How Sight Guard Works

Energy Support for Long-Term Vision Health

Your retina is one of the most energy-demanding tissues in your body.

Every second, retinal cells convert light into electrical signals that travel through the optic nerve to your brain. That process requires constant ATP production, powered by mitochondria.
As we age, cellular energy production declines. NAD+ levels naturally decrease. Mitochondria become less efficient.
Sight Guard was formulated to support these foundational energy systems.*
The Challenge

Age-Related Cellular Energy Decline

Research shows that NAD+ levels decrease with age.

NAD+ plays a central role in:

  • Cellular energy production
  • Mitochondrial function
  • Oxidative balance
  • Cellular resilience
Because retinal and optic nerve cells have high metabolic demands, supporting energy metabolism may help maintain healthy function over time.*
The Pathway

The Cellular Energy Pathway

1
Light enters the eye
2
Retinal cells convert light to signals
3
Mitochondria produce ATP
4
Signals travel through the optic nerve
When mitochondrial efficiency declines, cells must work harder to meet energy demands. Sight Guard supports this pathway from the inside out.*
The Formula

The Ingredients Behind the Formula

Nicotinamide Riboside (NR)
NAD+ Precursor

A precursor to NAD+.

Studied for its role in supporting cellular NAD+ levels and mitochondrial function.

Supports healthy cellular energy metabolism.*

Calcium Pyruvate
Energy Metabolism

Involved in ATP production and cellular metabolic pathways.

Supports mitochondrial energy systems.*

CoQ10
Electron Transport

Essential to the electron transport chain.

Supports cellular energy production and antioxidant balance.*

Ginkgo Biloba Extract
Circulation Support

Studied for its role in supporting circulation and antioxidant activity.

Supports vascular health and oxidative balance.*

Lutein
Macular Pigment

A carotenoid naturally concentrated in the macula, the part of the retina responsible for central vision.

Supports macular pigment density and helps filter high-energy blue light.*

Provides antioxidant support for ocular tissues exposed to daily light stress.*

Mitochondrial Health

Why Mitochondrial Support Matters

Mitochondria are responsible for producing ATP, the molecule that fuels nearly every cellular process in the body.
The retina consumes more oxygen per gram of tissue than almost any other organ in the body.
Supporting mitochondrial function is a growing area of research in longevity and neuroprotection.

Sight Guard focuses on supporting the systems responsible for cellular energy and resilience.*
