These capsules are formulated for the treatment of Kryptopyrroluria (KPU) also known as pyrroluria. Each capsule contains 200mg zinc picolinate, 30mg manganese gluconate, 100mg pyridoxine and 50mg pyridoxyl-5-phosphate. They are also available in a lozenge form for those that suffer from malabsorption problems. This is just a sample formula as we make many variations of it based on the individual. If you are an undermethylator then you should not have any manganese included. We also add biotin, etc in cases where it is needed. Contact us if these options apply to you.
