HelloPharmacist Scorecard of Ultra Blue Green Algae by Rexall
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
Ultra Blue Green Algae contains three active ingredients: spirulina, watercress, and a blue-green algae blend. The product also contains gelatin as an inactive ingredient (the capsule material).
Spirulina is a type of blue-green algae rich in protein and micronutrients. Watercress is a leafy green vegetable known for its nutrient density.
The blue-green algae blend serves as an additional source of these nutrient-rich algae.
Does it work?
Moderate evidence
For spirulina and the blue-green algae blend, there's evidence that they may be effective for high blood pressure (hypertension). For acne, allergic rhinitis (hay fever), iron deficiency anemia, and arsenic poisoning, the evidence is insufficient to rate how well they work.
The facts we hold don't include effectiveness ratings for watercress.
How safe is it?
Well-documented data
Spirulina is generally well tolerated orally, though some people report abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting. Allergic reactions can occur — in one case report, a young person experienced a severe reaction (anaphylaxis) with throat swelling and asthma.
A few people taking spirulina reported mild gum bleeding or bruising. Quality varies widely, and some products can be contaminated with toxins or heavy metals, which is a significant safety concern.
Watercress in food amounts is generally safe, but the product uses a concentrated form. Excessive doses may irritate the digestive tract.
Raw, wild watercress can carry parasitic flukes that cause a liver disease (fascioliasis) with abdominal pain, fever, vomiting, and diarrhea. There's limited safety data for watercress as a medicinal supplement.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist if you take blood thinners or antiplatelet drugs, drugs that suppress your immune system, diabetes medications, lithium, warfarin, or chlorzoxazone (a muscle relaxant). All carry Moderate interactions with these ingredients.
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 product may help with high blood pressure, though evidence for other uses is unclear. If you take blood thinners, diabetes medication, immunosuppressants, lithium, muscle relaxants, or any other medication, check this product against your specific drugs before starting.
Quality and contamination are real concerns with algae supplements — talk to your pharmacist about whether this brand is right for you.

Ultra Blue Green Algae by Rexall Drug Interactions
HelloPharmacist Interaction Report
Ultra Blue Green Algae by Rexall contains spirulina and watercress, both of which interact with medications.
Spirulina carries Moderate interactions with blood thinners and antiplatelet drugs — it may theoretically increase bleeding risk, though this is unlikely based on available evidence.
Read the full breakdown — every affected drug type, severity by severity
Spirulina also has Moderate interactions with drugs that suppress the immune system (immunosuppressants), since spirulina stimulates immune activity and may interfere with their intended effect. Additionally, spirulina may lower blood sugar (hypoglycemia) when taken with diabetes medications; human research shows spirulina can reduce blood sugar in diabetic patients, though it doesn't appear to improve long-term blood sugar control (HbA1c).
Watercress adds three more Moderate interactions: it may raise lithium levels due to diuretic effects; it can increase the concentration and effects of chlorzoxazone, a muscle relaxant; and because watercress contains vitamin K, large amounts might reduce how well warfarin (a blood thinner) works. Altogether, these interactions span 326 individual medications.

Blue Green Algae Blend
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.
