The evidence in words
The verdict
For muscle (myostatin), Epicatechin earns evidence grade D (trivial effect, low consistency) — the evidence does not support the claim. Overstated
How it might work
It boosts nitric-oxide-mediated blood flow and mitochondrial biogenesis; the muscle claims rest on lowering myostatin / raising follistatin, seen mostly in small or animal studies.
How to use it
Safety & cautions
Very safe at food-relevant doses.
Bottom line
Solid for vascular/blood-flow benefits as a cocoa flavanol; the myostatin muscle hype is not established. Dark chocolate delivers it cheaply.
