HelloPharmacist Scorecard of Yaeyama Chlorella by Healthy Origins

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: Yaeyama Chlorella, a type of freshwater algae. Chlorella is a whole-food supplement — no other active components are listed.

There are no inactive ingredients (fillers or binders) in this formulation.

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 we hold shows chlorella is possibly effective for pregnancy-related iron deficiency. For brain tumors, nonalcoholic fatty liver disease, depression, and fatigue, the evidence isn't established well enough for us to rate it either way.

If you're considering this for any of those other uses, talk with your doctor about what the current research 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 in the short term, though product quality and purity vary widely between manufacturers — that matters for safety. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, photosensitivity (sun sensitivity), and darkened stools, especially during the first two weeks.

Rare but serious reactions like anaphylaxis (severe allergic reaction) have been reported. There isn't enough safety data on chlorella for us to know how safe it is overall, so avoid it unless your doctor approves it for your situation.

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.

Double-check this product if you take warfarin (Coumadin) or any blood thinners — chlorella can make them less effective. Also check if you're on photosensitizing drugs (medications that increase sun sensitivity), as chlorella may 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.

Yaeyama Chlorella might help with pregnancy-related iron deficiency, but it's not established for other uses. If you take warfarin or photosensitizing drugs, you need to check with your pharmacist before starting.

Watch for digestive upset and sun sensitivity, especially in your first two weeks. Talk to your pharmacist about whether this product is right for you and your medications.

Yaeyama Chlorella2 drug types · 337 drugs

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.

Yaeyama Chlorella by Healthy Origins: Common Questions

Does Yaeyama Chlorella by Healthy Origins interact with any medications?
Yes. Based on its ingredients, Yaeyama Chlorella 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?
Yaeyama Chlorella 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 Yaeyama Chlorella safe during pregnancy?
There isn't enough safety data on file for us to know either way. If you're pregnant or thinking about taking this, talk with your doctor or pharmacist for personalized advice on whether it's right for you.
What are the most common side effects?
Most people tolerate it okay, but especially in the first two weeks you might notice digestive issues like gas, cramping, diarrhea, or nausea. Allergic reactions and sun sensitivity (photosensitivity) can also happen. If you're sensitive to sun exposure, be careful.
Can it help with fatigue or depression?
We don't have enough reliable evidence to say whether chlorella works for fatigue or depression. Talk with your doctor if you're thinking about it for either of those.
Why does product quality matter?
Chlorella products vary widely in quality and purity. That difference can affect both how well it works and how safe it is, so buying from a trusted manufacturer matters.
Can I take this if I'm on blood thinners?
Not without checking with your pharmacist first. Chlorella is high in vitamin K, which can make warfarin and other blood thinners less effective. Your pharmacist needs to know your exact medication before you start.
