Copper Chelation and Delivery At the most fundamental level, GHK functions as a copper chelator and delivery system - the tripeptide binds Cu with exceptionally high affinity (binding constant approximately 10 M, among the highest known for biological copper chelators), forming a square planar coordination complex where the copper ion is coordinated by the nitrogen atoms of the terminal amino group, the two peptide bonds, and the imidazole nitrogen of histidine
Methylcobalamin supports the bodys methylation pathways, which play a key role in energy production, neurological balance, and red blood cell formation
However, because it influences metabolic pathways, its essential to approach its use cautiously
