HelloPharmacist Scorecard of Lai Fu Zi by Hawaii Pharm

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

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 has one active ingredient: certified organic Lai Fu Zi extract, which is radish. Radish is a root vegetable that's been used traditionally, and this liquid form makes it concentrated compared to eating radish as food.

The inactive ingredients are vegetable palm glycerin, pharmaceutical-grade alcohol, and artesian Hawaiian purified water — standard carriers for a liquid 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 Radish product and its label doesn't state a use — see Radish'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 for radish as a supplement isn't established in the data we hold. For biliary disorders and diabetes, we have insufficient reliable evidence to rate whether it actually works.

While animal studies suggest radish can lower blood sugar, we don't have the clinical trial evidence needed to say it's effective for people.

The evidence, ingredient by ingredient Radish

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.

Radish is widely eaten as food and is generally well tolerated in normal dietary amounts. That said, concentrated supplements are less studied than whole food, so the safety profile isn't as clear at higher doses.

Large amounts may irritate your stomach lining or cause mild indigestion. Raw sprouts — whether radish or any other kind — should be avoided because of contamination risk.

A rare allergy to radish has been reported, with symptoms including throat tightness and hives.

Side effects, ingredient by ingredient Radish

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 — Radish.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 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.

If you take any antidiabetes drug — insulin, metformin, glyburide, or others — check with your pharmacist before using this product. Radish can theoretically increase the risk of low blood sugar, a Moderate interaction.

No other medication interactions are documented for the ingredients we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you eat radish regularly as food, this liquid extract is a concentrated form of something you already tolerate. But if you take diabetes medication, you need to check with your pharmacist first — radish can lower blood sugar and might push your levels too low.

Otherwise, for healthy people with no diabetes drugs, the main watch-out is stomach upset from larger amounts.

Antidiabetes Drugs

Theoretically, radish might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that radish extract, juice, and sprouts can reduce glucose levels. Animal research also shows that radish root juice 300 mg/kg reduces fasting and postprandial blood glucose in a rat model of diabetes, with effects similar to glibenclamide.

Lai Fu Zi by Hawaii Pharm: Common Questions

Does Lai Fu Zi by Hawaii Pharm interact with any medications?
Yes. Based on its ingredients, Lai Fu Zi has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Lai Fu Zi 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.
Will this radish extract actually help my blood sugar or digestion?
The evidence isn't there yet. Animal studies suggest radish *might* lower blood sugar, but we don't have reliable clinical trial data in people for either diabetes or biliary disorders — so we can't say whether it actually works.
Can I take this if I'm pregnant or breastfeeding?
The safety data we have doesn't cover pregnancy or breastfeeding. Since this is a concentrated supplement (not just eating radish as food), talk with your doctor or pharmacist to decide what's right for you.
What are the side effects?
Most people tolerate radish well. Larger amounts can irritate your stomach or cause mild indigestion. A rare allergy has been reported — throat tightness and hives. If you notice either, stop and talk to your pharmacist.
Is this safe compared to eating regular radish?
Radish as a food is very safe. This liquid extract is more concentrated, so while it should be well tolerated, the safety of the supplement form at higher doses isn't as thoroughly studied as whole food.
Does it have fillers or other ingredients I should know about?
The active ingredient is the radish extract. It's mixed with vegetable palm glycerin, pharmaceutical-grade alcohol, and purified water — standard carriers for liquid supplements.
