Creatine isn’t just for adults. I give my son 2.5 g/day. There are (albeit few) studies in kids and adolescents showing creatine can improve performance. For example, trials in adolescent soccer and basketball players report improvements in power, jumping, sprint/anaerobic performance, and technical skills with creatine (often using ~0.03–0.1 g/kg/day). I’m also interested in its potential brain/energy effects. The key is dose. You don’t want to use adult-loading amounts, but 2.5 g/day (maybe slightly above) is a conservative, reasonable range. On busy days, I’ll also use protein powder in a smoothie to fill protein gaps. One thing I look for is avoiding certain emulsifiers, which can be rough on the gut for some people when used frequently. I covered this in a recent member Q&A. You can watch it here -
