Works Well (in medical ways) for me. Less costly than supplements.
I'm not a coffee drinker. These have a bit of caffeine, but it doesn't hurt my tum.  Unlike 'energy drinks' , which I'll never use, these have clean ingredients. After a different Virus (in '09) I rcvd the gift (aaargg ) of long term PVS (post viral syndrome.---now named 'long-haulers' ). Researched foods & supplements  for symptoms-aid  of PVS, ME/CFS and Lyme disease. Each have similar long-term similar symptoms. I came up w/a group of 5 that do help. My 2nd virologist agreed w/the nutrients and then mentioned "5 hour" (stating he was not sharing info in his position as a physician, but as a man whose spouse uses it for similar issue).  I rcv the same nutrients in one (1) bottle .Far less costly & more convenient than multiple jars of capsules. On midway days, I sip a 1/2 bottle on rising. Rougher days, a full. It remains part of my maintenance program when fatigue (& brain fog) have me knockered.
