HelloPharmacist Scorecard of Extra Strength Chlorella 500 mg by eXplicit 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 30, 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.

This product contains one active ingredient: chlorella, a single-celled green algae, at 500 mg per capsule. The capsule itself is made with cellulose, an inactive filler.

Chlorella is a whole-food algae supplement — you're getting the plant itself, not an extract of one component.

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?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • 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).

The data we hold shows chlorella is possibly effective for pregnancy-related iron deficiency. For brain tumor, nonalcoholic fatty liver disease (NAFLD), depression, and fatigue, the evidence isn't yet established in our data — there's insufficient reliable evidence to know if it works for these uses.

If you're considering chlorella for one of those latter conditions, talk with your doctor about what the current research actually shows and whether it makes sense for you.

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 short term, but product quality and purity vary widely — that's something to keep in mind when choosing a brand. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, photosensitivity, and stool discoloration.

Most of these tend to happen in the first two weeks. Serious allergic reactions, including anaphylaxis, are rare but have been reported.

Long-term safety hasn't been established, so avoid taking it unless your doctor approves. If you're pregnant, chlorella is possibly safe, but if you're breastfeeding, there isn't enough data — talk with your doctor or pharmacist about what's right for you.

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 taking this product, confirm with your doctor or pharmacist if you're on warfarin or any photosensitizing drug. Warfarin (a common blood thinner) can become less effective, and photosensitizing medications may have stronger sun-sensitivity effects when combined with chlorella.

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.

Chlorella may help with iron deficiency in pregnancy, but it can thin out warfarin's effect and may worsen photosensitivity. If you take warfarin or photosensitizing medications, or if you have any sun sensitivity, this product needs approval from your doctor or pharmacist first.

Check your exact medications with the tool on this page, and always talk with your healthcare provider before you start.

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.

Extra Strength Chlorella 500 mg by eXplicit Supplements: Common Questions

Does Extra Strength Chlorella 500 mg by eXplicit Supplements interact with any medications?
Yes. Based on its ingredients, Extra Strength Chlorella 500 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?
Extra Strength Chlorella 500 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.
Is chlorella safe to take long-term?
Safety for long-term use hasn't been established in the data we hold. It's generally well tolerated short term, but talk with your doctor before taking it ongoing.
Can I take chlorella if I'm pregnant?
Chlorella is rated possibly safe in pregnancy. That said, if you're thinking about taking it for any reason during pregnancy, check with your doctor or pharmacist first — they know your full situation.
What side effects might I notice?
The most common ones are stomach cramping, diarrhea, gas, nausea, and constipation, especially in the first two weeks. A small number of people have had allergic reactions, including severe ones. If you notice swelling or trouble breathing, stop and get emergency help right away.
Does chlorella actually work?
Chlorella is possibly effective for iron deficiency during pregnancy. For other common reasons people take it — depression, fatigue, liver health, or brain tumors — there isn't enough established evidence yet.
Why do I need to be careful about sun exposure with this product?
Chlorella can cause photosensitivity, meaning your skin becomes more sensitive to the sun. Case reports show people developed swelling and lesions on sun-exposed skin. If you're already on a photosensitizing medication, the effect could be stronger.
What does product quality have to do with safety?
Chlorella quality and purity vary widely between brands and batches. That variation can affect both what you get and how safe it is, so choose a reputable source.
