Learn all about Glutathione
What is Glutathione?
Activate your body's master antioxidant with absorbable glutathione. Supports cell detox & skin health. Protect from within!
Benefits of Glutathione
- Acts as a powerful antioxidant, neutralising harmful molecules ('free radicals') and reducing cell damage ('oxidative stress')[ref]
"Glutathione levels might be a key indicator of cell health and aging. While standard oral supplements haven't worked well, newer delivery methods like liposomal glutathione show promise. For many, boosting the body's own production with precursors like N-acetylcysteine (NAC) and ensuring enough cofactors (like selenium) might be more effective than taking glutathione directly."
- Dr. Mark Hyman, Director of the Cleveland Clinic Center for Functional Medicine (source)
How to use Glutathione
Dosage
Liposomal glutathione: 250-1000mg daily. N-acetylcysteine (NAC) as an alternative to boost natural production: 500-3000mg daily.
Timing
Best taken on an empty stomach or between meals. Consistent daily use is recommended.
Notes
Standard oral glutathione isn't absorbed well. Liposomal forms (wrapped in fat), under-the-tongue delivery, or precursors like NAC are absorbed better ('higher bioavailability').
Who should take Glutathione?
- Individuals exposed to high levels of environmental toxins
- Those with chronic liver conditions needing extra support
- People experiencing significant cell damage ('oxidative stress') or chronic inflammation
- Individuals seeking skin brightening or anti-aging support
How does Glutathione work?
Glutathione protects cells in several ways. It directly neutralises harmful molecules ('reactive oxygen species') using its sulphur component. It helps enzymes turn harmful hydrogen peroxide into water. For detoxification, it attaches to toxins (especially in the liver) making them water-soluble so they can be flushed out. It also helps recycle other antioxidants like vitamins C and E, restoring them so they can keep working.
Frequently asked questions
Natural sources of Glutathione
Your body makes its own glutathione from amino acid building blocks. Diet plays a supporting role. Sulphur-rich foods (garlic, onions, broccoli, Brussels sprouts), asparagus, avocados, and spinach contain some glutathione, but it's poorly absorbed from food. Eating foods rich in the precursor amino acids (cysteine from whey protein/eggs, glycine, glutamic acid) helps your body make more. Selenium (a mineral) is also essential for glutathione activity.
Potential side effects & risks
Warnings
People with asthma should use caution (inhaled glutathione can trigger breathing issues). Not recommended during pregnancy/breastfeeding (limited data). Individuals sensitive to sulphur might react.
Side effects
Generally well-tolerated. Sometimes causes digestive upset, nausea, rash, or headaches at higher doses. Some notice an unpleasant sulphur smell/taste.
Interactions
May interact with drugs that suppress the immune system. Theoretically might reduce the effectiveness of some chemotherapy drugs. Use caution with drugs processed by the liver.
