Daily supplementation with GrandFusion^® improves memory and learning in aged rats

Area of Science:

• Gerontology
• Neuroscience
• Nutritional Science

Background:

• Aging is associated with declines in motor function and cognition.
• Oxidative stress, inflammation, and reduced neurogenesis contribute to age-related deficits.
• Fruit and vegetable extracts contain antioxidants and anti-inflammatory compounds that may counteract these changes.

Purpose of the Study:

• To investigate the impact of GrandFusion® (GF) extract supplementation on age-related deficits in aged Fisher 344 rats.
• To determine if GF can attenuate or reverse declines in movement and cognition.
• To explore the underlying mechanisms, including oxidative stress, inflammation, and neurogenesis.

Main Methods:

• Aged Fisher 344 rats were supplemented with GF extract for 4 months.
• Motor performance and cognitive functions were assessed.
• Levels of oxidative stress, inflammation, neurogenesis, Nrf2, and antioxidant expression were measured.

Main Results:

• GF supplementation significantly improved motor performance and cognitive functions in aged rats.
• A reduction in oxidative stress and inflammation was observed.
• Enhanced neurogenesis, Nrf2, and antioxidant expression were noted.
• GF extracts demonstrated significant augmentation of memory and learning.

Conclusions:

• GrandFusion® (GF) extract supplementation effectively attenuates age-related deficits in motor and cognitive functions.
• GF may exert its beneficial effects by modulating antioxidant enzymes, signaling pathways, and reducing oxidative stress and inflammation.
• These findings support the consumption of fruit and vegetable extracts for promoting healthy aging.
