Evidence notes
Preliminary human RCTs show modest benefits for endurance performance and blood flow parameters. Most studies small (n=20-40) and from Asian institutions. Limited long-term safety data. Effect sizes modest. Requires larger, independent replication.
Grade C: Mostly observational or small trials; mechanism is plausible but unproven at scale.
