HelloPharmacist Scorecard of Marine Greens by Garden Greens
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.
What’s inside
Low disclosure
Garden Greens Marine Greens contains 9 ingredients, including bladderwrack, dulse, and spirulina blue-green algae as active components, alongside nori, wakame, kombu, and other seaweed extracts. These are marine plants (seaweeds and algae) traditionally used in whole-food supplements for nutritional support.
The product also contains inactive ingredients—cellulose, magnesium stearate, and silica—which are common capsule fillers and binders.
Does it work?
Not established
The evidence for Marine Greens' ingredients is limited. For bladderwrack, we have insufficient reliable evidence to rate its effectiveness for aging skin, heart health, constipation, diarrhea, or indigestion.
Dulse similarly lacks sufficient evidence for cholesterol or iodine-deficiency claims. Spirulina blue-green algae shows possibly effective evidence for high blood pressure, but insufficient evidence for acne, allergies, anemia, or arsenic poisoning.
Overall, these ingredients are not established as effective treatments for any specific condition in the data we hold.
How safe is it?
Well-documented data
Bladderwrack may be unsafe when taken by mouth due to its iodine content; reported side effects include goiter, an overactive thyroid (hyperthyroidism), an underactive thyroid (hypothyroidism), and rarely thyroid cancer. Dulse is generally safe as a food but concentrated supplements carry unpredictable iodine levels and limited safety data.
Spirulina blue-green algae is generally well tolerated orally, though common side effects include abdominal cramps, bloating, diarrhea, dizziness, fatigue, gas, headache, nausea, and vomiting; allergic reactions including rash, swelling, and rarely anaphylaxis have been reported. Quality varies widely—some products contain heavy metals or toxins.
During pregnancy, bladderwrack is considered possibly unsafe due to excess iodine; during breastfeeding, iodine from bladderwrack passes into breast milk and may affect the baby's thyroid. Dulse and spirulina safety during pregnancy and breastfeeding is not clearly established in the data we hold.
Meds to double-check
Moderate interaction found
Before taking Marine Greens, check with your doctor or pharmacist if you take thyroid hormone replacements, antithyroid drugs, lithium, amiodarone, digoxin, blood thinners (anticoagulants or antiplatelet drugs), diabetes medications, immunosuppressants, ACE inhibitors, ARBs, potassium-sparing diuretics, or any drugs broken down by your liver's CYP2D6, CYP2C9, or CYP3A4 enzymes. Altogether, these interactions span 1,089 individual medications.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.
Marine Greens is a seaweed-based supplement with significant interactions involving thyroid medications, heart drugs, and blood pressure medications—especially if you take lithium, thyroid hormone, antithyroid drugs, amiodarone, digoxin, or blood thinners. Its ingredients are generally well tolerated as food but carry unpredictable iodine and potassium levels as supplements, and quality varies.
Talk with your doctor or pharmacist before starting this product, particularly if you have a thyroid condition or take any prescription medications.

Marine Greens by Garden Greens Drug Interactions
HelloPharmacist Interaction Report
Garden Greens Marine Greens interacts with medications through its bladderwrack and dulse content.
The most serious interactions are Moderate and involve thyroid function: bladderwrack and dulse both contain high iodine and may alter how thyroid hormone replacements and antithyroid drugs work, and either may cause excessive iodine levels when combined with amiodarone (a heart rhythm medication). Bladderwrack also carries a Moderate risk with lithium, which has resulted in an overactive thyroid (hyperthyroidism) in at least one reported case.
Read the full breakdown — every affected drug type, severity by severity
Bladderwrack poses additional Moderate concerns with digoxin (a heart medication), as dulse—rich in potassium—may raise potassium levels dangerously when paired with it. Both ingredients also interact with blood pressure medications: dulse may raise potassium levels (a problem with ACE inhibitors, ARBs, and potassium-sparing diuretics), and bladderwrack may theoretically affect how your liver breaks down certain drugs via three separate enzyme pathways (CYP2D6, CYP2C9, and CYP3A4 substrates)—though these remain Minor theoretical risks not yet seen in humans.
Bladderwrack and spirulina blue-green algae both carry Minor Moderate concerns with blood thinners (anticoagulants and antiplatelet drugs). Spirulina also poses a Moderate risk with diabetes medications (it may lower blood sugar) and immunosuppressants (it may boost immune activity, potentially interfering with the medication's intended effect).
We could not check nori, wakame, kombu, Atlantic kelp, aquamin mineralized seaweed, or phenalgin canary island algae extract—we hold no interaction data for these. Check your exact medications with the search tool on this page before starting this product.

For each ingredient in Marine Greens 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
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.
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.
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.
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.
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.
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.
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.
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.
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.
Spirulina Blue-Green Algae
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.
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.
Immunosuppressants
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Blue-green algae have been shown to stimulate the immune system.
Dulse
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.
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.
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.
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.
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.
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.
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.
