If you've looked at nitric-oxide supplements before, you've probably seen both L-arginine and L-citrulline listed. They're related, but not identical — and MemoHoney includes both on purpose.
L-arginine is a direct precursor to nitric oxide, meaning your body can convert it fairly directly. It's one of the most widely studied amino acids for circulation support.
L-citrulline works differently — your body converts it into arginine first, which some research suggests can lead to more sustained arginine levels over time compared to taking arginine alone.
By combining direct and indirect nitric-oxide pathways — four sources in total — MemoHoney is built to support circulation from multiple angles rather than relying on just one amino acid to do all the work.
