How Much Selenium Per Day for Women Over 50?

A supplement label with every dose disclosed, illustrating a page on how much selenium per day women over 50 need

Short answer: The general adult reference intake for selenium is about 55 micrograms a day, and it does not rise after 50. Selenium is one of the nutrients where more is genuinely not better — the safe range is narrow, with a tolerable upper limit of around 400 micrograms a day. A supplement that sits at the reference intake, not far above it, is the sensible design.

What selenium is

Selenium is an essential trace mineral, meaning your body needs it in very small amounts and cannot make it itself. It comes mainly from food — Brazil nuts, fish, eggs and grains are common sources, and the amount in plant foods depends on the selenium in the soil they were grown in. Because the requirement is measured in micrograms, small differences in intake add up quickly.

The numbers, honestly

The commonly cited adult reference intake is around 55 micrograms a day. Unlike water-soluble vitamins, selenium has a relatively narrow window: the tolerable upper limit for adults is about 400 micrograms a day, and chronically taking well above that can cause problems rather than benefits. This is the opposite of a nutrient where you would want to stack a large surplus — the goal is to meet the requirement, not exceed it.

Why stacking selenium is easy to do by accident

Because selenium turns up in multivitamins, standalone supplements and food, it is possible to add it from several directions without noticing. A couple of Brazil nuts alone can carry a substantial amount. If you take more than one supplement, it is worth reading each label and adding up the selenium so the total stays comfortably inside the safe range rather than creeping towards the upper limit.

Does anything change after 50?

The requirement itself does not increase with age. There is no established reason a healthy woman over 50 needs more selenium than she did before, and the priority stays the same: meet the reference intake through a varied diet, and treat a supplement as a way to cover the gap on the days your plate does not — not as a reason to double up.

Related questions

Can you take too much selenium?

Yes — selenium has a relatively narrow safe range, with a tolerable upper limit of around 400 micrograms a day for adults. Chronically taking well above that can cause problems, so the aim is to meet the reference intake rather than exceed it. If you take more than one supplement, add up the selenium across all of them.

Do women over 50 need more selenium?

The reference intake does not increase with age. A varied diet usually covers it, and a supplement at the reference intake is there to fill the gap on lower-intake days rather than to push the total higher.

Is it safe to eat Brazil nuts and take a selenium supplement?

Brazil nuts are unusually rich in selenium, so a small handful can carry a large amount on its own. It is fine to have both in principle, but because selenium adds up quickly, keep an eye on the combined total so it stays comfortably inside the safe range. If in doubt, speak to your provider.
