Anonymous wrote:the preworkout variety is fine but should be used according to the instruction. They come in caffeinated or non. Its like a cup of coffee. If the user has a sensitivity to caffeine search for the non caffeinated. Also if your child already drinks coffee that should be reduced. I'm not saying these are loaded with caffeine but kids should be monitored..label says 1 scoop use just 1 not 2 or.... And my point about if they are already drinking coffee realize that this basically adds a cup to their total. It can impact sleep if taken at night but ymmv.
Ive used preworkout creatine for years there is plenty of info online. Just make sure they use it according to instruction. My kids started using it as well but possibly a little older than what yours are.. I think my son was 19. Adding protein to the diet also helps
You can get pre-workout formulas that include creatine, but those are mostly marketing hype - the only really prove ingredients in them are caffeine and creatine. You can buy caffeine pills and a tub of plain creatine for a lot cheaper.
