Targeting tryptophan metabolism, specifically by inhibiting TDO or boosting de novo NAD+ synthesis, may extend lifespan and improve metabolic health in animal models.
Current research suggests that modulating tryptophan metabolism (e.g., boosting NAD+ synthesis) might improve metabolic health and potentially extend lifespan in animals. However, this is not yet a recommended human intervention due to potential risks like aggravated inflammation. Focus on healthy lifestyle factors that naturally support metabolic health.
Evidence from studies in Caenorhabditis elegans and rodents suggests that targeting Trp metabolism could extend lifespan... knockdown of tdo-2 in C. elegans increased lifespan with ~15%.
Why this rating
Based on animal studies (C. elegans, mice, rats) and observational data in humans, but no direct human lifespan extension trials.

More from this paper
- The kynurenine/tryptophan (Kyn/Trp) ratio in blood serves as a robust biomarker for the rate of physiological aging (inflammaging) and predicts age-related diseases and mortality.Good
- Activation of the kynurenine pathway via IDO/TDO enzymes during inflammation promotes immune tolerance and prevents hyperinflammation by depleting tryptophan and producing kynurenine, which activates the aryl hydrocarbon receptor (AhR) to drive regulatory T cell differentiation.Moderate
