Royal jelly

Also known as: bee royal jelly

Royal jelly is a nutritious secretion produced by worker bees to feed the queen; it contains protein, sugars, the fatty acid 10-HDA and B vitamins. It is sold for energy and immunity, but good human evidence is limited.

What it is used for

  • easing menopausal symptoms – weak evidence from small studies
  • energy and immune support – weak evidence
  • effect on cholesterol levels – weak evidence

Forms and how they differ

fresh royal jelly

keep refrigerated, short shelf life

freeze-dried in capsules

more stable; look for the stated 10-HDA content

blends with honey

royal jelly content is often low

When to take it

In the morning on an empty stomach or as on the label; let fresh royal jelly dissolve under the tongue.

Pairs well with

A varied diet and enough sleep; possibly bee pollen or propolis if you tolerate them.

Do not combine / separate

Do not combine with warfarin without asking your doctor – interactions have been reported.

Watch out for

Do not use if you are allergic to bee products or pollen, or have asthma – serious allergic reactions including anaphylaxis can occur. During pregnancy and breastfeeding, or if you take blood thinners, blood-pressure or other medicines, consult your doctor.

Safety

Do not exceed the label dose; on first use start with a small amount and watch for reactions.

Practical tip

If you have ever reacted to honey, pollen or a bee sting, it is better not to try royal jelly.
