Nutrient Absorption Genes

Meaning

Nutrient Absorption Genes are a collection of polymorphic genes whose specific variants dictate the efficiency and capacity of the gastrointestinal tract to uptake and transport essential vitamins, minerals, and macronutrients across the intestinal barrier. Polymorphisms in these genes can lead to suboptimal serum levels of vital micronutrients, even with adequate dietary intake, directly impacting cellular function and hormonal synthesis. Clinical assessment of these genes allows for the precise tailoring of nutrient forms, dosages, and delivery systems to overcome genetically determined absorption inefficiencies. This is a fundamental aspect of nutrigenomic practice.
