Fascinating study, and thanks for posting it.
The study was for a group of 70-80 year olds vs. 21-30 year olds. I’m sure the gap these supplements fill is due to a progressively worse ability for us to produce for ourselves. So at what age would you suppose it is beneficial to start a regiment of GlyNAC? Would you wait to age-70 & start at the recommended dosage? Or start in your 60’s a lower dosage?
I’d say age issues begin around 40.
