Nutrient Substrates

Meaning

Nutrient Substrates are the fundamental chemical compounds derived from the systematic digestion and absorption of the three primary macronutrients—carbohydrates, proteins, and fats—that serve as the essential raw materials for energy production and the necessary biosynthesis of all complex biological molecules. These foundational substrates primarily include glucose, amino acids, and fatty acids. They collectively form the molecular foundation upon which all physiological processes, including complex hormone synthesis, efficient tissue repair, and immune function, are built and sustained. The continuous, regulated, and balanced supply of nutrient substrates is absolutely non-negotiable for maintaining systemic metabolic homeostasis.
