Narrative review without systematic search or meta-analysis
PubMed 31484368 · doi:10.3390/nu11092073
What was done
This narrative review synthesizes human clinical evidence examining dietary and nutritional strategies—including amino acids, vitamins, minerals, phytochemicals, and whole foods—to support glutathione levels and redox balance, while evaluating the modifying role of genetic variation.
What was found
The abstract reports no quantitative values, effect sizes, or study counts. It notes qualitatively that nutritional interventions can influence circulating glutathione levels, but clear causal relationships between glutathione status and disease risk or clinical outcomes have not been established. It also highlights that individual genetic variation influences both baseline glutathione status and response to dietary interventions.
Why it matters
Summarizes potential non-pharmacological approaches to support antioxidant defense and detoxification pathways, highlighting the need for personalized approaches rather than generic supplementation.
Limits
The paper is a non-systematic narrative review. The abstract provides no data, trial characteristics, dosages, or effect sizes. Causal health benefits of dietary-induced glutathione changes remain unconfirmed.
