HelloPharmacist Scorecard of Cracked Cell Chlorella by Purium

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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.

Cracked Cell Chlorella contains one active ingredient: chlorella, a freshwater algae. It's a whole-food supplement, meaning you're getting the algae itself rather than an isolated compound.

The product has no inactive fillers or binders listed.

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 — see Chlorella's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: cellular cleanse and detoxification support.
  • We looked for evidence on: Nonalcoholic fatty liver disease (NAFLD), Hepatitis C, Hyperlipidemia, Metabolic syndrome, heavy metal detoxification, general detoxification — and 1 related terms.
  • The closest evidence on file: Chlorella is rated "Insufficient Reliable Evidence To Rate" for Nonalcoholic fatty liver disease (NAFLD) (Natural Medicines).
  • Also on file: Chlorella is rated "Insufficient Reliable Evidence To Rate" for Hepatitis C, Hyperlipidemia, Metabolic syndrome.

The evidence for chlorella is mixed. It's possibly effective for pregnancy-related iron deficiency, but that's the strongest claim we have.

For brain tumors, fatty liver disease, depression, and fatigue, the evidence we hold is insufficient to rate whether it works or not. If you're considering this for any of those uses, talk with your doctor about what the current research shows.

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 when taken short-term, but quality and purity vary widely between products, so choose carefully. The most common side effects are allergic reactions, stomach cramping, constipation, diarrhea, fatigue, gas, nausea, and photosensitivity (sun sensitivity)—especially in the first two weeks.

Rare but serious allergic reactions, including anaphylaxis, have been reported. There isn't enough safety data to know how safe this product is during pregnancy or breastfeeding, so talk with your doctor or pharmacist before using it if you're pregnant, planning to become pregnant, or breastfeeding.

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.

Check with us before taking this if you're on warfarin or another blood thinner (Moderate severity)—chlorella's vitamin K content can reduce how well they work. Also double-check if you take photosensitizing drugs that make your skin more sun-sensitive (Moderate severity).

Use the search tool on this page with your exact medication names.

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.

Chlorella might help with pregnancy-related iron deficiency, but the evidence for other uses is unclear. The main thing to watch is whether you take blood thinners or photosensitizing medications—both can be affected.

Talk with your pharmacist before starting, especially if you take warfarin or any prescription drugs.

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.

Cracked Cell Chlorella by Purium: Common Questions

Does Cracked Cell Chlorella by Purium interact with any medications?
Yes. Based on its ingredients, Cracked Cell 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?
Cracked Cell 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.
What's in Cracked Cell Chlorella?
It's just one ingredient: chlorella, a freshwater algae, with no added fillers or binders. The "cracked cell" refers to how the algae's cell wall is processed to make it easier for your body to absorb.
Will it give me more energy?
Energy and fatigue are listed uses, but we don't have enough reliable evidence to say whether chlorella actually works for that. If you try it and feel better, that's great—but don't count on it based on the research we hold.
Can I take this if I'm pregnant?
There isn't enough safety data to know either way. Talk with your doctor or pharmacist for personalized advice before using it during pregnancy or breastfeeding.
What side effects might I get?
The most common ones are stomach cramping, diarrhea, constipation, nausea, gas, fatigue, and—importantly—photosensitivity, which means your skin becomes more sensitive to sunburn. Allergic reactions, including serious ones, have been reported too. These are usually mild, especially in the first two weeks.
Why does quality vary?
Chlorella products differ in purity and what contaminants they may contain. That's why we recommend checking the manufacturer's third-party testing or quality certifications before you buy.
Will this interfere with my warfarin?
Chlorella is high in vitamin K, which works against warfarin. There's a case report of someone's warfarin therapy becoming ineffective after starting chlorella. If you take warfarin or any blood thinner, do not start this without checking with your pharmacist first.
