What Are Royal Jelly and 10-HDA?
Royal jelly is a highly nutritious substance produced by worker bees to feed the queen bee and larvae. The queen bee, which feeds exclusively on royal jelly, can live up to 40 times longer than worker bees, demonstrating the incredible potential of this natural ingredient for health and longevity. Royal jelly is a milk-like substance rich in essential nutrients, including proteins, vitamins (especially B-complex), minerals, and unique fatty acids. Among its many components, 10-HDA (10-Hydroxy-2-Decenoic Acid) stands out as the most remarkable. This fatty acid is found almost exclusively in royal jelly and is considered a key marker of its authenticity and quality.
10-HDA is known for its antibacterial, anti-inflammatory, and most notably, cell regenerating properties. This is the key reason why queen bees can live up to 40 times longer than ordinary bees. On average, 10-HDA makes up about 3–6% of fresh royal jelly (on a dry weight basis).
Who Produces Royal Jelly
The process of royal jelly production by bees is a fascinating and complex natural mechanism. This substance is produced by young worker bees to nourish both bee larvae and the queen bee. Worker bees aged 5–15 days can produce royal jelly because they have two special glands in their heads:
- Hypopharyngeal glands → produce proteins and enzymes
- Mandibular glands → produce lipid and fatty acid components
The combined secretions from these two glands form royal jelly.
Worker bees create royal jelly using:
- Nectar and honey → as carbohydrate sources
- Pollen → as sources of protein, fats, vitamins, and minerals
- Water and bee enzymes → to aid in the synthesis of bioactive compounds
Inside the bee’s body, these nutrients are processed and secreted as royal jelly.
Production Process Inside the Hive
The queen bee lays eggs in the cells of the honeycomb. When the eggs hatch into larvae, worker bees feed all larvae with royal jelly for the first three days. Only the larvae chosen to become queens continue to receive royal jelly throughout their development.
As a result:
- Ordinary larvae → become worker bees
- Larvae continuously fed with royal jelly → develop into queen bees
Nutritional Effects of Royal Jelly on the Queen Bee
When bee larvae consume royal jelly, their growth is dramatically accelerated, they grow three times larger than worker bees, live much longer (5–6 years vs 45 days), and have extraordinary reproductive capacity (up to 2,000 eggs per day).
These remarkable effects are attributed to the bioactive components of royal jelly, such as:
- 10-HDA (10-Hydroxy-2-Decenoic Acid)
- MRJPs (Major Royal Jelly Proteins)
- B-complex vitamins and amino acids

10-HDA (10-Hydroxy-2-Decenoic Acid)
In the world of natural health and beauty, Royal Jelly has long been celebrated as the miraculous “Queen Bee’s food”. This nutrient-rich substance produced by worker bees is the sole nourishment of the queen bee, enabling her to live much longer and be far more fertile than ordinary bees. The secret behind its extraordinary benefits comes from a unique compound called 10-HDA (10-Hydroxy-2-Decenoic Acid).
Recent research reveals that one of the greatest benefits of 10-HDA is its ability to activate collagen production in the body. But what does that mean for youthful skin and overall health? Let’s explore this in more detail.
Why Is Collagen So Important for the Body?
Before going further, we need to understand the role of collagen. Collagen is the most abundant protein in the human body, accounting for about 30% of total protein. It acts as the “glue” that holds the body together, providing structure, firmness, and elasticity to:
- Skin: Maintains elasticity and moisture, prevents wrinkles
- Joints and Bones: Lubricates joints and strengthens bones
- Hair and Nails: Promotes strength and growth
- Internal Organs: Supports the structure of blood vessels and organs
Unfortunately, the body’s natural collagen production begins to decline by 1–2% per year after the age of 25. Factors such as UV exposure, pollution, poor diet, and stress further accelerate collagen breakdown, leading to sagging skin, fine lines, wrinkles, and joint pain.
How Does 10-HDA in Royal Jelly Activate Collagen Production?
10-HDA is not collagen itself, but rather a powerful activator that stimulates the body to produce its own collagen more effectively. Here’s how it works:
- Stimulates Fibroblasts:
Fibroblasts are cells in the dermal layer of the skin responsible for producing collagen, elastin, and hyaluronic acid. In vitro studies show that 10-HDA can stimulate the activity and proliferation of fibroblast cells, naturally increasing collagen production. - Fights Oxidative Stress:
Oxidative stress caused by free radicals is a major culprit behind collagen degradation. 10-HDA has strong antioxidant properties, helping neutralize these free radicals. By protecting cells from damage, it keeps fibroblasts healthy and functioning optimally. - Anti-Inflammatory Properties:
Low-grade chronic inflammation can damage existing collagen. The anti-inflammatory effects of 10-HDA create a healthier environment for skin cells, allowing newly produced collagen to last longer and resist breakdown.
In other words, consuming Royal Jelly rich in 10-HDA sends a “signal” to your body to restart its natural collagen production more efficiently.
Direct Benefits for Skin and Health
As collagen production increases, you can enjoy benefits such as:
- Firmer and More Elastic Skin: Reduces fine lines and wrinkles
- Improved Skin Hydration: Collagen works synergistically with hyaluronic acid to lock in moisture
- Faster Wound Healing: Accelerated cell regeneration helps repair damaged skin tissue
- Better Joint Health: Enhanced collagen helps lubricate joints and reduce pain
- Stronger Hair and Nails: Promotes healthier and more resilient growth
