Grape skin extract improves muscle function and extends the lifespan of flies with Parkinson's disease, a study shows.The neuroprotective effect of grape skin extract was due to its potential to rescue mitochondria - cells' powerhouses - from defects caused by the disease.
Besides polyphenols, grape skin and seeds also contain anti-oxidative components, including proanthocyanidine and quarcetin, which may actively contribute to protecting against oxidative stress and mediated tissue injury.
Oxidative stress is an imbalance between the production of free radicals and the ability of cells to detoxify them. These free radicals, or reactive oxygen species, are harmful to the cells and are associated with a number of diseases, including Parkinson's disease.Packaging & Delivery
