I'm a 24 year old man, healthy, and have been taking a preworkout formula that contains creatine. it's been working great, however i just want to confirm it's safe? i drink plenty of water, take the minimum amount, and occasionally have alcohol

I'm pleased that you: are concerned about the safety of supplements. As you know, creatine turns into creatine phosphate in the body and helps make ATP, a energy source for muscles. Evidence of its effectiveness is mixed: may help for short period of athletic activity; not for endurance. As with all supplements, their manufacture is not regulated. Most people can take with no problem; caution especially if kidney probs

Creatine daily: Creatine should be used only for people doing exercise in a regular basis to obtain energy for the new muscle mass, avoid it if you suffer from asthma or have history of kidney or liver dysfunction, 3gr daily is fine
