New research has revealed that omega 3 and vitamin D do not help to prevent age-related macular degeneration (AMD).

A new study, which is the largest of its kind to date, has looked at whether supplements of vitamin D or omega-3 fatty acids reduce the risk of developing AMD or the condition progressing.

In a recent trial in the US, a group of more than 25,000 men and women, were given a daily supplement of both vitamin D and Omega 3, or a placebo, for an average of more than five years. The results showed that overall the supplements had no effect on the vision of the participants, whether they had AMD or not.  

Geraldine Hoad, research manager for the Macular Society, said: “In the past observational studies have suggested that higher intake of vitamin D and Omega 3 may be associated with lower risks of AMD. However, the evidence has always been limited. This latest trail is the best evidence to date that these two nutrients specifically, do not prevent someone from developing AMD.

“However while Vitamin D supplementation may not protect your vision, it is still recommended by the NHS for overall health – especially between October and early March when we do not get enough vitamin D from sunlight.”

Studies into the benefits of taking supplements for eye health are conflicting. It is widely agreed that if you eat a healthy diet, including at least five portions of fruit and vegetables a day, you should not need a supplement. In reality, most people do not eat the recommended amounts.
