Genotype-Guided Dietary Supplements in Precision Nutrition

Achieving adequate micronutrient status while avoiding deficiencies is a challenge for humans globally. As a result, many people turn to oral nutritional supplements (ONS) to correct suboptimal dietary intake. Advances in the fields of nutrigenetics and nutrigenomics have identified differences in response to micronutrient supplements based on genetic makeup, adding dietary supplement use to the clinician's toolkit in the era of precision nutrition.

As more and more health professionals participate in ONS prescribing, identifying and matching appropriate dietary supplements to individuals' genotypes is important to achieve optimal health benefits and micronutrient balance, while reducing adverse events and financial costs often associated with excessive ONS.
