Glutathione Helpful for Covid-19

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

Gut Microbiota, Vision, and Mental Health

gut microbes and dietDid you know that how well your gut works is directly related to your healthy vision and your healthy brain?

Healthy gut microbiota function is linked to normal central nervous system (CNS) function. The microbiota is defined as all microorganisms in a particular location, such as the GI tract, and their respective genetic material. The microbiome is initially developed transmission through the placenta, amniotic fluid, and meconium. The human gut microbiota comprises more than 100 trillion microorganisms associated with multiple functions, from nutrient metabolism to protection against pathogens.

Cardiovascular Disease Linked to Eye Disease

An eye exam can reveal disease

People with cardiovascular disease may be at a higher risk of developing certain eye diseases including macular degeneration, retinopathy, retinal bleeding, a retinal vein occlusion, and blurred vision.

Why is heart disease linked to eye disease?

Good vision requires, among other factors, adequate blood circulation, and normal blood pressure. The eyes have a network of tiny blood vessels, each no wider than a strand of hair, which supply blood to the retina, the light-sensitive tissue at the back of the eyeball.

Natural Eye Care Michael Edson’s Alzheimer’s Article in the Townsend Letter

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.

Glaucoma, IOP, and Herbal Extracts

 glaucoma aging seniors.The most common form of glaucoma is “open-angle” glaucoma, where the eye pressure or IOP remains higher than normal (typically 8-20 mm Hg). Eye doctors also look at changes in peripheral field typically measured with a visual fields test and any changes in the optic nerve such as optic nerve thinning or increased cupping. Ocular hypertension is diagnosed when IOP is higher than normal but there as no signs of glaucoma. In addition glaucoma can occur without high IOP, “normal or low tension glaucoma.”

Mesozeaxanthin: Star of Macular Carotenoids

carotenoid supplements and foodsMesozeaxanthin, less well-known than lutein and zeaxanthin, is the most powerful antioxidant of the threesome, but the combined trio presents the most potent protection for the eye than any of the three carotenoids alone.1  Out of all of the roughly 7000 carotenoids known in nature, it is these three that are found in great concentrations in the macula, the key part of the retina, responsible for central vision.

Melatonin: More than a Sleep Aid

What is Melatonin?

melatonin and sleepingMelatonin is a hormone primarily released by the pineal gland at night, and has long been associated with control of the sleep–wake cycle. It is typically taken at night before bedtime as a supplement. In addition to melatonin’s application as a sleep aid, this supplement can also be used for lowering eye pressure — such as in cases of open angle glaucoma or glaucoma suspects.  Research shows melatonin may also protect the eye’s macula by supporting the functioning of the mitochondria, the tiny “batteries” in each cell. Alzheimer’s disease appears to be linked to poor quality sleep and melatonin production; therefore, melatonin may prove to be a useful supplement and research is underway. Keep reading for details plus information about supplements available on this website.

Glutathione is a Super-Antioxidant

glutathione spray supplementGlutathione 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.

Zeaxanthin and Lutein Save the Eyes and Improve Brain Circulation

corn with lutein

The antioxidants lutein and zeaxanthin help keep the eyes healthy. A new study has found that these nutrients also improve the circulation of blood to the brain. Seniors experience gradual cognitive decline. A recent study showed that taking enough of these antioxidants halted cognitive decline. Research supports the idea that nutrition has a direct impact on the brains and eyes throughout one’s lifespan from infancy (breast milk contains lutein) to old age.1

Astaxanthin: Carotenoid with a Difference

salmon mealThe lowly microalgae in the ocean produce astaxanthin for their protection against environmental stressors and light.  Fish and crustaceans consume microalgae and retain the bright red color that we see in salmon, sea trout, shrimp, and krill.

When we enjoy savory salmon, the benefit of the astaxanthin that it contains extends to our vision, brain, circulatory system, immune system, etc., but with a difference. It provides significantly greater antioxidant protection (10x to 100x more) than other antioxidants.1 2 3

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.
