  L-Carnosine

  Carnosine (beta-alanyl-L-histidine) is a of the and . It is highly concentrated in and .

  Researchers in Britain, South Korea, Russia and other countries have shown that carnosine has a number of properties that may be beneficial. Carnosine has been proven to scavenge reactive oxygen species (ROS) as well as alpha-beta unsaturated formed from peroxidation of cell membrane during .

  Carnosine can oppose and it can metal ions. Chronic glycolysis is suspected to accelerate aging. Carnosine was found to inhibit diabetic nephropathy by protecting the podocytes and mesangial cells. Because of its antioxidant, antiglycator and metal chelator properties, carnosine supplements have been proposed as a general therapy.

  Some studies have detected beneficial effects of N- in preventing and treating cataracts of the eyes; in one of these, carnosine was found to reduce cloudiness in rat lenses that were exposed to guanidine to cause cataracts. However, claims that carnosine confers these and other posited ophthamological benefits are, as of yet, insufficiently supported for endorsement by the mainstream medical community; Britain's Royal College of Ophthamologists, for instance, has asserted that neither safety nor efficacy has been sufficiently demonstrated to recommend carnosine's use as a topical treatment for cataracts.

  A small 2002 study reported that carnosine improved on a measure of socialization and receptive vocabulary in children with . Improvement in this study could have been due to maturation, educational interventions, placebo effect, or other confounds that were not addressed in the study design. Supplemental carnosine may increase levels, which can explain the sometimes seen in high doses.^[]

  Typical diets are thought to be lacking in carnosine, but whether this has a detrimental effect on vegetarians is controversial.
