Quick Answer: As we age, the immune system gradually becomes slower to respond and less efficient — a process researchers call immunosenescence. This doesn't mean decline is inevitable or unmanageable; diet, movement, sleep and targeted nutrition all play a role in supporting immune health as you get older.

What Is Immunosenescence?
Immunosenescence refers to the gradual, natural remodelling of the immune system that happens with age. It's not a single event but a slow shift — the immune system doesn't stop working, but it becomes somewhat less responsive and less efficient at recognising and responding to new threats.
What Actually Changes
- Slower response times — the immune system takes longer to recognise and react to new pathogens.
- Reduced vaccine response — older adults may generate a less robust response to vaccination, which is why booster and higher-dose formulations exist for some age groups.
- Thymus shrinkage — the thymus, which produces T-cells, naturally shrinks with age, reducing new T-cell output.
- Slower wound healing — tied to changes in circulation and immune cell activity.
Inflammaging Explained
Alongside a less responsive immune system, ageing is often accompanied by a low-grade, chronic increase in inflammation — a phenomenon researchers have termed "inflammaging." This background inflammation is thought to contribute to a range of age-related health changes, making inflammation management a relevant focus as you get older.
Supporting Immune Health As You Age
- Stay physically active — regular movement supports circulation and general immune resilience.
- Prioritise protein and micronutrients — adequate nutrition becomes more important, not less, with age.
- Manage inflammation — anti-inflammatory foods and habits may help offset some effects of inflammaging.
- Keep up with recommended vaccinations — discuss age-appropriate vaccination schedules with your doctor.
- Support gut health — the gut microbiome shifts with age and plays a meaningful role in immune function.
Where Turmeric Australia Fits In
Turmeric is one of the more popular natural additions for people managing general inflammation as they age, often paired with magnesium to support normal muscle and nerve function. Neither replaces medical care, but many customers use them as part of a broader healthy-ageing routine.
FAQs
At what age does immune function start to decline?
Changes are gradual and vary between individuals, but research generally identifies noticeable shifts from around age 60 onward, alongside earlier subtle changes.
What is inflammaging?
A term used to describe the low-grade, chronic inflammation that tends to increase with age and is thought to contribute to various age-related health changes.
Can you reverse immune ageing?
Immunosenescence is a natural process that can't be reversed, but lifestyle factors like diet, activity and sleep can support immune resilience as you age.
Should older adults take different supplements?
Nutritional needs can shift with age. Speak to your doctor or pharmacist about what's appropriate for your individual circumstances.
Why do vaccines sometimes work less well in older adults?
A less robust immune response with age can reduce vaccine effectiveness in some cases, which is why age-specific vaccine formulations exist for certain conditions.
Our Simple Recommendation
Immune changes with age are natural, not something to fear — but supporting them with good nutrition, movement and inflammation management can make a meaningful difference to how you feel day to day.
