HelloPharmacist Scorecard of KingChlorella by Allergy Research Group

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 Aug 13, 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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

KingChlorella has two active ingredients. Chlorella pyrenoidosa is a freshwater algae rich in nutrients including vitamin K.

The product also contains Lactobacillus rhamnosus Lysate powder, a probiotic-related ingredient. There are 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 has been studied for several uses, but the evidence is mixed. It's considered possibly effective for pregnancy-related iron deficiency.

For brain tumor, nonalcoholic fatty liver disease (NAFLD), depression, and fatigue, the evidence isn't established enough to rate it — we simply don't have reliable data yet.

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, so choose carefully. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, photosensitivity (sun sensitivity), and dark-colored stool — especially in the first two weeks.

Serious allergic reactions including anaphylaxis are rare but have been reported. There isn't enough safety data overall, so avoid it unless your doctor approves.

In pregnancy, chlorella is considered possibly safe, but we don't have information on whether it's safe during breastfeeding — talk with your doctor or pharmacist before use.

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 you take this product, make sure your doctor or pharmacist knows if you're on warfarin (Coumadin) or another blood thinner — chlorella can make them less effective. Also let them know if you take any photosensitizing drugs (medications that make your skin more sensitive to sun).

No interactions are documented for the Lactobacillus rhamnosus Lysate powder ingredient.

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.

KingChlorella may be worth considering if you're interested in chlorella's nutritional profile and your doctor has cleared it, particularly if you're pregnant and iron-deficient. Skip it if you take warfarin or other blood thinners, or if you're on medications that increase sun sensitivity.

Check with your own doctor or pharmacist before starting, especially if you take any prescription medications or have allergies.

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.

KingChlorella by Allergy Research Group: Common Questions

Does KingChlorella by Allergy Research Group interact with any medications?
Yes. Based on its ingredients, KingChlorella 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?
KingChlorella contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 KingChlorella while pregnant?
Chlorella is considered possibly safe in pregnancy, so it may be an option if your doctor thinks you need it. Talk with your doctor or pharmacist first to make sure it's right for you.
What's the most common side effect?
Digestive upset is most typical — abdominal cramping, diarrhea, constipation, gas, and nausea happen fairly often, especially in the first couple of weeks. These usually settle down.
Does chlorella actually work for fatigue or depression?
The evidence isn't established yet. Chlorella has been studied for both, but we don't have enough reliable data to say whether it helps.
Can KingChlorella cause sun sensitivity?
Yes — chlorella can cause photosensitivity in some people. A few case reports describe swelling and rashes on sun-exposed skin after taking it. If that happens, protect your skin or stop and talk with your doctor.
Why does chlorella interact with warfarin?
Chlorella is high in vitamin K, which helps your blood clot. Warfarin works against clotting, so extra vitamin K can make it less effective at preventing clots. That's why it's important to tell your doctor if you take warfarin.
Is there anything else I should know about quality?
Product quality and purity vary widely across brands, so buy from a reputable maker. It's one reason to talk with your pharmacist before starting.
