What is Threonine?

Threonine is an essential amino acid, i.e., it is vital for your health, but it cannot be synthesized by your body and therefore has to be obtained from a diet.

Foods high in Threonine:

  • Soya Foods (Tofu, Natto, Tempeh, etc)
  • Pumpkin Seeds
  • Beans & Lentils

This amino acid supports central nervous, cardiovascular, liver, and immune system functioning – just to name a few. Moreover, it helps in the synthesis of glycine and serine which, in their turn, assist in the production of collagen, elastin, and muscle tissue. In addition, Threonine aids building strong bones and tooth enamel and speeds up a wound healing process after trauma or surgery by boosting up the immune system.

Low levels:

Low levels can result in hypoglycemic symptoms, particularly if glycine or serine is also low. Supplement threonine/BCAAs.

High levels:

High levels can be due to excessive dietary intake or possible insufficient metabolism of threonine. The initial step requires B6, and zinc is needed to phosphorylate B6 to its active coenzyme form. So supplementation with B6 and zinc can be helpful.
