HelloPharmacist Scorecard of Perfect Chlorella 2400 mg by Perfect Supplements

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Perfect Chlorella 2400 mg contains one active ingredient: chlorella, a freshwater algae. The capsule itself is made from pullulan, an inactive ingredient.

Chlorella is a single-celled green alga that's been studied for a range of uses, from pregnancy-related iron deficiency to liver and brain health. The 2400 mg dose in each capsule delivers the whole algae in concentrated form.

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: digestion and immune support.
  • We looked for evidence on: Exercise-induced respiratory infections, Ulcerative colitis, Gut health, Immune function, Inflammatory bowel disease.
  • The closest evidence on file: Chlorella is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced respiratory infections (Natural Medicines).
  • Also on file: Chlorella is rated "Insufficient Reliable Evidence To Rate" for Ulcerative colitis.

The evidence for chlorella is mixed and incomplete. It's rated possibly effective for pregnancy-related iron deficiency — the strongest claim we have.

For brain tumors, nonalcoholic fatty liver disease, depression, and fatigue, the evidence isn't established well enough in the data we hold to say whether it works. If you're considering this supplement for one of those other uses, talk with your pharmacist or doctor about what the current research actually supports.

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 over the short term, but product quality and purity vary widely from brand to brand — that's something to keep in mind. The most common side effects are allergic reactions (including asthma), abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, photosensitivity, and green-tinted stool, especially in the first two weeks.

A rare but serious side effect is anaphylaxis (a severe allergic reaction). We don't have enough safety data to recommend chlorella unless your doctor has approved it for you.

There's no established safety data for pregnancy or breastfeeding — talk with your doctor or pharmacist before using this if you're pregnant or nursing.

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 your pharmacist if you take warfarin or any blood thinner — chlorella's vitamin K content can reduce how well these drugs work. Also double-check any photosensitizing medications (drugs that increase sun sensitivity) before adding this product.

If you're not sure whether your medications fall into these categories, the search tool on this page can help.

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 may be worth considering if your doctor recommends it for pregnancy-related iron deficiency and you've ruled out any interactions. Be cautious if you take warfarin or a photosensitizing medication — both need a conversation with your pharmacist first.

Quality varies, so if you do use it, stick with a reputable brand.

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.

Perfect Chlorella 2400 mg by Perfect Supplements: Common Questions

Does Perfect Chlorella 2400 mg by Perfect Supplements interact with any medications?
Yes. Based on its ingredients, Perfect Chlorella 2400 mg 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?
Perfect Chlorella 2400 mg 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?
There isn't enough safety data to say. Talk with your doctor or pharmacist before using chlorella if you're pregnant or planning to become pregnant — they can weigh the pros and cons for your situation.
What are the side effects?
The most common ones are allergic reactions, stomach cramping, constipation, diarrhea, fatigue, gas, and nausea — especially in the first two weeks. Your stool might turn green, too. Rarely, some people have had severe allergic reactions like anaphylaxis.
Does chlorella actually work for what it claims?
The evidence is strongest for pregnancy-related iron deficiency — that's rated possibly effective. For brain health, liver health, depression, or fatigue, we don't have enough reliable evidence to say it works. Your doctor can tell you whether it makes sense for your specific situation.
Why does the product quality matter?
Chlorella purity and quality vary significantly from brand to brand. That's why it matters where you source it — a reputable manufacturer is important if you decide to use it.
What is chlorella, exactly?
It's a single-celled green freshwater algae that's been studied for various health uses. This product gives you 2400 mg of the whole algae per capsule.
Can chlorella make me more sensitive to the sun?
Yes — chlorella has been reported to cause photosensitization in some people, resulting in swelling and red or purple lesions on sun-exposed skin. That risk might increase if you also take a medication that makes your skin sun-sensitive.
