I would never take these again!!!
I've been taking these vitamins for the past couple years and at first they were working for me it gave me the energy I needed throughout the day because yes it does contain some type of caffeine that has time went on I started getting upset stomach couldn't sleep diarrhea a few times I thought I could take the vitamin without food or on my way to get my breakfast and it made me sick to my stomach very nauseous so I am completely discontinuing using this vitamin and I would not recommend it to anyone
