HelloPharmacist Scorecard of Agar Agar 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 Oct 8, 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, agar agar extract (dry powder), which is the source of its effect. Agar is a fiber-like substance that forms a gel when mixed with liquid.

Its listed inactive ingredients are glycerin and water.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Agar product and its label doesn't state a use — see Agar's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

Our data rates agar as having insufficient reliable evidence to judge its effectiveness for diabetes, obesity, and neonatal jaundice (jaundice in newborns). In other words, the evidence for these uses isn't established in the data we hold.

The evidence, ingredient by ingredient Agar

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.

Agar is generally well tolerated in normal food amounts. Our safety notes say supplement doses should be taken with plenty of water, and that there is little safety data on supplement doses.

Oral use has not been fully evaluated, though no adverse effects have been reported. Rarely, high-fiber foods like agar have been linked to blockages in the esophagus or bowel, especially when not enough fluid is taken.

Side effects, ingredient by ingredient Agar

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Agar.
  • The most serious interaction on file is rated Minor.
  • For scale: 2,023 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.

Oral drugs, which are medications taken by mouth, are the only drug type with a documented interaction for this product, rated Minor. Because agar can affect how well medications are absorbed, double-check any oral medication with your own doctor or pharmacist before taking this product.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

This product may be of interest to someone looking for a fiber-based gel supplement, but the evidence for its uses is not established. If you take oral medications, or you have a condition affecting your digestion, talk it over with your own doctor or pharmacist before starting.

Be sure to drink plenty of water with each dose.

Oral Drugs

Agar forms a thick gel, which may disrupt the absorption of nutrients and medications. Animal research suggests that consuming a diet consisting of 5% to 10% agar alters the absorption of nutrients from the diet. In one study, consuming a diet composed of 10% agar reduced the absorption of all evaluated minerals. Theoretically, agar may also impair the absorption of oral drugs.

Yes. Based on its ingredients, Agar Agar Alcohol Free has a known interaction with 2,022 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Agar Agar 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.
Is there enough data on pregnancy or breastfeeding use?

What are the side effects of agar?
No adverse effects have been reported when taken orally, though a full safety evaluation hasn't been done. Rarely, blockages in the esophagus or bowel have been reported with high-fiber foods like agar, especially when not enough fluid is consumed.
Does agar work for weight loss or diabetes?
Our data rates the evidence as insufficient reliable evidence to rate for both obesity and diabetes. That means its effectiveness for these uses isn't established in the data we hold.
