Beta-ecdysterone, a naturally occurring steroid-like compound primarily found in arthropods and plants like Cyanotis arachnoidea (blue dew grass), exhibits several notable biological effects.

Its key functions include:

1. Promoting Protein Synthesis‌: It stimulates protein synthesis in tissues, supporting muscle growth and repair mechanisms.

2. Regulating Metabolism‌: Beta-ecdysterone helps lower cholesterol and blood lipid levels, while also inhibiting abnormal rises in blood glucose.

3. Enhancing Bone Development‌: Studies in animal models indicate it can increase peak bone mass, suggesting potential benefits for bone health and osteoporosis prevention.

4. Mediating Molting & Development‌: Originally identified in insects, it triggers molting and metamorphosis, a role exploited in sericulture and aquaculture to synchronize development.

Beyond physiological effects, it finds applications in:

1. Agriculture‌: Used as a growth regulator in silkworm rearing and crustacean farming.

2. Medicine‌: Historically explored for treating arthritis and studied for its metabolic regulation potential.

3. Cosmetics‌: Incorporated as a specialized additive.

4. Pesticides‌: Under investigation as a third-generation insect growth regulator.

5. Supplements‌: Marketed for its purported anabolic and adaptogenic properties.
