Everything You Need to Know About Selenium

If you’ve heard about selenium but aren’t quite sure what it does, you’re not alone. Selenium is a trace mineral that your body needs in tiny amounts, but despite being small, it plays a big role in keeping you healthy. It acts as a powerful antioxidant, helps the immune system, and even supports thyroid function.

Getting enough selenium from your diet is usually possible if you eat a variety of foods like nuts, seafood, and certain grains. However, some people might not get sufficient selenium, especially if they live in areas where the soil lacks this mineral. That’s when supplements come into play, but it’s important not to overdo it.

Why Is Selenium Important?

Selenium’s antioxidant properties help protect your cells from damage caused by free radicals — those unstable molecules linked to aging and disease. This protection is crucial because it supports your body’s defense systems and can even influence inflammation levels.

Besides the immune boost, selenium plays a key role in thyroid health. It helps convert thyroid hormones into their active forms, which means it supports your metabolism and energy levels.

How to Use Selenium Safely

Taking selenium supplements can seem like a good idea if you’re feeling sluggish or want to boost immunity, but too much can cause problems. Symptoms of excess selenium include stomach upset, hair loss, or even nerve damage in severe cases. The recommended daily amount usually ranges from 55 to 70 micrograms for most adults.

To stay safe, consider checking your selenium levels through a healthcare provider before starting supplements, especially if you already get selenium in your diet regularly. If you decide to supplement, stick to doses recommended by health experts and choose reputable product brands to avoid contamination or dosing errors.

In a nutshell, selenium is a small but mighty nutrient you shouldn’t overlook. Whether you get it from Brazil nuts, seafood, or supplements, it helps keep you feeling sharp, strong, and well. Just remember: balance is key when it comes to any supplement.
