Creatine is best known as a sports supplement, but it has also attracted interest from adults looking to maintain muscle strength, physical performance and independence as they age. These factors are important to healthy ageing, particularly when combined with regular resistance exercise and adequate protein intake.
Optimum Nutrition Micronised Creatine Monohydrate Powder is a creatine supplement designed to provide creatine in a convenient powder format. Its micronised formulation is intended to make the powder easier to mix, while creatine monohydrate remains one of the most extensively studied forms of creatine.
But is it worth considering as part of a longevity-focused routine? This review looks at the product, the evidence for creatine and healthy ageing, dosage, safety, and what to compare before buying.

This article is for general educational purposes only. Creatine is not a proven treatment for ageing or a supplement established to extend human lifespan.
What creatine does
Creatine is a naturally occurring compound found mainly in muscle tissue. The body produces some creatine, and dietary sources include foods such as meat and fish.
Inside muscle cells, creatine helps support the rapid regeneration of ATP, a molecule used to provide energy during short, intense activities.
Creatine supplementation has been studied extensively in relation to:
High-intensity exercise performance
Strength training
Muscle mass when combined with resistance exercise
Training capacity
Physical function
These effects are relevant to healthy ageing because maintaining muscle strength and physical capability can help adults remain active and independent.
However, supporting muscle and exercise performance is not the same as slowing biological ageing. Research into creatine’s possible cognitive and other longevity-related effects is ongoing, and claims of lifespan extension in humans are not established.

What does “micronised” mean?
Micronisation refers to reducing the particle size of a powder. In creatine products, this can help the powder disperse when mixed with liquid.
It does not mean that micronised creatine has been proven to deliver greater longevity benefits or necessarily produce better results than standard creatine monohydrate.
The more important considerations are the actual creatine dose, product quality, consistency of use and your exercise routine.
Creatine and healthy ageing: what does the evidence say?
Creatine is one of the better-studied sports supplements, particularly for exercise performance. Its relevance to healthy ageing is mainly connected to maintaining muscle and supporting resistance-training outcomes.
1. Muscle strength and physical performance
Creatine supplementation can improve performance in repeated, short-duration, high-intensity activities. Research also suggests that creatine combined with resistance training can improve strength and lean mass compared with resistance training alone in some populations.
For older adults, this is an important area of interest because muscle strength and physical function are relevant to mobility and independence.
However, creatine does not replace exercise. The evidence is most useful when considered alongside an appropriate training programme.
2. Muscle maintenance with age
Muscle mass and strength can decline with age, particularly when physical activity and resistance training are insufficient.
Creatine may help support training adaptations when combined with resistance exercise. It should be viewed as a potential addition to a broader strategy that includes adequate protein, regular activity and recovery.
3. Brain health and cognition
Creatine has also been studied for possible effects on cognitive performance, including in situations involving sleep deprivation, ageing or lower dietary creatine intake.
Results vary, and evidence is not strong enough to describe creatine as a proven treatment for memory loss, dementia or age-related cognitive decline.
4. Longevity and lifespan
Creatine is often discussed in longevity communities, but there is currently insufficient evidence to conclude that supplementation extends human lifespan or reverses biological ageing.
The more defensible reason to consider creatine is its established relationship with exercise performance and its potential to support strength-training outcomes.
How much creatine should you take?
A commonly used maintenance amount for adults who choose to supplement is 3–5 g of creatine monohydrate per day. The appropriate approach depends on individual circumstances and the product instructions.
A loading phase is not essential. Some protocols use a short loading phase followed by a lower maintenance amount, but taking a smaller daily amount can also increase muscle creatine stores gradually.
For a straightforward routine, consistency matters more than complicated timing.
A practical approach
Check the serving size on the product label.
Measure the powder rather than estimating by eye.
Follow the manufacturer’s instructions.
Take it consistently if you choose to use it.
Combine it with suitable resistance exercise for muscle-related goals.
Creatine does not need to be taken immediately before or after a workout to be useful. Choose a time that fits your routine.

Dosage & safety (UK)
Creatine monohydrate is commonly used in maintenance amounts of 3–5 g per day by adults who choose to supplement. This is general information rather than a personalised recommendation.
Keep the following in mind:
Follow the product label and avoid unnecessary high doses.
A loading phase is optional, not essential.
Maintain adequate hydration, particularly when exercising.
Temporary increases in body weight can occur as muscle water content increases.
Digestive discomfort can occur, especially with large servings.
Creatine can affect blood creatinine measurements, so tell your healthcare professional if you use it before having blood tests.
People with kidney disease or other significant medical conditions, those who are pregnant or breastfeeding, and anyone taking medication that may affect kidney function should seek advice from a qualified healthcare professional before using creatine.
Do not use creatine as a replacement for medical care, a balanced diet or a suitable exercise programme.
