Glutathione

Glutathione (GSH) is a rather special antioxidant - it is known as a super antioxidant because it neutralizes the full range of free radicals. It provides essential support for the brain, optic nerve, lens, cornea, retina/macula, and the mitochondria within cells. It also performs detoxification duties. It is made up of three amino acids: cysteine, glycine and glutamic acid and helps to move those amino acids through the cell wall. It enhances functioning of other nutrients such as vitamin C, vitamin E, alpha lipoic acid, and CoQ10

Glutathione

Vision Support

Supports lens health For clear unclouded vision, the lens needs a lot of glutathione and vitamin C. Both nutrients are deficient in people with cataracts.1 Glutathione also helps sugar and protein molecules from binding together. This process known as glycation occurs as a result of aging and contributes to cataract development.

Supports retinal health GSH also helps protect retinal cells from damage. Patients with macular degeneration (AMD) have 58% less glutathione than healthy patients.2 It protects pigmented cells (the internal sunglasses) from oxidative damage by a particular type of fat (a 4-hydroxynonenal type). Taken in early stages of AMD, glutathione protects the retina from neovascularization, the development of extra blood vessels.3

Detoxification Glutathione contains sulphur which sticks to free radicals and heavy metals.4 This body chemical has sulfur, which sticks to free radicals and heavy metals in the body. This capacity is helpful in protecting the gut, kidneys, lungs, and possibly diabetes. In other words, it helps 'take out the trash.'5

Supports brain health Although glutathione is found throughout the body it is most concentrated in the brain. The brains of patients with neurodegenerative conditions, such as Parkinson's6 and Alzheimer's disease7 are deficient in glutathione. Researchers have found that when GSH is depleted in the hippocampus regions of an elderly person they suffer mild cognitive impairment present in the earlier stages of AD.8 On the other hand, elderly people with high levels of glutathione have better physical health overall.9

Glutathione in Our Bodies

Glutathione can be created by the liver if it also has ample supplies of selenium, vitamin C, n-acetyl-cysteine, glycine and glutamine. But as we age we begin to be low on GSH. Alpha lipoic acid, milk thistle extract and turmeric also boost its production in the body. We can also increase our glutathione levels with exercise.10

But poor diet, toxins, pollution, stress, aging, certain medications, infections, trauma, and radiation all reduce glutathione levels. Thus our cells are more vulnerable to damage from oxidization, infections, free radicals, and even cancer. Lack of glutathione can overload the liver, hampering its ability to detoxify the body. Excessive alcohol will reduce glutathione levels.

Good food sources include: sulfur rich foods such as cruciferous vegetable (broccoli, cauliflower, brussels sprouts, kale, watercress, mustard greens), garlic, onions, shallots, avocado, spinach, okra, whey.

Glutathione is best taken sublingually intraorally as it is not well absorbed through capsules or tablets. Glutathione is not absorbed well taken in capsule or tablet form. Sublingual dosages will typically be lower because they are absorbed 5-10 times more efficiently than capsules or tablets.

Best glutathione supplement

The glutathione product that we recommend is ACG Glutathione Spray. This oral spray delivers glutathione with the best possible absorption.

We include ACG Glutathione Oral Spray in a number of discount vision support packages:

For the optic nerve: Optic Nerve Support Package B.

For the lens: Can-C Eyedrops plus ACG Glutathione Package 1G, Advanced Lens Support Package 1 (3 mo supply.

For the cornea: Corneal Support Package 2
