Why Omega-3s May Help Aging Kidneys: It Comes Down to One Receptor
This study suggests omega-3 fatty acids may protect kidneys, though benefits likely depend on receptor activity that declines with age.
Scientists found that omega-3 fatty acids slowed kidney aging and fibrosis in mice, but only when a specific receptor called FFAR4 was working. This receptor is less active in older people and in those with chronic kidney disease. When researchers removed FFAR4 in mice, kidney aging got worse, which may explain why omega-3 trials sometimes give mixed results.
