Selenium is an essential trace mineral that helps protect your cells from damage, supports thyroid function, and keeps your immune system working well. It’s needed in only small amounts, but getting enough each day is important for long-term health.
Benefits of selenium
One of selenium’s main jobs is acting as an antioxidant, helping control free radicals and reduce oxidative stress in the body. This matters because oxidative stress is linked to aging and chronic conditions such as heart disease and some cancers.
Selenium is also important for thyroid health because it helps produce and regulate thyroid hormones, which affect metabolism, energy, and body temperature. It supports immune function too, helping the body respond more effectively to illness and infection. Research also suggests selenium may support fertility, brain health, and cognitive function, especially when intake is too low.
Minimum daily requirements of selenium
For most adults, the recommended daily amount is 55 micrograms per day. During pregnancy, the recommendation rises to 60 micrograms per day, and during breastfeeding it increases to 70 micrograms per day.
Children need less than adults, with needs increasing as they grow older. Most people can meet their selenium needs through a balanced diet that includes foods such as seafood, meat, eggs, grains, and Brazil nuts, so supplements are usually not necessary unless a healthcare professional recommends them.
Simple takeaway
Selenium is a small mineral with a big job: it helps protect cells, supports thyroid and immune health, and contributes to overall wellness. For most adults, 55 micrograms per day is enough to meet basic needs.
