Glutathione and what it does

38 replies19 peopleMar 12, 2026☆ Follow
Summary

Does glutathione detox heavy metals and support immunity, and what dosing, forms, and combinations actually work?

Users report glutathione acts as an antioxidant that aids liver detox, immune function, skin tone, and migraine reduction. Oral glutathione is poorly absorbed so many prefer precursors like NAC or injectable forms; common doses range from 100-250 mg every other day up to much higher oral amounts. Some combine it with vitamin C and note site reactions or timing considerations with other compounds. Recent studies suggesting tumors can use glutathione create caution for some participants.

What this discussion establishesWhere people disagree

Whether glutathione promotes or merely feeds existing tumors; whether subQ or IM injections are preferable due to injection-site reactions

Still open

Optimal dosing, best form for bioavailability, and safe timing with other compounds like peptides or NAD

Nothing here is advice.

I have some questions about glutathione. Someone suggested it for detoxing heavy stuff and supporting the immune system. Can anyone confirm if that's accurate and what dose might be appropriate?

It works as a strong antioxidant that fights aging and cell damage. It helps the liver clear toxins and heavy metals. It supports immune cells against infections. It can lighten skin, protect energy-producing parts of cells, and ease oxidative stress tied to diabetes or heart issues.

Precursors taken by mouth are probably better. Glutathione itself doesn't enter cells easily because of its size. NAC raises glutathione inside cells, and adding glycine helps too. It's cheaper and likely more effective.

The benefits listed earlier seem complete. Dosing varies a lot in what I've read. I use 250 mg every other day myself, though amounts from 200 mg weekly up to 2000 mg appear online. Start low after checking what fits your plan. Adding vitamin C and E plus NAC is often suggested alongside.

Just a standard vitamin C and E supplement then?

ClearBeacon24archiveMar 13
↳ replying to @SteadyAlder49

I've been using 200 mg every other day.

Should it be taken before, during, or after peptide use?

I do mine first thing in the morning, then the other items half an hour later.

Any reason for waiting the thirty minutes?

QuietAlder25archiveMar 14

I inject 100 mg with vitamin C under the skin each morning. It cut my migraines by about seventy-five percent after someone recommended it over a year ago. When I run out of the injectable version I switch to capsules at 1500 mg daily, which works similarly even though absorption is lower.

I didn't know that. I've thought about trying it but I'm prone to injection site reactions. Are the capsules pricey?

SteadyQuill55archiveMar 14

Thank you. I'll look into it.

To clear endotoxins from the NAD and other item? Makes sense. I've been injecting both at the same time though not mixed in one syringe, but I might change that. Which version are you using?

ClearBeacon24archiveMar 15
↳ replying to @PatientSparrow94

Yes for the NAD timing, just to stay safe. I use a pharma-grade version along with ascorbic acid from the same source.

SteadyAlder49archiveMar 15
↳ replying to @BrightBeacon39

I take most things together in the morning and a few before bed. Spacing them out works for some people but I don't have the time or discipline. Endotoxins are probably not worse than other things I've used before.

Oral or injection? I have some but held off on injecting after reading negative comments.

SlowWillow17archiveMar 17

I'm going to add it to an IV drip tomorrow. If it works well I might get some and inject it myself under the skin or into muscle.

Subq never stung going in but the site stayed sore for a couple days. Switching to IM stopped that with no problems.

PatientSparrow94archiveMar 20
↳ replying to @ClearBeacon24

Do you prefer one version over the other? I got one on my first order and noticed the other lists the actual manufacturer while this one seems more generic.

CopperAlder51archiveMar 20

A study came out this week that might be worth checking. It suggests glutathione can work both ways.

CopperSignal27archiveMar 21

There are also rodent studies where blocking the enzyme that makes glutathione leads to lower long-term levels and longer lifespan. No clear reason yet.

I've done something similar for the past year. My labs showed fatty liver problems that cleared up after starting an injectable protocol with vitamin C. Glad it helped your migraines too. My skin also looks better and it seems to brighten it.

IronKettle49archiveMar 22

There are different factory versions and also pharma-grade ones distributed through various channels.

Typical. You start a health routine to avoid cancer and then a study like this pops up. It does so many good things but cancer always finds a way. Might be another thing to skip.

ClearBeacon24archiveMar 31
↳ replying to @PlainKettle50

The study doesn't say it causes cancer, just that cancer can use it to feed tumors. Same as with some other compounds. Did I miss something?

CopperSignal27archiveApr 1

New cancer cells probably form most days, especially as you age, but the immune system usually handles them. Anything that helps them grow could be a concern.

What NAC dose are you using? It bothers my teeth so I'm looking at capsules instead.

WarmSparrow81archiveApr 5

I'd like more details on S-acetyl glutathione versus liposomal. One is said to be the most bioavailable while regular reduced glutathione breaks down before it can work. There's also an unconfirmed claim that the acetyl form crosses the blood-brain barrier.

WarmWillow50archiveApr 5

The acetyl group is supposed to protect it during digestion so it stays stable when taken by mouth. Reduced glutathione gets broken down in the gut, which matches what you said. The blood-brain barrier part is interesting too. I bought some to inject so it's the reduced form since it won't face stomach acid.

That's encouraging, good to hear the migraine relief worked. My practitioner wants a high-dose vitamin C approach plus liver support for possible mast cell issues. I get near-daily headaches that are migraine-level but not severe with aura. This makes me want to try it. How much vitamin C do you use with it, and do you inject the C too?

QuietAlder25archiveApr 19
↳ replying to @GreenThistle10

I mix 1200 mg glutathione with a 500 mg ampule of injectable vitamin C and add sterile water. Everything comes in a kit. I dilute so that 50 units equals 100 mg. At that strength it usually doesn't sting under the skin.

GreenThistle10archiveApr 19
↳ replying to @QuietAlder25

Thanks, I just ordered some and will check the kit option next time.

LevelTimber64archiveApr 19
↳ replying to @GreenThistle10

Is it reconstituted with only sterile water? No bacteriostatic water? Just want to be sure I have it right.

I used purified water together with ascorbic acid and avoided bac.
