancy, excess iodine can harm the developing fetal thyroid, so kelp supplements should be avoided unless your doctor directs otherwise.

If you're breastfeeding, high-dose iodine passes into breast milk and may affect your infant's thyroid, so avoid concentrated supplements. If you're considering this product while pregnant or nursing, talk with your doctor or pharmacist first.

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 — Laminaria.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications.
  • For scale: 69 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, double-check any potassium-sparing diuretics, ACE inhibitors, or heart medications like digoxin or amiodarone. If you're on thyroid hormone replacement or antithyroid drugs, that's another critical check.

The iodine and potassium in laminaria can interfere with how these work.

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.

This supplement may appeal to people looking for a seaweed-based mineral source, but it's not for everyone. If you take any heart, blood pressure, or thyroid medication — or a water pill — you need to check your drugs with a pharmacist first.

Pregnant or breastfeeding? Steer clear unless your doctor says otherwise.

Run this one by your pharmacist before you start.

Ace Inhibitors (Aceis)

Theoretically, laminaria might increase the risk of hyperkalemia when taken with ACEIs.
Laminaria contains potassium.

Likelihood Possible Evidence D
Amiodarone (Cordarone)

Theoretically, combining laminaria with amiodarone might cause excessively high iodine levels.
Amiodarone contains 37.3% iodine and can increase iodine levels. Concomitant use with laminaria supplements, some of which may contain as much as 1000 mcg iodine, might increase the risk of adverse effects from iodine, including altered thyroid function.

Likelihood Possible Evidence D
Antithyroid Drugs

Due to its iodine content, laminaria might alter the effects of antithyroid drugs.
Some laminaria supplements contain up to 1000 mcg of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking laminaria could theoretically alter the effects of antithyroid drugs.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, laminaria might increase the risk of hyperkalemia, which could increase the effects and adverse effects of digoxin.
Laminaria contains potassium.

Likelihood Possible Evidence D
Potassium-Sparing Diuretics

Theoretically, laminaria might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Laminaria contains potassium.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, laminaria might alter the effects of thyroid hormone.
Some laminaria supplements contain up to 1000 mcg of iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking laminaria could theoretically alter the effects of thyroid hormone.

Ocean Plant Extract by Body Ecology: Common Questions

Does Ocean Plant Extract by Body Ecology interact with any medications?
Yes. Based on its ingredients, Ocean Plant Extract has a known interaction with 69 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ocean Plant Extract 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.
Can I take this if I'm on thyroid medication?
Not without checking first. Laminaria contains up to 1,000 micrograms of iodine, which can change how your thyroid hormone replacement or antithyroid drugs work. Talk with your pharmacist or doctor before starting.
Is laminaria safe in pregnancy?
No. The safety data advises against it in pregnancy because high iodine can harm the fetal thyroid. If you're pregnant or thinking about becoming pregnant, speak with your doctor before using this product.
What are the side effects of this product?
When iodine content is controlled, laminaria is generally well tolerated orally. However, laminaria concentrates arsenic from seawater, and one person on a laminaria supplement for several months developed arsenic poisoning with fatigue, memory loss, rash, nail damage, and vomiting. Arsenic levels can vary between batches and depend on where the seaweed was harvested.
Is there evidence this works for weight loss or blood pressure?
Not yet. The evidence for laminaria on weight loss and high blood pressure isn't established enough to say whether it helps or not.
Can I take this with a water pill or blood pressure medication?
You need to check with your pharmacist first. Laminaria is high in potassium, which can raise your blood potassium to unsafe levels when combined with certain blood pressure drugs or water pills that keep potassium in your body.
Can I take this while breastfeeding?
The safety data advises against it. High amounts of iodine pass into breast milk and may affect your infant's thyroid. Talk with your doctor or pharmacist about whether this product is right for you.
