I had a 500ml energy drink before my workout this morning, no food. Sugar-free "Mother" 500ml for 23 calories, 160mg caffeine /260mg sodium. I had one of the best work outs Ive ever had today. Not sure if placebo effect or it actually helped. I noticed I didn't even need to take a sip of water from my water-bottle I take with me. Something tells me I'd prefer the energy drink over taking a caffeine pill, considering it's 500mls and tastes nice. The caffeine pills I have are 200mg but it's pretty boring to take that when I could be having a nice tasting energy drink. People keep telling me the energy drinks are no good/avoid at all costs. Wondering if this is just broscientist theories or if there's any truth to it. How can caffeine pills be okay but an energy drink with less mg of caffeine not be? I don't drink coffee or tea, so I'm not getting caffeine from any other source besides make coke zero, but I don't drink much of that and in-fact I don't think it even contains caffeine.
