I also started MegaSpore biotic and SPM active so I'm not sure which one is doing what. I can say for certain that my cognitive function has improved. I am usually a quiet person and I find myself conversing and being able to recall things more easily. My job has a high cognitive demand and at 69 I really appreciate the strengthening effect. Nothing else was changed. I already take many nutriceuticals and nootropics so I am certain that these products were the cause of my positive changes. The changes were quick in onset, perhaps a few days, and continue to build. I am looking forward to a stronger immune system this winter as well.
