HelloPharmacist Scorecard of Royal Jelly "500" by Solgar

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 Sep 10, 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.

Solgar's Royal Jelly 500 contains one active ingredient: royal jelly concentrate, a nutrient-rich secretion produced by honeybees. The softgel capsule also holds several inactive ingredients—safflower oil, gelatin, yellow beeswax, soy lecithin, and glycerin—which are fillers and capsule materials that help deliver the active ingredient.

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 Royal Jelly's overall clinical evidence instead.

Moderate

Some clinical evidence supports Royal Jelly 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: Menopausal symptoms — rated "Possibly Effective" (Natural Medicines).

Royal jelly has been studied for several uses. The data suggests it may be possibly effective for menopausal symptoms.

For hay fever (allergic rhinitis), physical performance, and diabetes, the evidence points toward possibly ineffective. As for male-pattern baldness (androgenic alopecia), there isn't enough reliable evidence yet 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 by most people. The main concern is allergic reaction—it can trigger serious reactions in people with a history of asthma or atopy (a tendency toward allergic conditions).

Common symptoms in sensitive people include itching, hives, eczema, shortness of breath, and oral allergy syndrome. Rarely, it can cause anaphylaxis (a severe whole-body allergic reaction), status asthmaticus (severe asthma), or even death in those with asthma or atopy.

One case also reported bloody diarrhea and colon inflammation after taking royal jelly, which resolved after stopping it. The safety data for pregnancy and breastfeeding is not sufficient to recommend use—there isn't enough information to know whether it's safe either way.

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

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.

Before taking this product, double-check with your doctor or pharmacist if you take warfarin (or any blood thinner)—royal jelly may increase bleeding risk. Also check if you're on any blood pressure medications, since royal jelly might lower your pressure further.

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.

Royal jelly may appeal to you if you're looking for support with menopausal symptoms and you don't take blood pressure medications or warfarin. If you have asthma or a history of allergies, be extra cautious and start carefully.

Most importantly, check with your doctor or pharmacist before adding this to your routine, especially if you're on any prescription medications.
