Could NAD+ Help Protect Your Vision? A Look at the Science Behind Eye Ageing and Cellular Repair
As we age, many of us notice changes in vision — from reduced clarity to difficulty seeing in low light. For some, these changes are linked to age-related macular degeneration (AMD), a condition that affects the part of the eye responsible for sharp, central vision. While genetics and lifestyle factors play a role, a growing body of research is exploring how NAD+, a naturally occurring coenzyme, could support eye health at a cellular level.
At Dr George Wellness, we follow the latest science closely to offer the best advice and treatments that support natural ageing and wellbeing — including NAD+ therapy.
What Is NAD+?
NAD+ (nicotinamide adenine dinucleotide) is a vital coenzyme found in every cell of the body. It plays a key role in:
Energy production (mitochondrial function)
Cellular repair and regeneration
Inflammation and oxidative stress reduction
DNA repair
As we age, NAD+ levels naturally decline — a process thought to contribute to fatigue, slower recovery, and increased susceptibility to age-related diseases, including those that affect the eyes.
The Link Between NAD+ and Eye Health
Recent studies have started to explore how boosting NAD+ levels may protect against vision loss, particularly from AMD. Here’s what the science is telling us so far:
1. Retinal Cells Are Highly Metabolic
The retina — especially the macula — has one of the highest energy demands of any tissue in the body. This makes it particularly vulnerable to mitochondrial dysfunction, which is closely tied to NAD+ depletion.
2. NAD+ Supports Mitochondrial Function
Declining NAD+ levels contribute to mitochondrial ageing, which in turn leads to retinal stress and cell death. Research shows that restoring NAD+ levels may improve mitochondrial health and protect retinal cells from damage.
3. Early Studies Are Promising
A 2020 study published in Cell Reports showed that increasing NAD+ levels in mice protected retinal cells from degeneration, helping preserve visual function.
Other preclinical trials have demonstrated that NAD+ precursors may prevent retinal thinning and reduce oxidative stress in models of age-related eye disease.
While human trials are still in the early stages, the evidence from animal studies provides a strong rationale for further investigation.
NAD+ Injections: A Targeted Approach
Oral supplementation with NAD+ precursors is one option, but injections are gaining popularity due to their direct, high-bioavailability delivery. For those looking to support overall cellular health — including eye function — NAD+ injections may offer:
Faster replenishment of depleted levels
Improved absorption, especially in individuals with gut issues
System-wide support, not limited to eye health alone
That said, while promising, NAD+ therapy should be seen as part of a broader strategy — not a standalone fix.
Should You Consider NAD+ for Eye Health?
If you have a family history of AMD, are experiencing early signs of vision decline, or are interested in proactive ageing support, NAD+ may be worth discussing with a qualified practitioner.
At Dr George Wellness, we offer personalised assessments and NAD+ therapy tailored to your unique needs — supporting your wellbeing at a cellular level.
In Summary
NAD+ is a powerful coenzyme with the potential to support eye health by enhancing energy production, reducing oxidative stress, and promoting cellular repair. While human research is still developing, early results are promising — and NAD+ injections may be a valuable tool in the fight against age-related vision loss.
