What is Beta-Ecdysterone (20-Hydroxyecdysone)?

Beta-Ecdysterone, also called 20-Hydroxyecdysone, is a naturally occurring ecdysteroid found in some plants and insects. It is sold as a sports nutrition supplement for potential training-related benefits.

What is a typical Beta-Ecdysterone dosage?

Supplement doses commonly fall in the range of about 50–500 mg per day. Product potency and formulations vary, so follow label directions and consider professional guidance.

Is Beta-Ecdysterone safe?

Human safety data are limited compared with many established supplements. People who are pregnant or breastfeeding, have medical conditions, or take medications should consult a clinician before use.

Will Beta-Ecdysterone improve exercise performance?

Evidence suggests possible modest improvements in certain performance measures, but findings are not consistent. Training quality, diet, and recovery remain the primary drivers of performance changes.

Mixed

Note on evidence

Early human clinical trials and animal studies suggest anabolic-like effects, but data are limited and inconsistent. Larger, long-term human studies are needed to confirm safety and efficacy.

May support muscle growth and strength

Mixed

Randomized controlled trials suggest beta-ecdysterone may increase muscle hypertrophy and strength when combined with resistance training.
