Arginine, citrulline, beta-alanine and the nitric-oxide pathway — mechanisms, studied doses and the salt-form arithmetic.
The endothelium is the single-cell lining of every blood vessel, responsible for producing nitric oxide and regulating vessel tone. Its
Leafy greens and beetroot are rich in inorganic nitrate, which oral bacteria and the body convert into nitrite and then nitric oxide —
Beta-alanine is the rate-limiting precursor of carnosine, which buffers acidity inside muscle. Its research base concerns high-intensit
Citrulline raises plasma arginine more effectively than arginine itself, because it bypasses first-pass breakdown in the gut and liver
L-arginine is the direct substrate for nitric oxide, studied mainly for vascular function, blood pressure and exercise performance at i
Nitric oxide is a short-lived signalling molecule made from arginine that relaxes the smooth muscle lining blood vessels, widening them
