Okay so since I have been working out and single I sort of live off supplements. From whey protein to other Amino acids, Glutamine, Creatine, multivitamins, etc. My health has been pretty good. Had a cold, toughed it out until I could get a Z-Pack (as usual doesn’t work until you have taken the last one) but in general all systems go. Being one of the rare hockey fans, one of the sponsoring products is Cold-FX. It touts to Strengthen the Immune System. The ingredients are suspect, but a little Ginseng never hurt anyone.
