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

Is TUDCA a Promising Supplement For Vision Health?

Seniors playing cardsIf you’ve been diagnosed with an eye condition later in life, you’ve probably noticed that most “eye health” conversations focus on vitamins.1 Those can be important, but researchers are also exploring a different strategy: helping retinal cells survive stress.2

Can Stem Cell Therapy Help with Glaucoma, Macular Degeneration and Other Eye Diseases?

Representation of stem cells.
Stem cell research is transforming the field of vision care and bringing fresh hope to those affected by a wide variety of eye conditions. Scientists are making strides in everything from restoring sight for people with corneal damage to finding new ways to replace or repair cells lost to diseases like macular degeneration and glaucoma. Although most of these treatments are still being tested, the advances so far are both promising and inspiring. In this article, we explore how stem cell therapy works for various eye conditions, highlight the different types of stem cells used in vision research, and summarize the latest breakthroughs for diseases such as age-related macular degeneration, glaucoma, and dry eye syndrome. We also touch on the important considerations and safety issues involved with these emerging treatments. And, we share practical lifestyle tips that can support your eye health alongside the latest scientific advances.

Retinal Cells Rewire to Preserve Vision in Retinitis Pigmentosa

Retina cross-section diagram showing retinal cells - rods and cones - that have been found to rewire themselves. Retinitis Pigmentosa is a progressive eye disease that has long been associated with gradual vision loss and limited treatment options. Affecting about one in every 4,000 people, Retinitis Pigmentosa (RP) is marked by the degeneration of the retina’s photoreceptor cells—first the rods, which are responsible for night vision, and then the cones, which enable us to see in daylight and color. While the genetic complexity and slow progression of RP have posed challenges for patients and researchers alike, recent discoveries are offering new hope. Exciting new research reveals that the retina may have an unexpected ability to adapt: certain retinal cells can rewire themselves in response to degeneration, potentially helping to preserve vision even as the disease advances.

NMN (Nicotinamide Mononucleotide): The New Anti-Aging Nutrient?

nicotinamide mononucleotide NMN anti-aging nutrientIs it possible that NMN – nicotinamide mononucleotide – is an anti-aging nutrient? This chemical occurs naturally in the body, but levels drop in seniors. Researchers are finding that taking NMN supplements appears to have benefits. How does NMN work? What does it do? And, could seniors slow down the aging process by taking it?

Microcurrent Stimulation for Eye Disease (and more)

microcurrent stimulationMicrocurrent Stimulation treatment protocols are designed to help people with retinal disease. MCS works by supporting nourishment and healing to the back of the eyes as well as possibly some cell regeneration. Retinal tissue is easily the most complex tissue in the entire body, and we tell people that they need to commit to regular treatment for a year, because it may take up to a year before they first see results, though benefits may be seen much sooner.

A number of research studies have suggested that daily use of specific microcurrent stimulation helps promote retinal (as well as optic nerve health) in 3 different ways:

Macular Degeneration Glasses May Restore Vision: Pixium Vision’s Bionic PRIMA System Sees Improvements

pixium implant glasses for better visionPeople with vision loss due to retinal disease may be able to use a bionic  system to improve sight in the near future. Pixium Vision is running a feasibility study on is PRIMA System, and they got better-than-expected results. The study is on patients with dry Age-Related Macular Degeneration. Currently, medical science cannot restore vision in those with retinal dystrophies. The PRIMA System may lead to vision restoration for patients with Macular Degeneration, Retinitis Pigmentosa and other retinal diseases.

Retinitis Pigmentosa Gene Editing Studied on Human Embryos

gene editing fetus

The genetic eye disease Retinitis Pigmentosa is the target of gene editing research on human embryos by Dr. Dietrich Elgi at Columbia University. National Public Radio reported on this research1 shortly after a Chinese scientist announced he had created the world’s first two gene-edited babies.2 Both scientists use the CRISPR tool to genetically modify human embryos. However, the experiments at Columbia are for research purposes only. These embryos are destroyed within one day for study.
