Creatine is best known for its use in sports and fitness, but it is increasingly discussed in relation to healthy ageing, muscle function, and long-term wellbeing. In the UK, interest in creatine for longevity tends to focus on maintaining strength and function over time rather than performance enhancement.
Many people exploring longevity are less concerned with athletic goals and more interested in supporting mobility, independence, and resilience as they age.
This guide explains how creatine is commonly discussed in relation to longevity, what evidence exists, how it’s typically used, and what UK guidance says without exaggerated or anti-ageing claims.
Who this is for
This article is written for:
UK adults aged 40–70
People thinking about long-term muscle strength and physical function
Those interested in ageing well rather than sports performance
Readers looking for evidence-based, non-hyped information

What creatine does
Creatine is a naturally occurring compound found in small amounts in foods such as red meat and fish. It plays a role in energy production within muscle cells and contributes to normal muscle function.
In longevity discussions, creatine is commonly explored for:
supporting muscle mass and strength
helping maintain physical performance with age
complementing resistance exercise and adequate protein intake
Creatine is not intended to slow ageing itself. Instead, it is discussed as a supplement that may help support physical function over time when used appropriately.
Why people look into creatine for longevity
Many people begin exploring creatine later in life when they notice changes in strength, recovery, or muscle mass. Rather than aiming for performance gains, the focus is often on maintaining normal function and staying active for longer.
Creatine is usually considered alongside lifestyle factors such as regular movement, resistance training, and sufficient dietary protein.
Evidence overview (NHS / EFSA / PubMed)
NHS overview
The NHS notes that creatine is naturally present in the body and obtained through diet. The NHS generally emphasises meeting nutritional needs through food and cautions that supplements are not necessary for most people, though some may choose to use them in specific contexts.

EFSA overview
The European Food Safety Authority (EFSA) has authorised a health claim for creatine relating to improved physical performance during short-term, high-intensity exercise, at a daily intake of 3 g. EFSA does not authorise claims relating to longevity or ageing.

Research context (high level)
Research has examined creatine supplementation in older adults, often alongside resistance training, with outcomes related to muscle mass, strength, and physical performance. Results vary, and benefits are generally discussed in the context of supporting function rather than extending lifespan.

Frequently Asked Questions
Is creatine good for longevity?
Creatine is not proven to extend lifespan. It is commonly discussed in relation to maintaining muscle strength and physical function, which are important factors in healthy ageing.
Can older adults take creatine?
Some older adults use creatine, often alongside resistance exercise. Suitability depends on individual health and should be discussed with a healthcare professional where appropriate.
Do you need to load creatine?
Loading phases are not necessary. Many people use a steady daily dose of 3–5 g.
Is creatine safe for long-term use?
Creatine has been studied extensively, but long-term use should always follow recommended dosages and consider individual health factors.
Final thoughts
Creatine is increasingly discussed in longevity contexts because of its role in muscle function and physical performance, not because it slows ageing itself. For some people, it may be a useful addition to a broader routine focused on movement, nutrition, and consistency over time.
Understanding realistic expectations and UK guidance is key to deciding whether creatine fits your approach to healthy ageing.
