Threonine Health Benefits: The Essential Amino Acids Guide

Threonine Health Benefits: The Essential Amino Acids Guide

If you’ve been reading our blogs, you’re probably aware that amino acids play an essential role in maintaining good health—no matter our age. Today, we’ll break down one of the essential amino acids, Threonine.

Ok, so what are amino acids, and why do I need them?

Amino acids are organic compounds that combine to produce proteins and work together to synthesize hormones and neurotransmitters in your body. There are 20 in total—all of which are necessary for optimal health—of which nine are considered “essential.”

Why are they called essential amino acids (EAAs)?

Essential amino acids (EAAs) aren’t made naturally in the body, so they need to be obtained through diet. When we don’t consume enough foods or supplements with these vital organic compounds, we can experience a range of health issues.


Threonine, pronounced three-uh-neen is one of nine essential amino acids your body needs to function properly. Aiding in maintaining healthy skin, teeth, collagen, elastin, and muscle tissue, it also helps with digestion, metabolism and preventing fat buildup in the liver.

Threonine has been used to treat intestinal disorders and indigestion and can be used to help those suffering from depression and anxiety. Recently it has been shown to have promising sleep-promoting effects, which may prove helpful for those who have insomnia and other sleep disorders.

When was Threonine discovered?

William Cumming Rose, an American biochemist and nutritionist discovered Threonine in 1936. Similar in structure to its namesake, threonic acid, Threonine was the last of the 20 amino acids to be identified. Rose’s research, assisted by Curtis Meyer, determined just how vital amino acids are to the human body and helped us better understand how proteins are created.

Which foods contain Threonine?

Because our bodies don’t create Threonine naturally, we have to obtain it through our diet to ensure we’re keeping ourselves in tip-top shape. Many foods are high in Threonine, including:

- lean beef, lamb, pork, chicken
- milk and cheese
- carrots, bananas
- edamame, kidney beans, lentils
- and more!

By simply eating enough foods high in Threonine, you can help prevent a deficiency and any possibly related adverse health effects.

How much Threonine should I have each day?

Although the recommended daily intake of Threonine varies, one study by the National Research Council (US) suggests 15mg per day is adequate for most adults.

What happens if I don’t get enough Threonine?

If your body doesn’t get enough amino acids, you may experience a deficiency. This can cause muscle loss, fatigue, memory loss, weakness, depression, and many other negative symptoms. If you have a Threonine deficiency specifically, you may suffer from digestive issues, increased liver fat, mental fogginess, and other problems.
