What are the most important nutrients for healthy ageing?
Several nutrients are commonly prioritised as we age, including vitamin D, vitamin B12, calcium, omega-3 fatty acids and magnesium. These nutrients support a range of normal body functions, including bone health, energy metabolism, nervous system function, muscle function, cardiovascular health and overall wellbeing. Individual nutrient needs vary depending on age, diet, lifestyle and overall health.
Why do vitamin D needs change with age?
As we get older, the skin becomes less efficient at producing vitamin D in response to sunlight. Older adults may also spend less time outdoors, which can further reduce vitamin D production. Together, these factors can make maintaining adequate vitamin D status more challenging, even in Australia's sunny climate.
How much calcium do over-60s need?
The Australian Nutrient Reference Values published by the NHMRC provide age- and sex-specific recommendations for calcium intake. Recommended calcium requirements are generally higher for women after menopause due to changes in bone health. Your GP or an accredited practising dietitian can help determine whether your dietary intake meets your individual needs.
Why is magnesium often mentioned for healthy ageing?
Magnesium contributes to many normal processes in the body, including muscle function, nerve signalling, energy production and protein synthesis. Because dietary magnesium intake may be lower than recommended in some older adults, it is frequently discussed as part of healthy ageing and overall nutritional wellbeing.
Do I need omega-3 supplements if I don't eat fish?
If you rarely eat oily fish, an omega-3 supplement such as fish oil or krill oil may help complement your dietary intake. Whether supplementation is appropriate depends on your individual diet and health needs, and it's a good idea to discuss this with a healthcare professional.
Can I get all 5 of these nutrients from diet alone?
Many people can meet their nutritional needs through a varied, balanced diet. However, vitamin B12 can be an exception for some older adults because age-related changes in digestion may reduce absorption from food. If you're concerned about your nutrient intake, your GP or an accredited practising dietitian can assess your diet and advise whether supplementation may be appropriate.
Should I take all 5 nutrients as separate supplements?
Not necessarily. Depending on your nutritional needs, a multivitamin formulated for older adults may provide several nutrients in one product. Others may benefit from targeted supplementation. The most appropriate approach depends on your diet, existing health conditions and advice from your healthcare professional.
Are these nutrient needs the same for men and women?
Not always. Recommended intakes for some nutrients, including calcium and iron, differ according to age, sex and life stage. For example, calcium requirements generally increase for women after menopause. The NHMRC Nutrient Reference Values provide detailed recommendations for different age groups and sexes, and your healthcare professional can help interpret these in the context of your individual needs.
