HelloPharmacist Scorecard of Organic Chlorella + Spirulina by Herbadiet

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

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.

This product contains 2 active ingredients: broken cell wall chlorella and blue-green algae spirulina. Both are nutrient-dense algae — chlorella is a freshwater green alga, while spirulina is a blue-green alga.

The product uses a vegetable cellulose capsule shell as its only inactive ingredient.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: nutrient support, energy, cognitive function, immunity.
  • We looked for evidence on: Cognitive Impairment, Memory, Mental alertness, Fatigue, Iron deficiency anemia, Malnutrition — and 2 related terms.
  • The closest evidence on file: Chlorella is rated "Insufficient Reliable Evidence To Rate" for Fatigue (Natural Medicines).
  • Also on file: Blue-green Algae is rated "Insufficient Reliable Evidence To Rate" for Iron deficiency anemia, Cognitive Impairment, Memory, Mental alertness, and more.

For chlorella, the evidence is mixed. It's possibly effective for pregnancy-related iron deficiency, but the data on brain tumors, fatty liver disease, depression, and fatigue is insufficient to rate.

For spirulina, it's possibly effective for high blood pressure, but evidence is insufficient for acne, hay fever, iron deficiency anemia, and arsenic poisoning. In both cases, more research is needed to confirm how well they work for most of these uses.

The evidence, ingredient by ingredient Chlorella 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both ingredients are generally well tolerated short term, but here's the catch: product quality and purity vary widely, and some batches can be contaminated with toxins or heavy metals — that's a real concern with algae products. Common side effects include stomach cramping, nausea, diarrhea, fatigue, bloating, and headache, especially in the first two weeks.

Rare but serious reactions like anaphylaxis and asthma have been reported. For chlorella specifically, photosensitivity (sun-related skin reactions) and green stool discoloration can occur.

For spirulina, mild gum bleeding and bruising have been documented in a few cases. Chlorella is rated possibly safe in pregnancy, but there isn't enough safety data for spirulina in pregnancy or lactation — talk with your doctor or pharmacist before using either during these times.

Side effects, ingredient by ingredient Chlorella Blue-green Algae

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?
  • 2 of the 2 matched ingredients can interact with medications — Chlorella, 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: 626 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 before you start if you take blood thinners like warfarin, since chlorella's vitamin K content can make them less effective. Also flag diabetes medications, immune-suppressing drugs, antiplatelet drugs, and any medications that increase sun sensitivity.

Your doctor or pharmacist can review your specific list and let you know if it's safe to add this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This dual-algae product may help with high blood pressure or pregnancy-related iron deficiency, but the evidence is thin for other uses. The bigger issue is that if you take blood thinners, diabetes medications, or immune-suppressing drugs, you'll need to clear this with your doctor or pharmacist first because of real interaction risks.

Even without those concerns, algae products vary in quality and purity, so sourcing matters.

broken cell wall Chlorella2 drug types · 337 drugs

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.

Likelihood Possible Evidence D
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.

Likelihood Possible Evidence D

Blue-Green Algae Spirulina3 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.

Organic Chlorella + Spirulina by Herbadiet: Common Questions

Does Organic Chlorella + Spirulina by Herbadiet interact with any medications?
Yes. Based on its ingredients, Organic Chlorella + Spirulina has a known interaction with 626 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Chlorella + 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.
Can I take this if I'm on warfarin or another blood thinner?
Not without checking first. Chlorella in this product contains a lot of vitamin K, which can interfere with blood thinners like warfarin and make them less effective — there's even a case report of this happening. Talk with your doctor or pharmacist before starting, since they can monitor you or adjust your dose if needed.
What are the most common side effects?
Stomach cramping, nausea, diarrhea, bloating, and fatigue — especially during the first two weeks. A small number of people have also reported photosensitivity (sun-related skin reactions with chlorella) and mild gum bleeding or bruising with spirulina. Most side effects are temporary.
Is this safe during pregnancy or while breastfeeding?
Chlorella is rated possibly safe in pregnancy, but there isn't enough safety data on spirulina for either pregnancy or lactation. Talk with your doctor or pharmacist for personalized advice before taking this product during these times.
Will this help with my fatigue or depression?
The evidence isn't there yet. While chlorella and spirulina are nutrient-dense, the data we hold doesn't support either ingredient for fatigue or depression — that's why both are rated insufficient evidence to rate for those uses.
How much vitamin K is actually in this product?
The product facts don't specify the exact amount of vitamin K per dose, only that chlorella contains significant amounts. If blood thinners are a concern, ask your pharmacist to help you find out the exact vitamin K content so your doctor can advise you.
Should I worry about contamination?
Yes — both chlorella and spirulina can be contaminated with toxins or heavy metals, and product quality varies widely. Buy from a trusted source and consider asking your pharmacist or the manufacturer about their testing and purity standards.
