Folic acid is vital for humans and other animals as it is one of the basic building blocks and catalysts for several important biochemical reactions of the body.

Results. The study results indicate a 1.5-fold increase in COVID-19 diagnosis risk and a 2.5-fold increase in COVID-19-related mortality risk associated with folic acid supplement prescriptions.

Bacteria are more susceptible to antibiotics when they can't produce fatty acids, ... and that’s to serve as a co-factor in fatty acid synthesis,” says Brown.

HIV drug doluteglavir interferes with the binding of folate to its receptor, thus promoting neural tube defects. Folic acid supplementation can mitigate the risk of the medication in an animal model.
