HelloPharmacist Scorecard of Organic Neem Powder by Nova Nutritions

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 contains one active ingredient: certified organic neem powder. Neem (also called Indian lilac) is a plant extract traditionally used in Ayurvedic medicine.

The powder contains no added fillers or inactive ingredients.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Neem's overall clinical evidence instead.

Moderate

Some clinical evidence supports Neem for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Dental plaque — rated "Possibly Effective" (Natural Medicines).
  • On file: Gingivitis — rated "Possibly Effective" (Natural Medicines).
  • On file: Lice — rated "Possibly Effective" (Natural Medicines).

The evidence supports neem's use for a few specific concerns. It's possibly effective for gingivitis (inflamed gums) and dental plaque when used topically, and possibly effective against lice.

For acne and tungiasis (a parasitic skin infection), the evidence isn't established well enough to rate it. If you're thinking about neem for something else, the data we hold doesn't cover it — ask your doctor or pharmacist whether there's evidence for your particular use.

The evidence, ingredient by ingredient Neem

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.

Neem leaf powder appears generally well tolerated in adults when taken by mouth, though rigorous safety studies haven't been done. The main concern: neem oil and concentrated seed extracts can be toxic if swallowed, and neem oil can cause serious harm in children.

Topically, neem seems well tolerated, though sensitive skin may develop contact dermatitis. Rare serious effects with oral neem leaf in adults include heart rhythm problems and kidney damage; there's also a case report of hemolytic anemia (destruction of red blood cells) in someone with a blood disorder who drank large amounts of neem tea daily.

Neem should be avoided during pregnancy — the safety data advises against it. There isn't enough reliable information to know whether it's safe while breastfeeding, so it's best to skip it during that time too.

If you're pregnant, planning pregnancy, or breastfeeding, talk with your doctor or pharmacist before using this product.

Side effects, ingredient by ingredient Neem

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 — Neem.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,014 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 taking this product, double-check with your doctor or pharmacist if you take blood sugar-lowering drugs (like metformin), since neem may increase the risk of low blood sugar. You should also verify any medications that are broken down by your liver (CYP3A4, CYP2C9, CYP2C8, or CYP1A2 substrates), P-glycoprotein substrates, or immunosuppressants, because neem may raise their levels or reduce their effectiveness.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Neem powder is possibly effective for gum inflammation and lice, and is generally well tolerated topically. However, it interacts with a very large number of medications, especially blood sugar drugs, so it's not something to start casually if you take any prescriptions.

If you do take medications — particularly diabetes drugs or immune-suppressing drugs — check your list with the tool on this page and talk it over with your own doctor or pharmacist before you begin. Avoid it if you're pregnant or breastfeeding.

Organic Neem Powder by Nova Nutritions: Common Questions

Does Organic Neem Powder by Nova Nutritions interact with any medications?
Yes. Based on its ingredients, Organic Neem Powder has a known interaction with 1,013 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Organic Neem Powder 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.
What is neem, and what's it used for?
Neem, also called Indian lilac, is a plant used in traditional medicine. This powder is possibly effective for inflamed gums, dental plaque, and lice. The evidence for acne and other uses isn't well established.
Can I take neem if I'm on diabetes medication?
Not without talking to your doctor first. Neem can lower blood sugar, and if you're already taking diabetes drugs like metformin, combining them risks your blood sugar dropping too low. Your doctor or pharmacist can assess whether it's safe for your particular situation.
Is neem safe for children?
Neem leaf powder appears okay, but neem oil can cause serious harm if children swallow it. If you're considering neem for a child, talk with your pediatrician or pharmacist first.
Can I use this if I'm pregnant or breastfeeding?
No — neem should be avoided during pregnancy because safety data advises against it. There isn't enough reliable information about breastfeeding either, so it's best to skip it during that time. Talk with your doctor or pharmacist about safer alternatives.
What are the most common side effects?
Orally, neem leaf powder appears well tolerated in adults with minimal side effects reported. Topically (on skin), the main risk is contact dermatitis in sensitive individuals.
Does neem interact with a lot of medications?
Yes — neem affects several pathways your liver and cells use to process medications, which means it potentially interacts with a very large number of drugs. Use the search tool on this page to check your specific medications, and talk it over with your doctor or pharmacist before starting.
