HelloPharmacist Scorecard of Organic Chlorella 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.

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.

Herbadiet's Organic Chlorella is a single-ingredient supplement: chlorella, a freshwater green algae, in a vegetable cellulose capsule. Chlorella is nutrient-dense and has been studied for a range of purposes, though the quality and purity of chlorella products can vary widely from one brand to another.

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 Chlorella's overall clinical evidence instead.

Moderate

Some clinical evidence supports Chlorella for:

Why this rating?
  • The label markets general wellness (“supports detoxification and digestive health”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Pregnancy-related iron deficiency — rated "Possibly Effective" (Natural Medicines).

Chlorella is possibly effective for pregnancy-related iron deficiency. For other uses listed — brain tumor, nonalcoholic fatty liver disease (NAFLD), depression, and fatigue — the evidence is insufficient to rate whether it works.

If you're considering it for iron support in pregnancy, talk with your doctor or midwife first to make sure it fits your care plan.

The evidence, ingredient by ingredient Chlorella

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.

Chlorella is generally well tolerated in the short term, but long-term safety hasn't been firmly established — the manufacturer advises against using it unless your doctor approves. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, skin sensitivity to sun (photosensitivity), and greenish stool discoloration.

Most digestive upset happens in the first two weeks. Rarely, anaphylaxis (a severe allergic reaction) has been reported.

Because product quality varies, purity issues may also play a role in how you tolerate it.

Side effects, ingredient by ingredient Chlorella

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 — Chlorella.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 337 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.

Before you start, double-check with your doctor or pharmacist if you take warfarin (Coumadin) or any photosensitizing medications (drugs that increase your skin's sensitivity to sunlight). Warfarin's effectiveness may be reduced by chlorella's vitamin K content, and chlorella might add to photosensitivity risk from other drugs.

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.

Herbadiet's Organic Chlorella may be worth considering if you have pregnancy-related iron deficiency and your doctor agrees, or if you're exploring it for another reason under medical guidance. Steer clear or get specific clearance if you take warfarin or photosensitizing drugs.

Start by talking with your doctor or pharmacist — they can review your full health picture and confirm it's right for you.

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.

Organic Chlorella by Herbadiet: Common Questions

Does Organic Chlorella by Herbadiet interact with any medications?
Yes. Based on its ingredients, Organic Chlorella has a known interaction with 337 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Chlorella 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.
Can I take this if I'm pregnant?
Chlorella is rated possibly safe in pregnancy, but safety data is limited. Talk with your doctor or midwife before starting — they'll know your specific situation and can advise whether it's right for you.
Will this help my energy?
Chlorella is studied for fatigue, but the evidence isn't strong enough yet to say whether it works. If low energy is a problem, your doctor can help figure out what's causing it and what might actually help.
What are the most common side effects?
Most people tolerate it okay, but you might notice digestive upset — abdominal cramping, diarrhea, gas, or nausea — especially in the first couple of weeks. Allergic reactions, skin sensitivity to sun, and stool discoloration can also happen. Rare cases of serious allergic reaction have been reported.
Is there anything in the capsule besides chlorella?
The capsule itself is made of vegetable cellulose. There are no other active ingredients — just the chlorella and the capsule material.
Why does the safety label say to avoid it unless my doctor approves?
Long-term safety data is limited, and chlorella product quality varies a lot from brand to brand. Your doctor can decide whether the benefits outweigh any risks for your situation.
Does chlorella have vitamin K in it?
Yes — chlorella contains significant amounts of vitamin K. That's why it can interfere with warfarin and other blood thinners. If you take those drugs, this is important to discuss with your pharmacist.
