Krill is a type of small crustacean that lives in the world’s oceans. Extracts from certain species of Antarctic krill are high in omega-3s, which support brain function and are essential components for healthy cell membranes.
According to scientists, krill oil can help fight aging. Previous studies have shown that krill oil can extend the lifespan of one type of worm (nematode) by about 4 days.
In the new work, the scientists found that krill oil protected dopaminergic neurons from age-related degeneration, reduced alpha-synuclein aggregation, and improved dopamine-dependent cognition and behavior in laboratory models of Parkinson’s disease.
“Krill oil protects dopaminergic neurons from aging-related degeneration. It rearranges various gene expression programs that contribute to the reduction of several signs of aging. Collectively, krill oil rewires global gene expression programs and promotes healthy aging by reversing multiple signs of aging, offering directions for further preclinical and clinical research,” the researchers conclude.
