Can N-Acetyl-Cysteine Support Cataracts, Retinitis Pigmentosa, Dry Eye & Macular Degeneration?

Broccoli soup is high in N-Acetyl-Cysteine.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

Antioxidants, Eye Disease and Oxidative Stress

antioxidant foodsThe links between antioxidants and vision health are strong. Antioxidants are the antidote to oxidization. Normal metabolism creates free radicals. These are atoms that lack an electron. Free radicals roam about the body, scavenging electrons and stealing electrons from healthy cells.  This results in permanent damage to these afflicted cells which ultimately can result in disease. Significant research has shown that antioxidants protect against this cellular damage and are essential for maintaining health. The eye is especially vulnerable to free radical damage. Therefore, providing the body with sufficient antioxidants

Diminished Cognitive Function in Elderly Linked to Homocysteine

older cognitive function Homocysteine is an amino acid that can be measured with a simple blood test. The study, which appeared in the Journal of Affective Disorders in August 2013, studied 358 people aged 50 and up who had symptoms of depression.

They gave the subjects cognitive tests that looked at immediate and delayed memory, as well as global cognitive performance. They measured

Elevated Cysteine Levels May Be Important Indicator for Future Heart Disease

In a study of more than 1,200 people undergoing cardiac imaging at Emory because of suspected heart disease, people with high levels of cysteine in the blood were twice as likely to have a heart attack or die over the next few years. Cysteine could be a valuable marker of…

Increased Homocysteine Levels in Tear Fluid of Glaucoma Patients

A research study shows that people with open-angle glaucoma (OAG) had significantly higher levels of homocysteine (Hcy) levels in their tear fluids. Patients with open-angle glaucoma who also had dry eye disease had significantly higher Hcy levels both in tear fluid and plasma than OAG patients without dry eye disease.

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.
