HelloPharmacist Scorecard of Neem Leaf SAP by NFH

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.

Neem Leaf SAP contains one active ingredient: neem leaf. The product also includes inactive ingredients — vegetable magnesium stearate, silicon dioxide, vegetable hypromellose, and purified water — which are used as fillers and to form the capsule.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: relieve fever and skin conditions, promote digestion.
  • We looked for evidence on: Acne, Psoriasis, Dyspepsia, Dental plaque, Gingivitis, Wound healing — and 4 related terms.
  • The strongest evidence on file: Neem is rated "Possibly Effective" for Dental plaque (Natural Medicines).
  • Also on file: Neem is rated "Possibly Effective" for Gingivitis.
  • Also on file: Neem is rated "Insufficient Reliable Evidence To Rate" for Acne, Dyspepsia, Psoriasis, Wound healing.

Neem leaf is possibly effective for gingivitis and for head lice. It may help reduce dental plaque.

For acne and tungiasis (a parasitic skin infection), the evidence isn't established in the data we hold.

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 in adults when taken by mouth, though high-quality safety studies haven't been done. Topically, neem seems well tolerated in both children and adults, with contact dermatitis the main side effect in sensitive individuals.

However, neem is not recommended in pregnancy — the safety data advises against it. There isn't enough reliable information to know if it's safe while breastfeeding, so talk with your doctor or pharmacist.

Importantly, neem oil (as opposed to leaf) can be toxic if swallowed, especially in children, so make sure you're using a leaf product as labeled.

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 with your doctor or pharmacist before using this product if you take antidiabetes medications (the most serious concern), immunosuppressants, or any drug that your liver breaks down, including most cholesterol and blood pressure medications. Neem may slow how your body clears these drugs and raise their levels.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Neem leaf may help with gum disease, plaque, or lice if the evidence resonates with you. But it's a serious interaction risk if you take diabetes medications, immunosuppressants, or drugs your liver processes heavily — and it's off-limits in pregnancy and breastfeeding.

Talk it over with your doctor or pharmacist before you start, especially if you're on any regular medications.

Neem Leaf SAP by NFH: Common Questions

Does Neem Leaf SAP by NFH interact with any medications?
Yes. Based on its ingredients, Neem Leaf SAP 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 Leaf SAP 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 leaf if I take metformin for diabetes?
No — talk with your doctor first. Neem can lower blood glucose, and there's clinical evidence it does so even in people already on metformin, so taking both together raises your risk of low blood sugar (hypoglycemia). Your doctor may need to adjust your dose or monitor you closely.
Is neem leaf safe to use while I'm pregnant or breastfeeding?
No, the safety data advises against neem in pregnancy. While breastfeeding, there isn't enough reliable information to know either way, so talk with your doctor or pharmacist for personalized advice.
Does neem leaf really work for gingivitis and plaque?
Neem is possibly effective for both gingivitis and dental plaque based on the evidence we hold. It's also possibly effective for head lice if that's something you're treating.
What side effects might I notice if I take neem leaf by mouth?
Most people tolerate neem leaf extracts well when taken orally. Topically, the main side effect is contact dermatitis (a skin rash) in people who are sensitive to it. Rare serious side effects have been reported, including heart rhythm problems and kidney issues, but high-quality safety data in humans is limited.
Why does the product say to avoid neem oil but this is neem leaf?
Neem oil can be toxic if swallowed, especially in children. This product is neem leaf, which is much safer when taken by mouth, though you should still check with your pharmacist or doctor before starting, especially if you're on medications.
