This plant substance has neuroprotective benefits.

Alzheimer's disease is a progressive neurodegenerative disorder of the cortex and hippocampus, which leads to cognitive impairment if nothing is done to intervene.

Many studies have shown that resveratrol has antioxidant, anti-inflammatory, and neuroprotective properties and can decrease the toxicity and aggregation of β-amyloid in the hippocampus of Alzheimer’s patients, promote neurogenesis, and prevent hippocampal damage (Gomes BAQ et.al., 2018). 

 β-amyloid is the main component of amyloid plaques found in the brains of people with Alzheimer’s.

Resveratrol also activates SIRT1 which plays a vital role in the growth and differentiation of neurons. SIRT1 is a protein which is considered a master metabolic regulator.

 Resveratrol is found in the skin of grapes, but also in other various plants. It is known as an antioxidant and got a lot of attention when a study on mice showed that resveratrol increased the lifespan of these animals in spite of being fed a high fat, high calorie diet
