New research has shown for the first time that omega-3 in fish oil could “substantially and significantly” reduce the signs and symptoms of osteoarthritis.
Omega-3-rich diets fed to guinea pigs, which naturally develop osteoarthritis, reduced disease by 50 per cent compared to a standard diet, according to the University of Bristol study published in the journal Osteoarthritis and Cartilage.
The research is a major step forward in showing that omega-3 fatty acids, either sourced from fish oil or flax oil, may help to slow down the progression of osteoarthritis, or even prevent it, confirming anecdotal reports and ‘old wives’ tales’ about the benefits of fish oil for joint health.
Lead researcher Dr John Tarlton said there was “strong evidence that omega-3 influences the biochemistry of the disease, and therefore not only helps prevent disease, but also slows its progression, potentially controlling established osteoarthritis.”
Fish oil is far more effective than the flax oil based supplement, but for vegetarians flax oil remains a viable alternative.
Further studies are needed to determine the influence of omega-3 fatty acids on established disease in guinea pigs, and to confirm the effects in human osteoarthritis, said Dr Tarlton.
