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 1200 mg is a single-ingredient supplement: chlorella powder, a freshwater green algae. The product also contains hydroxypropylmethylcellulose, an inactive ingredient used as a capsule material.

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 tracked in the data we hold—including brain tumor, fatty liver disease, depression, and fatigue—the evidence isn't established or is insufficient to rate it.

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, though product quality and purity vary widely. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, photosensitivity, and stool discoloration.

In clinical trials, digestive upset (especially nausea and diarrhea) was mild and occurred mainly in the first two weeks. Rare serious adverse effects include anaphylaxis.

The safety notes in our data advise against use unless your doctor approves it, because long-term safety hasn't been established.

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 starting Chlorella 1200 mg, double-check if you take warfarin (Coumadin) or any photosensitizing drugs. Warfarin users are at Moderate risk—chlorella's vitamin K can reduce its blood-thinning effect.

Photosensitizing medications face the same Moderate risk if you combine them with chlorella's own photosensitivity. Use the medication checker on this page to be sure.

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 have iron deficiency anemia, though evidence is preliminary. If you take warfarin or any drug that makes your skin photosensitive, talk to your pharmacist before you start.

Product purity varies—make sure you're getting a reliable brand. Check in with us on your full medication list.

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 1200 mg by Fresh Healthcare: Common Questions

Does Chlorella 1200 mg by Fresh Healthcare interact with any medications?
Yes. Based on its ingredients, Chlorella 1200 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?
Chlorella 1200 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 while breastfeeding?
The data we hold doesn't include safety information for lactation. Talk with your doctor or pharmacist before using it while breastfeeding.
Can I take this if I'm pregnant?
Chlorella is rated possibly safe in pregnancy. If you're interested in using it—especially for pregnancy-related iron deficiency—discuss it with your doctor first, since long-term safety hasn't been fully established.
What are the most common side effects?
Most people tolerate it well, but you might experience allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, or stool discoloration. Digestive side effects tend to show up in the first two weeks and are usually mild.
Will this help with fatigue?
The evidence isn't established in the data we hold. There's not enough reliable evidence yet to say whether chlorella works for fatigue.
Why does the label say to avoid chlorella unless my doctor approves it?
Long-term safety hasn't been established, and product purity and quality vary quite a bit between brands. Your doctor can help you decide if it's right for you and recommend a reliable source.
Can chlorella cause sun sensitivity?
Yes—chlorella has been reported to cause photosensitivity. In five case reports, people who took chlorella developed swelling and rash-like lesions on sun-exposed areas. If you're taking it, protect your skin from the sun or watch for any unusual reaction.
