Powerful Antioxidant May Improve Memory for Individuals With Cognitive Decline
A study published in the British Journal of Nutrition, recently found that supplements containing the antioxidant oligomeric proanthocyanidins (OPCs) can improve memory in mice with age-related cognitive decline.
Researchers from the University of Toyama in Japan and Pusan National University in South Korea engineered the mice to mimic the memory loss and decreased cognitive function that is seen in humans as they age.
Half of the mice were then supplemented with OPCs for five months, while the other half received no supplementation. After the five month period, the group that received the OPC supplements performed better on a number of cognitive tests including a Morris water maze, object location and object recognition tests.
The researchers also found that the antioxidant supplements appeared to protect the brain from damage that occurs naturally due to aging.
OPCs are usually derived from a combination of grape seed, red wine and/or pine bark extracts and have been shown to be up to 20 times more powerful than vitamin C.
While cognitive function is known to decline naturally as we age, accelerated decline is associated with an increased risk of dementia and Alzheimer's disease.
More and more dietary approaches for improving brain health are being discovered every day, which may help combat the soaring rates of Alzheimer's occurring as a result of our aging population.
One of the most studied dietary brain boosters are omega-3 fatty acids, which are found naturally in oily fish and can also be taken as a supplement.
Salmon, mackerel, lake trout and albacore tuna all have very high Omega-3 levels. If you opt for a supplement, be sure that it is a quality supplement high in DHA and EPA and certified for purity.
