L-Glutathione

The article is quite positive on increasing Glutathione, and has a bibliography which the article claims shows up to 80% absorption from oral sources (see references 23-26). Some of the interesting points in the article are that glutathione decreases with age, except that centenarians have very high levels. In addition in mosquitoes, it seems that increasing Glutathione levels increases longevity. Also, it seems that in mice, acetaminophen use depletes glutathione, and that this effect is more pronounced in older mice.
Also, on the last two pages of linked PDF there are graphs showing intracellular concentrations after oral supplementation in HIV patients.
I have no way of knowing how valid all the above are, but it seems that increasing glutathione, either by the precursors or directly (or both) might be a good thing to do. Now it might be that the precursors such as NAC or whey might be more cost-effective, but I haven't come across any studies that indicate how much of a boost (for how long) is achieved by them.

Does anyone here supplement L-Glutathione by itself or along with NAC? I'm already taking NAC, and I also thinking about incorporating L-Glutathione into my regimen. What do you all think?
Thanks!

A great informative post however it went wrong

or lipoflow makes one too,
This is the most effective way to boost intracellular glutathione , be careful with it.

Oxidized Glutathione helps very well for Radiation Exposure such as a Nuclear Accident.
http://www.novelos.c..... shriners.pdf
In earlier nonclinical experiments conducted in the Russian Federation by the Russian Ministry of
Defense, groups of mice and rats were exposed to lethal levels of radiation. Treatment of animals
with NOV-002 (after exposure to radiation) resulted in a two- to three-fold increase in thirty-day
survival compared to the irradiated but untreated control animals. NOV-002 treated animals did
not experience severe neutropenia (loss of white blood cells used for fighting off infections) and
demonstrated significantly higher bone marrow cell counts than the control (bone marrow is the
source of white blood cells).

I made a trip to Barnes and Noble found it in "Biochemistry" Glutathione oxidized, GSSG or the (-OH) side of the reaction.
This isn't correct. -OH is the reduced form of a molecule and =O the oxidized form.
R-OH --> R(=O)H --> R(=O)OH
Alcohol --> Aldehyde --> Carboxylic acid
-------------------->
Oxidation
Or:
R-OH (sec. alcohol) --> R=O
Sec. alcohol --> ketone
-------------------->
Oxidation
But this isn't the case in glutathione. Here's the thiol (-SH) group the reduced form and the disulfide (-S-S-) the oxidized form.
Oxidized glutathione is two molecules glutathione that are linked together by a disulfide bridge between the two cysteine amino acids.
There aren't any -OH groups in glutathione or oxidized glutathione except for the -OH group that is a part of the -COOH group. The -OH from the -COOH group can't be oxidized.

This reaction you posted is overcomplicated.
It is just Glutathione that is on the oxidized or spent side of the reaction.
Prior to further breakdown into simpler molecules.
Very simple to integrate this into commercial use.

"Choose non-pasteurized and industrially produced milk that contains no pesticides, hormones, or antibiotics. Immunocal is a prescription bioactive non-denatured whey protein that is even listed in the Physician's Desk Reference." Can anyone recommend a brand other than immonucal for this...somewhere I read that Jarrows fits this criteria is that true? Otherwise I may try to get a prescription for this immunocal as my glutathione levels have been obliterated from the drug risperdal....

Glutathione as an oral whitening agent: A randomized, double-blind, placebo-controlled study.

Abstract
Abstract Objective: To determine whether orally administered glutathione, 500 mg per day for 4 weeks, affects the skin melanin index, when compared with placebo. Methods: This randomized, double-blind, two-arm, placebo-controlled study was set in the King Chulalongkorn Memorial Hospital, Bangkok, Thailand, a teaching hospital affiliated with a medical school. Sixty otherwise healthy medical students were randomized to receive either glutathione capsules, 500 mg/day in two divided doses, or placebo for 4 weeks. The main outcome was mean reduction of melanin indices measured at six different sites. Several secondary outcomes, including UV spots, were recorded by VISIA. Efficacies of glutathione and placebo were compared by ANCOVA with baseline values as co-variates.
Results: Sixty participants enrolled and completed the study. At 4 weeks, the melanin indices decreased consistently at all six sites in subjects who received glutathione. The reductions were statistically significantly greater than those receiving placebo at two sites, namely the right side of the face and the sun-exposed left forearm (p-values = 0.021 and 0.036, respectively). This was similarly reflected in the changes in the number of UV spots, as measured by VISIA. Both glutathione and placebo were very well tolerated. Conclusion: Oral glutathione administration results in a lightening of skin color in a small number of subjects. However, long-term safety has not been established and warrants more extensive clinical trials.

any more proof that l glutathione capsules get really absorbed? I'm looking for intracellular glutathion supplementsThis does seem to imply that oral glutathione is absorbed.

Does anyone know if this lypospheric gluthione really works?
http://www.livonlabs...pheric-gsh.html
and if this process to make it at home is legit ?

Glutathione is not orally bioavailable.
Is this still true 14 years later ?

Yes, or you need to take many grams for even a tiny bit to get absorbed.
The good news is that DMSO can get it through your skin.
Injections work as well.
As does intranasal delivery (although it gets broken down to its constituent amino acid l-glutamate which is neurotoxic)

Is is it ok?
If L-Glutathione does not work so why is it being sold and why are people making positive reviews on amazon ?

But what the link between DMSO and L-Glutathione ?I took :- N-Acétyle Cystéine (NAC)- Glycine.- L-Glutamine.
Is is it ok?

Lots of supplements sold that don't work, including GABA. That's just how it is.
Yes there are oral products that get absorbed but they're expensive and hard to get.
Just buy l-glutathione powder and dissolve it in DMSO or some skin cream and use it that way. Or get injections.

Where can i find intra musucular injection?

They are subQ as far as I know but Ebay, Alibaba and Amazon has it and they sell it for skin whitening

I saw this skin whitenning thing.
But cant find muscular injections so i will stick to NAC, Glycine., and L-Glutamine.

Skin whitening injections is just l-glutathione. It whitens skin so is sold for that purpose.
Alternatively I am mixing glutathione powder with dmso and using it that way on my skin. Really good for skin quality and it goes systemic.
