Royal jelly

Bee-secreted glandular product traditionally used for vitality, modern evidence is small and mixed across multiple indications.

Why

Royal jelly is the protein-rich glandular secretion fed exclusively to queen bee larvae. Used in traditional and folk medicine for vitality, fertility and longevity. Modern RCT evidence is small and spread across multiple indications: lipid markers (Salehi 2020 meta-analysis), menopausal symptoms (Asama 2018), wound healing topical. No consistent strong signal in any single indication.

How it works

Major royal jelly proteins (MRJPs), 10-hydroxydecenoic acid (10-HDA, unique to royal jelly), and varied minor bioactives. Mild oestrogenic activity, antioxidant capacity, and proposed effects on insulin sensitivity documented preclinically.

Expected onset · Subjective effects within weeks; biomarker changes over 8–12 weeks

How to take

Dosage

Fresh royal jelly: 500–1,500 mg/day. Lyophilised: 300–1,000 mg/day.

Once daily, morning

On the label

Stated 10-HDA content as quality marker. Fresh (refrigerated) or lyophilised (room temperature). Bee-allergy patch-test before broad use.

Ideal for

Adults exploring bee-product supplements with realistic expectations; perimenopausal women open to gentle traditional options.

Bee-product allergy contraindicates, serious anaphylactic reactions reported including in those with no prior bee-venom allergy. Asthma: caution (rare bronchospasm reports). Pregnancy and breastfeeding data limited. Quality varies widely; refrigeration required for fresh product.

Evidence

At a glance

Salehi 2020 meta-analysis: royal jelly modestly reduced total cholesterol and LDL across RCTs. Asama 2018 RCT: royal jelly 800 mg/day for 12 weeks improved menopausal symptom scores vs placebo. Preliminary, RCTs exist in non-tier-1 journals but are small or short-duration. No Cochrane review, EMA monograph or EFSA-authorised claim covers the indication.

Limitations

Preliminary, RCTs exist in non-tier-1 journals but are small or short-duration. No Cochrane review, EMA monograph or EFSA-authorised claim covers the indication.
