Nutrient absorption enhancer

"Nutrient absorption enhancer" refers to any agent or compound that improves the uptake (bioavailability) of nutrients or drugs from the gastrointestinal tract or other absorptive surfaces. These may function by increasing membrane permeability (transient opening of tight junctions, disrupting lipid bilayers), forming complexes that facilitate transcellular transport, inhibiting intestinal or hepatic enzymes that degrade nutrients, stimulating transporter activity, or modifying the gut microenvironment (such as luminal pH or microbiota activity). Examples include natural compounds like piperine (from black pepper), pharmaceutical excipients such as salcaprozate sodium (SNAC), surfactants like sodium caprate, and nutrients such as ascorbic acid (which enhances iron absorption). The concept is used in both drug development and nutrition science to increase the oral or transdermal effectiveness of poorly absorbed compounds. However, "nutrient absorption enhancer" is a functional class, not a discrete molecular drug target.
