Pyridoxal-5-phosphate is the metabolically active form of vitamin B-6. It’s involved in numerous body functions, but it is especially important to protein synthesis, such as in the production of neurotransmitters like serotonin and GABA, antibodies of the immune system, oxygen-hungry muscle cells and oxygen-carrying red blood cells. It is also required for proper fluid and electrolyte balance, controlling potassium and sodium based fluids while helping maintain proper intracellular levels of magnesium.

Since it is a water-soluble vitamin, there is no place to store vitamin B-6 in the body over the long-term. Instead, any excess vitamin B-6 gets excreted quickly via urine, within a 60 to 90 minutes of absorption—and under stress, the body will become depleted faster than some diets can replenish.
PureLab’s Slow Release Formulation helps maintain blood levels for 4–5 hours.
PureLab’s Slow Release BioActive B-6 in 50 milligram per capsules ensures a more gradual uptake of the vitamin—in its active form—for a safer way to maintain adequate levels of this nutrient through the day.
