HelloPharmacist Scorecard of Neem by Village Vitality

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: organic neem leaf extract in capsule form. Neem is a tree native to India whose leaves have been used traditionally for oral health, skin, and other purposes.

The capsule itself contains modified vegetable cellulose as an inactive ingredient.

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 leaf for gingivitis and dental plaque — both are rated possibly effective based on available research. It's also rated possibly effective for lice.

For acne and tungiasis (a parasitic skin infection), the evidence isn't established enough to rate it. If you're thinking about neem for any of these, talk it over with your doctor or pharmacist about whether it's right for your situation.

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 preparations appear generally well tolerated when taken by mouth short-term in adults, though high-quality safety studies haven't been done. The main concern is that neem oil and seed extracts can be toxic if swallowed — this product is a leaf extract, but that distinction matters.

Topically, neem seems well tolerated in both children and adults; the main side effect is contact dermatitis in sensitive skin. Neem is not safe in pregnancy — the data advises against it.

It's also best avoided while breastfeeding because there isn't enough reliable safety information. In children, oral neem oil has caused serious adverse effects and should not be given.

There have been rare case reports of serious effects in adults taking neem leaf, including cardiac issues and kidney damage, and one case of hemolytic anemia (breakdown of red blood cells) in a person with a specific genetic condition who drank large amounts of neem tea daily.

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.

Check before taking neem if you use blood sugar medications (diabetes drugs) — neem may lower blood glucose and increase the risk of hypoglycemia. Also double-check if you take medications processed through CYP3A4, CYP1A2, CYP2C9, CYP2C8, or P-glycoprotein pathways, or immunosuppressants, as neem may theoretically raise their levels or reduce their effectiveness.

These theoretical interactions haven't been reported in humans yet, but the lab evidence warrants caution.

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 leaf may help with gum disease, plaque, or lice if the research holds up for your situation. But it interacts with a very large number of medications, particularly blood sugar drugs and those processed by your liver, so you'll want to check your exact prescriptions before starting.

If you're pregnant, breastfeeding, or taking immunosuppressants or diabetes medications, talk with your doctor or pharmacist first.

Neem by Village Vitality: Common Questions

Does Neem by Village Vitality interact with any medications?
Yes. Based on its ingredients, Neem 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?
Neem 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 neem safe to take while pregnant or breastfeeding?
No — neem is rated likely unsafe in pregnancy and should be avoided. While breastfeeding, there isn't enough reliable safety data, so it's best avoided as well. If you're pregnant or breastfeeding and interested in neem, talk with your doctor or pharmacist.
What's the difference between neem leaf and neem oil?
This product is a neem leaf extract. Neem oil and seed extracts can be toxic if swallowed — especially dangerous in children — whereas leaf preparations are generally well tolerated in adults when taken short-term. That said, serious side effects with neem leaf have been rarely reported even in adults.
Does neem actually help with gum disease and plaque?
Yes — research supports neem for gingivitis and dental plaque; both are rated possibly effective. It's also rated possibly effective for lice. The evidence for acne and tungiasis isn't established yet.
Can I take neem if I'm on diabetes medication?
You need to check with your doctor or pharmacist first. Neem can lower blood glucose on its own, and clinical research shows this happens even in people already taking metformin. Combining it with your diabetes drug could raise your risk of low blood sugar (hypoglycemia).
What are the common side effects of neem?
When taken by mouth, neem extract appears well tolerated in most adults, though safety studies haven't been thorough. Topically, the main side effect is contact dermatitis (skin irritation) in people with sensitive skin. Rare serious effects in adults have included cardiac and kidney issues.
Is this product free of fillers?
This capsule contains one inactive ingredient: modified vegetable cellulose, which is part of the capsule material itself. So no, it's not filler-free, though it's a minimal amount.
