What is Threonine

Threonine is an essential amino acid that is necessary for the proper functioning of the body. It is an alpha-amino acid and is used in the biosynthesis of proteins. Threonine is a polar, uncharged amino acid, and its side chain contains a hydroxyl group, which makes it different from other amino acids. Threonine is abbreviated as Thr or T.

Why we need Threonine

Threonine is an essential amino acid, which means that the body cannot produce it, and it must be obtained from the diet. It is necessary for the proper functioning of the immune system, nervous system, and digestive system. Threonine is involved in the biosynthesis of proteins, antibodies, and enzymes, and it is a precursor for the synthesis of other important compounds such as glycine and serine. Threonine is also involved in the metabolism of fats and the maintenance of proper nitrogen balance in the body.

Where is Threonine found

Threonine is found in many protein-rich foods, including meat, fish, dairy products, eggs, beans, nuts, and seeds. Some plant-based sources of threonine include quinoa, lentils, spinach, and potatoes. Threonine can also be found in dietary supplements and protein powders.

Daily requirements

The daily requirement for threonine varies depending on age, sex, and activity level. The recommended daily intake for adults is 15 mg per kg of body weight. For example, a person who weighs 70 kg would require approximately 1,050 mg of threonine per day. Children, pregnant women, and individuals with certain medical conditions may require higher amounts of threonine.

Threonine deficiency

Threonine deficiency is rare in developed countries, as threonine is found in many common foods. However, individuals who consume a diet that is low in protein or who have certain medical conditions may be at risk of threonine deficiency. Symptoms of threonine deficiency may include fatigue, irritability, decreased immune function, and slow wound healing.

Lysine Threonine

Lysine and threonine are two essential amino acids that work together to support the immune system, build and repair tissues, and maintain proper nitrogen balance in the body. Lysine is necessary for the absorption of calcium and the formation of collagen, while threonine is involved in the biosynthesis of proteins and the maintenance of proper nitrogen balance in the body.

Can you get too much Threonine

It is generally considered safe to consume threonine in amounts found in food and dietary supplements. However, excessive intake of threonine may cause gastrointestinal disturbances, such as nausea, diarrhea, and abdominal cramping. Individuals with certain medical conditions, such as liver or kidney disease, should consult with a healthcare provider before taking threonine supplements.

Should I get Threonine supplements

Most people can obtain sufficient amounts of threonine from a balanced diet that includes protein-rich foods. However, individuals who consume a vegan or vegetarian diet, athletes, and those who are recovering from an injury or surgery may benefit from threonine supplements. As with any dietary supplement, it is important to choose a reputable brand and to follow the recommended dosage.

Fun facts

Threonine was first isolated from casein in 1935.

Threonine is one of the few amino acids that can exist in both L and D forms, but only the L-form is used in the human body.

Threonine is named after the Greek word "thréō", which means "I nourish".
