HelloPharmacist Scorecard of Organic Neem Powder 1 g by Vitamatic Organics

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Aug 27, 2026

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: neem powder — the dried leaf material from the neem tree. There are no inactive ingredients listed.

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).

Neem leaf is possibly effective for gingivitis (gum inflammation) and lice. It may also help with dental plaque, though the evidence is also rated possibly effective.

For acne and tungiasis (a parasitic skin infection), we don't have enough reliable evidence yet to know if it works.

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 is generally well tolerated when taken by mouth in adults, though formal high-quality safety studies haven't been done. Topically, it's also generally well tolerated in both children and adults, though sensitive skin may develop contact dermatitis.

However, safety is a real concern for certain groups: neem is likely unsafe in pregnancy and should be avoided — it may affect fertility and pregnancy outcomes. There isn't enough reliable safety data to recommend it while breastfeeding, so it's best avoided then too.

In children, neem oil taken by mouth can cause serious harm. Rare but serious side effects reported in adults include cardiac arrest, kidney damage, and irregular heartbeats; one case involved a person with a glucose-6-phosphate dehydrogenase (G6PD) deficiency who developed hemolytic anemia after drinking 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.

Before taking this product, check with your doctor or pharmacist if you take blood sugar drugs — neem can lower blood glucose further and may increase the risk of low blood sugar. Also confirm if you're on immunosuppressants, or any medications broken down by your liver (a very wide group that includes many common drugs).

No interactions are documented in our data for topical use, but oral neem powder carries these risks.

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 may help with gum health and lice, but it's not right for everyone. If you take any blood sugar medications, immunosuppressants, or drugs metabolized by your liver, talk with your doctor or pharmacist before adding this — the interactions are real, even if they haven't been widely reported in people yet.

Skip it entirely if you're pregnant or breastfeeding. Check your medications first.

Organic Neem Powder 1 g by Vitamatic Organics: Common Questions

Does Organic Neem Powder 1 g by Vitamatic Organics interact with any medications?
Yes. Based on its ingredients, Organic Neem Powder 1 g 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 1 g 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 use neem powder while pregnant or breastfeeding?
No — neem is likely unsafe in pregnancy and may affect fertility. While breastfeeding, there isn't enough safety data, so it's best avoided then too. Talk with your doctor or pharmacist if you're planning pregnancy or are currently pregnant or breastfeeding.
What's neem powder actually used for?
Neem powder is possibly effective for gingivitis (inflamed gums), lice, and dental plaque. For acne and other skin conditions, we don't have enough reliable evidence yet.
Are there any side effects I should know about?
Most adults tolerate neem leaf powder well. The most common issue topically is contact dermatitis in sensitive skin. Serious side effects are rare in adults but have been reported, including cardiac problems and kidney damage. In children, neem oil taken by mouth can cause serious harm.
I take metformin for diabetes — is neem safe for me?
No — neem can lower blood sugar on its own, and research shows it can do this even in people already on metformin. This raises the risk of dangerously low blood sugar. Talk with your doctor or pharmacist before using it.
Does this product have any fillers or other ingredients?
No — this is just neem powder with no inactive ingredients listed.
I'm on a lot of medications. How do I know if neem will interfere?
Use the interaction checker on this page with your exact medication list — neem can theoretically affect how your body processes many common drugs through your liver. Confirm with your doctor or pharmacist before you start.
