N-Acetyl-Cysteine is an amino acid that has been researched heavily for its antioxidant and anti-inflammatory properties. NAC is primarily a building block for glutathione. Key clinical studies explore its role in respiratory health, vision support, liver function, aging, and anti-inflammatory properties.
As an antioxidant, NAC helps protect healthy cells by neutralizing free radicals before they can cause harm. It supports the body’s supply of cysteine, a key building block of glutathione, one of the body’s most important internal antioxidants. By helping restore glutathione levels, NAC strengthens the cell’s antioxidant defenses and helps clear reactive oxygen species, or ROS. NAC also has anti-inflammatory effects. In the early stages of immune activation, it may help reduce the release of cytokines, which are chemical messengers involved in inflammation. 1

Glutathione is a master antioxidant, meaning it can help neutralize a wide range of free radicals in the body. This article explains the roles glutathione plays in the body, focusing on why it matters for healthy aging. We review how glutathione supports the eyes’ natural defenses against oxidative stress. And, we discuss research linking lower glutathione levels with common vision concerns such as cataracts, glaucoma, and macular degeneration, along with a brief look at emerging research on glutathione’s role in cellular protein handling. It also covers practical ways to support glutathione through diet and supplementation.

When tiny plastic particles pollute the ecosystem, can they cause harm? If so, can you do anything? At Natural Eye Care, we have mined the research on the effects of microplastics and nanoplastics on human health. Read on to find out what they are, how they affect living organisms, and how to reduce your exposure.
Cataracts are a condition where the lens of the eye becomes cloudy. They are common among seniors. Symptoms include:

What is the relationship between brain health and eye health as we age? Our brains adapt and form new connections throughout our lives. Nutrition, lifestyle choices, and early detection play major roles in keeping the brain healthy, and the eyes. Find out about Natural Eye Care’s holistic approach to brain and eye health.
Our brains have an incredible ability to adapt and change as we age. Brain plasticity means that our brains can rewire themselves and form new connections, even as we get older.
At Natural Eye Care, we view vision health from a whole-body perspective. Eye studies can reveal how to manage the visual system. However, the health of the eyes is connected to overall health. The visual system requires as much as 25% of the nutrients we take into our bodies. The brain needs even more. How we take care of ourselves goes a long way in helping to preserve healthy vision. Personal care includes emotional balance, and lifestyle considerations such as eating a healthy diet, exercising regularly, and targeted supplementation.

Researchers have noticed that patients with severe or fatal covid-19 are usually deficient in the amino acid and powerferful antioxidant, glutathione.
In fact, some researchers feel that glutathione deficiency may be the Trojan horse of covid-19-related death.1
The latest Townsend Letter features co-owner of naturaleyecare.com Michael Edson, L.Ac., MS and his article, Underlying Causes and Natural Treatments for Alzheimer’s and Dementia.
The publisher’s discussion of Michael’s article also mentions that studies report that the Tdap (Tetanus, diphtheria, and pertussis) vaccination reduces the risk of dementia by 42% with similar results for flu and pneumonia vaccines. Both results may be due to reduced overall inflammation in the body.
Glutathione is rather amazing – low levels are biomarkers for various conditions and it is a “super antioxidant.”
Low levels of glutathione are linked to cataracts, macular degeneration, glaucoma, and brain neurodegenerative problems. The amount of glutathione in blood plasma is considered an overall indicator of the body’s antioxidant defense system.
Glutathione (GSH) is a super free radical fighter with the capacity to neutralize the full spectrum of free radicals. Normal metabolic activity creates free radicals, they can be destructive. They are missing an electron in their outer orbit and therefore try to steal one from a nearby healthy cell, rendering that cell dysfunctional.

What is so special about glutathione? This amino acid is considered a super antioxidant. It is one of the few nutrients that can neutralize the full spectrum of free radicals in the body. Free radicals are molecules missing an electron in the outer orbit; they ‘steal’ an electron from a healthy cell causing that cell to atrophy and die. Glutathione has an extra electron, binds with free radicals, and neutralizes them.
Glutathione is concentrated in the brain, supports the eye’s lens, retina/macula, cornea, detoxifies, and can be produced by the body — but production declines as we age and/or in the face of poor diet, environmental toxins, stress, trauma, some medications, infections, etc.

NaturalEyeCare™ started in 1999 to help the public and professionals learn about complementary care in eye disease treatment.
The information and recommendations we offer are based on over 30 years of peer review research and personal clinical experience which guides us in providing a valuable resource to our readers, customers and patients regarding maintaining healthy vision naturally.
We believe that vision health is intimately connected to overall mental, physical and spiritual health. Therefore we encourage people to look at their overall lifestyle and diet as part of keeping healthy vision and reducing the risk of eye disease onset. This includes diet, regular exercise, and management of daily stress. If one has health issues such as high blood pressure, a thyroid imbalance, any autoimmune disease and/or are on medication(s), these possible contributions to eye disease should considered when working with your health care professional.
Please do not hesitate to call us at 845.475.4158 with any questions and concerns.
