Glycine + N-Acetyl Cysteine Supplementation Increases Lifespan

TL;DR

Glutathione decline with age, but supplementing with glycine and n-acetyl cysteine can restore levels and improve health outcomes in older adults.

Transcript

glutathione declines during aging to illustrate that point let's take a look at data from three different studies so first when looking at glutathione gsh on the y-axis plotted against age starting from 21 year olds up to older than 61 we can see a 50 glutathione reduction during aging similarly in study number two again glutathione on the y axis p...

Key Insights

• 🥺 Glutathione levels decline during aging, leading to reduced antioxidant capacity and increased oxidative stress.
• 🧓 Supplementing with glycine and n-acetyl cysteine can restore glutathione levels and improve various health outcomes in older adults.
• 🤕 Glycine and cysteine levels decline with age, making supplementation important for glutathione restoration.
• 💪 Restoring glutathione levels improves oxidative stress, inflammation, insulin resistance, mitochondrial function, body composition, muscle strength, exercise capacity, and cognition.
• ✋ Centenarians have higher glutathione levels compared to individuals who are 30 years younger.
• ✋ Maintaining high levels of glutathione may be important for longevity.
• 😀 Glycine and n-acetyl cysteine supplementation extends lifespan in mice.

Questions & Answers

Q: How does aging affect glutathione levels?

Glutathione levels decline during aging, leading to reduced antioxidant capacity and increased oxidative stress.

Q: Can restoring glutathione levels improve health in older adults?

Yes, supplementing with glycine and n-acetyl cysteine can restore glutathione levels and improve various health outcomes in older adults, including reducing oxidative stress, inflammation, and improving mitochondrial function.

Q: What are the benefits of glycine and n-acetyl cysteine supplementation in older adults?

Supplementation with glycine and n-acetyl cysteine improves body composition, muscle strength, exercise capacity, cognition, and reduces markers of endothelial dysfunction and insulin resistance.

Q: Do centenarians have higher or lower glutathione levels?

Centenarians have relatively higher glutathione levels compared to individuals who are 30 years younger, suggesting that maintaining high levels of glutathione may be important for longevity.
