EDITIED TO ADD: Before taking Zinc get your Serum Zinc and RBC Zinc levels tested. Easy to do in the US if you have some money. Also get your Serum Copper and Ceruloplasmin tested since taking zinc at high dose for a while will lower copper since zinc creates Metallothioneins that capture the copper in the intestine before it can be absorbed. -- Hey, thanks for being curious! Science! Zinc and Tetrahydrobipoterin: https://pubmed.ncbi.nlm.nih.gov/31732151/ https://pubmed.ncbi.nlm.nih.gov/31732151/ The Gene GCH1 is central to making Tetrahydrobiopterin and uses zinc as a cofactor. https://www.uniprot.org/uniprotkb/P30793/entry https://www.uniprot.org/uniprotkb/P30793/entry The zinc coupling of NOS via GCH1: https://www.ahajournals.org/cms/asset/2cc8b7a0-a31a-4759-bc8d-da0d1f512dcf/7ff2.jpg https://www.ahajournals.org/cms/asset/2cc8b7a0-a31a-4759-bc8...
