Emory scientists find oral tetrahydrobiopterin can reduce high blood pressure

...indings by Emory researchers suggesting that oral tetrahydrobiopterin ( also known as BH4) holds promise as a therapyfor patients with HTN. BH4 is an essential co-factor needed in the body for the synthesis of nitric oxide (NOS). "In its absence, the nitric oxide synthases become 'uncoupled', producing superoxide rath...
