Uses of Tin

Tin has a wide range of uses in the body, including:

  • Collagen synthesis: Tin is a cofactor for the enzyme lysyl hydroxylase, which is necessary for the synthesis of collagen. Collagen is a protein that provides structural support to the skin, bones, and organs.
  • Immune function: Tin is essential for the development and function of T cells, which are a type of white blood cell that helps to protect the body from infection.
  • Antioxidant activity: Tin has antioxidant properties and may help to protect the body from damage caused by free radicals.
  • Tin ear: Tin is used in the treatment of tinnitus, a condition characterized by a ringing or buzzing sound in the ears.
  • Cancer treatment: Tin compounds have been shown to have anti-cancer properties and may be used as a complementary therapy in the treatment of certain types of cancer.

Sources of Tin

Tin is found in a variety of foods, including:

  • Meat and poultry: Tin is found in the liver, kidneys, and muscle tissue of meat and poultry.

  • Whole grains: Tin is found in brown rice and oats.

Tin is also available as a supplement in the form of tin chloride or tin gluconate.

The recommended daily intake of tin is 10-15 mg. However, there is limited data on the toxicity of tin, and some studies have suggested that intakes of up to 25 mg/day are safe.
