Selenium

INFORMATION

Uses

Selenium is used in the treatment of nutritional defeciencies.

How it works

Selenium is a trace element that is essential in small amounts in the body. Selenium is important in the functioning of selenium dependent chemical (enzymes) in the body called as selanoproteins. Selenium is an integral part of glutathione peroxidases (GPx) that act as potent antioxidant (substance that protects against cell damage) by neutralizing the free radicals (waste products formed in the body during energy production) such as reactive oxygen and nitrogen species. Thus selenium participates in vital redox reactions of the body. Also, a selenoprotein (iodothyronine deiodinases) is essential for the conversion of thyroxine (T4) to the biologically active thyroid hormone triiodothyronine (T3) thereby indicating the importance of selenium in thyroid hormone functioning.

Expert advice

Do not take this drug if you are allergic to selenium. Always consult your doctor before using selenium supplementation:
  • If you have chronic kidney disease (or if you are on dialysis).

Frequently asked questions

Selenium

Q.Can I take selenium with synthyroid/ levothyroxine/ armour thyroid/ thyroxin?
There are no known interactions of selenium with any thyroid preparations such as synthyroid/ levothyroxine/ armour thyroid/ thyroxin. Selenium which is a part of selenoprotein (iodothyronine deiodinases) is essential for the conversion of thyroxine (T4) to the biologically active thyroid hormone triiodothyronine (T3) thereby it is important in thyroid hormone functioning

Q.Can I take selenium with calcium?
There are no known interactions of selenium with minerals such as calcium

Q.Can I take selenium with other vitamins/ vitamin C/ zinc?
Yes. Selenium (gluthathione peroxidase) has been reported to support the activity of vitamin E in limiting the oxidation of lipids (fats). Selenium also interacts with zinc (it affects cellular redox status). Selenium can, however, be taken with vitamins/ zinc; the combinations are available as a part of multivitamin preparation

Q.Can I take selenium with statins?
There are no known interactions of selenium with statins. Always follow the advice of the doctor regarding its use

Q.Can I take selenium with warfarin?
There are no known interactions of selenium with warfarin. Always follow the advice of the doctor regarding its use.
