Longevity is often discussed in terms of supporting health, mobility, and independence over time, rather than preventing ageing altogether. In the UK, guidance generally focuses on balanced nutrition, consistent habits, and cautious use of supplements where appropriate.
Many people explore longevity-related supplements as part of a broader approach to wellbeing not as quick fixes, but as tools that may help support normal bodily function as they age.
This guide looks at the supplements most commonly discussed in relation to longevity in the UK, what they’re typically used for, what evidence exists, and what NHS and EFSA guidance says without exaggerated or anti-ageing claims.
Who this is for
This article is written for:
UK adults aged 35–70
People interested in supporting health as they age
Those looking to complement a balanced diet and healthy lifestyle
Readers who want clear, evidence-based information, not anti-ageing promises

What longevity supplements do (neutral explanation)
Longevity supplements are commonly discussed in relation to:
maintaining normal physiological function over time
supporting bones, muscles, and joints
contributing to normal energy metabolism
complementing diet and lifestyle habits
They are not intended to prevent ageing or disease. Instead, they are typically explored as part of a long-term, moderate approach to wellbeing.
People often explore supplements like this when they want to support their routine more consistently over time. It’s usually part of a wider approach that includes diet, sleep habits, and lifestyle changes rather than a standalone solution.
Evidence overview (NHS / EFSA / PubMed)
NHS overview
The NHS states that most vitamins and minerals should be obtained from a varied, balanced diet. Supplements may be useful in certain circumstances, but they are not a substitute for healthy eating or lifestyle habits.

EFSA overview
The European Food Safety Authority (EFSA) evaluates evidence for nutrient safety and health claims. EFSA has authorised specific claims for certain nutrients (such as vitamin D and omega-3 fatty acids) while rejecting many broader longevity or anti-ageing claims due to insufficient evidence.
