Vitamin B12 powers your body in important ways, ranging from supporting the nervous system to helping with the production of red blood cells. The lack of this vitamin can therefore prove insidious. However, your vision could break the news of a vitamin B12 deficiency.
A medical institute Medanta explains that disturbed of blurred vision appear once the lack of B12 targets your optic nerve.
Medanta shares: “This happens when the deficiency causes damage to the optic nerve that leads to your eyes.
“The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.
“This condition is called optic neuropathy and treatment involving B12 supplements usually reverses the impairment.”
How to treat vitamin B12 deficiency
The course of action will depend on what’s causing the condition in the first place. So, treatments can vary based on what they need to target.
The most common options include injections or tablets to replace the missing B12.
There are also some good food sources of vitamin B12 like meat, salmon and cod, milk and dairy products as well as eggs.
As these are all animal-derived, vegan and plant-based diet followers might often struggle to reach the target for B12. But they can be aided by supplements, for example.
