Micronutrient Absorption

Meaning

Micronutrient absorption is the physiological process by which the small intestine takes up essential vitamins, trace minerals, and other necessary cofactors from ingested food and supplements into the bloodstream. This process is highly regulated and involves complex transport systems, carrier proteins, and passive diffusion across the intestinal epithelium. Efficient absorption is fundamental for providing the necessary substrates for all endocrine and metabolic pathways.
