HelloPharmacist Scorecard of Clean Chlorella 200 mg Tablets by Health Ranger Select

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.

This product contains one active ingredient: chlorella, a freshwater algae. Chlorella is a concentrated source of nutrients including vitamin K, which is why it can interact with blood thinners.

The product has no other inactive ingredients listed.

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).

Chlorella is possibly effective for pregnancy-related iron deficiency. For other uses — brain tumors, fatty liver disease, depression, and fatigue — the evidence in our data is insufficient to rate whether it works.

If you're considering chlorella for any of these reasons, talk with your doctor about what the current research actually shows for your situation.

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 product quality and purity vary widely between brands, so sourcing matters. The most common side effects are mild: nausea, diarrhea, constipation, abdominal cramping, gas, fatigue, and skin sensitivity to sunlight.

These often ease up after the first couple of weeks. Rarely, serious allergic reactions including anaphylaxis have been reported, both in people taking it and in those handling chlorella powder during preparation.

Safety data for long-term use is limited. There isn't enough information on file about chlorella in pregnancy or breastfeeding — you'll want to talk with your doctor or pharmacist for personalized advice if you're considering it during either time.

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 before using if you take warfarin or other blood thinners — chlorella's vitamin K content can reduce their effectiveness. Also double-check if you're on photosensitizing medications, which work on your skin's light sensitivity.

Chlorella can add to that effect.

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 be worth considering if you're pregnant and dealing with iron deficiency and your doctor approves. Be cautious if you take blood thinners or photosensitizing medications — check with us or your pharmacist first.

Quality varies widely between brands, so that's worth keeping in mind. Talk to your pharmacist before starting, especially if you're on any prescription medication.

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.

Clean Chlorella 200 mg Tablets by Health Ranger Select: Common Questions

Does Clean Chlorella 200 mg Tablets by Health Ranger Select interact with any medications?
Yes. Based on its ingredients, Clean Chlorella 200 mg Tablets 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?
Clean Chlorella 200 mg Tablets 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 chlorella if I'm pregnant?
There isn't enough safety data on file about chlorella in pregnancy to say either way. Talk with your doctor or pharmacist about whether it's right for you — they know your full picture and can give you personalized advice.
Will chlorella actually work for fatigue?
The evidence in our data is insufficient to say whether chlorella works for fatigue. If that's why you're thinking about it, ask your doctor or pharmacist what the research actually supports.
What are the most common side effects?
Most people tolerate it fine, but the most common side effects are nausea, diarrhea, constipation, gas, and abdominal cramping — especially in the first two weeks. Some people also report fatigue or skin sensitivity to sun. These usually settle down quickly.
Does this product have any fillers or other inactive ingredients?
No inactive ingredients are listed for this product — it's just chlorella in the tablet.
Why does chlorella interact with blood thinners?
Chlorella is high in vitamin K, which tells your body to clot more. If you're on warfarin or another blood thinner, extra vitamin K can work against the medication and make it less effective at preventing clots.
