Twenty years ago, I contracted glandular fever. Even though I became well again, nasty symptoms (weakened) regularly plague me every couple of weeks, a lasting result of the glandular fever. Every year after that, around autumn time I would feel tired and weak. This would last for about three months. As soon as the days became shorter, my energy was gone. Then I started taking Aronia: The lasting effects of the glandular fever were blown away. As soon as I stopped taking Aronia (as a test), the symptoms would return. So, I took the Aronia again and immediately I would feel better. I highly recommend Aronia to all those who have trouble getting back on track after a bout of Glandular fever!
