Carnosine and health

  • Extending cell health life – carnosine may reduce the destruction of valuable proteins and DNA by sugar molecules (called glycosylation).

Carnosine may help prevent damage from glycosylation, allowing the body to to function more optimally – by supporting healthy aging and cellular rejuvenation
  • Toxic metal binder – carnosine chelates metals in the body. It reacts with toxic by-products of metabolism and eliminates them from the body. It stabilises the cells, making them more resistant to injury, and boosts the immune system
  • Cataracts – studies have shown carnosine drops have been 100% effective in cases of primary senile cataract and 80% effective in cases of mature senile cataracts
