Is creatine worth taking if you strength train after 50?

Start strength training after 50 and you will soon come across creatine. It is one of the most researched supplements, but for a long time most of that research involved young athletes. So the question is whether it still adds anything later in life.

The short answer from recent meta-analyses is that, alongside strength training, creatine can add a little to strength gains. For muscle mass and everyday physical function the evidence in older adults is less certain. The effective part remains the training itself.

What research in people over 60 shows

In 2026, Yao and colleagues pooled eleven randomised trials in adults aged 60 and over. In every trial both groups did strength training; the difference was whether creatine was added. With creatine, strength gains were somewhat larger. The effect was small but statistically significant, and the certainty of the evidence was moderate.

For muscle mass and physical function the researchers found no statistically significant difference, with low and very low certainty of evidence respectively. Dose, a loading phase, study length and how often or how hard people trained did not explain the differences between studies. The authors state explicitly that their findings should not simply be applied to frail older adults, people with sarcopenia or those with functional limitations.

Women after menopause

A 2026 meta-analysis by Naddafha and colleagues looked at seven randomised, placebo-controlled trials with 608 postmenopausal women, with an average age of about 62. The trials lasted 12 to 104 weeks. Creatine produced on average 0.37 kg more lean mass and a 7.5 kg larger gain on the leg press.

Those benefits were seen when at least 5 grams of creatine a day was combined with strength training. Trials using 3 grams a day or less without strength training found no measurable effect. Bone density did not change overall. Side effects were mild and as common as with placebo, and kidney markers did not change. The researchers rated the risk of bias in most trials as raising some concerns.

Lean mass is everything in the body except fat, so it is not a direct measure of muscle.

And between 40 and 60?

There is less targeted research for this group. In 2024, Desai and colleagues analysed twelve studies in adults younger than 50. Creatine alongside strength training produced 1.14 kg more lean mass than training alone, and a body fat percentage 0.88 percentage points lower. Training experience made no difference.

In 2023, Burke and colleagues looked at ten studies that measured muscle growth directly with MRI, CT or ultrasound. The additional effect of creatine was small: 0.10 to 0.16 cm more muscle thickness, in both the upper and lower body. Younger adults appeared to benefit slightly more than older adults, but that difference was small.

If you are between 50 and 60, you fall between the groups that were studied. The direction is the same in every analysis, but these are always group averages and modest differences.

What this means in practice

The studies compared training with creatine against the same training without it. They show what creatine adds on top of training, not what it does instead of training. If you do not train regularly yet, that is where to start. Our article on how little strength training is enough explains how to start small.

Nutrition comes next. How much protein you eat across the day is a bigger question than when you eat it; we covered that in how much protein, and when. Creatine only becomes a question once that foundation is in place.

The doses in these studies are research doses, not personal advice. In the trials in postmenopausal women, benefits appeared from 5 grams a day combined with strength training. The analysis in adults under 50 mentions 7 grams, or 0.3 grams per kilogram of body weight, a day. All of the studies, with their limitations, are in our Evidence Library.

When to check first

Do you have a kidney condition, take medication or receive treatment for a chronic condition? Then talk to your doctor or pharmacist before you start taking a supplement. The fact that kidney markers did not change in the studies says something about the people in those studies, not about your situation.

Training first

Creatine is not a substitute for training and not a shortcut to more muscle. If you train consistently and eat well, you might consider it as a small addition. Whether that makes sense for you depends on your goal, your health and what you already do.
