How it works
P5P acts as a cofactor for enzymes that synthesize key neurotransmitters like serotonin, dopamine, GABA, and norepinephrine. It also plays a role in the breakdown of homocysteine, an amino acid linked to neurological and cardiovascular health.
Who should take it
Adults looking to address brain fog, memory decline, attention difficulty. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.

FAQs
Frequently asked
What is the difference between Vitamin B6 and P5P?
Vitamin B6 refers to a group of related compounds, while P5P (Pyridoxal-5-Phosphate) is the biologically active form that the body can directly use for metabolic processes.
How long does it take to see effects from P5P?
Noticeable cognitive effects typically emerge within 2 to 8 weeks of consistent daily use, though individual responses may vary.
Can P5P help with mood?
Yes, P5P is a cofactor for the synthesis of serotonin and dopamine, neurotransmitters critical for mood regulation. By supporting their production, P5P may indirectly benefit mood.
