If you’ve researched any hair supplement products, you probably noticed one of the ingredients is selenium. But what is it? Selenium is a naturally occurring essential mineral, which the body acquires from your diet. You only need a small amount of selenium, but be sure that the role it plays is big.
What does selenium do?
Selenium has antioxidant and anti-inflammatory properties, and it is important for many body processes to function normally, including your immune, endocrine and cardiovascular systems. Cognitive functions and fertility are also supported by selenium. Some studies have found low selenium levels to be linked to heart disease, infertility, thyroid problems and even some types of cancer.
The antioxidant properties help to stop free radicals from damaging cells in the body.
Sources of selenium
Selenium can be found in a variety of foods, so it’s easy to ensure it’s a part of your diet. It’s most commonly found in seafood and other animal proteins. If you’re a vegetarian or vegan, though, don’t worry – selenium is also found in nuts and many whole grains.
Here’s are the top foods for sources of selenium:
- Brazil nuts
- Tuna
- Halibut
- Turkey
- Cottage cheese
- Brown rice
- Sunflower seeds
- Eggs
- Mushrooms
- Spinach
The National Institutes of Health, or NIH, recommends 55 mcg (micrograms) daily allowance for adults. For example, one ounce of Brazil nuts contains 544 mcg.
Selenium and your hair
The antioxidant properties of selenium bring on the most benefits for your hair. Selenium works in tandem with enzymes to boost hair growth and reduce dandruff. You’ll find this essential mineral in many anti-dandruff shampoo products. In addition, selenium helps to prevent and repair damage to hair follicles. Pollution, UV rays and other environmental toxins can affect on your hair’s health.
A selenium deficiency, although rare, can cause hair loss as well. Deficiencies have been most found in people who smoke, drink excessive amounts of alcohol or take birth control pills as these things hinder the body from properly absorbing selenium.
On the other hand, excessive selenium in the body can cause hair and nail loss as well. The major signs of excess intake are a garlic odor in the breath and metallic taste in the mouth.
It’s critical your body is fueled with all the vitamins and nutrients it needs. Be sure to eat a balanced diet and maintain a healthy lifestyle. Your hair will thank you!
