HelloPharmacist Scorecard of Sea Moss with Spirulina by Atlantic Naturals

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 Sep 10, 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Sea Moss with Spirulina contains two active ingredients: certified organic spirulina powder and organic Irish Moss. Spirulina is a type of blue-green algae rich in protein and nutrients; Irish Moss is a seaweed used traditionally for its mineral content.

The capsules themselves are made from methylcellulose and microcrystalline cellulose, which are inactive ingredients that form the capsule shell and help with absorption.

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 Blue-green Algae's overall clinical evidence instead.

Moderate

Some clinical evidence supports Blue-green Algae 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 ingredient's overall clinical evidence instead.
  • On file: Hypertension — rated "Possibly Effective" (Natural Medicines).

For spirulina, the evidence shows it is possibly effective for high blood pressure (hypertension). For acne, allergic rhinitis (hay fever), iron deficiency anemia, and arsenic poisoning, the evidence we hold is insufficient to rate whether spirulina works.

We don't have effectiveness data for Irish Moss on file.

The evidence, ingredient by ingredient Blue-green Algae

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.

Spirulina is generally well tolerated when taken by mouth. The most common side effects reported are abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting.

Allergic reactions are rare but can occur — a small number of case reports describe urticarial rashes, itching, and in one case a severe allergic reaction (anaphylaxis) in a teenager. Mild gum bleeding and bruising have been reported in a few people taking spirulina.

A major safety concern is that the quality of spirulina products varies widely and some can be contaminated with toxins or heavy metals — this is an important reason to buy from a trusted source. We have no pregnancy or breastfeeding safety data on file for either ingredient.

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 — Blue-green Algae.

  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 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, check with your doctor or pharmacist if you use anticoagulant or antiplatelet drugs (blood thinners and anti-clotting medications, Moderate severity), immunosuppressants (Moderate severity), or antidiabetes drugs (Moderate severity). No interactions are documented in our data for the Irish Moss ingredient.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you're interested in a spirulina-based supplement and your blood pressure is elevated, though evidence for other uses is not yet established. If you take blood thinners, immunosuppressants, or diabetes medications, check your exact drugs with your doctor or pharmacist before starting.

Talk it over with your healthcare provider to see if it's right for you.

certified organic Spirulina powder3 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.

Sea Moss with Spirulina by Atlantic Naturals: Common Questions

Does Sea Moss with Spirulina by Atlantic Naturals interact with any medications?
Yes. Based on its ingredients, Sea Moss with Spirulina has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Sea Moss with Spirulina contains 2 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 spirulina actually lower blood pressure?
The evidence suggests spirulina is possibly effective for high blood pressure, meaning there's some promising research. However, it's not proven enough to be called a standard treatment — talk with your doctor about whether it might be useful alongside your other care.
Can I take this if I'm allergic to seafood or iodine?
Both spirulina and Irish Moss are algae from the ocean, so if you have a seafood allergy or iodine sensitivity, there's a real risk of a reaction. Allergic responses to spirulina have been documented. Check with your doctor or pharmacist before trying it.
What are the most common side effects?
The most frequent side effects are digestive: abdominal cramps, bloating, diarrhea, flatulence, and nausea. Dizziness, fatigue, and headache have also been reported. Most people tolerate spirulina well, but start with a low dose to see how your body responds.
Is this product safe from contamination?
Quality and safety vary widely among spirulina products — some can contain toxins or heavy metals. Buy from a reputable source and look for third-party testing when available to lower that risk.
Can I take this while pregnant or breastfeeding?
We don't have safety data on file for either spirulina or Irish Moss during pregnancy or breastfeeding. Talk with your doctor or pharmacist before taking it if you're pregnant, planning to become pregnant, or breastfeeding.
Will this help with acne or anemia?
The evidence we hold is insufficient to say whether spirulina works for acne or iron deficiency anemia. While it's popular for these uses, the science hasn't established it yet.
