What is the Origin of Bioavailable Cofactors?

The term combines the pharmacological concept of "bioavailability," referring to the degree and rate at which a substance is absorbed, with the biochemical term "cofactors," which are necessary for enzyme function. It is a concept central to clinical nutrition and orthomolecular medicine. This clinical focus on form recognizes that the body must be able to utilize a nutrient, not just ingest it.

What is the Mechanism of Bioavailable Cofactors?

Bioavailable cofactors, such as the active forms of B vitamins (e.g., methylfolate, pyridoxal-5-phosphate) or chelated minerals (e.g., zinc glycinate), bypass the rate-limiting steps of endogenous activation and absorption. This direct availability ensures that key metabolic enzymes, including those in the steroidogenesis pathway or the Krebs cycle, operate at peak efficiency, preventing functional nutrient deficiencies at the cellular level. This optimization is crucial for sustained endocrine function.

Bioavailable Cofactors

Meaning

Essential non-protein chemical compounds, such as specific vitamins and minerals, that are in a molecular form readily absorbed, transported, and utilized by the body’s enzymatic machinery without requiring extensive metabolic conversion. These cofactors are indispensable for thousands of biochemical reactions, including hormone synthesis and neurotransmitter production. Their high usability ensures that metabolic bottlenecks are avoided.
