Indolpropionic acid (IPA) is a microbial metabolite derived from the amino acid tryptophan. It is recognised for its antioxidant properties and plays a protective role in gut barrier integrity and glucose metabolism. Higher levels are generally associated with a balanced gut microbiota and a healthy intestinal environment. Low concentrations may indicate reduced microbial diversity, altered tryptophan metabolism, or increased oxidative stress.
Low IPA levels may indicate reduced microbial diversity, impaired tryptophan metabolism, or increased oxidative stress. This can be linked to weakened gut barrier integrity, heightened inflammation, or disrupted glucose regulation.
Testing IPA is beneficial for individuals interested in gut health, antioxidant levels, or metabolic balance. It can offer valuable insights for those experiencing digestive problems, chronic fatigue, insulin resistance, or inflammatory conditions.
IPA production depends largely on gut microbiota composition and dietary tryptophan availability. A low-fibre diet, dysbiosis, inflammation, or oxidative stress can reduce IPA formation. Conversely, a diverse and balanced gut flora supports its synthesis.
Yes. Supporting microbial diversity through a fibre-rich diet, fermented foods, and antioxidant intake can promote healthy IPA production. Reducing inflammation and maintaining balanced tryptophan metabolism also help sustain optimal levels.
