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 19 active ingredients.
  • “Ingredients” is listed as a grouped ingredient — the label gives one combined amount (600 mg) without saying how much of each component you get.

This 19-ingredient product is built around marine algae and nutrient-dense whole-food concentrates. The active ingredients include bladderwrack (a seaweed rich in iodine), astaxanthin (a carotenoid pigment from algae), spirulina species (blue-green algae), chlorella, laminaria (kelp), dulse, ascophyllum nodosum, ecklonia cava, and several others—wakame, dunaliella salina, gigartina red marine algae, phycocyanin, kombu, nannochloropsis gaditana, nori, and fucoxanthin.

The inactive ingredient is gelatin capsules.

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Pregnancy-related iron deficiency — rated "Possibly Effective" (Chlorella) (Natural Medicines).
  • On file: Hypertension — rated "Possibly Effective" (Blue-green Algae) (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Ecklonia Cava) (Natural Medicines).

The evidence we hold for these ingredients' claimed uses is limited. For bladderwrack and laminaria, we have insufficient reliable evidence for aging skin, cardiovascular disease, constipation, diarrhea, and indigestion.

Ascophyllum nodosum shows insufficient evidence for prediabetes, obesity, GERD, and iodine deficiency. Astaxanthin has insufficient evidence for cognitive decline, macular degeneration, aging skin, Alzheimer's disease, athletic performance, and carpal tunnel syndrome.

Blue-green algae (spirulina species) are possibly effective for high blood pressure, but show insufficient evidence for acne, hay fever, iron-deficiency anemia, and arsenic poisoning. Chlorella is possibly effective for pregnancy-related iron deficiency but lacks sufficient evidence for brain tumors, fatty liver disease, depression, and fatigue.

Ecklonia cava is possibly effective for high cholesterol but insufficient for athletic performance, cancer, and diabetes. Most of the product's ingredients lack established effectiveness for their proposed uses.

The evidence, ingredient by ingredient Fucus Vesiculosus Ascophyllum Nodosum Astaxanthin Laminaria Blue-green Algae Dulse Chlorella Ecklonia Cava

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 7 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Several ingredients here warrant caution because of their iodine content and potential contamination. Bladderwrack, laminaria, and other seaweeds can disrupt thyroid function with their variable, sometimes very high iodine levels.

The data also flags concern for heavy metal concentration—laminaria specifically concentrates arsenic from seawater, and a case of arsenic poisoning was reported after months of use. Spirulina quality varies widely and some products carry toxin or heavy metal contamination.

Astaxanthin is generally well tolerated in studies, though long-term safety data are sparse; in trials, higher doses caused severe abdominal pain in two patients. Chlorella is generally well tolerated but allergic reactions including anaphylaxis have been reported.

Common side effects with these algae include abdominal cramping, bloating, diarrhea, headache, nausea, and fatigue—especially in the first two weeks. Pregnancy and lactation: The safety data advise against bladderwrack, laminaria (both species), and laminaria hyperborea due to excess iodine and potential heavy metal content that could harm the fetal or infant thyroid.

Ascophyllum nodosum, astaxanthin, blue-green algae, and chlorella lack sufficient safety data in pregnancy and lactation; talk with your doctor before using if you're pregnant or breastfeeding. Dulse and ecklonia cava have insufficient data on file.

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?
  • 7 of the 8 matched ingredients can interact with medications — Laminaria, Fucus Vesiculosus, Chlorella, Blue-green Algae, Astaxanthin, among others.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,268 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 with your doctor or pharmacist if you're on lithium (risk of high thyroid hormone), thyroid medications or antithyroid drugs (iodine interference), amiodarone (cardiac drug with high iodine), blood thinners like warfarin (vitamin K from chlorella may reduce effectiveness), blood pressure or heart failure drugs that raise potassium (ACE inhibitors, ARBs, potassium-sparing diuretics, or digoxin), diabetes medications (spirulina may lower blood sugar), or immunosuppressants. Also mention photosensitizing drugs if you're on any, since chlorella can increase sun sensitivity.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This is an iodine-rich, algae-based supplement best suited for people without thyroid conditions or kidney issues who aren't taking lithium, thyroid medications, heart rhythm drugs like amiodarone, blood thinners like warfarin, or medications that raise potassium. If you take any prescription medication—especially for your thyroid, heart, or blood pressure—check your specific drugs with your pharmacist or doctor before starting.

Pregnant and breastfeeding people should avoid it due to unpredictable iodine and potential heavy metal content.

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

Astaxanthin2 drug types · 671 drugs

Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP2B6.
In vitro research shows that astaxanthin induces cytochrome CYP2B6 enzyme activity in human hepatocytes. This effect has not been reported in humans.

