By Arun AgrahriLast reviewed
Short answer
Yes. Creatine is treated as safe for long-term daily use. It does not damage the kidneys; elevated creatinine on blood tests is a normal byproduct, not a sign of kidney trouble. Emerging safety data even covers children and pregnancy.
Creatine is worth taking.

Creatine is safe for long-term daily use and does not damage the kidneys. It is one of the most studied supplements in sports science, with hundreds of peer-reviewed studies over decades. Its safety profile is well established, and it is treated as safe for continuous daily use.
The most common worry, kidney damage, does not hold up. Creatine raises creatinine on standard blood tests, which can falsely flag kidney issues, because creatinine is a byproduct of creatine metabolism. Darren Candow, a creatine researcher and guest on Rhonda Patrick's show, calls that rise a false positive and says creatine does not harm kidney, liver or heart cells.
Layne Norton, a guest on Andrew Huberman's show, says the kidney and liver scares have been debunked and there is no evidence it harms a healthy kidney or liver. Peter Attia's clinic uses cystatin C instead of creatinine to check kidney function in people taking creatine.
The hair loss worry rests on one study that showed a slight rise in DHT and never measured hair. Candow and Norton both point out that it did not measure hair loss directly.
Candow also covers emerging safety data for vegans, who may gain most because they get less creatine from food, and for children and pregnancy.
The only common side effect is mild stomach discomfort at high doses (20g+ during loading phases). Sticking to the standard 5g/day dose without loading avoids it.
