Royal Jelly
Contains unique 10-HDA fatty acid and royalactin — supports skin health, cholesterol, blood sugar, and menopausal symptoms.
What the evidence says
Royal Jelly helped in about half (4/6) of the studies that measured an effect — promising, but not unanimous.
Most evidence is from high-quality meta-analyses and randomised trials published 2007–2026 with a typical study size of 72 participants.

By outcome
Royal Jelly has an evidence score of 7.5/10 — strong evidence based on 34 indexed studies, including 3 meta-analyses. Contains unique 10-HDA fatty acid and royalactin — supports skin health, cholesterol, blood sugar, and menopausal symptoms.
The commonly studied dose of Royal Jelly is 300-3000mg daily. Research points to an estimated optimal dose around 3000mg, with a minimum effective dose near 1000mg. Individual response varies — start low and adjust.
The best time to take Royal Jelly is in the morning. Taking it with food is preferred. Royal jelly contains 10-HDA (10-hydroxy-2-decenoic acid), royalactin, and various bioactive peptides.
Astaxanthin
Mostly mechanism / observationalCarotenoid from algae that spans cell membranes for full-spectrum protection — studied for skin, eye health, and exercise recovery.
Soy Isoflavones
Likely helpsPlant compounds with weak estrogenic effects that support menopausal symptoms, bone health, and cardiovascular function.

Royal jelly is a milky secretion produced by worker bees to feed the queen bee, who lives 40 times longer than regular bees. It contains proteins, B vitamins, fatty acids (including unique 10-HDA), and royalactin. Research shows potential benefits for skin health, cholesterol, blood sugar, menopausal symptoms, and cognitive function. Its effects on bee longevity have made it popular as an anti-aging supplement.

Fresh must be refrigerated. Freeze-dried maintains potency. Look for standardized 10-HDA content (typically 5-6%).
Minimum: 4 weeks
Optimal: 12 weeks
Cycling: 8-12 weeks on, 4 weeks off
Note: Fresh royal jelly should be kept refrigerated. Lyophilized (freeze-dried) forms are more shelf-stable.
Meta-analysis found mixed results for lipid effects. One small RCT (n=7) showed modest cholesterol improvements but no HDL/triglyceride changes. Effects appear modest and inconsistent across studies.
Improved energy and reduced fatigue
Better skin hydration and appearance
Modest improvements in lipid profile
Can cause allergic reactions
AVOID - risk of anaphylaxis
May have mild anticoagulant effects — may affect platelet aggregation or vitamin K-dependent clotting factors, altering anticoagulant efficacy
Tip: Start with small dose; avoid if bee allergy; have epinephrine available if history of anaphylaxis
Tip: Take with food
Royal Jelly is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are allergic reaction, GI upset. Use caution if any of these apply to you: Bee product allergy; Asthma (increased risk of reaction); Atopic dermatitis.
Quercetin
Likely helpsFlavonoid with senolytic and anti-inflammatory properties — supports immune defense, allergy relief, and exercise performance.