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

Theoretically, astaxanthin may decrease levels of drugs metabolized by CYP3A4.
In vitro research shows that astaxanthin induces CYP3A4 enzyme activity in human hepatocytes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Astaxanthin full monograph & interactions

Chlorella vulgaris2 drug types · 337 drugs

Photosensitizing Drugs

Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, chlorella might reduce the clinical effects of warfarin.
Chlorella contains significant amounts of vitamin K. There is at least one case report of warfarin therapy becoming sub-therapeutic after initiation of chlorella supplements.

Likelihood Possible Evidence D
Chlorella vulgaris full monograph & interactions

Blue Green Algae3 drug types · 327 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro. However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time.

Likelihood Unlikely Evidence D
Antidiabetes Drugs

Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs. However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes. A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects.

Likelihood Possible Evidence B
Immunosuppressants

Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.

Likelihood Possible Evidence D
Blue Green Algae full monograph & interactions

Purple Dulse7 drug types · 85 drugs

Amiodarine (Cordarone)

Theoretically, combining dulse with amiodarone might cause excessively high iodine levels.
Dulse is rich in iodine, and amiodarone contains 37.3% iodine and can increase iodine levels.

Likelihood Possible Evidence D
Antithyroid Drugs

Theoretically, due to its iodine content, dulse might alter the effects of antithyroid drugs.
Dulse is rich in iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, dulse might increase the risk of hyperkalemia when taken with digoxin.
Dulse is rich in potassium, and digoxin can increase potassium levels in the blood. This interaction has not been demonstrated in humans.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, due to its iodine content, dulse might alter the effects of thyroid hormone.
Dulse is rich in iodine. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Although dulse has been associated with a statistically significant increase in thyroid stimulating hormone (TSH) levels in clinical research, clinically significant increases have not been documented.

Likelihood Possible Evidence D
Ace Inhibitors (Aceis)

Theoretically, dulse might increase the risk of hyperkalemia when taken with ACEIs.
Dulse is rich in potassium. ACEIs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels. However, using these drugs while consuming dulse in quantities that provide larger amounts of potassium daily might increase the risk of hyperkalemia. Additionally, in vitro research suggests that dulse protein hydrolysates inhibit the activity of ACE. However, these effects have not been demonstrated in humans.

Likelihood Possible Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, dulse might increase the risk of hyperkalemia when taken with ARBs.
Dulse is rich in potassium. ARBs block the actions of the renin-angiotensin-aldosterone system and reduce potassium excretion. Concomitant use of these drugs with moderate dietary potassium intake (about 3775-5200 mg daily) does not increase serum potassium levels. However, using these drugs while consuming dulse in quantities that provide higher amounts of potassium daily might increase the risk of hyperkalemia. Additionally, in vitro research suggests that dulse protein hydrolysates inhibit the activity of angiotensin converting enzyme (ACE). However, these effects have not been demonstrated in humans.

Likelihood Possible Evidence D
Potassium-Sparing Diuretics

Theoretically, dulse might increase the risk of hyperkalemia when taken with potassium-sparing diuretics.
Dulse is rich in potassium, and potassium-sparing diuretics can increase potassium levels in the blood. This interaction has not been shown in humans.

Laminaria digitata6 drug types · 69 drugs

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.

Ormus Gold Ocean Nectar by Ormus Minerals: Common Questions

Does Ormus Gold Ocean Nectar by Ormus Minerals interact with any medications?
Yes. Based on its ingredients, Ormus Gold Ocean Nectar has a known interaction with 1,267 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ormus Gold Ocean Nectar contains 19 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.
Does this have iodine in it?
Yes—several ingredients (bladderwrack, laminaria, dulse, ascophyllum nodosum, ecklonia cava) contain significant iodine. The exact amount can vary widely between batches and manufacturers, which is why anyone on thyroid or heart medications should check with their doctor first.
Can I take this if I'm pregnant or breastfeeding?
The data advise against it during pregnancy and breastfeeding. High iodine can interfere with the baby's thyroid development and function, and some ingredients may concentrate heavy metals. Talk with your doctor about whether it's right for you.
What side effects does this product cause?
The most common are digestive—abdominal cramps, bloating, diarrhea, nausea, and fatigue, especially in the first two weeks. Chlorella can cause photosensitivity (sun sensitivity). Rare but serious allergic reactions, including anaphylaxis, have been reported with some algae ingredients.
Will this help with my thyroid?
We don't have reliable evidence that this product helps thyroid function. In fact, the high iodine content can disrupt the thyroid in people with existing thyroid conditions or in those taking thyroid medications, making it potentially harmful rather than helpful.
Can this help with weight loss or blood sugar?
Some ingredients like spirulina may theoretically have modest effects on blood sugar or weight, but the evidence we hold is insufficient to call it effective for either. If you have diabetes, spirulina could lower blood sugar further when combined with medications, so check with your doctor.
Is this contaminated with heavy metals?
The data flag concern for heavy metal contamination, particularly arsenic in laminaria (kelp), which concentrates it from seawater. Product quality varies, and one case of arsenic poisoning was reported after months of use. There's no guarantee your batch is free of contamination.
