Threonine an amino acid essential for the human body.
Amino acids are the building blocks of proteins. Most proteins in the human body are composed of 21 amino acids.
Threonine contributes to many bodily functions, including:
Threonine promotes protein synthesis and turnover.
Threonine plays an important role in the maintenance of the intestinal barrier (1).

Do you want to know your personal recommendations ?
The FNB (Food and Nutrition Board of the Institute of Medicine) set its recommendations for threonine at 27 mg per gram of proteins (3).
They also recommend that proteins intake for most people should be between 10 % and 30 % of total Calories. This is called the “adequate macronutrient distribution range” (AMDR) and is based on decreasing risk of chronic disease and providing adequate intake of other nutrients.
In our app, the default value is set at 15 % of total calories, which is inside the AMDR and bases on complementing the values for carbohydrates and fats.
To get your threonine recommendation expressed in gram, we combine the above recommendations.
The FNB did not establish an upper limit because adequate data from human or animal studies were lacking. This does not mean that there is no potential for adverse effects resulting from high intakes of threonine from dietary supplements. Since data are limited, caution may be warranted.
