HelloPharmacist Scorecard of Mega Greens 600 mg by Wonder Laboratories
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
Mega Greens 600 mg contains three active ingredients: chlorella, klamath blue-green algae, and spirulina. These are nutrient-dense whole-food algae sources often used as nutritional supplements to supply vitamins, minerals, and plant compounds.
The product also contains gelatin and vegetable magnesium stearate as inactive ingredients (capsule material and flow agent).
Does it work?
Moderate evidence
The evidence for these ingredients is mixed. Chlorella is possibly effective for pregnancy-related iron deficiency.
Spirulina and klamath blue-green algae are possibly effective for high blood pressure, but for most other uses in this product—acne, allergies, anemia, and arsenic exposure—the evidence is insufficient to make a reliable claim. Depression, fatigue, and liver disease have not been established in the data we hold for these ingredients.
How safe is it?
Well-documented data
All three algae are generally well tolerated in the short term, but there are important caveats. Product quality and purity vary widely, and contamination with toxins or heavy metals is a documented concern—one reason the safety data advises caution or avoidance unless your doctor approves.
Common side effects include abdominal cramping, bloating, diarrhea, nausea, fatigue, and headache, especially during the first two weeks. Allergic reactions including asthma and anaphylaxis are rare but have been reported.
Chlorella can also cause photosensitivity (abnormal sun sensitivity) and may discolor your stool. For pregnancy and lactation, chlorella is rated possibly safe in pregnancy, but safety data is not on file for klamath blue-green algae or spirulina during pregnancy or breastfeeding.
Talk with your doctor or pharmacist before taking this product if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before taking Mega Greens, double-check with your doctor or pharmacist if you take blood thinners like warfarin—chlorella's vitamin K content can make them less effective, and the blue-green algae ingredients may add to bleeding risk. Also flag diabetes medications (risk of low blood sugar), immune-suppressing drugs (algae may counteract them), and any medications that increase sun sensitivity.
If you're on any of these, confirm this product won't interfere.
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.
Mega Greens 600 mg is not a simple add-on if you take blood thinners, diabetes medications, immune-suppressing drugs, or photosensitizing medications. The algae quality in supplements varies, and contamination risk is real.
If you're interested in this product, check your specific medications with the tool on this page and discuss it with your doctor or pharmacist—they know your full health picture and can tell you whether it's safe for you.

Mega Greens 600 mg by Wonder Laboratories Drug Interactions
HelloPharmacist Interaction Report
Mega Greens 600 mg by Wonder Laboratories does interact with several medication types through its chlorella, klamath blue-green algae, and spirulina content.
The most serious documented concern is moderate-severity interaction with blood thinners like warfarin (Coumadin): chlorella contains significant vitamin K, which can reduce how well warfarin works and make your clotting protection less effective.
Read the full breakdown — every affected drug type, severity by severity
The blue-green algae ingredients (klamath and spirulina) carry moderate-severity interactions with blood thinners and antiplatelet drugs as well—they've shown blood-thinning effects in lab studies, though human evidence of bleeding risk remains limited. Additionally, both blue-green algae may theoretically interfere with immune-suppressing medications (like those used after transplant or for autoimmune conditions) because they stimulate immune function.
They can also theoretically increase the risk of low blood sugar (hypoglycemia) if you're taking diabetes medications, since spirulina itself has been shown to lower blood sugar in some patients.
Chlorella can also cause photosensitization—increased sensitivity to sunlight—and theoretically adds to that risk if you're already taking photosensitizing drugs. Altogether, these interactions span 626 individual medications.
Use the search tool below to check your exact medications before starting this product, and talk with your doctor or pharmacist about whether it's right for you.

For each ingredient in Mega Greens 600 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.
Chlorella
Photosensitizing Drugs
Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.
Warfarin (Coumadin)
Theoretically, chlorella might reduce the clinical effects of warfarin.
Chlorella contains significant amounts of vitamin K. There is at least one case report of warfarin therapy becoming sub-therapeutic after initiation of chlorella supplements.
Klamath 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.
