Bioavailable Resources refer to essential substrates, nutrients, or signaling precursors that have been successfully absorbed, metabolized, and made functionally accessible at the cellular level for immediate physiological processes. These are the resources the body can actually integrate into its functioning systems. They are the usable components of intake.
Origin
Rooted in pharmacology and nutrition science, “bioavailability” denotes the fraction of an administered substance that reaches systemic circulation and target tissues. In this context, it specifically emphasizes substrates critical for endogenous processes like steroidogenesis or protein synthesis.
Mechanism
Effective utilization hinges on intact gastrointestinal function and efficient hepatic conversion pathways to transform ingested materials into biologically active forms, such as cholesterol into required steroid hormones. If bioavailability is compromised, even adequate intake fails to support optimal endocrine output, demonstrating a functional bottleneck in resource delivery.
