Current interest in this peptide is linked to its multi-receptor activity and how it may influence signalling pathways associated with energy balance
[6] If this happens, vitamin B 12 deficiency may result in sense loss, loss of sensation in the feet, difficulty walking, poor balance, blurred vision, changes in reflexes, muscle weakness, decreased smell and taste, decreased level of consciousness, mood changes, memory loss, depression, irritability, clumsiness, disorientation, dementia and, in severe cases, psychosis
Zero-order kinetics are a dosing nightmare
You can see an example of a patient with leptin resistance and her labs below: In this result, her fasting leptin level is 48.2 (note that there is no reference range for leptin levels)
