Short-chain fatty acid PLUS (SCFA+) assay

Short-chain fatty acids (SCFAs) and medium-chain fatty acids (MCFAs) are important energy-supplying metabolites. They are also signaling molecules involved in the regulation of carbohydrate and lipid metabolism, as well as mediators of the gut microbiome-immune axis and the gut-brain axis. Aberrations in the metabolism of SCFAs and MCFAs can result in a wide range of disorders including diabetes, neurodegenerative diseases, and cancer. The combined analysis of SCFAs and MCFAs can provide crucial insights into the diet-microbiome-host interaction, energy homeostasis, and health status.

Short-chain fatty acid PLUS assay

The ideal triad for studying metabolic health and the microbiome

Short-chain fatty acids (SCFAs)

Microbial metabolites involved in metabolic health, energy metabolism, and immune balance

Branched-chain fatty acids (BCFAs)

Diet-based gut bacterial mediators of the gut-brain axis

Medium-chain fatty acids (MCFAs)

Energy carriers involved in insulin resistance and the gut-immune axis

SCFAs are important tissue-specific energy and signaling molecules

Besides an energy source, MCFAs exert tissue-specific metabolic regulatory functions
