Micronutrients & recovery

A three-week ketogenic diet shifts tryptophan metabolism to increase kynurenic acid and decrease quinolinic acid, potentially promoting mitochondrial protection and reducing neuroinflammation.

Following a ketogenic diet may shift your body's processing of tryptophan away from potentially neurotoxic byproducts (quinolinic acid) toward protective ones (kynurenic acid). This suggests a potential neuroprotective benefit of long-term ketosis.

Urine analyses... revealed changes to the tryptophan pathway depicting reduced quinolinic acid (-13.46% ± 6.12%, p = 0.0478) and elevated kynurenic acid concentrations (+10.70% ± 4.25%, p = 0.0269).
