Could vitamin B3 play a role in protecting the optic nerve in glaucoma?
It’s an area of research that is attracting increasing attention.
Glaucoma treatment has traditionally focused on lowering eye pressure, but researchers are also exploring whether we can protect the optic nerve itself in other ways.
Early research into vitamin B3, also known as niacin, is showing some interesting potential. However, it’s important to be clear that it is not a replacement for your prescribed glaucoma treatment.
There is still much more to learn, but it’s certainly an area we’ll be watching closely.
If you have glaucoma, always speak to your ophthalmologist before adding supplements or making changes to your treatment.
