Glutathione is often called “the master antioxidant,” but it’s also one of the most misunderstood supplements.
Some people know it for skin brightening, others for liver detox, and many are confused about oral vs liposomal vs IV glutathione.
So what is glutathione really used for and how should you take it safely?
What Is Glutathione?
Glutathione is a naturally occurring antioxidant found in every cell of the human body.
It is made from three amino acids:
-
Glutamic acid
-
Cysteine
-
Glycine
Your body uses glutathione to:
-
Neutralize free radicals
-
Support liver detoxification
-
Maintain immune function
-
Protect cells from oxidative stress
As we age or under stress, illness, pollution, alcohol, or poor sleep glutathione levels decline.
What Are the Benefits of Glutathione?
1. Powerful Antioxidant Protection
Glutathione works at the cellular level, helping reduce oxidative damage linked to aging, fatigue, and inflammation.
2. Liver Health & Detox Support
In Canada, glutathione is widely used to support:
-
Phase II liver detox pathways
-
Clearance of environmental toxins
-
Alcohol and medication metabolism
This is why glutathione is commonly paired with milk thistle or NAC.
3. Immune System Support
Glutathione supports:
-
White blood cell function
-
Immune response regulation
-
Recovery during physical stress
4. Skin Brightening & Tone Support
Glutathione helps regulate melanin production by:
-
Reducing oxidative stress in skin cells
-
Supporting a more even skin tone
Is Glutathione Safe to Take Daily?
Yes when used correctly.
Health conscious people typically tolerate glutathione well when taken orally at appropriate doses.
