Threonine is an essential amino acid, it is obtained in the diet from beans, Brewer’s Yeast, dairy products, eggs, fish, legumes, meat, nuts, seafood, seeds, soy, whey, and whole grains. As of all amino acids, threonine is important for the formation of proteins, however it is especially required for the production of tooth enamel, collagen, and elasrin. Threonine helps to metabolize fat and prevents a build-up of fat developing in the liver; it is also useful for intestinal disorders, and indigestion.

Threonine can help to stabilize the blood sugar as it can be converted into glucose in the liver by gluconeogenesis. People who have been burned, wounded, or undergone surgery have higher than normal levels of threonine in their urine. This indicates that the amino acid is released from the tissues following trauma. Recent research indicates that increasing threonine intake during these periods may aid the recovery process. Several study findings have suggested that threonine might be able to decrease the muscle spasticity that often occurs with MS, however this use of threonine has not been clinically proven.

There are no known signs or symptoms of threonine deficiency.

There is no official recommended daily allowance (RDA) for threonine, however suggested doses for therapeutic purposes range from 300 to 1,200 mg per day.

MAXIMUM SAFE LEVEL: Not established

None known. People with kidney disease or liver disease should consult their doctor before taking threonine.
