HelloPharmacist Scorecard of Ocean Nectar Marine Phytoplankton & Probiotic Blend by Ormus Minerals

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

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 24 active ingredients.
  • “Probiotic Blend” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “Ingredients” is listed as a grouped ingredient — the label gives one combined amount (600 mg) without saying how much of each component you get.

Ocean Nectar contains 24 ingredients, with the active components being a probiotic blend—Lactobacillus acidophilus, Bifidobacterium longum, Bifidobacterium bifidum, Bacillus subtilis, and Enterococcus faecium—plus marine phytoplankton and algae sources including Hawaiian Spirulina pacifica, Blue-green Algae, Spirulina platensis, Chlorella vulgaris, and several kelp and seaweed species (Ascophyllum nodosum, Laminaria digitata, Laminaria hyperborea, Purple Dulse, Ecklonia cava). The blend also includes Astaxanthin (a carotenoid), Fulvic Acid Minerals, Phycocyanin, and Phyconutrient extracts.

The capsule itself is gelatin.

Does it work?

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: Antibiotic-associated diarrhea — rated "Possibly Effective" (Bacillus Subtilis) (Natural Medicines).
  • On file: Bacterial vaginosis — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Helicobacter pylori — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Hypercholesterolemia — rated "Possibly Effective" (Ecklonia Cava) (Natural Medicines).
  • On file: Hypertension — rated "Possibly Effective" (Blue-green Algae) (Natural Medicines).

The evidence for most of these ingredients remains limited. Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis.

Bacillus subtilis is possibly effective for antibiotic-associated diarrhea. Bifidobacterium bifidum is possibly effective for irritable bowel syndrome and respiratory tract infections.

Blue-green algae (spirulina) is possibly effective for high blood pressure. Ecklonia cava is possibly effective for high cholesterol.

For most other conditions listed—cognitive decline, allergies, anxiety, asthma, athletic performance, and many others—the evidence we hold is insufficient to establish whether these ingredients work. No effectiveness data are on file for several ingredients including Dunaliella salina, Phycocyanin, Kombu, Fucoxanthin, and Saccharomyces cerevisiae.

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 12 of the 14 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 13 of 14.
  • General safety write-ups exist for 14 of 14.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

The live bacteria in this product are generally well tolerated in healthy people, but a few cautions apply. Gastrointestinal side effects—abdominal pain, bloating, flatulence, diarrhea, and constipation—have been reported, though they're uncommon.

Rare cases of bacterial bloodstream infection from the probiotic species have occurred in critically ill or severely immune-compromised patients. The seaweed components carry iodine, which varies by source and may affect the thyroid; they may also concentrate arsenic or other heavy metals depending on where they were harvested.

Chlorella has caused photosensitivity (sun sensitivity) in some people. Astaxanthin and blue-green algae may cause abdominal discomfort or digestive upset.

Allergic reactions including anaphylaxis have been reported with blue-green algae and chlorella, though they're rare. Pregnancy and breastfeeding safety data are incomplete or advise against use for most ingredients; talk with your doctor before use if you're pregnant or nursing.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 12 of the 14 matched ingredients can interact with medications — Laminaria, Brewer's Yeast, Lactobacillus Acidophilus, Chlorella, Blue-green Algae, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications; heart-rhythm medications; lithium.
  • For scale: 1,348 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 these medication types before adding this product: thyroid and antithyroid drugs (Ascophyllum, kelp, Purple Dulse, Ecklonia cava contain iodine); blood pressure and heart medications including ACE inhibitors, ARBs, potassium-sparing diuretics, and digoxin (kelp and Purple Dulse contain potassium); amiodarone (seaweed iodine content); blood thinners and antiplatelet drugs (fulvic acid and chlorella); warfarin specifically (chlorella's vitamin K); antibiotics (all probiotic species); immune-suppressing drugs (blue-green algae and fulvic acid); diabetes medications (blue-green algae); and medications metabolized by CYP3A4 or CYP2B6 liver enzymes (astaxanthin). Altogether, these interactions span 1,293 individual medications.

The bottom line

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

This is a multi-ingredient blend aimed at gut and overall wellness through probiotics and marine nutrients. If you take any blood pressure medication, heart medication, thyroid medication, blood thinner, or diabetes drug, you'll need to check your exact prescriptions with the tool on this page before starting.

The live organisms are risky if you're seriously ill or immune-compromised. Healthy people with no medication conflicts may tolerate it, but the evidence that it actually does what it claims remains weak to insufficient for most uses.

For each ingredient in Ocean Nectar Marine Phytoplankton & Probiotic Blend 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.

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

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

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

Probiotic Blend1 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and L. acidophilus preparations by at least two hours.

Likelihood Probable Evidence D

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.

Likelihood Possible Evidence D

Laminaria hyperborea6 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.

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.

Likelihood Possible Evidence D

Ascophyllum nodosum3 drug types · 22 drugs

Amiodarone (Cordarone)

Theoretically, combining Ascophyllum nodosum with amiodarone might cause excessively high iodine levels.
Ascophyllum nodosum contains iodine, although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide. 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, Ascophyllum nodosum might alter the effects of antithyroid drugs.
Ascophyllum nodosum contains iodine, although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history. Taking Ascophyllum nodosum while using antithyroid drugs could alter the effects of the antithyroid drugs.

Likelihood Possible Evidence D
Thyroid Hormone

Due to its iodine content, Ascophyllum nodosum might alter the effects of thyroid hormone.
Ascophyllum nodosum contains iodine, although the bioavailability of iodine from Ascophyllum nodosum is lower than that of potassium iodide. Iodine in high doses has been reported to cause both hyperthyroidism and hypothyroidism, depending on the individual's past medical history.

Yes. Based on its ingredients, Ocean Nectar Marine Phytoplankton & Probiotic Blend has a known interaction with 1,347 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ocean Nectar Marine Phytoplankton & Probiotic Blend contains 17 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 this safe to take if I'm pregnant or breastfeeding?
Safety data for most of these ingredients are incomplete or advise against use during pregnancy and breastfeeding—especially the seaweed components because of iodine content, and fulvic acid. Talk with your doctor or pharmacist about whether this product is right for you before taking it.
Can I take this at the same time as my antibiotic?
No. The live probiotic organisms in this product may be killed by antibiotics taken at the same time. Wait a few hours between your antibiotic dose and this supplement, or better yet, ask your pharmacist about the best timing for your specific antibiotic.
Will this help my IBS or digestion?
Lactobacillus acidophilus and Bifidobacterium bifidum are possibly effective for irritable bowel syndrome based on the evidence we hold. Bacillus subtilis is possibly effective for antibiotic-associated diarrhea. Results vary from person to person, and the data aren't conclusive.
What are the most common side effects?
Gastrointestinal symptoms—bloating, flatulence, abdominal discomfort, and changes in bowel movements—are the most common, especially when you first start. These are usually mild and temporary. Allergic reactions are rare but possible, particularly with the algae components.
Does this product have fillers or other inactive ingredients?
Yes, the capsules are made of gelatin. That's the only inactive ingredient listed on the facts we have.
Can this affect how my thyroid medication works?
Yes. Several ingredients—the kelp, seaweed, and Ascophyllum nodosum—contain significant amounts of iodine, which can interfere with thyroid and antithyroid drugs. If you take thyroid medication or an antithyroid drug, check with your pharmacist before starting this product.
