Can a 14 year old boy use creatine XXL ?


Thanks for the question. The answer about using CreatineXXL at age 14 (now called ExtremeCreatineXXXL) is that only with a parent's permission once they know all the details, then it's okay since creatine and the other components (glutamine and beta-alanine) are safe with the studied adult populations and probably safe for younger athletes (studies are not done with youth or pregnancy populations for ethical reasons).

That said, we always advise a more simple supplement program for young athletes as shown below. Once they achieve the “next level” in sports, they can now go to the next supplementation level.

Below is where we start all youth athletes and we progress them to the next level (strength and performance gains) if they continue to want to play at a high level. Once they reach D1 and/or the professional level of sports, more advanced programming is used These levels, which are not only healthy for all, are also needed to speed recovery from intense training bouts and help to maintain health and prevent injury.
