Frequently Asked Questions

What percentage of glutathione is actually absorbed from supplements?

While exact absorption percentages aren't established, clinical trials demonstrate that both standard and liposomal oral glutathione can increase blood and tissue levels. Liposomal formulations show superior increases in blood glutathione markers compared to standard forms in controlled studies.

How long before I see skin lightening results from glutathione?

Clinical studies using 250mg daily doses typically show measurable melanin reduction within 12 weeks. Facial improvements often appear earlier than body areas, with individual response varying based on baseline skin tone and other factors.

What are the odds of experiencing side effects from glutathione?

Clinical trials report adverse events in only 1-5% of users at standard doses, primarily mild digestive symptoms. Studies show no significant difference in side effects between glutathione and placebo groups at commonly used doses of 250-1000mg daily.

How much does glutathione decline with age?

Age-related glutathione decline varies by tissue type and measurement method. MR spectroscopy studies show lower brain glutathione in older versus younger adults, with the magnitude varying by brain region. The pattern and extent differ across body systems.

What is the optimal daily dose based on research?

Clinical studies commonly use doses between 250-1000mg daily. Skin studies successfully used 250mg, while other applications have employed up to 1000mg. The optimal dose likely varies by individual factors and health goals, with most research supporting doses in this range.
