Filling the gaps

Vitamins for older adults

Why supplementation can matter more as you age, and what to know before you start.

As we age, our nutrient needs change and it becomes harder to get everything from food alone. Many older adults don't eat enough of the right foods, or regularly rely on highly processed, nutrient-poor options without realising it.

I'll explain why vitamins matter more with age, the role diet plays, and why some become especially important once the body no longer produces or absorbs them as well as it used to.

This is an overview from me, not detailed guidance on any one vitamin. I'll cover individual vitamins properly in separate posts.

Food comes first. But for many older adults, smart supplementation helps fill the gaps that diet alone no longer covers.

What changes

Why vitamin needs change as we age

Lower absorption

The digestive system becomes less efficient at extracting certain nutrients from food.

Higher needs for repair and protection

Older bodies rely more on vitamins for cell repair, immune function, and reducing oxidative stress.

Medication interactions

Common medications can affect how the body uses or stores particular vitamins.

Reduced sun exposure and skin changes

Affects how well the body makes certain vitamins naturally.

Appetite and dietary changes

Smaller appetites, dental issues, or convenience foods can lead to lower overall nutrient intake.

Chronic conditions

Health issues can increase requirements or reduce the body's ability to use certain vitamins effectively.

Before you start

Getting supplementation right

Food first, always

Supplements fill gaps. They don't replace a decent diet, so get that right before you reach for a bottle.

Quality varies hugely

Look for products that have been independently tested. Cheap and poorly absorbed isn't a bargain.

Talk to your doctor first

Some vitamins interact with medication or existing conditions. Get advice before you start taking anything new.
