L-Carnosine
Uses of L-Carnosine
L-Carnosine is a naturally occurring dipeptide sold as a dietary supplement.
L-Carnosine is commonly used for:
- Nutritional supplementation: Provides carnosine, which has antioxidant and pH-buffering roles in physiological processes.
- Research use: Has been studied in neurological and metabolic conditions, but current evidence is insufficient to establish it as a treatment.
L-Carnosine should not be presented as a proven treatment for autism spectrum disorder, learning disorders, or cognitive impairment.
Side effects of L-Carnosine
Mild gastrointestinal discomfort
Nausea
Stomach upset
Allergic reactions in sensitive individuals
How L-Carnosine works
- L-Carnosine is a naturally occurring dipeptide made up of two amino acids.
- It acts as an antioxidant, neutralising harmful free radicals and reducing oxidative stress, which can help protect cells, including nerve cells, from damage.
- It also helps prevent the build-up of advanced glycation end products (AGEs), compounds that accumulate in the body over time and are linked to ageing and various health conditions.
- As a metal chelator, L-Carnosine binds to metal ions such as zinc and copper, helping regulate their activity and limiting the oxidative stress they can cause.
- In addition, it supports muscle function by helping buffer lactic acid build-up in muscle cells, which may reduce fatigue during physical activity.
