From our pharmacy team — supplement deep dive

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.

Hawaii Pharm Duckweed is a single-ingredient liquid: duckweed extract. The product also contains vegetable palm glycerin and alcohol as inactive ingredients to preserve and carry the extract.

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 Duckweed product and its label doesn't state a use — see Duckweed'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.

The evidence we hold rates duckweed extract as having insufficient reliable evidence to rate for respiratory tract infections, rheumatoid arthritis (RA), and gout. In plain terms: we don't have solid data yet on whether it actually works for these uses.

If you're thinking about using it for one of these conditions, talk it over with your doctor or pharmacist — they can help you weigh what limited evidence exists against other options.

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Duckweed is considered a food in some cultures, but supplement quality and water contamination are real concerns with plant-based products. The safety data we hold advises against using this product — there isn't enough reliable information to know whether it's safe.

Safety during breastfeeding has not been established, so breastfeeding is not recommended while taking it. We hold no adverse-effect data for duckweed extract in our records.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. No medication interactions are currently documented, and some safety-information gaps remain.

Hawaii Pharm Duckweed extract has no documented medication interactions, but the safety evidence is weak enough that the data advises caution or avoidance. If you're pregnant or breastfeeding, it's not recommended.

Before you take this product — especially if you rely on it regularly — talk it over with your doctor or pharmacist to make sure it fits your individual health picture.

Duckweed by Hawaii Pharm: Common Questions

Does Duckweed by Hawaii Pharm interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Duckweed. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Duckweed 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 duckweed safe to take while breastfeeding?
No — safety during breastfeeding has not been established, so breastfeeding is not recommended while taking Hawaii Pharm Duckweed. Talk with your doctor or pharmacist about whether this product is right for you.
Can I take this if I'm pregnant?
We hold no pregnancy safety data for duckweed extract on file. Because safety information is limited, talk with your doctor or pharmacist before taking it — they can give you personalized advice based on your situation.
Does duckweed actually work for respiratory infections or rheumatoid arthritis?
We don't have reliable evidence yet on whether it does. The data we hold rates it as insufficient evidence to rate for both conditions, meaning the studies aren't solid enough to say. Your doctor can discuss other options with you that have stronger evidence behind them.
What are the side effects?
We hold no adverse-effect data for duckweed extract in our records. That doesn't mean it has none — it means we don't have trial or safety information on file about side effects.
Does this product contain anything besides duckweed?
The active ingredient is duckweed extract. It also contains vegetable palm glycerin and alcohol as inactive ingredients to preserve and carry the extract.
