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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product has two active ingredients: folic acid and bee pollen granules. Folic acid is a B vitamin your body uses to make new cells and support nerve function.

Bee pollen is a mixture of pollen, nectar, enzymes, and plant secretions collected by honeybees — it's used in supplements as a general wellness ingredient. There are no inactive fillers listed for this product.

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: nutritional supplement and energy support.
  • We looked for evidence on: Athletic performance, Physical performance, Folate deficiency, Anemia, General nutrition, Immune support.
  • The strongest evidence on file: Folic Acid is rated "Effective" for Folate deficiency (Natural Medicines).
  • Also on file: Bee Pollen is rated "Possibly Ineffective" for Athletic performance.
  • Also on file: Folic Acid is rated "Possibly Ineffective" for Anemia, Physical performance.

Folic acid is effective for treating folate deficiency and likely effective for reducing methotrexate toxicity and preventing neural tube birth defects — which is why it's recommended during pregnancy. It may help with depression, gum overgrowth from phenytoin, and cognitive impairment, though the evidence there is weaker.

Bee pollen's effectiveness is less clear. The data shows it's possibly ineffective for athletic performance, and there isn't enough reliable evidence to rate it for hay fever, absent periods, prostate health, or hot flashes.

The evidence, ingredient by ingredient Folic Acid Bee Pollen

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Folic acid is generally well tolerated at recommended doses for most adults. At the low end (under 1 mg daily), side effects are rare.

Higher doses (5 mg daily or more) can cause abdominal cramps, diarrhea, and rash; at 15 mg daily, bitter taste, confusion, hyperactivity, sleep trouble, and nausea have been reported. Rare serious effects include seizures, liver injury, and cardiovascular problems with long-term use.

Large doses can also worsen nerve damage (neuropathy) if you're low in vitamin B12, and folic acid can mask pernicious anemia symptoms, so don't self-treat anemia without a diagnosis. Bee pollen is well tolerated in most people but can trigger allergic reactions — sometimes severe — especially if you're allergic to ragweed or related plants.

Rare serious effects include acute liver inflammation, kidney failure, and anaphylaxis. There have been two cases of acute hepatitis tied to bee pollen use.

For pregnancy, folic acid is considered likely safe at standard prenatal doses, but bee pollen is possibly unsafe — the data advises against it. Folic acid is safe while breastfeeding at normal doses, but bee pollen safety is unknown, so it's best avoided.

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?
  • 2 of the 2 matched ingredients can interact with medications — Bee Pollen, Folic Acid.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 42 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 these drug types with your pharmacist before taking this product: seizure medications (phenobarbital, phenytoin, primidone) — folic acid may reduce their effectiveness and raise seizure risk. Cancer drugs (methotrexate, capecitabine, 5-fluorouracil) — folic acid may weaken their action or increase toxicity.

Blood thinners like warfarin — bee pollen may increase bleeding. Also ask about malaria and infection medications (pyrimethamine), as folic acid may blunt their effect.

The bottom line

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

This product is most useful if you need folic acid for folate deficiency or birth-defect prevention — though talk with your doctor about the right dose for you. If you take seizure medications, blood thinners, or cancer drugs, you need to check with your pharmacist before starting it.

Bee pollen adds little proven benefit and carries allergy risk.

Each ingredient & the kinds of drugs it affects

For each ingredient in Bee Pollen Granules with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Folic Acid7 drug types · 40 drugs

5-Fluorouracil

Theoretically, high doses of folic acid might increase the toxicity of 5-fluorouracil.
Increases in gastrointestinal side effects of 5-fluorouracil, such as stomatitis and diarrhea, have been described in two clinical studies when leucovorin, a form of folic acid, was administered with 5-fluorouracil.

Likelihood Possible Evidence D
Capecitabine (Xeloda)

Use of high-dose folic acid might contribute to capecitabine toxicity.
Clinical research suggests that higher serum folate levels are associated with an increased risk for moderate or severe toxicity during capecitabine-based treatment for colorectal cancer. Additionally, in one case report, taking folic acid 15 mg daily might have contributed to increased toxicity, including severe diarrhea, vomiting, edema, hand-foot syndrome, and eventually death, in a patient prescribed capecitabine.

