HelloPharmacist Scorecard of Chlorella Alcohol Free by Herbal Terra

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 entire plant extract in dry form. Chlorella is a single-celled green algae.

The liquid is made with glycerin and water as inactive ingredients.

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 possibly effective evidence for pregnancy-related iron deficiency. For other uses listed here — brain tumors, fatty liver disease, depression, and fatigue — the evidence isn't established well enough in our data to rate it.

That doesn't mean it won't help; it means more reliable research is needed.

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 across brands, so choose carefully. The most common side effects are allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, gas, nausea, and skin sensitivity to sun (photosensitivity).

Most happen early, especially in the first two weeks. Serious allergic reactions including anaphylaxis are rare but have been reported.

There isn't enough safety data on long-term use, so don't take this without your doctor's approval.

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 with your pharmacist if you take warfarin (Coumadin) or any photosensitizing drugs — drugs that make your skin more sensitive to sunlight. Warfarin effectiveness may drop; photosensitizing drugs may have additive effects with chlorella.

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 with iron deficiency, but the evidence for other uses is thin. Before you start, check with your pharmacist if you take warfarin or any drug that increases sun sensitivity — those interactions could be real problems.

Quality varies, so stick with a reputable brand and watch for stomach upset or skin reactions in the first couple of weeks.

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 Alcohol Free by Herbal Terra: Common Questions

Does Chlorella Alcohol Free by Herbal Terra interact with any medications?
Yes. Based on its ingredients, Chlorella Alcohol Free 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 Alcohol Free 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.
What side effects might I notice?
Most people experience gas, nausea, stomach cramping, or diarrhea, especially in the first two weeks. Some notice sun sensitivity or allergic reactions. Serious allergic reactions are rare. If you develop rash, swelling, or trouble breathing, stop and call your doctor.
Is chlorella safe during pregnancy?
We don't have safety data on file for pregnancy or breastfeeding, so talk with your doctor before using it — even though chlorella may help with pregnancy-related iron deficiency. Your doctor can weigh the evidence for your situation.
Can I take this long-term?
Chlorella is generally well tolerated short-term, but we don't have enough safety data for long-term use. Don't take it unless your doctor approves, especially if you plan to use it for weeks or months.
Does chlorella actually work?
It has possibly effective evidence for pregnancy-related iron deficiency. For brain tumors, fatty liver disease, depression, and fatigue, the evidence isn't established yet in our data — we just don't know enough to say either way.
What's in this liquid besides the active ingredient?
The inactive ingredients are glycerin and water. There are no other fillers or binders.
Is product quality consistent across brands?
No. Chlorella product quality and purity vary widely, so choose a reputable brand carefully. This matters because contamination or inconsistent strength could affect your results or safety.
