Creatine after 50: what the evidence and the regulator actually allow
Creatine is one of very few supplements with an authorised health claim behind it, and one of the few where the evidence in older adults is specifically recognised. Here is the permitted wording, the dose it applies at, and the condition attached to it that most articles leave out.

Most supplements are sold on inference. Creatine is unusual: it is one of a small number where regulators have looked at the evidence and authorised specific wording. That makes it a useful case study in reading claims properly, as well as a reasonable thing to consider if you train.
The claim that most people know
The long-standing authorised claim is that creatine increases physical performance in successive bursts of short-term, high intensity exercise. It applies at a daily intake of 3 grams.
Note the precision. Successive bursts. Short-term. High intensity. That is sprinting, lifting, and interval work, not endurance, and not general wellbeing. The wording is narrow because the evidence is narrow, and a brand stretching it beyond that is stretching it beyond what was authorised.
The claim that matters if you are over 50
This is the one usually missed.
In 2016 EFSA issued a positive scientific opinion on a further claim: that daily creatine consumption can enhance the effect of resistance training on muscle strength in adults over the age of 55.
Read the conditions attached to it, because they are the whole point:
- At least 3 grams of creatine a day
- Combined with regular resistance training of moderate intensity
- Specified as roughly three sessions a week, sustained over several weeks
Creatine on its own is not what was assessed. Creatine plus resistance training is. The supplement is the amplifier; the training is the signal. Taking it without training the muscles is paying for the amplifier and never plugging in the guitar.
Given that a study of 253,423 English adults found only 7.3% of men and 4.1% of women meet the UK strengthening guidelines, and that 50 to 64 year olds are 45% less likely to meet them than 19 to 34 year olds, the training half is where most people’s gap actually is.
Practical points
- Form: creatine monohydrate is the form used in the overwhelming majority of the research. The more expensive forms are not better supported.
- Dose: 3 to 5 grams daily. The “loading phase” you see described is optional; it reaches saturation faster, not higher.
- Timing: daily consistency matters, time of day does not particularly.
- Water: creatine draws water into muscle cells. Some people see a small increase on the scales in the first fortnight. That is water, not fat, and it is not a reason to stop.
- What it is not: creatine is not a steroid and not a stimulant. It is a compound already found in red meat and fish, and made by the body.
How to judge a creatine product
Because there are authorised claims here, the label is a genuine test of the brand.
A product using the permitted wording, stating the 3 gram threshold and naming monohydrate, is being straight with you. A product promising it will boost your energy, improve recovery or fix your fatigue has left the authorised wording behind, and in Great Britain, health claims must appear on the GB Nutrition and Health Claims Register and be used in wording that does not strengthen them.
You can judge a lot of a supplement company by whether they were willing to be boring where the rules require it.
