HelloPharmacist Scorecard of Noni 400 mg by Maui Medicinal

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.

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: dried noni fruit at 400 mg per capsule. The capsule itself is made from vegetable material.

Noni is a tropical fruit traditionally used in Pacific and Southeast Asian medicine, though its effectiveness for most modern health claims remains unproven in rigorous studies.

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 Noni product and its label doesn't state a use — see Noni'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 doesn't establish that noni is effective for the conditions listed — asthma, atherosclerosis, athletic performance, burns, cancer, and cardiovascular disease all carry a rating of insufficient reliable evidence. That means the science isn't there yet to say whether it works for these purposes.

The evidence, ingredient by ingredient Noni

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.

Noni is generally well tolerated when taken by mouth in moderate amounts, though the most common side effects are nausea and abdominal discomfort. The main safety concerns are rare but serious: liver damage (hepatotoxicity) has been reported in previously healthy people, and because noni contains high amounts of potassium, it poses a risk if you have kidney problems or take certain blood pressure medications.

The safety data advises against noni use during pregnancy because it has been traditionally used to cause abortion. There isn't enough safety information available for breastfeeding — talk with your doctor or pharmacist about whether it's right for you in that situation.

Side effects, ingredient by ingredient Noni

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 — Noni.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 543 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.

Before starting Noni 400 mg, double-check with your doctor or pharmacist if you take blood pressure medications (antihypertensives), potassium-sparing diuretics, ACE inhibitors, or ARBs — all are Moderate concerns. Also confirm if you're on warfarin, phenytoin, any liver-stressing drugs, or ranitidine.

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.

Noni may be worth considering if you're curious about traditional Pacific remedies and have no blood pressure, heart, kidney, or liver concerns — but the evidence doesn't yet support it for most modern health claims. If you take any prescription medications, especially blood pressure drugs, blood thinners, seizure medications, or anything that affects potassium or liver function, check with your doctor or pharmacist before adding this supplement.

Avoid it if you're pregnant.

dried Noni8 drug types · 542 drugs

Ace Inhibitors (Aceis)

Theoretically, combining noni and ACE inhibitors might increase the risk of hyperkalemia.
Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice. This may increase the risk for hyperkalemia when used in conjunction with ACE inhibitors, which can also increase potassium levels.

Likelihood Possible Evidence D
Angiotensin Receptor Blockers (Arbs)

Theoretically, combining noni and ARBs might increase the risk of hyperkalemia.
Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice. This may increase the risk for hyperkalemia when used in conjunction with ARBs, which can also increase potassium levels.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, noni may increase the risk of hypotension when used in combination with antihypertensive drugs.
Preliminary clinical research suggests that drinking noni juice can reduce blood pressure in individuals with hypertension.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, taking noni with hepatotoxic drugs might increase the risk of liver damage.
There is concern that noni might cause hepatotoxicity in some patients. Advise patients against combining noni with potentially hepatotoxic drugs.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Theoretically, taking noni fruit juice concomitantly with phenytoin may lower phenytoin levels and increase the risk of seizures.
In one case report, an adult taking phenytoin for partial seizures experienced low serum phenytoin levels while taking noni juice 90-200 mL daily. Serum phenytoin levels increased after decreasing noni juice consumption; similarly, serum phenytoin levels decreased after increasing noni juice consumption. Some researchers believe noni juice may induce cytochrome P450 2C9 enzymes, which would decrease phenytoin levels, but this has not been well studied. Patients may need additional monitoring when starting or stopping noni juice supplementation.

Likelihood Possible Evidence D
Potassium-Sparing Diuretics

Theoretically, combing noni and a potassium-sparing diuretic might increase the risk of hyperkalemia.
Noni juice contains significant amounts of potassium, about 6 mEq/100 mL juice. This may increase the risk for hyperkalemia when used in conjunction with potassium-sparing diuretics, which can also increase potassium levels.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, taking noni juice concomitantly with warfarin might decrease the effectiveness of warfarin.
In one case, a 41-year-old patient stabilized on warfarin had a decreased international normalized ratio (INR) following consumption of a specific commercial noni juice product (Noni juice 4 Everything). While the patient was still taking noni juice, an increase in warfarin dose did not produce an increase in INR. However, it should be noted that this particular product contained extracts and derivatives from more than 115 components, many of which contained vitamin K. Furthermore, vitamin K was listed as a separate ingredient of the product, suggesting that the product was possibly fortified with vitamin K. It has not been verified that noni fruit alone contains a significant amount of vitamin K or interacts with warfarin.

Likelihood Possible Evidence D
Ranitidine (Zantac)

Taking noni fruit with ranitidine might increase the levels and clinical effects of ranitidine.
Clinical evidence shows that taking an aqueous extract of noni fruit 30 minutes prior to taking a single oral dose of ranitidine can increase the rate of absorption and plasma concentration of ranitidine.

Noni 400 mg by Maui Medicinal: Common Questions

Does Noni 400 mg by Maui Medicinal interact with any medications?
Yes. Based on its ingredients, Noni 400 mg has a known interaction with 542 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Noni 400 mg 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 noni safe to take while I'm pregnant?
No. The safety data advises against noni use during pregnancy because it has traditionally been used to cause abortion. Talk with your doctor or pharmacist before taking it if you're pregnant or planning to become pregnant.
What are the most common side effects?
The most common side effects when taking noni by mouth are nausea and abdominal discomfort. Serious liver damage is rare but has been reported, so watch for signs of liver problems and tell your doctor if they develop.
Does noni actually work for cancer, asthma, or heart disease?
The evidence we have isn't strong enough to say whether noni works for those conditions. All of them carry a rating of insufficient reliable evidence, which means rigorous studies haven't been done or haven't shown benefit yet.
Why does noni interact with so many blood pressure and heart medications?
Noni juice contains a lot of potassium. Potassium-sparing diuretics, ACE inhibitors, and ARBs all raise potassium levels too, so combining noni with any of them could push your potassium dangerously high. Noni also appears to lower blood pressure on its own, which can be risky if your medication already does that.
Can I take noni with warfarin?
It's risky without checking with your doctor first. One case report showed noni juice decreased warfarin's effectiveness, which could reduce its ability to prevent clots. Your doctor or pharmacist needs to know if you're taking both so they can monitor you closely.
