In this study, two AA mixtures, one exclusively consisting of EAAs and the other consisting of 85% EAAs and15% NEAAs, were tested to explore their effects on the viability of both normal and cancer cell lines and to clarify the molecular mechanisms involved. Both mixtures exerted a cell-dependent anti-proliferative, cytotoxic effect involving the inhibition of proteasome activity and the consequent activation of autophagy and apoptosis.
Oral supplementation with branched amino acid appears to reduce the length of hospital stay, decrease morbidity and improve the quality of life, without any changes in mortality. Perioperative supplementation with arginine has shown a reduced incidence of complications and a significant increase in long-term survival.
There is no anabolic resistance or attenuated anabolic potential to intake of 14 g of EAA/leucine or balanced amino acid mixture in advanced (mainly stage III) NSCLC. The high anabolic potential of dietary EAA in cancer patients is independent of their nutritional status, systemic inflammatory response or disease trajectory, suggesting a key role of EAA in new nutritional approaches to prevent muscle loss, thereby improving outcome of patients with advanced cancer.
In cancer patients, conventional nutritional supplementation is ineffective in stimulating muscle protein synthesis. This anabolic resistance can be overcome with a specially formulated nutritional supplement.
In addition to being substrates, some amino acids, for example leucine, act as intracellular signals to promote protein synthesis. Recent acute studies demonstrated that provision of amino acids, sufficient to considerably elevate circulating leucine concentrations concurrent with other amino acid and nutrient availability, resulted in significant protein anabolism in cancer patients. This occurred even during weight loss and inflammation
These findings suggest that higher methionine intake may reduce the risk of pancreatic cancer.
Amino acids are the “alphabet” of protein structure, determining many of the properties of proteins. Amino acids are rapidly absorbed and readily available in the blood. In the cell, amino acids maintain protein stores and counteract hormone-mediated catabolic stimuli. Thus, amino acid supplementation may be effective in counteracting the metabolic and morphologic consequences of the hypercatabolic state of chronic diseases such as heart failure, diabetes mellitus, or liver cirrhosis.
In contrast to protein, crystalline AA in the diet do not undergo digestion and are directly available for absorption by the small intestine. Therefore, they are absorbed into enterocytes and appear in the portal vein more rapidly than protein-bound AA.

Use of single amino acids (e.g., leucine), or groups of amino acids (e.g., branched chain amino acids) is ineffective, as all EAAs must be consumed to support a clinically significant increase in protein synthesis.
Regardless of the approach, ensuring an adequate availability of dietary essential amino acids is necessary for pharmacologic therapy to result in an increased rate of protein synthesis.
This comprehensive compilation highlights key publications and resources focused on amino acids. These references cover various aspects such as biochemistry, metabolism, nutritional significance, diagnostics, and therapeutic applications of amino acids.
With a simple blood test we’re able to discover health conditions before symptoms even appear and then mitigate them with amino acid supplements personalised to your DNA.
Amino Acid Science Ltd pioneered this technique and evidence-based algorithm to undertake human amino acid profiling that enables a comprehensive physical, mental and nutritional check-up and thereby providing personalized supplementation tailored to the needs of an individual.
MedCity, UK endorsed this business as an innovation in Digital Health in 2020.
Amino acid analysis is a laboratory technique used to analyze the types and quantities of amino acids present in blood sample. Amino acids are the building blocks of proteins and play critical roles in a wide range of biological processes, including the synthesis of proteins, neurotransmitters, and other molecules.
No, Amino acid analysis is not a new method. It has been a well-established and widely used method in biochemistry and nutrition research for many years. For the past 40 years, the HPLC and LC MS/MS methods have been used to accurately measure the levels of amino acids and metabolites that play a role in all of the body's functions.
What is new is we developed an amino acid analysis interpretation system that provides an evidence-based assessment of health and nutritional status and supplement recommendation to prevent health risks and improve physical and mental health.
This system called as AminoCheck was developed by Amino Acid Science Ltd established in Imperial College Innovation Hub, London, based on the studies of Dr. Aydın Duygu. The UK government has recognized Dr. Aydın Duygu as innovator in the field of medical technology and digital health.
AminoCheck analysis is an early warning system for future health problems or undetected diseases. Apart from health status and risks, it clearly reveals which nutrient support we need. So, you don't have to take random supplements.
Amino acid analysis can provide valuable insights into our health status and help guide nutritional and medical interventions to improve health outcomes.
Here are some examples:
The analyses performed for checkup purposes show positive results if there is a disease. Routine checkup controls such as blood tests, urine tests, and physical examinations are used to screen for a wide range of health conditions and assess overall health status. These tests typically measure markers such as cholesterol, blood glucose, liver enzymes, and kidney function.
In contrast, amino acid analysis is a more specialized test that specifically evaluates protein and amino acid metabolism that is related to all biological functions of human beings.
AminoCheck provides information about the types and quantities of amino acids present in a sample, which can be used to diagnose metabolic and psychologic disorders, monitor disease progression, and assess nutritional status.
Amino acids play a role in all of our body's functions. Even a deficiency or imbalance in a single amino acid affects the functions of other amino acids. Many factors, such as intense stress, heavy exercise, unbalanced nutrition, and sadness, can cause a decrease or imbalance in amino acid levels. Therefore, by conducting an AminoCheck analysis it is possible to obtain information about the causes of many conditions from insomnia to changes in appetite, from hair loss to depression.
AminoCheck provides advanced amino acid testing and personalised amino acid supplements to optimise health, prevent conditions, and support treatment for various health issues.
