The Active Ingredient Is: Pyridoxal 5'-phosphate (P-5-P)

P-5-P is the biologically active coenzyme form of vitamin B6, key for a bunch of metabolic and nervous system processes. This form is ready for your body without needing conversion, helping normal function in energy-producing pathways and neurotransmitter synthesis.

This formulation uses the active P-5-P form to support efficient utilisation of vitamin B6 in metabolism and neural support pathways. The product is produced in a facility dedicated to high-quality, hypoallergenic standards.

What Does Pyridoxal 5'-phosphate Do?

P-5-P takes part in neurotransmitter production and homocysteine metabolism, helping normal nerve function and cardiovascular-related metabolic processes. This aligns with EFSA-style claims about the role of B6 in metabolism and immune function.

Scientific insight from Dr. Abdullah at the University suggests P-5-P is crucial for neurotransmitter synthesis and energy metabolism, supporting normal physiological function.
