If you’re not running low on this mineral, taking it in supplement form may hurt your health.
Selenium has seen a burst in popularity in recent years. It’s a mineral that’s important for your health; your body uses it to fight off free-radicals and keep your immune system working properly, but it only requires tiny amounts.
Some people may be getting too much selenium. In a new article from the journal The Lancet, an expert lays out the reasons why people should be cautious with the mineral.
For example, people who take in enough selenium from their food may be more likely to develop Type 2 diabetes if they take more in supplement form. Good sources of selenium in food include Brazil nuts, canned tuna in water, cod, turkey and chicken.
The take-home lesson is that having too little selenium is bad for people’s health, but so is having too much.
