HelloPharmacist Scorecard of Her Majesty's Royal Jelly by Cardiovascular Research

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 6, 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.
  • “Royal Jelly” is listed as a grouped ingredient — the label gives one combined amount (500 mg) without saying how much of each component you get.

This product contains one active ingredient: royal jelly concentrate, a nutrient-rich secretion from honeybees. The softgel also holds inactive ingredients including soybean oil, gelatin, yellow beeswax, glycerin, and soy lecithin.

Does it work?

Couldn't assess
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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: natural source of vitamins amino acids and nutrients.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Royal jelly is possibly effective for menopausal symptoms based on the evidence we hold. For hay fever, diabetes, and physical performance, the data suggests it is possibly ineffective.

For hair loss (androgenic alopecia), there isn't enough reliable evidence to say whether it works or doesn't.

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 by most people, but it can trigger serious allergic reactions in those who are sensitive — particularly anyone with a history of asthma or atopy (a tendency toward allergic conditions). Common allergic symptoms include itching, hives, eczema, shortness of breath, and oral allergy syndrome.

In rare cases, it can cause severe reactions like anaphylaxis or status asthmaticus (acute asthma). There is also one reported case of bleeding in the colon after taking royal jelly, though symptoms resolved after stopping it.

The safety data advises against royal jelly during pregnancy and while breastfeeding, as there isn't enough information to know whether it's safe in those settings.

Side effects, ingredient by ingredient Royal Jelly

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 — Royal Jelly.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 174 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.

If you take warfarin or any blood pressure medication, check with your doctor or pharmacist before using this product. Royal jelly can increase bleeding risk on warfarin and may lower blood pressure further if you're already on blood pressure drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Her Majesty's Royal Jelly may be worth considering if you're looking for help with menopausal symptoms, but it's not established to work for hay fever, diabetes, or physical performance. If you take blood pressure medication or warfarin, you'll need to check with your own doctor or pharmacist before starting — the interaction potential is real.

Anyone with asthma or a history of allergies should be especially cautious, since serious allergic reactions, though rare, are possible.

Her Majesty's Royal Jelly by Cardiovascular Research: Common Questions

Does Her Majesty's Royal Jelly by Cardiovascular Research interact with any medications?
Yes. Based on its ingredients, Her Majesty's Royal Jelly 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?
Her Majesty's Royal Jelly 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 this if I have asthma or allergies?
If you have a history of asthma or atopy (allergic tendency), be very cautious. Royal jelly causes allergic reactions in many people with these conditions — itching, hives, shortness of breath, and in rare cases, severe reactions like anaphylaxis. Talk with your doctor or pharmacist before trying it.
Is royal jelly safe during pregnancy or breastfeeding?
There isn't enough safety information to say either way. The data advises against it during both pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice if you're pregnant, planning to become pregnant, or nursing.
Does this really help with menopausal symptoms?
Royal jelly is possibly effective for menopausal symptoms based on the evidence we hold. That means there's some support for it, but it's not proven. Results vary, so realistic expectations matter.
What are the most common side effects?
In most people, royal jelly is well tolerated. Those who do have reactions typically experience itching, hives, eczema, or oral allergy syndrome. These are much more common in people with a history of asthma or allergies.
Will this help with hair loss?
We don't have enough reliable evidence to say whether royal jelly works for hair loss. The data on this is insufficient to rate it either way.
