HelloPharmacist Scorecard of Royal Jelly 500 mg by Nature's Blend

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 Jul 11, 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.

Royal Jelly 500 mg contains one active ingredient: royal jelly concentrate, which is the nutrient-rich secretion made by honeybees. The supplement comes in a softgel capsule made with gelatin, soybean oil, glycerin, beeswax, soy lecithin, titanium dioxide, riboflavin, and purified water.

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: Royal Jelly nutrient and general wellness support.
  • We looked for evidence on: Menopausal symptoms, Dry eye, Athletic performance, Physical performance, Energy and vitality, Skin health — and 1 related terms.
  • The strongest evidence on file: Royal Jelly is rated "Possibly Effective" for Menopausal symptoms (Natural Medicines).
  • Also on file: Royal Jelly is rated "Possibly Ineffective" for Physical performance.
  • Also on file: Royal Jelly is rated "Insufficient Reliable Evidence To Rate" for Athletic performance, Dry eye.

Royal jelly is possibly effective for menopausal symptoms. However, the evidence we hold shows it's possibly ineffective for hay fever and physical performance.

For hair loss (androgenic alopecia), there isn't enough reliable evidence to rate how well it works.

The evidence, ingredient by ingredient Royal Jelly

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.

Royal jelly is generally well tolerated, but it does carry a serious risk if you're allergic to bee products. If you have a history of asthma or atopy (a tendency toward allergic reactions), you're at higher risk for allergic symptoms like itching, hives, swelling, shortness of breath, and oral allergy syndrome.

In rare cases, it can cause severe reactions like anaphylaxis or status asthmaticus (a dangerous asthma attack). There isn't enough safety information to recommend royal jelly during pregnancy or while breastfeeding.

Talk with your doctor or pharmacist about whether it's right for you in those situations.

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.

Royal Jelly 500 mg may help with menopausal symptoms, but it's not for everyone. If you take warfarin or blood pressure medications, you'll want to check with us before starting.

And if you have asthma or a history of allergies to bee products, this isn't a good choice for you.

Royal Jelly 500 mg by Nature's Blend: Common Questions

Does Royal Jelly 500 mg by Nature's Blend interact with any medications?
Yes. Based on its ingredients, Royal Jelly 500 mg has a known interaction with 174 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Royal Jelly 500 mg 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 take Royal Jelly if I have asthma?
No — if you have asthma or a history of allergic reactions (atopy), royal jelly can trigger serious symptoms like itching, hives, shortness of breath, and in rare cases, life-threatening reactions. Talk to your doctor before considering it.
What does royal jelly actually do?
Royal jelly is possibly effective for easing menopausal symptoms. For other uses like boosting athletic performance or treating hay fever, the evidence we have suggests it doesn't work well. For hair loss, there isn't enough data to say either way.
Is it safe to take while I'm pregnant?
There isn't enough safety information about royal jelly in pregnancy. Talk with your doctor or pharmacist for personalized advice — they can weigh the risks and benefits for your situation.
What are the side effects?
Most people tolerate it well. But if you're sensitive to bee products, you might experience itching, hives, eczema, or swelling of the face and eyelids. Serious allergic reactions are rare but possible in people with asthma or a history of allergies.
Can I take this with warfarin?
Not without checking first — royal jelly may increase your bleeding risk when you're on warfarin. We've seen a case where someone developed serious bleeding complications after just one week on the supplement. Your doctor or pharmacist needs to weigh this with you.
