Are creatine supplements safe?

I am a 24-year-old male. I go to the gym 3 times a week and I want to start taking creatine supplements. Are creatine supplements safe?

They can be if used correctly, and it's a good, clean, reputable company with good reviews.
NO! Neither is it safe to have protein 3 meals a day. The body only processes the protein you eat when you are sleeping. The rest of the day the protein gets in the way. So eat fruit for breakfast, followed by fat an hour later, then carbohydrates, fat and veggies for lunch and finally, protein and veggies for dinner.
We are not really sure that protein supplements and creatine supplements are completely safe, especially the protein supplements. The reason is that the extra protein (and potentially also the creatine also) may force the kidneys to work harder than they should, resulting in kidney damage. The question is hard to answer, however. My recommendation is to do everything in moderation, and to go to the gym as the main way to get the kind of body that you would like.
I assume that you are 24 years old without any medical problems. If you have any underlying heart, liver or kidney disease creatine may not be safe to ingest. Generally, creatine is safe in small quantities and great if trying to build muscle mass. 2-3 g per day is recommended. Be careful not to combine with other drugs that are toxic to the kidneys such as alleve,
motrins, or ibuprofen. Also, do not take with excessive caffeine.
ABSOLUTELY NOT!!! The risk of damage to your kidneys from taking Creatine is so significant that I advise all of my patients to avoid the use of all Creatine containing products. Just say NO!

According to the latest UptoDate literature, "Although some have claimed that creatine can adversely affect kidney function, limited published evidence and wide experience with this supplement suggest that this is not true in patients with normal baseline renal function. The American College of Sports Medicine (ACSM) recommends it be used only by physically mature, well-developed athletes. For this reason, it is not recommended for adolescent athletes.
Of note, creatine is sold in a number of different forms other than the recommended creatine monohydrate supplement. These formulations include ethyl ester, nitrate, and phosphate, and are usually more expensive, may contain impurities, and may have no added ergogenic benefit."
