Some, but not all, observational studies have found that elderly individuals with lower status of folate and/or vitamin B 12 may have poorer memory performance, especially episodic memory (i.e., memory of events, times, and places) (108-111)
Furthermore, the problems associated with vitamin C and E derivatives (e.g., limited tissue retention, targeting to the active site of oxidative stress, no targeting to specific ROS, and poor interaction with specific carriers) will largely also apply to these substances (especially because they structurally resemble vitamin C and E and share similar mechanisms of action)
Do not give FIRDAPSE to other people, even if they have the same symptoms that you have
