I am beginning to suspect the same, after experiencing severe headaches that may be attributed to homemade Liposomal C.
If only there was more definitive information regarding the efficacy of this production, or any explanation of the headaches that ensue. [yes, I do use non-gmo sunflower lecithin]
Seriously, you make an interesting case! I'm considering buying some legitimate Lipo-C from a manufacturer and comparing the results/symptoms.
