What is L-Threonine?

L-threonine is one of the 20 most common natural amino acids that constitute proteins. As an essential amino acid - one not synthesized in the human body - it must be supplied by dietary intake or supplementation.

Threonine is a main component in forming proteins, collagen (Wikipedia), elastin and tooth enamel. It is also crucial for the production of neurotransmitters and overall health of the nervous system.

Research has shown that L-threonine plays an important role in the production of antibodies and in providing overall immune system support.

Threonine is used by strength athletes like bodybuilders and weightlifters because of its role in maintaining protein balance in the body. Threonine increases the absorption of other nutrients, and when combined with other protein sources they become more bioavailable during exercise tasks.

Meats like beef, chicken and turkey are good dietary sources of L-threonine. Deficiencies are relative rare among people consuming a balanced diet, although strict vegetarians and vegans may also want to consider L-threonine supplementation.

Symptoms of L-threonine deficiency include emotional agitation, confusion, fatty liver problems and digestive problems.

Health Benefits of L-Threonine

Threonine is an important component of numerous proteins in the body and is required in forming tooth enamel, elastin and collagen, which is responsible for both healthy skin and wound healing.

The amino acid has a slight glucose-sparing effect and can be converted into glucose by the liver through the process of gluconeogenesis. It is also used as a digestive aid.

Threonine provides support for cardiovascular, liver, central nervous and immune system function.

It assists in the manufacture of glycine and serine, two amino acids that aid in the production of collagen, elastin and muscle tissue.

Threonine strengthens the immune system by helping in the production of antibodies.

Purity and Concentration of L-Threonine

This pharmaceutical-grade amino acid contains no additives, fillers or anti-caking agents.

Suggested Use of L-Threonine

As a dietary supplement, take 2000 milligrams (a scant teaspoon) daily, or as directed by physician. Individual needs vary. You can see the full bulk density/volumetric conversion chart for L-Threonine here.

A serving size of 1 teaspoon is equal to 2671 milligrams (mg), so if you take a little less than a level teaspoon you will be getting about 2500 milligrams (2.5 grams). A serving of 3/4 teaspoon equals 2004 mg.

Potential Side Effects of L-Threonine

L-threonine in safe at suggested serving sizes. Higher amounts can disrupt liver function and cause ammonia toxicity in the body. People with liver or kidney disease should not take this or any other amino acid supplement without first consulting a physician. Getting too much of any one amino acid can throw the citric acid cycle out of balance, which makes the liver and kidneys work harder to eliminate toxins.

Mixing and Solubility of L-Threonine

This product dissolves somewhat slowly in cold water, faster in hot water and is slightly sweet. Mix with water or juice and drink.

The body needs a supply of all the amino acids in order to effectively create and utilize proteins. Those supplementing any of the amino acids should have a balanced intake of all the other amino acids. Being deficient in even one amino acid will lower the efficiency of the other amino acids in your body.

How should I store it?
