Folic Acid - The hidden link?

I’ve previously noticed when I eat certain foods avocados, asparagus and eggs my member performs better. I realized the main common link between those foods is folic acid. After going further down the research rabbit hole it appears that research was done and proven to help ED after months of use. https://pubmed.ncbi.nlm.nih.gov/31237081/

Has anyone tried supplementing with FA?
