Can You Take NADH with Threonine?

Taking NADH and Threonine together does not appear to cause any significant interactions. Research on L-threonine dehydrogenase, an enzyme involved in threonine metabolism, shows that it uses NAD+ to produce NADH, but there's no direct evidence of interaction between supplemental NADH and threonine. The body seems to handle them independently. The enzyme L-threonine dehydrogenase catalyzes the conversion of L-threonine to 2-amino-3-oxobutyrate, using NAD+ as a cofactor and producing NADH in the process. No direct biochemical interaction was reported between NADH and threonine that would affect their individual functions or metabolism.
