Creatine may be one of the most misunderstood supplements in existence.
Many people still believe it’s a steroid.
Many people still believe it’s harmful to the kidneys.
Many people still believe children should never take it.
Yet creatine is one of the most extensively studied supplements in the scientific literature.
Studies involving children, adolescents, athletes, older adults, and various clinical populations have repeatedly shown benefits for strength, performance, lean mass, and physical function.
Importantly, studies lasting up to roughly 3 months have not demonstrated harm in these populations.
One of the most interesting parts of this discussion is that many people hear:
“We don’t have enough long-term data.”
And interpret that as:
“We have evidence that it’s dangerous.”
Those are not the same statement.
We often make recommendations based on physiology, mechanisms, shorter-term trials, observational evidence, and the totality of evidence available.
Long-term randomized trials in children are difficult to fund, difficult to maintain, and extraordinarily expensive.
In fact, one reason they may not exist is that many researchers already view creatine as relatively safe, reducing the urgency for massive long-term trials.
That doesn’t prove safety.
But neither does the absence of a 10-year trial prove danger.
I’d genuinely like to hear from physicians, researchers, dietitians, exercise physiologists, and strength coaches:
What evidence would change your mind?
