Amino Acid Profile

The determination of the concentration of free amino acids in blood samples provides new, precise insights into individual health status

lifespin has developed a unique method to capture a digital snapshot of an individual’s amino acid profile.
Determining the amino acid profile enables a physician systematic mapping across health conditions for prevention, diagnostics and monitoring of treatment success.

The importance of amino acids

Amino acids are involved in many important roles in your body
Amino acids are the basic building blocks for peptides and proteins.
Amino acids regulate metabolic pathways involved in cell maintenance, growth, reproduction and immunity.
Ensuring the optimal balance of amino acid concentrations is critical to maintaining physiological processes.
The distribution of amino acid concentrations can be used as an indicator of the health status of adult individuals.

Free amino acids in the blood are more readily available for use by the body than protein-bound forms.

Rapid absorption

Free amino acids are readily absorbed by the intestinal wall, whereas protein-bound amino acids need to be broken down into their individual components before they can be absorbed.


Free amino acids are transported in the blood more easily than protein-bound amino acids. This is because free amino acids are not bound to a carrier protein and can move across cell membranes more easily.


Free amino acids can be used for protein synthesis more readily than protein-bound amino acids. This is because free amino acids do not need to be released from the protein before they can be used


The concentration of free amino acids in the blood can be rapidly adjusted by the liver in response to changing metabolic demands. In contrast, the release of amino acids from protein-bound forms is slower and less responsive to changes in demand.

The analysis of the concentration of free amino acids can be helpful for

Nutritional assessment and identifying possible nutrient deficiencies

Monitoring the function of organs and organ systems

Medical diagnostics to identify certain health conditions, including metabolic disorders, and to monitor recovery

Amino acid deficiency

It can be observed in various conditions

Malnutrition is commonly observed in the elderly and individuals with poor protein intake, such as vegetarians and vegans. This can lead to various health issues.

Gastrointestinal diseases, including leaky gut and malabsorption, are often associated with malnutrition. Glutamine is crucial for maintaining gut lining health.

Sarcopenia refers to the loss of muscle mass and strength that exceeds the normal age-related decline. Deficiency in leucine, isoleucine, and valine, is a common trigger for sarcopenia in old age.

The amino acids lysine and threonine are crucial building blocks for the formation of antibodies, which play a significant role in strengthening the immune system and fighting infections.

Glutamine is a vital amino acid that promotes a relaxed mental state by playing important roles in neurotransmitter synthesis and brain function.

The most common symptom of Long-Covid is exhaustion or fatigue, which may be due to the undersupply of amino acids to mitochondria, the powerhouses of cells that are essential for energy metabolism and optimal body performance.

Elevated level of amino acid

It is a strong sign and shows that there is a problem with the body’s ability to metabolize that amino acid 

Such aminoacidopathy can be associated with diseases such as liver cirrhosis and NAFL (especially tyrosine, methionine).

Elevated isoleucine, leucine and valine levels may be signs of fasting.
