L-Arginine
An amino acid that serves as the primary precursor for nitric oxide synthesis, with research studying its relationship to vascular tone and physical performance. See our L-Arginine article.
L-Citrulline DL-Malate
Converts to L-Arginine in the kidneys more efficiently than oral L-Arginine reaches systemic circulation, making it a more bioavailable route to support nitric oxide production. See our L-Citrulline guide.
Ginkgo Biloba

Horny Goat Weed
A botanical whose active compound, icariin, has been studied for its influence on vascular function and nitric oxide metabolism. More detail in our Horny Goat Weed guide.