Likelihood Possible Evidence D
Methotrexate (Trexall, Others)

Folic acid might reduce the efficacy of methotrexate as a cancer treatment when given concurrently.
Methotrexate exerts its cytotoxic effects by preventing conversion of folic acid to the active form needed by cells. There is some evidence that folic acid supplements reduce the efficacy of methotrexate in the treatment of acute lymphoblastic leukemia, and theoretically they could reduce its efficacy in the treatment of other cancers. Advise cancer patients to consult their oncologist before using folic acid supplements. In patients treated with long-term, low-dose methotrexate for rheumatoid arthritis (RA) or psoriasis, folic acid supplements can reduce the incidence of side effects, without reducing efficacy.

Likelihood Probable Evidence B
Phenobarbital (Luminal)

Folic acid might have antagonistic effects on phenobarbital and increase the risk for seizures.
Folic acid can have direct convulsant activity in some people, reversing the effects of phenobarbital and worsening seizure control. Monitor closely for increased seizure activity.

Likelihood Probable Evidence B
Phenytoin (Dilantin)

Folic acid might reduce serum levels of phenytoin in some patients.
Folic acid may be a cofactor in phenytoin metabolism. Folic acid, in doses of 1 mg daily or more, can reduce serum levels of phenytoin in some patients. Increases in seizure frequency have been reported. If folic acid supplements are added to established phenytoin therapy, monitor serum phenytoin levels closely. If phenytoin and folic acid are started at the same time and continued together, adverse changes in phenytoin pharmacokinetics are avoided. Note that phenytoin also reduces serum folate levels.

Likelihood Probable Evidence B
Primidone (Mysoline)

Folic acid might have antagonistic effects on primidone and increase the risk for seizures.
Folic acid can have direct convulsant activity in some people, reversing the effects of primidone and worsening seizure control. Monitor closely for increased seizure activity. Note that primidone also reduces serum folate levels.

Likelihood Probable Evidence B
Pyrimethamine (Daraprim)

Folic acid might antagonize the effects of pyrimethamine.
Folic acid can antagonize the antiparasitic effects of pyrimethamine against toxoplasmosis and Pneumocystis carinii pneumonia. Folic acid doesn't antagonize the effects of pyrimethamine in the treatment of malaria, because malarial parasites cannot use exogenous folic acid. Use folinic acid as an alternative to folic acid when indicated.

Likelihood Probable Evidence D
Folic Acid full monograph & interactions

Bee Pollen granules1 drug type · 2 drugs

Warfarin (Coumadin)

There is some concern that bee pollen might interact with warfarin and increase the risk of bleeding.
In one case report, a patient on warfarin had a stable international normalized ratio (INR) of 1.9-3.3 for 9 months. The patient's INR was found to be 7.1 after starting bee pollen granules one teaspoon twice daily for approximately one month. The patient's warfarin dose was decreased by approximately 11% in order to return the INR to the therapeutic range while continuing the bee pollen supplement.

Bee Pollen Granules by Vitamin World: Common Questions

Does Bee Pollen Granules by Vitamin World interact with any medications?
Yes. Based on its ingredients, Bee Pollen Granules has a known interaction with 42 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Bee Pollen Granules contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this safe to take while I'm pregnant?
Folic acid is considered likely safe and actually recommended at standard prenatal doses to help prevent birth defects. However, bee pollen is possibly unsafe in pregnancy — the safety data advises against it. Talk with your doctor or midwife about whether this product is right for you.
Can I take this if I have a pollen allergy?
Be careful. If you're allergic to ragweed, daisies, marigolds, chrysanthemums, or related plants, you're at risk for serious allergic reactions to bee pollen — including swelling, shortness of breath, and anaphylaxis. If you have a history of pollen allergies, avoid this product or talk with your allergist first.
What side effects might I notice?
At low doses, folic acid is generally well tolerated. At higher doses (5 mg daily or more), you might get abdominal cramps, diarrhea, or rash. At 15 mg daily, confusion, sleep problems, and nausea are more likely. Bee pollen is usually well tolerated but can trigger allergies in sensitive people.
Does bee pollen actually improve athletic performance?
The evidence shows bee pollen is possibly ineffective for athletic performance, so it's unlikely to boost your workouts or endurance.
I think I might have an iron deficiency. Can I use this product to self-treat?
No — don't self-treat suspected anemia with folic acid. Folic acid can mask the symptoms of pernicious anemia (a serious B12 deficiency), which can lead to permanent nerve damage if left untreated. Get a proper diagnosis from your doctor first.
Is it safe to take while breastfeeding?
Folic acid is considered safe at normal recommended doses while breastfeeding. Bee pollen safety is unknown while nursing, so it's best avoided — talk with your doctor or lactation consultant.
