What is glutathione IV therapy?
It is the intravenous administration of glutathione, the body’s own principal antioxidant. It aims to support cellular antioxidant defence and the liver’s detoxification processes. Sessions at IV Point take 20–30 minutes and are administered under observation, after an assessment by an anesthesiology specialist.
What Is Glutathione?
Glutathione (GSH) is a tripeptide made of three amino acids: glutamate, cysteine and glycine. Your body produces it itself, and it is found in nearly every cell.
It has three core jobs:
Antioxidant defence. It neutralizes free radicals and contributes to protecting cells from oxidative damage. This is why it is called the “master antioxidant” — it also plays a role in regenerating other antioxidants, such as vitamins C and E.
Detoxification. In the liver’s phase II conjugation step, it acts as the cofactor for the glutathione-S-transferase enzyme, taking direct part in making electrophilic substances and xenobiotics excretable.1
Cellular balance. It has a central role in regulating the cell’s redox balance.
Glutathione levels decline with age, and its consumption accelerates in states of increased oxidative load — alcohol, certain medications, smoking, chronic disease.
Why Intravenously?
It has long been known that oral glutathione is largely broken down in the digestive system. In a study of healthy volunteers, standard oral glutathione produced no significant rise in plasma glutathione levels; systemic bioavailability in humans was reported as negligible.2
Intravenous administration bypasses digestion and the liver’s first-pass metabolism.
A note: later studies with newer formulations — liposomal and sublingual — have reported partial absorption. So “oral glutathione is useless” would not be accurate; form and dose matter.
Its Effect on Skin: What Does the Evidence Actually Show?
You probably came to this page for this question. We want to answer it completely, because most of what circulates about it is either exaggerated or incomplete.
Where did the idea come from?
Interestingly, skin lightening emerged not as a planned effect but as an observation. In patients receiving intravenous glutathione for other reasons, lightening of skin colour was noticed. Today’s entire research field is built on that incidental observation.
What is the mechanism?
Glutathione’s effect on pigmentation is explained through direct and indirect inhibition of tyrosinase — the key enzyme in melanin synthesis — and a shift of melanin production from eumelanin to pheomelanin.3 So the mechanism is defined — the question is not whether a mechanism exists, but how well it works in the clinic.
The evidence, by route of administration
This is the critical part, and the part most sources skip. The three routes do not have the same level of evidence.
| Route | State of the evidence |
|---|---|
| Oral | Significant but variable reductions in melanin levels reported; side effects limited.4 |
| Topical (on the skin) | Good-level melanin reduction and improvement in skin texture reported; durability variable.4 |
| Intravenous (IV) | Claimed to act fast, but there are not enough human studies proving its effectiveness.3 No consensus standard dosing protocol exists either.4 |
Our position
Faced with this picture, our stance is clear:
We do not administer glutathione for skin lightening, and we promise no such result. Offering that as a service would mean selling a use that lacks evidence.
What we do is antioxidant support. Glutathione’s antioxidant and detoxification functions are well defined, and we ground the treatment there.
So will your skin look better? Your skin’s appearance mirrors your general condition — oxidative load, fluid balance, sleep, diet. Antioxidant support can contribute to that picture, and clients may describe their skin looking fresher after a session. But that is different from skin lightening, and we do not present it as a measurable promise.
In short: your skin may look fresher and more vital. Not whiter.
Why Must It Be Done Under Physician Supervision?
As with any intravenous treatment, an allergic reaction — though rare — can occur with glutathione, and when it does, it usually shows itself within the first minutes. In a properly run clinic this is not something to fear; it is a possibility that is prepared for — and that is the real reason physician supervision matters.
At IV Point:
- A physician assessment precedes the treatment; allergy history, chronic conditions and medications are reviewed
- You are observed throughout the infusion, with vital-sign monitoring
- Emergency response equipment is kept ready at all times
- The process is supervised by an anesthesiology specialist trained in emergency airway management and resuscitation
For a treatment people say “is done everywhere”, this is where the difference lies.
About the Formula
The treatment is planned individually after the pre-treatment assessment. Core components:
- Glutathione: the protocol’s main component
- Vitamin C: for antioxidant support and to slow the oxidation of glutathione
- Fluid and electrolyte support: sterile isotonic sodium chloride solution
Additional components such as alpha-lipoic acid are considered by the physician according to your picture.
Why aren’t doses listed here?
Doses are set individually; we do not publish a standard dosing chart. We would also point out: no consensus standard dosing protocol for IV glutathione exists in the literature either.4 The contents and doses to be used are explained to you in detail before the session.
Potential Benefits
- Support for antioxidant capacity — during periods of increased oxidative load
- Support for the liver’s detoxification processes — through its cofactor role in phase II conjugation1
- A contribution to regenerating other antioxidants — through its role in reactivating vitamins C and E
- An indirect contribution to skin appearance — not the primary goal
Effects vary from person to person. This treatment does not lighten skin colour, does not treat pigmentation, does not treat disease, and does not replace medical treatment.
Who Might Consider This Supportive Treatment?
- Adults wanting general antioxidant support during periods of increased oxidative load
- People with factors that increase oxidative load, such as smoking or heavy sun exposure
- People wanting to support their skincare routine from within
- People looking for general support during intense work periods
Note: if pigmentation spots bother you, the right address is a dermatology assessment. Melasma, sun spots and post-inflammatory hyperpigmentation are different conditions, each with its own treatments of proven effectiveness.
Who Is It Not Suitable For?
- Active liver disease — physician assessment is mandatory
- Kidney failure
- Pregnancy and breastfeeding
- Anyone receiving chemotherapy or radiotherapy — the effect of high-dose antioxidants on treatment effectiveness is debated; not administered without your oncologist’s approval
- Known allergy to any component, or a history of previous infusion reactions
- Known hypersensitivity to sulfur-containing compounds
Tell us about every medication and supplement you use before the treatment.
Possible Side Effects
- Temporary redness, tenderness or bruising at the IV site
- A temporary sulfur-like taste or smell (from glutathione — harmless)
- Dizziness or nausea (rare)
- Allergic reaction to a component (rare)
Rare as it is, that possibility is why the treatment is administered under medical supervision. You are observed throughout the infusion.
Before, During and After
Before: no need to fast. Be sure to tell us about your medications, chronic conditions, allergy history and any previous infusion reactions.
During: 20–30 minutes. You can rest seated, work or listen to music. You are under observation throughout.
After: no particular restrictions. If itching, a rash, shortness of breath or palpitations develop after the session, contact us immediately.
See a Dermatologist If You Notice These Skin Changes
Some lesions mistaken for pigmentation spots need a different kind of assessment. If a mole or spot shows any of the following, have a dermatologist look at it:
- Asymmetry — the two halves of the lesion don’t match
- Border irregularity — ragged or blurred edges
- Colour variation — more than one shade
- Diameter — larger than 6 millimetres
- Evolution — change in size, colour, shape or elevation
A lesion that bleeds, itches or doesn’t heal; a new dark line under a nail; a new, fast-growing spot — these should be assessed the same way.
