HelloPharmacist Scorecard of Spirulina 410 mg by Solaray
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
Full disclosure
Solaray's Spirulina 410 mg contains 2 active ingredients: vitamin A and spirulina (a blue-green algae). The capsule also contains cellulose as an inactive ingredient.
Vitamin A is a fat-soluble vitamin your body uses for vision, immune function, and skin health. Spirulina is a nutrient-dense algae traditionally used as a dietary supplement.
Does it work?
Strong evidence
Vitamin A is established as effective for vitamin A deficiency and shows possibly effective evidence for oral leukoplakia, aging skin, measles, ulcerative colitis, and bronchopulmonary dysplasia (a lung condition in premature infants). Spirulina is possibly effective for high blood pressure; however, the evidence is insufficient to rate it for acne, hay fever, iron deficiency anemia, or arsenic poisoning.
How safe is it?
Well-documented data
Vitamin A is generally well tolerated at recommended amounts, but high doses build up in your body and can become toxic—causing liver damage, skin problems, hair loss, and in severe cases, brain swelling or coma. The safety data advises against high-dose vitamin A in pregnancy because it can cause birth defects; recommended dietary and supplement amounts are fine.
Spirulina appears well tolerated overall, though a small number of people report stomach upset (cramps, bloating, diarrhea, nausea), headache, dizziness, or fatigue. Rare allergic reactions, including anaphylaxis, have been reported.
A key concern: spirulina quality varies, and some products can be contaminated with toxins or heavy metals.
Meds to double-check
Major interaction found
Before taking this product, double-check with your pharmacist if you take retinoids (Major severity), blood thinners like warfarin, tetracycline antibiotics, other drugs that can stress the liver, diabetes medications, immunosuppressants, or antiplatelet drugs. High-dose vitamin A is the chief concern, and spirulina may amplify the effects of blood thinners or lower blood sugar.
The bottom line
Scorecard at a glanceFully disclosed formula with strong clinical evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.
If you're taking retinoid acne medications, blood thinners, tetracycline antibiotics, diabetes drugs, or immunosuppressants, you need to check this product with your pharmacist before starting. The vitamin A content is the main driver of risk at higher doses.
Spirulina's contamination risk is real—quality control matters. This isn't a supplement to take without verifying it's right for your specific situation.

Discussion: Spirulina is considered to be a nutritionally dense food due to high levels of nutrients including protein, vitamins, minerals, essential fatty acids and carotenoids such as beta carotene. Spirulina is also rich in chlorophyll, which gives Spirulina its rich green pigment.

Spirulina 410 mg by Solaray Drug Interactions
HelloPharmacist Interaction Report
Solaray's Spirulina 410 mg contains two active ingredients—vitamin A and spirulina—and interactions are documented for both.
Vitamin A is the source of the most serious concern: it can interact with retinoids (vitamin A derivatives) to cause supratherapeutic vitamin A levels and additive toxic effects, a Major-severity interaction. High-dose vitamin A also carries Moderate-severity risks with blood thinners like warfarin, tetracycline antibiotics (which can increase the risk of a specific type of brain swelling), and other drugs that stress the liver.
Read the full breakdown — every affected drug type, severity by severity
Spirulina brings three Moderate-severity interactions: it may theoretically increase bleeding risk with blood thinners or antiplatelet drugs; it can stimulate the immune system, potentially interfering with immunosuppressants; and it may lower blood sugar, raising the risk of hypoglycemia if you're on diabetes medications.
Altogether, these interactions span 644 individual medications. Because this product's vitamin A content matters for safety, check your exact medications with the search tool on this page before starting.

For each ingredient in Spirulina 410 mg 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.
Vitamin A
Retinoids
Concomitant use of retinoids with vitamin A supplements might produce supratherapeutic vitamin A levels.
Retinoids, which are vitamin A derivatives, could have additive toxic effects when taken with vitamin A supplements.
Hepatotoxic Drugs
Theoretically, taking high doses of vitamin A in combination with other potentially hepatotoxic drugs might increase the risk of liver disease.
The tolerable upper intake level (UL) is the highest level of intake that is likely to pose no risk of adverse effects. Doses of vitamin A above the UL can cause hepatotoxicity, ranging from elevated liver enzymes to liver failure.
Tetracycline Antibiotics
Theoretically, taking tetracycline antibiotics with high doses of vitamin A can increase the risk of pseudotumor cerebri.
Benign intracranial hypertension (pseudotumor cerebri) can occur with tetracyclines and with acute or chronic vitamin A toxicity. Case reports suggest that taking tetracyclines and vitamin A concurrently can increase the risk of this condition. Avoid high doses of vitamin A in people taking tetracyclines chronically.
Warfarin (Coumadin)
Theoretically, high doses of vitamin A could increase the risk of bleeding with warfarin.
Vitamin A toxicity is associated with hemorrhage and hypoprothrombinemia, possibly due to vitamin K antagonism. Advise patients taking warfarin to avoid doses of vitamin A above the tolerable upper intake level of 10,000 IU/day for adults.
Spirulina
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.
