Nucleotides (adenosine, guanosine, cytidine, uridine, inosine monophosphates) are the building blocks of DNA/RNA.
Added to infant formula because breast milk contains 2-5% nucleotides.
In adults: 500-1,000mg/day improved immune function (increased NK cell activity) and gut mucosal recovery post-illness.
Traditionally considered non-essential (body synthesizes them) but now considered conditionally essential during: rapid growth, immune challenge, gut injury, and intense exercise.
