HelloPharmacist Scorecard of All Natural Blue Green Micro Algae by OL Olympian Labs Incorporated

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 Jul 16, 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 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: blue-green algae (spirulina). It comes in a capsule with inactive ingredients — rice flour, microcrystalline cellulose (a binder), ascorbyl palmitate (a form of vitamin C used as a preservative), and silica.

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).

The data shows blue-green algae is possibly effective for high blood pressure (hypertension). For acne, hay fever (allergic rhinitis), iron deficiency anemia, and arsenic poisoning, the evidence is insufficient to know whether it works — we don't have enough reliable data 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.

Blue-green algae is generally well tolerated when taken by mouth. The most common side effects reported are abdominal cramps, bloating, diarrhea, dizziness, fatigue, gas, headache, nausea, and vomiting — usually mild and temporary.

Allergic reactions are rare but possible, including skin rashes, itching, and in one reported case, a serious reaction (anaphylaxis) in a teenager. A few people taking spirulina have reported mild gum bleeding or bruising.

One important safety note: quality and contamination vary widely among blue-green algae products. Some have been found to contain toxins or heavy metals — a real concern that makes caution important.

The data on safety in pregnancy and breastfeeding is not on file, so talk with your doctor or pharmacist before taking this if you're pregnant, planning to become pregnant, or nursing.

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 — Blue-green Algae.
  • The most serious interaction on file is rated Moderate.
  • 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.

Check with your doctor or pharmacist before taking this product if you use blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel), immunosuppressants, or antidiabetes medications — blue-green algae has moderate-severity interactions with all three categories. Your doctor or pharmacist can help you decide whether it's safe for your specific situation.

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.

Blue-green algae may help with high blood pressure, but the evidence for other uses isn't established. If you take blood thinners, immune-suppressing drugs, or diabetes medications, you need to check with your doctor or pharmacist before adding this — the interactions are real even if uncommon in practice.

Quality varies, so contamination is a legitimate concern; discuss this product and a trustworthy brand with your pharmacist.

Blue Green Micro 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.

How can one product interact with so many drugs?
All Natural Blue Green Micro Algae 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.
Does blue-green algae actually work for high blood pressure?
The data shows it's possibly effective for high blood pressure, meaning there's some evidence it may help — but it's not proven. Talk with your doctor before relying on it as a treatment, and don't stop any blood pressure medication without their say-so.
What are the most common side effects?
Stomach cramps, bloating, diarrhea, dizziness, tiredness, gas, headache, nausea, and vomiting are the most frequently reported — usually mild. Allergic reactions like rashes or itching are rare but can happen, and in very rare cases a serious allergic reaction is possible.
Is this safe during pregnancy or breastfeeding?

What's the contamination concern I hear about blue-green algae?
Some blue-green algae products have been found to contain toxins or heavy metals. Quality varies widely between brands and batches, so it's worth discussing a reputable source with your pharmacist.
Can I take this if I'm on blood thinner medication?
Not without checking with your doctor first — there's a documented moderate-severity interaction. Blue-green algae may increase bleeding risk when combined with blood thinners, even though serious problems are unlikely. Your doctor or pharmacist can help you decide if it's safe for you.
