What
moves it.

These biological pathways influence Systolic Blood Pressure. Click any to see what affects it.

established
NO
Nitric Oxide Production

NO dilates blood vessels, improving blood flow to muscles and brain.

established
cGMP
cGMP Pathway

cGMP drives smooth muscle relaxation and vasodilation.

supported
ACE
ACE Inhibition

ACE converts angiotensin I to angiotensin II, which raises blood pressure. Inhibiting it lowers BP.

What
affects it.

amino-acid
L-Citrulline

Raises blood arginine and nitric oxide more efficiently than arginine itself.

established$
amino-acid
L-Arginine

NO precursor. Poor oral bioavailability — citrulline is usually better.

supported$
amino-acid
Taurine

Supports cardiac function, bile acid conjugation, and neurotransmission.

supported$
mushroom
Cordyceps

Studied for exercise performance and oxygen utilization. Human data mixed.
