Best 10 Benefits of Selenium

1. Prevents dandruff

Dandruff is often caused by malassezia, a yeast like fungus. Regular intake of selenium can kill this fungus and relieve you of dandruff, making your scalp hydrated and healthy again.

2. Slows aging

Selenium aids in producing and utilizing vitamin E, which is essential in keeping cells rejuvenated and healthy. Adequate selenium also protects the skin from sun damage.

3. Acts as an antioxidant

Selenium acts as an antioxidant, meaning it assists in reducing free radicals in the body. This fights oxidative stress and aids in defending against some types of cancer.

4. Boosts immunity

This element protects the body from numerous autoimmune disorders such as HIV. It also slows the progression of HIV into AIDS.

5. Promotes cardiovascular health

Healthy blood circulation is vital in maintaining good cardiovascular health. Selenium reduces oxidative stress, allowing blood to flow through blood vessels, arteries, and the heart more freely.

6. Strengthens hair

Is your hair thinning or falling out? Selenium may reverse these trends. It transports protein to the hair, which increases hair strength and volume

7. Filters blood

Selenium is a natural blood cleanser. Its antioxidant properties filter free radicals out of the blood and can even increase the efficacy of treatments such as chemotherapy and kidney dialysis.

8. Treats diabetes

Research has shown selenium to be a useful supplement to insulin therapy. Its ability to lower blood sugar and restore glucose metabolism make it a worthwhile investment for diabetics.

9. Boosts reproductive health

A low selenium level elevates the risk of a first-trimester miscarriage. In men, increased selenium can boost fertility and aid in producing more sperm.

10. Detoxifies the body

Again the antioxidant properties come into play. Especially when paired with other antioxidants such as vitamin C, selenium is beneficial in ridding the body of harmful disease-causing toxins.
