Older adults often take supplements to boost health. But do they really help? A closer look reveals that some supplements are useful, while others may not be necessary or even harmful.

Many people over 65 take dietary supplements to stay healthy. Vitamins, minerals, and other products promise energy boosts, immunity support, brain health, and more. But is this a good idea? For those with adequate nutrition, many supplements offer little benefit. Some may even cause harm.

Older adults face unique challenges. Nutritional deficiencies become common as appetite decreases, oral health worsens, and chronic illnesses increase. Medications can affect how nutrients are absorbed or used. Oral health problems make chewing difficult, reducing dietary variety.

Vitamin B12 is a clear example of when supplements can help. Deficiency becomes more common with age due to reduced stomach acid production. Low B12 causes anaemia, fatigue, nerve problems, and memory issues. Certain medicines increase the risk further. High-dose oral B12 often works well, while some people need injections.

Folate is also important for red blood cell formation and DNA production. Low folate can raise homocysteine, linked to cardiovascular disease and cognitive decline. Folate or other B vitamins may help specific groups, but B12 deficiency should be considered first.

Vitamin D is another concern. Deficiency is more likely in older adults with limited sun exposure, reduced mobility, darker skin, care-home residence, or diets low in vitamin D-rich foods. Supplementation may be appropriate when levels are low, sun exposure is limited, or someone has osteoporosis or high fracture risk.

Calcium and magnesium matter for bone, muscle, and nerve function. Where possible, they should come from food. Supplements may be useful when dietary intake is insufficient or osteoporosis is present, but excessive intake should be avoided.

Multivitamins can be helpful for older adults who eat very little or have specific deficiencies. However, supplementation should be targeted based on confirmed deficiencies, clear risk factors, medication use, or evidence that someone is not getting enough from food.
