text: has anyone taken creatine as a teenager? can u tell me 'bout it ? i was wondering if anyone has taken creatine supplements as a teenager, im 16 and wondering.  since it hasnt been too researched i was wondering if anyone had some experiences to share. bunch of people took it in high school football i knew. i was in soccer so i didnt need it but i know it makes your muscles just look bigger by making the protien absorb more water. it's been shown in studies if you take it your more likely to get hurt in physical activities. the long term effects of the product are still unknown. take at your own risk.
