Basic information:

L-Carnosine is a dipeptide composed of β-alanine and L-histidine. It is often found in organs and tissues such as the brain, heart, skin, muscles, kidneys and stomach. , its content varies with species and parts, especially in muscles, brain and eye lens, and plays an important role in exercise, metabolism and clinical practice. Carnosine has cellular antioxidant, anti-aging and various physiological health functions and medical effects. It has therapeutic effects on hypertension, heart disease, senile cataracts, ulcer healing, etc.


①Antioxidant, reduce free radical damage

L-carnosine can activate cells in the human body and resist aging through two mechanisms: inhibiting glycation and protecting our cells from free radical damage. Loss of cell function and incomplete gene combination will accelerate aging. L-Carnosine also stabilizes cell membranes and reduces brain lipid peroxidation, thereby preventing neurological and brain degeneration.

②Delay skin aging

First of all, the content of L-carnosine in the body decreases with age, and timely supplementation can delay aging. Secondly, L-carnosine can reduce the production of glycation end products (AGEs), a mutated protein that accelerates aging. Finally, L-carnosine also helps reduce cross-linked collagen that causes wrinkles and reduces skin elasticity.


L-carnosine has an inhibitory effect on tyrosinase. The greater the concentration, the stronger the inhibitory effect. L-carnosine also has a photoprotective effect on human skin. L-carnosine is added to cosmetics to have a whitening effect.

④Regulates energy metabolism and protein synthesis

L-carnosine can improve muscle endurance and athletic performance while helping to prevent exercise-related muscle injuries.


①Functional raw materials in the field of daily chemicals: When L-carnosine added to cosmetics, it can effectively slow down the aging of the skin and play a whitening role. It can prevent the growth of human fibroblasts and repair aging human cells. It is a natural anti-aging and antioxidant; it has a significant inhibitory effect on lipid oxidation caused by free radicals and metal ions.

②Raw materials in the pharmaceutical field: L-carnosine has a certain effect in the treatment of chronic diseases such as diabetes and kidney disease.

③Functional raw materials in the health food field: L-carnosine can be used to make health foods and health products to promote muscle growth, improve sports performance, enhance immunity, etc.


At present, the main synthesis method of L-carnosine is chemical synthesis. The main disadvantage is that due to the restriction of side reactions, at least 0.8% of L-histidine will racemize during the reaction process, which reduces the yield of the product; at the same time, it is difficult to separate pure L-carnosine with good optical purity thus product purity is affected. Viablife Biotech selects self-developed biosynthetic technology, and through strict strain screening and advanced automated processing technology, uses renewable carbon sources to synthesize L-carnosine through biological fermentation with high yield and good purity, providing customers with high-quality, Stable L-carnosine product.

Advantages of Viablife' s L-Carnosine:

①Pure appearance and color: Viablife’s L-carnosine is a pure, snow-white powder with uniform particle size.

②Higher purity: Viablife' s L-carnosine synthesis process is a biosynthetic process, with higher purity and fewer impurities.

③Uniform particle size: Viablife' s L-carnosine uses a uniform particle size to strictly control the particle size, making L-carnosine more uniform in particle size and with better fluidity.
