Effect of an Anti-ageing Supplement on Oxidative Stress

Ageing is characterized by a progressive decline in the efficiency of physiological function and by the increased susceptibility to disease and death. Most ageing-associated diseases develop silently for many years before symptoms appear, leading to irreversible pathological conditions. Examples of these diseases are Alzheimer's, Parkinson's, osteoporosis, diabetes, cardiovascular disease and also cancer. Typically, patients are treated when most of the damage has already occurred, and existing drugs can rarely cure these diseases, but merely slow down further progression of the disease. Therefore, preventive measures that may delay the onset of these diseases can hold the best promise for healthy ageing. of the most plausible and acceptable explanations for the mechanistic basis of aging is the "free radical theory of aging". This theory postulates that aging and its related diseases are the consequence of free radical-induced damage to cellular macromolecules and the inability to counterbalance these changes by endogenous anti-oxidant defences. ProManna is a novel and safe food supplement that aims to decrease free radical-induced damage, thereby contributing to healthy ageing.
