RE:Great article on PQQ ingredient in CELLF This stuff works!
In regards to improving brain function, while PQQ is somewhat effective on its own, when it is combined with a related compound well-known to all – coenzyme Q10 – even better results have been shown. This synergistic effect was first seen in animal studies and further demonstrated in a human double-blind, placebo-controlled clinical trial conducted in Japan in 2007.19 In this study of 71 middle-aged and elderly people aged between 40-70, supplementation with 20 mg per day of PQQ resulted in improvements on tests of higher cognitive function compared to the placebo group, but in the group receiving 20 mg of PQQ along with 300 mg of CoQ10 the results were even more dramatic. PQQ and CoQ10 are both involved in mitochondrial energy production, so these results are not that surprising.
