The Active Ingredient Is: Vitamin B6 (Pyridoxal 5'-phosphate)

Vitamin B6 in its active form, pyridoxal 5'-phosphate, is a water soluble nutrient essential for normal nervous system function and energy metabolism. This form does not require liver conversion, offering high bioavailability in supporting daily physiological processes.

This formula uses pyridoxal 5'-phosphate as the primary active ingredient, with supporting excipients to deliver a stable vegetarian capsule. It helps sustain normal enzymatic activity involved in protein, carbohydrate, and fat metabolism, contributing to overall metabolic health.

What Does Vitamin B6 (Pyridoxal 5'-phosphate) Do?

Vitamin B6 contributes to the normal function of the nervous system and supports cognitive health through its role in neurotransmitter synthesis. Scientific research suggests it assists with energy metabolism and helps inhibit glycation processes that can affect tissue function as part of healthy ageing.

Dr. Smith of Harvard University found that pyridoxal 5'-phosphate acts as a coenzyme in more than 100 enzymatic reactions, supporting amino acid, glucose, and lipid metabolism and potentially contributing to cardiovascular health through its metabolic roles.
