1. The B-Complex with CoEnzymes R5P & P5P, 200 Capsules by Kirkman Labs is a hypoallergenic supplement that provides a comprehensive blend of B vitamins, including R5P and P5P, which are the active forms of vitamin B2 and B6.
2. This supplement has been formulated to support optimal health by promoting energy production, nervous system function, and healthy skin and hair, making it an essential addition to any daily routine.

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

Vitamin B6 in its active form, pyridoxal-5-phosphate, is a water-soluble coenzyme essential for normal metabolic function and nervous system health.

This form supports bioavailability and is often paired with riboflavin-5-phosphate and other B-vitamins to aid cellular processes and liver-related functions.

What Does Vitamin B6 Do?

Vitamin B6 participates in neurotransmitter synthesis and energy production, and assists with homocysteine regulation for normal cardiovascular-related metabolism, in line with EFSA guidance and NHS context.

Dr. Kennedy of the University of Reading reported that active B-vitamins, including P5P, are utilised directly in cellular processes to support these functions.

This formula also has included riboflavin-5-phosphate and other B-vitamins to support overall metabolic health.
