Conditionally Essential Amino Acids: How To Use Them For Your Benefit

Six amino acids are considered conditionally essential or semi-essential. All amino acids are vital for your health, but not all are essential.

Conditionally essential means that synthesis of them can be limited under special conditions, such as in infants or individuals in catabolic distress. There may also be certain states during adult life when a particular amino acid becomes conditionally essential.

If you are looking for a specific conditionally essential amino acid, I recommend you use the expanded toc to find it.

What Are Amino Acids?

Amino acids are the basic building blocks of proteins 🗗. There are hundreds of amino acids found in nature. Only about 20 of them are needed to make all the proteins found in the human body and most other forms of life.

How Can Amino Acids Become Conditionally Essential?

When the body experiences periods of extreme trauma or stress from thermal injury, sepsis, surgery, or wounds, non-essential amino acids become conditionally essential.

Or during the first years of a child's life, where the enzymes needed to synthesize a particular non-essential amino acid have not been developed yet.

The physiological demand for these non-essential amino acids becomes greater than the ability to synthesize them. As a result, these non-essential amino acids must get provided by the diet.
