Mineral

Selenium

Selenium is incorporated into specialised proteins called selenoproteins. These include antioxidant enzymes and enzymes that help regulate active thyroid hormones.

It contributes to normal antioxidant protection, thyroid function, immune activity and maintenance of hair and nails.

In everyday life, Selenium supports antioxidant enzymes, normal thyroid activity and the everyday maintenance of healthy hair, nails and immune function.

The elemental mineral amount is more meaningful than the weight of its source compound.

Ingredient overview

What it is

Selenium is incorporated into specialised proteins called selenoproteins. These include antioxidant enzymes and enzymes that help regulate active thyroid hormones.

  • Scientific identity: Selenium; incorporation: As selenocysteine, the 21st amino acid.
  • How it works: Absorbed efficiently: Dietary selenium, largely as selenomethionine, is taken up well from the small intestine. Converted to selenocysteine: It is incorporated into proteins as a special amino acid rather than acting as a loose cofactor.
  • Primary function: It contributes to normal antioxidant protection, thyroid function, immune activity and maintenance of hair and nails.
  • What it supports: Selenium supports antioxidant enzymes, normal thyroid activity and the everyday maintenance of healthy hair, nails and immune function.
  • Important consideration: The elemental mineral amount is more meaningful than the weight of its source compound.

Formulation rationale

Why we use it

CARPEDIEM selected Selenium for a clearly defined role within a thoughtfully balanced formulation.

  • Formulation purpose: It contributes to normal antioxidant protection, thyroid function, immune activity and maintenance of hair and nails.
  • Used in: CARPEDIEM Hair Skin Nails, CARPEDIEM MultiTeen and CARPEDIEM MultiWomen and other appropriate CARPEDIEM formulations.
  • Works alongside: Selenium complements Zinc, Iodine and Vitamin E to support balanced daily mineral nutrition.
  • Meaningful contribution: Selenium supports antioxidant enzymes, normal thyroid activity and the everyday maintenance of healthy hair, nails and immune function. Supports normal immune-system function through essential selenium-containing proteins.
  • Quality and scientific context: The elemental mineral amount is more meaningful than the weight of its source compound. Research is shown only when an ingredient-specific study demonstrates a relevant benefit.
