Is LDL useful for Darmgesundheit?

Short answer: LDL (low-density lipoprotein) is not a direct marker for gut health. LDL is a blood lipid primarily used to assess cardiovascular risk. There is emerging research linking the gut microbiome to cholesterol metabolism – for example, certain gut bacteria produce trimethylamine-N-oxide (TMAO) from dietary precursors, which can influence lipid levels. However, using LDL as a proxy for gut health is not evidence-based. A gut microbiome test (like MyBody-X's) can reveal bacterial diversity and potential dysbiosis linked to digestive symptoms, but LDL alone does not provide meaningful information about gut function. The evidence for a clinically useful connection is weak (mechanistic at best). For assessing gut health, stool tests measuring diversity, inflammation markers (e.g., calprotectin), or specific pathogens are more relevant. LDL remains a cardiovascular risk factor. Always discuss results with a healthcare professional.
