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.

Lai Fu Zi is a single-ingredient supplement: radish seed extract in a liquid form. The extract is concentrated from the dried seed, so you're getting more radish compounds per dose than you'd get from eating the whole vegetable.

The liquid is made with alcohol, water, and glycerin as inactive ingredients to deliver 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 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 we hold does not establish whether radish seed extract works for biliary disorders or diabetes — both are rated insufficient reliable evidence to rate. That doesn't mean it doesn't help; it means clinical trials strong enough to prove it either way aren't in our data yet.

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. However, the safety profile of concentrated radish supplements hasn't been studied thoroughly, so caution is warranted at higher doses.

A rare case of allergy has been reported, with symptoms of throat tightness and hives. Large amounts may cause mild indigestion or irritate your stomach lining.

Pregnancy and lactation safety data isn't on file for radish. If you're pregnant or nursing, talk with your doctor or pharmacist about whether this product is right for you — they can weigh the limited data against your individual needs.

Side effects, ingredient by ingredient Radish

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 medication — insulin, metformin, sulfonylureas, or any other blood sugar drug — flag this product with your pharmacist or doctor before using it. They'll want to monitor your glucose levels or adjust your dose if you decide to use both together.

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.

Lai Fu Zi is a straightforward radish seed extract liquid that's generally well tolerated at food-level doses. The main caution is if you take diabetes medication — the two together might lower your blood sugar more than intended.

Check your exact medications and blood sugar control plan with your doctor or pharmacist before adding this to your routine.

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.
Can I take this if I'm on metformin or another diabetes drug?
Not without checking first. Radish may lower blood sugar on its own, so combining it with diabetes medication could push your levels too low. Talk to your doctor or pharmacist — they may want to monitor your glucose or adjust your medication if you use them together.
Is radish safe to take regularly?
At normal food amounts, yes — radish is eaten widely and is well tolerated. But safety data for concentrated supplements like this one is limited, so use caution at higher doses and avoid unwashed raw sprouts.
Does this actually help with diabetes or biliary issues?
We don't have reliable clinical evidence yet that radish seed extract works for either condition. Animal research is promising, but human trials strong enough to prove benefit aren't in our data.
What are the side effects?
Most people tolerate it fine. Large amounts may cause mild stomach irritation or indigestion. A rare allergy to radish has been reported, with throat tightness and hives. If you notice anything unusual, stop and talk to your pharmacist.
Is it safe during pregnancy or while breastfeeding?
We don't have safety data for concentrated radish supplements in pregnancy or lactation. If you're pregnant or nursing, talk with your doctor or pharmacist — they can help you decide what's best for you and your baby.
