Highly recommend it My husband hates coffee and is trying to get off all the sugary drinks but needs caffeine. Kaffn8 is the perfect solution! He uses water enhancers, adds Kaffn8 and its a dream come true. He loves the ability to vary the amount of Kaffn8 according to his needs. Tysm!! Also, the company was quick to ship the product and added a personal "thank you" note. Well done Kaffn8 👏

I got a brain injury kaffn8 helps symptoms I got a brain injury permanent brain damage, reactive gliosis as a result of this concussion so I suffer with headaches daily, and cognitive issues so I was given Ritalin, but I don't like Ritalin, so I began looking for jolt energy cola for caffeine but jolt is no longer for sale and searched for caffeine and found kaffn8 and I put it in my coca cola and it taste like jolt cola and get the caffeine I need. I no longer need Ritalin thanks to kaffn8,. Please don't stop selling this product. Because of your product kaffn8, it allows for a natural healthier way to deal with post tbi concussion syndrome symptoms instead of Ritalin a narcotic
