Selenium

Source ? Selenium is generally present in foods rich in proteins and certain vegetables. It can be found in seafood, poultry, meat, cereals, oats and whole rice.

What does it do ? Selenium helps keep nails and hair in good health, protects cells against cellular ageing (by playing an antioxidant role) and helps maintain normal thyroid function. It also helps stimulate the body's natural defences, and plays a part in certain metabolic processes such as spermatogenesis.

For whom ? Elderly people, vegetarians and persons with weakened immunity or significant oxygen-related stress (smokers, sporting persons and those in polluted environments).

Recommended intake:

The reference intake values for selenium are 55 mcg daily for an adult. The recommended intake can rise to 100 or even 200 mcg daily for people very active in sport.
