HelloPharmacist Scorecard of Chlorella Powder by Sun Potion

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 12, 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.

Chlorella Powder contains one active ingredient: chlorella pyrenoidosa, a freshwater algae. The product has no 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).

The evidence for chlorella is mixed and limited. It's rated possibly effective for pregnancy-related iron deficiency.

For brain tumors, nonalcoholic fatty liver disease, depression, and fatigue, the evidence isn't established well enough to rate it — we simply don't have reliable data. If you're considering this for one of those conditions, talk with your doctor about what the science actually supports right now.

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 there's an important caveat: product quality and purity vary widely, and there isn't enough long-term safety data — avoid it unless your doctor approves. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, photosensitivity, and darkened stools, especially in the first two weeks.

A small number of trial participants reported nausea or diarrhea; in one trial, a few patients had worsening constipation or mild diarrhea. Serious reactions like anaphylaxis are rare but have been reported, including in people preparing chlorella tablets.

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 taking if you're on warfarin or other blood thinners (Coumadin) — chlorella is high in vitamin K and can make them less effective. Also check if you take any photosensitizing drugs (medications that make your skin sun-sensitive) — chlorella can add to that effect.

Check your own medication Run your meds through the checker above

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 pregnancy-related iron deficiency, but the evidence for other uses isn't solid. It's not a concern for most people taking it short term, though side effects like nausea, gas, and diarrhea can happen early on.

If you take warfarin or other blood thinners, or any medication that increases sun sensitivity, don't start this without checking with your pharmacist first. And because quality varies so much, talk with your doctor before using it.

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.

Chlorella Powder by Sun Potion: Common Questions

Does Chlorella Powder by Sun Potion interact with any medications?
Yes. Based on its ingredients, Chlorella Powder 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?
Chlorella Powder 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 it safe to take while pregnant?
The safety data rates chlorella as possibly safe in pregnancy, but there isn't enough information to be certain. Talk with your doctor or pharmacist about whether it's right for you personally — they can weigh the data against your specific situation.
What are the most common side effects?
Gas, nausea, constipation, diarrhea, and abdominal cramping are most common, especially in the first couple of weeks. A small number of people report fatigue, darkened stools, or allergic reactions. These usually settle down once your body adjusts.
Does it actually work for fatigue or depression?
The evidence isn't established yet — we don't have reliable data to say it works for either one. If that's why you're thinking about it, check with your doctor about treatments that do have solid evidence behind them.
Can it cause a serious allergic reaction?
Anaphylaxis has been reported, though it's rare. Allergic reactions including asthma have also been reported, including in people who were just preparing the tablets. If you've had allergies to algae or seaweed before, mention that to your pharmacist.
Why does the product quality vary so much?
The facts note that product quality and purity vary widely — that's all the data says. The bottom line is there isn't enough long-term safety data, so it's smart to run it by your doctor before starting.
