lifestyle
2

Kynurenine pathway metabolite testing

Comprehensive monitoring of tryptophan metabolites including kynurenine to assess pathway activity and treatment response.

monitoring
3

Niacin supplementation

Vitamin B3 supplementation supports the kynurenine pathway downstream, potentially improving metabolic balance. Monitor for flushing and liver function.

medication

Additional treatment options

Tryptophan-balanced diet

Moderate tryptophan intake with attention to balanced protein sources. Tryptophan is a precursor to kynurenine through the indoleamine 2,3-dioxygenase pathway.

dietary

Vitamin B6 supplementation

Pyridoxal-5-phosphate supplementation supports kynureninase and other B6-dependent enzymes in the tryptophan-to-niacin conversion pathway.

complementary

Stress management and sleep optimization

Chronic stress and poor sleep can influence kynurenine pathway activity through immune activation. Stress reduction techniques support metabolic balance.
