The cells in our body are constantly being renewed. And for their full formation, many nutrients are simply needed. Threonine is one of the important nutritional components necessary for the construction of body cells and the formation of strong immunity.

Threonine rich foods:

General characteristics of threonine

Threonine is an essential amino acid that, along with nineteen other amino acids, participates in the natural synthesis of proteins and enzymes. The monoaminocarboxylic amino acid threonine is found in almost all naturally occurring proteins. Exceptions are low-molecular-weight proteins, protamines, which are present in the body of fish and birds.

Threonine is not produced in the human body on its own, so it must be supplied in sufficient quantities with food. This essential amino acid is especially necessary for children during the rapid growth and development of their body. As a rule, a person is rarely deficient in this amino acid. However, there are exceptions.


In order for our body to function as usual, it needs proteins to be formed every moment, from which the whole body is built. And for this, it is necessary to establish the intake of the amino acid threonine in sufficient quantities.

Daily requirement for threonine

For an adult, the daily rate of threonine is 0,5 grams. Children should consume 3 grams of threonine per day. This is due to the fact that a growing organism needs more building material than an already formed one.

The need for threonine increases:

  • with increased physical activity;
  • during active growth and development of the body;
  • when playing sports (weightlifting, running, swimming);
  • with vegetarianism, when little or no animal protein is consumed;
  • with depression, because threonine coordinates the transmission of nerve impulses in the brain.

The need for threonine decreases:

With age, when the body ceases to need a large amount of building material.

Digestibility of threonine

For the full assimilation of threonine by the body, vitamins of group B (B3 and B6) are necessary. Of the microelements, magnesium has a significant effect on the absorption of the amino acid.

Since threonine is an essential amino acid, its absorption is directly related to the use of foods containing this amino acid. At the same time, there are cases when threonine is not absorbed by the body at all. In this case, the amino acids glycine and serine are prescribed, which are formed from threonine as a result of chemical reactions in the body.

Useful properties of threonine and its effect on the body

Threonine is essential for maintaining normal protein balance. The amino acid improves liver function, strengthens the immune system, and participates in the formation of antibodies. Threonine is essential for maintaining the cardiovascular and nervous system. Participates in the biosynthesis of amino acids glycine and serine, takes part in the formation of collagen.

In addition, threonine perfectly fights liver obesity, has a positive effect on the functioning of the gastrointestinal tract. Threonine actively copes with depression, helps with intolerance to certain substances (for example, wheat gluten).

Interaction with other elements

In order to provide skeletal muscles with high-quality protein, and to protect the heart muscles from premature wear, it is necessary to use threonine together with methionine and aspartic acid. Thanks to this combination of substances, the appearance of the skin and the functioning of the liver lobules are improved. Vitamins B3, B6 and magnesium increase the activity of threonine.

Signs of excess threonine:

Increased levels of uric acid in the body.

Signs of a threonine deficiency:

As mentioned above, a person rarely lacks threonine. The only symptom of a threonine deficiency is muscle weakness, accompanied by protein breakdown. Most often, those who suffer from this are those who avoid eating meat, fish, mushrooms – that is, eating protein foods in insufficient quantities.

Factors affecting the content of threonine in the body

Rational nutrition is a determining factor in the abundance or lack of threonine in the body. The second factor is ecology.

Environmental pollution, soil depletion, the use of compound feed, the cultivation of livestock outside the pasture leads to the fact that the products we eat are poorly saturated with the amino acid threonine.

Therefore, in order to feel good, it is better to buy products from a trusted manufacturer, from which they are more natural than purchased in stores.

Threonine for beauty and health

Since threonine plays an important role in the synthesis of collagen and elastin, adequate content in the body is a necessary component of skin health. Without the presence of the above substances, the skin loses its tone and becomes like parchment. Therefore, to ensure the beauty and health of the skin, it is imperative to consume foods rich in threonine.

In addition, threonine is necessary for the formation of strong tooth enamel, being a structural component of its protein; actively fights fat deposits in the liver, speeds up metabolism, which means it helps to maintain a figure.

The essential amino acid threonine helps to improve mood by preventing the development of depression caused by a lack of this substance. As you know, positive mood and poise are important indicators of physical attractiveness.
