This is the molecule almost nobody talks about. It's why your arginine, citrulline and beetroot did nothing.
ADMA is a molecule in your blood that blocks eNOS, the enzyme that makes your nitric oxide. Diabetic men run abnormally high on it.
So you can pour in all the arginine and beetroot you want. You have, and you felt exactly nothing. ADMA slams the gate shut downstream, and the fuel just pools behind it, going nowhere. The pill can't force it open either. It only guards the trickle you've got left.
This is where pine bark's OPCs earn their keep. They ease the blocker off eNOS, so your body can finally use the raw material it already has.
