The best PQQ. I've tried Doctor's Best and Jarrow, which look identical to each other and did not get any benefits. All 3 brands contain trademarked BioPQQ. This pill is bigger and with lighter colored contents, which might mean it has filler but it doesn't matter. It just works.
Really great for facilitating recovery from illness. It really increased energy levels to allow faster healing from flu for a loved one. Personally, I take it to increase stamina for times when a lot pf physical work is needed, like clearing the yard or when heavy lifting may be needed. It improves ones ability to handle stress and the effect is felt on the first capsule. If you are already on a healthy diet , PQQ can still add to your feeling of wellness and break new barriers for you. I will definitely be buying this again.
