showed that IGF1 LR3 had about 100-fold lower affinity for IGFBP-3 compared to native IGF-1, while retaining similar receptor binding characteristics

Additionally, there was a tentative observation of increased epithelialization, which is the process deemed necessary for the regeneration of stratum cornuem, or outer most layer of the skin barrier, under these experimental conditions
Native IGF-1 has a plasma half-life of approximately 10-20 minutes because it binds insulin-like growth factor binding proteins (IGFBPs), particularly IGFBP-3, which clears it rapidly
Hence, this genetic polymorphism may explain differences in cysteine and methionine metabolism in LC patients
This is why most practitioners who recommend oral glutathione now favour liposomal forms over standard capsules
