Royal Jelly: Defined by 10-HDA and Its Proteins

Royal jelly is the milky secretion worker bees produce to feed the queen. What defines it, beyond the lore, is its chemistry: a specific fatty acid called 10-HDA and a set of major royal jelly proteins. Those are the markers that tell you you're looking at the real thing.

What it is

Royal jelly is a secretion from the glands of worker bees, made up of water, proteins, sugars, lipids, vitamins, and minerals. Its signature components are 10-hydroxy-2-decenoic acid (10-HDA), found almost nowhere else in nature, and the major royal jelly proteins (MRJPs).

How it works

Royal jelly is a nutrient-dense, compositional ingredient rather than a single isolated active. In the lab, its antioxidant activity is among the most consistently documented properties, attributed to its proteins, peptides, fatty acids, and phenolic compounds. The honest framing is nutritional and compositional.

Why the form & source matter

Because 10-HDA is essentially unique to royal jelly, it's used as a quality marker — a way to tell genuine, well-handled royal jelly from something diluted. That's the one technical detail worth knowing: with royal jelly, the marker compound is how you compare.

How Monthlees uses it

Monthlees includes royal jelly in its hive blends — the Bee Bread (with royal jelly, propolis and vitamin C) formula and Bee Pearl with Vitamin C — combining it with the other apian ingredients and a defined amount of vitamin C.
