Digestive Health – Inquis Clinical Research

Digestive Health

As research continues to emerge from the scientific community, the effects of digestive health on a variety of health outcomes are becoming increasingly apparent. Our research will help you stand out in the growing area of digestive health research.

Areas of Expertise

As microbiome research continues to dominate clinical nutrition research and new connections are constantly being made between microbiome composition and long term health markers, INQUIS Clinical Research is well-equipped to design and execute your clinical trial related to the microbiome. We have experience designing and executing acute studies to detect changes in microbiome composition, as well as long term studies that examine health indicators with shifts in microbiome populations, in addition to experience studying both prebiotics and probiotics and their effects on microbiome populations.

Determining whether a food or ingredient is digested can be established by appearance of glucose in the blood and the stimulation of insulin response. Our team of researchers is experienced in determining digestibility, as well as bioavailability and bioequivalency.

At INQUIS Clinical Research, our team of researchers can develop and execute both acute and long term research study designs to determine the gastrointestinal tolerance of foods and ingredients, sweeteners and fibers.
